High flow vacuum self-priming integrated pump

1 High flow vacuum self-priming integrated pumpProduct Overview

High flow vacuum self-priming integrated pumpShanghai Boyu Pump Industry Co., LtdThe company has developed a new product based on market demand, the BYXZXW dual suction pump.High integrationHigh efficiency, energy-saving, smooth operation, long service life and other advantages.Suitable for conveying clean water or mild sewage, with higher efficiency and better self-priming performance than sewage types.It integrates self-priming and non clogging sewage discharge, adopts axial reflux external mixing, and through the design of the pump body and impeller flow channel, it does not require the installation of bottom valves and irrigation water, but can also suck and discharge liquids containing impurities such as particulate solids and fibers. It can be widely used in municipal sewage engineering, lotus pond aquaculture, light industry, papermaking, food, chemical industry, electrical industry, fiber, pulp and mixed suspension and other chemical media impurity pumps. BYXZC type diesel engine self-priming pump is suitable for various complex emergency rescue, firefighting and other occasions, and is not affected by factors such as power supply and usage site. It can be moved for operation and has high flexibility.

IIScope of use

1. The ambient temperature is ≤ 50 ℃, and the medium temperature is ≤ 80 ℃. Special requirements can reach up to 200 ℃.

2. The pH value of the medium is 6-9 for cast iron and 2-13 for stainless steel.

3、BYXZXThe weight of the medium used for W sewage type shall not exceed 1240kg/m3The lift of sewage pumps of the same model is 10% lower than that of clean water pumps

4. The self-priming height cannot exceed the specified value of 5-7 meters, and the length of the suction pipe is ≤ 10m.

5、BYXZXThe capacity of W sewage type suspended particles is about 20% of the pump diameter, and the fiber length is 5 times the pump diameter.

three、Model and Performance Parameters

four、Installation Instructions

1. Before installation, check whether the fasteners of the unit are loose and whether there are foreign objects blocking the flow channel of the pump body to avoid damaging the impeller and pump body during the operation of the electric pump.

2. The weight of the pipeline should not be added to the water pump during installation, and there should be separate support bodies to avoid affecting the operating performance and service life when the pump deforms.

3. When a pump is used to transport hot water or other high-temperature liquids, in order to prevent the pump from being subjected to thermal deformation of the pipeline, the pump may not be fixed with foot bolts. When the pipeline system expands and contracts due to heat, the pump and pipeline can move simultaneously.

4. For the convenience and safety of maintenance and use, a regulating valve should be installed on each inlet and outlet pipeline of the pump, and a pressure gauge should be installed near each inlet and outlet of the pump to ensure that the pump operates within the rated range and ensures its normal operation and service life.

eighty percentStarting, running, and stopping

(1)Start up and operation:

1Check if there is any jamming or abnormal noise when manually turning the motor fan blades before starting.

2Open the water inlet valve above and add at least two-thirds of the pump body's capacity of stored liquid water, then close the valve. In the future, there will be no need to inject water when starting up.

3Connect the power and try turning it on. From the motor end, it turns clockwise. (Reverse is strictly prohibited)

4Before starting, the outlet valve should be opened to eliminate the air in the inlet pipeline. After startingGradually adjust the opening of the outlet valve to ensure that the pump operates within the rated performance range as much as possible.

5If any abnormalities are found during the operation of the pump, it should be stopped immediately for inspection and troubleshooting.

6Check if the motor current value and temperature rise meet the required range.

(II)parking

1Close the valve of the pump output pipeline. 2. Cut off the power and stop the motor from running. 3. Close the inlet valve.

4When the pump is not in use for a long time, the storage liquid should be drained, and when used in cold weather at freezing point, the storage liquid should also be drained to prevent the pump body from freezing and cracking.

self-primingpumpMaintenance and upkeep

Maintenance and upkeep:

（1）checkself-priming pumpIs there any looseness in the pipeline and joints. by handOr toolsrotateself-primingPump, try it outself-primingIs the pump flexible.

（2）Try to control as much as possibleself-primingThe flow rate and head of the pump are within the range indicated on the label to ensureself-primingOnly by operating the pump at the rate point can the maximum energy-saving effect be achieved.
（3）self-primingDuring the operation of the pump, the bearing temperature should not exceed 35C of the ambient temperature, and the maximum temperature should not exceed 80C.

（4）If foundself-primingIf there is abnormal noise from the pump, it should be stopped immediately to check the cause.
（5）self-primingWhen the pump needs to be stopped, first close the gate valve and pressure gauge, and then stop the motor.
（6）self-primingpumpNot having to work with for a long timeWhen using in the cold winter season, after parking, the drain plug at the bottom of the pump body should be unscrewed to drain the medium completely. Prevent frost cracking.(If it is sewage, please clean the pump chamber with clean water)

（7）Listen carefully to the running sound of the electric motor to see if it is abnormaltransportThe noise level in the machine room during operation is relatively high. Auxiliary tools such as screwdrivers or listening sticks can be used to listen to the two ends of the electric motor. If you listen frequently, you can not only discover the electric motor and its dragequipmentThe adverse vibration of the motor can be judged by the amount of internal bearing oil, and corresponding measures such as adding bearing oil or replacing new bearings can be taken in a timely manner to prevent the motor bearings from running out of oil and dry grinding, blocking, running out of the outer circle, and burning out due to sweeping.
