DGN1000×C6Automatic rapid determination instrument for crude oil water content

Preface

DGN1000×C6The series crude oil water content automatic rapid measuring instrument is the latest and most automated crude oil water content measuring device. According to the latest national measurement standards, in productionDGN500Under the premise of the model, it has been developed againDGN1000The type of crude oil water content rapid measuring instrument not only overcomes the disadvantages of traditional measuring instruments such as difficult temperature control, easy sample flushing, high energy consumption, low efficiency, and insecurity.

The product has been tested by experts from Shengli Oilfield and Zhongyuan Oilfield, and it is believed that this instrument has complete performance, high degree of automation, safety, energy saving, and easy operation. It is a reliable instrument for various oil production manufacturers, gathering and transportation stations, scientific research units, and oil post laboratories.

1DGNCharacteristics and working principle of a series of rapid crude oil water content measuring instruments

1. This instrument adopts a heating sleeve for non open flame heating, with fast heating, low power, uniform heating, and high efficiency.

2. Magnetic stirring is a closed magnetic stirring method that avoids sudden boiling and achieves rapid oil-water separation.

3. In the automation and self-control parts, the timer is the heating power switch, which sets the required time. Once the time is up, the heating power will be automatically turned off, the cooling system will be started, and the cooling fan will start working automatically. By using gas sensing probes instead of manual monitoring, if the height of oil and gas rise exceeds the specified standard, the instrument automatically cuts off the power supply and starts the axial flow fan to quickly cool down the furnace body, thereby avoiding the phenomenon of sudden boiling and sample collision and achieving safety.

4. Equipped with a pure water automatic cooling tank, it prevents the yellowing and scaling of glass instruments, and solves the problem of water shortage in field operations.

5DGNOptional glass instrument quick drying oven. In order to address the impact of external cold air on the receiver, it is equipped with a temperature protection device, which solves the problem of premature condensation of water vapor and backflow of water droplets, achieving the goal of rapid evaporation of moisture.XAHot air flow rapid constant temperature dilution instrument, which can be heated at once6It can also dry glass instruments.

2、 Indicate

This instrument relies on high-temperature distillation to increase the temperature of crude oil, so that the temperature of water in the oil reaches100Above the temperature, it turns into steam and is magnetized to allow the iron substances in the oil to rotate at high speed, causing the emulsified water to quickly separate and the water in the oil to evaporate rapidly, achieving the goal of rapid measurement. Therefore, the diluent added should not exceed150gram(Sampling)200gram）Otherwise, a large amount of light component gases will quickly enter the condenser tube, and once they encounter the gas sensing probe above, the instrument will automatically stop heating and enter a cooling state, which will not achieve the rapid effect. Due to differences in scale, facilities, and workload among different units,DGNThe series of crude oil water content measuring instruments are equipped with the following specifications for reference:

Due to different water contents in crude oil, the sampling amount also varies100gramCrude oil, can be diluted with diluent40gram－50gramTake crude oil50gramAdd diluent30gramThe distillation time remains unchanged,DGN1000型取原油100gramDiluent60gram.

The purpose of crude oil determination is to completely separate oil and water and accurately measure the water content of crude oil. Therefore, whether it is rapid or long-term distillation, only by measuring accurate values can the requirements be met. Users can adopt this methodDGN500Comparative experiments were conducted between the measurement results of the series products and other instruments, and practical experience has proven that the use ofDGN500Type of instrument only used20In minutes, the original instrument can pass through60－90Accuracy measured in minutes, saving solvents2.6Double energy-saving5times,Improved work efficiency4More than double,If users have strict regulations on distillation time and solvent dosage, they can also conduct experiments according to their own methods. Using this product to add400gramSolvent gasoline(xylene)The specific operation method for long-term distillation remains unchanged,Just adjust the voltage to150VJust enough. Our factory implements three guarantees for our products from the date of shipment, and is responsible for training and installation,Free two-year warranty and on-site service.

3、 Combination installation

1. Main components:

The main body of the instrument includes: rapid measuring instrument, condenser bracket, purified water automatic cooler, glass moisture analyzer, cooling water conduit, etc.XAThe hot air flow crude oil rapid constant temperature dilution instrument is an important accessory.

2. Place the measuring instrument in the appropriate position, and then fix the condenser bracket on the screw behind the measuring instrument.

3. The condenser bracket is a push-pull bracket. During installation, the entire set of glassware can be placed inside the heating sleeve to check if it is vertical. If it is not vertical, the bracket ring can be moved left and right to correct it, achieving free loading and unloading, and then the screws can be tightened. The tightness of the condenser tube clamp should be such that the condenser tube can slide up and down freely.

