2、 Main advantages:

The design, manufacturing, and inspection of the EKV110 fully automatic kinematic viscosity tester comply with standards such as GB/T265, ISO3104, ASTM D445, etc. Suitable for measuring the kinematic viscosity of transparent and opaque liquids (including crude oil, light and heavy fuel oil, lubricant additives, etc.). The instrument does not require random operation by personnel. After placing the oil sample, the operator sets the oil sample number and position, and starts the test to fully automate the automatic injection and testing. The operation interface is simple, and the system has the advantages of self checking, self diagnosis, and fault prediction.
The instrument consists of three main components: a testing host, a vacuum servo box, and a cleaning servo box; The main components of the instrument are made of imported materials, and the key components are made of imported components, making the instrument more stable and reliable.

The instrument adopts a hardware system consisting of an industrial control computer and a microcontroller. The microcontroller is used to achieve constant temperature control and viscosity testing, with high real-time performance and more reliable test results. The industrial control computer is used as the overall system control, making the instrument more reliable. The industrial control computer has 1GB of memory and 4G of hard disk, which not only runs fast but also has a large data storage capacity. Adopting the Windows XP operating system and a fully Chinese interface (which can be replaced with an English interface), it is convenient for users to operate and provides multiple communication interfaces (RS-232, USB, RJ-45, etc.). It can connect to LIMS system and browse the Internet through LAN.

● Equipped with WIFI and Bluetooth.

The operation interface consists of a TFT LCD display screen, touch screen, metal waterproof keyboard, and trackball.
Single constant temperature bath, dual viscosity meter design, constant temperature range: 20 ℃~100 ℃, adjustable throughout the entire range.
The measurement range of kinematic viscosity is wide, and each viscometer is designed with three detection bubbles, with a viscosity measurement range of 100 times. The instrument includes two viscometers, each of which is calibrated using American Keneng kinematic viscosity standard oil before leaving the factory. The instrument system software itself also has calibration function, and users can calibrate using standard oil. The viscometer uses two types of viscometers (thermistor detection method and photoelectric detection method), making the detection range wider.
The automatic injection system is equipped with two injection trays, each with 12 injection holes. Users can load 24 oil samples at once for testing; Each injection tray can be preheated, with a high preheating temperature of 70 ℃.

● Instrument testing process: Manually place the sample on a tray - tray automatic injection-Automatic sampling-Automatic sampling-Automatic constant temperature immersion - automatic viscosity testing-Automatic cleaning - automatic blow dryingThen automatically make the next sample and repeat the above automatic testing process.

Automatic samplingThere are one sample tray on each side, and users can place 1-12 oil samples in each tray. Based on the input sample cup number, the instrument will automatically search for samples;

Automatic samplingThe instrument will automatically lift the sample cup up to the suction nozzle of the viscosity tube, sample automatically through vacuum negative pressure, and stop automatically after reaching the upper limit of the detected bubble. Users can also set the delay time for sample suction;

Automatic constant temperature immersionAfter the instrument draws the sample, keep the oil sample in the viscosity tube and immerse it in a constant temperature bath. The temperature of the constant temperature bath and the constant temperature immersion time of the sample are set by the user before the experiment;

Automatic viscosity testingAfter the automatic immersion of the instrument is completed, it will automatically open to the atmosphere and start to fall freely for testing. It will automatically detect the liquid level position and record the dripping time. After completing the next test, it will automatically proceed to the next test. The number of tests for each oil sample is set by the user, 2-4 times. Automatically calculate the kinematic viscosity based on the number of tests and take the average value to obtain the result;

automatic cleaningAfter completing each oil sample test, compressed air is automatically injected into the cleaning agent for automatic cleaning. The cleaning time and frequency are also set by the user before the test. Cleaning includes two channels, cleaning A and cleaning B. Usually, one cleaning agent is used as standard, and the user can choose to use cleaning A or cleaning B, or both cleaning A and cleaning B;

Automatic dryingAfter cleaning, the instrument will automatically dry using compressed air, and the number and duration of drying will be set by the user,

The above is the experimental process, and each state system will display it;

The industrial computer monitors the entire testing process, and the system has automatic diagnosis and fault alarm functions, as well as overheat protection and power-off protection functions.