4. Connection of cooling water conduit: The connection method can be series or parallel, which refers to the connection between the first set of upper and second sets of lower ports of the condenser circulating water outlet, the connection between the second set of upper and third sets of lower ports, the connection between the third set of upper and fourth sets of lower ports, the connection between the fourth set of upper and fifth sets of lower ports, and the connection between the fifth set of upper and sixth sets of lower ports. Then connect the remaining first set of lower ports to the condenser outlet, and connect the upper port of the sixth set to the cooler return pipe. The other six groups are also connected and can be connected in parallel with it.

6. Connection of the cooler: Turn off the two switches on the cooler panel, plug the power plug directly into the power socket on one side of the cooler, and connect the other end to an AC power source. Add about three-quarters of water into the stainless steel copper. Then turn on the switches separately and test the circulating water and cooling compressor separately. When testing the circulating water pump, immediately listen to whether the pump starts after turning on the switch. If it does not start, there will only be a slight sound, which is often caused by long-term disuse. The impeller inside the pump is stuck and cannot rotate. The power supply of the pump should be turned off immediately to prevent the pump from being burned out by prolonged power on. Use a small stick about 30 centimeters long at the outlet to gently poke the impeller inside the pump to make it move, and then turn on the power for testing. Some water pumps come with a movable screw at the end of the factory, so there's no need to poke it with a small stick. Just use a screwdriver to tighten it.

4、 Operation Guide

1、 Introduction to the functions of panel components：

1On the far left of the instrument is the 'Voltage Indicator', which can reflect the level of voltage regulation.

2The voltage indicator instrument has a "power switch" on its right side and a "power indicator light" on top of the power switch. When the power switch is turned on, the indicator light is on.

3On the upper right side of the power switch is the 'timer indicator light', which lights up when the timer instrument is working. The black knob below is the 'Voltage Regulator', which can adjust the power supply voltage by rotating it. This can be directly reflected on the voltage indicator on the far left side of the panel.

4The two 'digital timing instruments' on the left and right, as well as the' temperature display control instrument ', are both used for automatic control, enabling automatic switching between heating and cooling. The main function of digital timing instruments is to automatically record and control experimental time. The temperature display control instrument is an intelligent regulating instrument, whose main function is to provide protection and prevent sample flushing when the heating temperature is too high.

5The "Mixing Switch" is the power switch of the magnetic stirrer, and the black knob on its right is the "Speed Control Knob" of the magnetic stirrer. By rotating it, the speed of the stirrer can be adjusted.

6The red switch on the digital timer is the "manual and automatic switch" for heating and cooling; When heating is not required, it can be manually switched to sample cooling. Usually, this switch is in the automatic position.

7The 'temperature rise indicator light' lights up when the electric heating sleeve is heated and goes out when the heating sleeve stops heating. The 'cooling indicator light' goes off when the electric heating sleeve is heated and lights up when the heating sleeve stops heating. At this point, the fan runs automatically.

8Look to the right: from left to rightⅠ、Ⅱ、Ⅲ、Ⅳ、Ⅴ、ⅥSix switches and indicator lights correspond to the six heating sleeves from left to right on top.

5On the back of the instrument:① GreenThe socket is a temperature sensing probe socket for intelligent control instruments. When using it, align it with the anti error slot inside and slowly apply force to insert all the parts that should be inserted. Do not operate it forcefully, otherwise it will damage the socket. If it is not plugged in, the instrument will not heat up, only cool down and blow air.②Power cord connection220Voltage power supply.

2、 Usage:

1. The power of each thermal group of the instrument is equal, and there is only one probe. When in use, after each group of oil samples is prepared, they must be loaded into the heating sleeve of the instrument and heated for distillation at the same time, otherwise the timer will lose its timing function.

2. The loading and unloading methods of the flask, receiver, and condenser tube: After the crude oil and diluted gasoline are loaded, the flask must be held by hand, and the receiver must be inserted into the flask with the left hand. Observe whether the grinding mouth of the flask and the grinding mouth of the receiver are tightly combined, otherwise there will be air leakage. Use your left hand to push the condenser tube up to the top stop, and your right hand to push it up. Insert the grinding mouth on the top of the receiver and the grinding mouth on the bottom of the condenser tube tightly together. Align your left and right hands with the heating sleeve and apply slight force until the bottom of the flask and the bottom of the heating sleeve are tightly combined.

3. The usage method of automatic control probe: The probe is a substitute for manual monitoring of guards.Its principle is that oil and water are heated, and the oil and gas rise and come into contact with the probe to function. When in use, it must be inserted into the upper opening of the heating condenser tube1/3Otherwise, automatic control cannot be used. The digital temperature control meter corresponding to the probe, such as a "voltage regulating instrument", should generally set the temperature at60Degree. For instruments without voltage regulation, the temperature should be set at35The temperature can be adjusted according to the actual situation of the oil sample, such as when the oil sample reaches the condenser tube, to accelerate the separation of oil and water3/4You can set the temperature of the temperature control instrument lower, for example, if the oil sample does not flush into the condenser tube1/2You can set the temperature of the temperature control instrument higher, which is related to the ambient temperature and oil sample density. Therefore, it needs to be flexibly applied. The adjustment of the intelligent temperature control meter is explained at the end.

Note:Be sure to see the convex groove on the probe clearly, align it and apply slight force, and slowly insert it. If the probe is not inserted into the instrument, the instrument cannot function properly. However, after inserting the probe, it can be placed behind the instrument instead of in the condenser tube.

4. Timer operation method: The timer is the power switch for heating, blowing, and cooling of the instrument. When using, first adjust the middle time of the digital device in the timer(h)divide(m)second(s)Set the time again, the digital display will start counting from zero when the power is turned on. Once the set time is up, the heating will automatically stop and the blowing and cooling will begin. The digital display will maintain the current number, achieving timed control. Reset the time, or turn on the reset switch on the left side of the timer at any time, and then immediately turn it off to start counting again from zero.If you don't want to time, you can set the time to the maximum99hour.

The significance of time numbers:

①When the middle of the digital device is set to（h）The hour represents the hour, and the timing range is1Divide -99hour99Minutes (the preceding digits represent hours, and the following digits represent minutes).

②When the middle of the digital device is set to（m）The time table is divided, and the timing range is1In seconds -99divide99Seconds (the first digit represents minutes, the last digit represents seconds).

③When the middle of the digital device is set to（s）Chronometer seconds, timing range is0.01In seconds -99.99Seconds (the preceding digits represent seconds),The numbers behind represent0.01Seconds).

The upper window of the timer displays the timer, and the lower window displays the time setting. When setting the time, press the setting button once, as shown inh-nThe light on indicates the set hour-Minute, press the set button againn-sThe light on indicates the set minute-Second, press the set button agains-msThe light is on, indicating the set second-One hundredth of a second. Press the setting button again to cycle to the hour-The division has been set. After setting, press the selection key to save and exit the start timer. Press the pause button to stop timing, then press the pause button again to start timing from the previous one. The reset button will start timing from zero.

The significance of time numbers:

①When the digital device is set to（h）The hour represents the hour, and the timing range is1Divide -99hour99Minutes (the preceding digits represent hours, and the following digits represent minutes).

②When the digital device is set to（m）The time table is divided, and the timing range is1In seconds -99divide99Seconds (the first digit represents minutes, the last digit represents seconds).

③When the digital device is set to（s）Chronometer seconds, timing range is0.01In seconds -99.99Seconds (the preceding digits represent seconds),The numbers behind represent0.01Seconds).

5. Voltage adjustment method: Voltage adjustment is also an adjustment of heating power. The first use can adjust the electricity to110-160VBetween (observe the reading scale of the instrument voltmeter). After heating for five minutes, observe the height of the oil and gas rising in the condenser. Generally, the height should be in the middle of the condenser. If you cannot reach this height, you can slightly adjust the pressure knob clockwise until the oil and gas are stable1/2Stop here. Remember this reading, use it again next time, adjust it according to this voltage once, and generally do not touch it.

6. The usage method and regulations of the mixer: There are two types of this instrument: full mixing and single group mixing. It is determined based on the amount of oil taken. This instrument has two stirring functions, one is magnetic stirring and the other is iron ion stirring. If taking crude oil50gramBelow, only one stirrer is placed in each instrument, and the designated set of heating flasks is sufficient. Other groups do not need to have agitators, just rely on the iron ions in the crude oil to stir. If taking crude oil100gramEach group must have a stirrer. Each bottle can only contain one mixer.

7. Method to start stirring: Due to the continuous rotation of the stirring magnetic field, the temperature and viscosity of the crude oil just added are very low, and the stirring element is stationary. At this time, the stirring element may not necessarily rotate. After heating for 1-2 minutes, the crude oil is diluted, and then press the magnetic stirring switch downwards,Gently turn the speed control knob, and all mixers will start up.

8. Comprehensive use and inspection: After connecting the power, turn the function key to the automatic control position, and the instrument power indicator light will turn on, indicating that the power has been connected. When each group needs to heat and distill the oil sample, put it into the heating sleeve of the instrument, turn on the switch of each group that needs to be heated upwards, and set the timer15－20minute The heating indicator lights for each group that require heating are on, indicating that it is working. When the set time is up, it will automatically shut down and the reading will be ready.

6、 Emergency troubleshooting

1. If the operation is improper or too much oil is taken, the diluted gasoline preparation is incorrect, causing sample flushing and crude oil flushing into the receiver, manual control can be used: immediately turn the function switch to the sample cooling position. The instrument will automatically power off and at the same time turn on the fan to quickly cool down the heating part through air cooling. Distillation can continue after the temperature drops.

2. During the distillation process, if blue smoke is found to be emitted from the heating jacket, it indicates that the bottom of the flask has exploded. The heating jacket must be turned off and the flask must be removed. Do not continue distillation. If crude oil has already flowed into the heating jacket, after the distillation of other groups is completed, adjust the voltage to70V. Slowly heat and evaporate until there is no smoke before continuing to use. Otherwise, this heating sleeve will quickly burn out.

3. Whether the crude oil has been completely distilled can be checked by whether there are water droplets on the inner wall of the flask. No water droplets indicate that the water in the oil has completely evaporated.

7、 Precautions

　　　1. Before use, it is necessary to carefully read the instruction manual. Operate according to the instructions, do not open or ask other manufacturers for repairs without authorization, otherwise our factory will not be responsible.

2. It is normal to have white smoke and odor during the first use.

3. Due to differences from traditional distillation methods, the cooling water flow rate must be increased, and it is strictly prohibited to change the gasoline dilution ratio of the new distillation method.

4. This instrument is for rapid distillation and cannot be used30centimeterThe fine mouthed (12 #) condenser must be used19Moisture analyzer with the above caliber.

XA type hot air flow crude oil rapid constant temperature dilution instrument

Instructions for Use

　This product is the latest specialized equipment for rapid heating and dilution of crude oil, which has the advantages of speed, constant temperature, safe use, and simple operation. In addition, it also has functions such as quick drying of flasks and receivers.

Instructions for use

1 Connect the power, set the digital device to the desired temperature, plug in the power, turn on the switch, and then you can see the detailed temperature rise inside the box on the digital screen. When the temperature rises to the set temperature, the power supply immediately shuts off and stops heating; When the temperature is lower than the set temperature, the power automatically turns on again, and heating begins to enter a constant temperature state. To prevent the evaporation of crude oil moisture, it is best not to set the temperature above 60 degrees Celsius. When using samples urgently, it is possible to set the temperature below 100 degrees in a short period of time. When not in use, unplug the plug.

2 Receiver drying: The used receiver contains many water droplets. To ensure accurate analysis, the receiver is plugged into the hot air pipe of the diluter for drying. If it is urgently needed, it can be directly placed in a constant temperature box for rapid drying.

3 After the laboratory procedure is completed, the crude oil in the sampling bucket needs to be poured out. The sampling bucket can be reversed to allow the waste oil to naturally enter the receiving tray, which can save a lot of gasoline.

Precautions

1. It is strictly prohibited to open the lid for heating.

2. It is strictly prohibited to use this product to dry other products.

3. When using, the oil pan must be pushed inward.

4. It is strictly prohibited to heat the sample barrel at high temperature for a long time.

5. The storage oil in the receiving disk should not be too much. If it is too much, the disk should be removed and the oil should be poured out.

Purified water cooler

Introduction

The purified water cooler is a self-contained water source for the WN500 series products. This accessory saves water and is most suitable for use in laboratories with no water pipelines, no pressure in water pipes, and poor water quality. Using purified water for circulating cooling, the glassware does not turn yellow or scale, and pure water is added20 kilogramsIt can be used for one year and is the best auxiliary facility for the WN series rapid measuring instrument.

Instructions for use

1. Before use, add purified water to the water storage tank (level line to 3/4 of the tank). If used in conjunction with other products, please insert the product's three pole plug directly into the power socket. The power light is on, indicating that the power is turned on. Turn the switch up to the ON position, and the water pump will start working. When using in summer, the cooling switch should be turned on to cool down.

2If used in conjunction with the WN series crude oil analyzer, the three pole plug of the product can be directly inserted into the output socket of the analyzer, and then the switch of the product can be turned to the ON position. Both on and off are automatically controlled by the analyzer.

3. Water change method: When changing water, there is no need to pour out the water, just pull out the return pipe and turn off the machine after the water is drained. Pour purified water into the tank. At this point, the water in the condenser may not be completely drained. Turn on the machine again, use purified water to drain the remaining residual water in the condenser, and then insert the return pipe into the tank.

Precautions

1. When using, the water valve and cooling valve must be opened to the maximum position. Do not close the cooling valve, otherwise it will burn out the water pump motor.

2. When installed for the first time or not in use for a long time, the suction pipe is dry and it is likely that there will be no water coming out after starting up.

3. Solution: The water absorbing faucet can be removed and about 1 kilogram of water can be added to it for normal operation.
