Kinematic viscosity Tester This instrument is manufactured in compliance with the requirements stipulated in the People's Republic of CHINA industry standard SY/T 5651 "Technical Conditions for Petroleum Product Kinematic Viscosity Tester" and is suitable for use in accordance with the People's Republic of CHINA standard GB/T 265 "Petroleum Product Kinematic Viscosity Tester". According to the provisions of "Method for Calculation of Dynamic Viscosity", the kinematic viscosity of liquid petroleum products (referred to as Newtonian liquids) under a certain constant temperature condition is determined.

Main features

1. This instrument adopts the form of an all-in-one machine, and the control switch adopts the form of light touch keys. It has a novel design, compact structure, and elegant appearance.

2. Adopting intelligent LCD display temperature controller, the temperature control is rapid, the response is fast, the overshoot is small, and the temperature control accuracy reaches ±0.1℃.

3. Using a hard glass jar and electric stirring device, the sample can be observed clearly and the temperature in the bathtub is uniform.

4. The characteristics of this instrument are: fully sprayed, durable; ultra-thin LCD temperature controller, novel and outstanding; small desktop structure, beautiful and generous; Pinnacle capillary viscometer type.

Use actions

1. After connecting to the power supply, turn on the "power" switch, and the instrument starts to work as a kinematic viscometer. The temperature of the working medium in the bathtub is controlled by the temperature controller. At the same time, the stirring is started to stir the medium.  

2. When performing a viscosity time test, press the timing button and the digital display will start timing; press it again and the timing will stop; the instrument automatically calculates the kinematic viscosity value.  

3. Press the corresponding buttons on the instrument to set the test temperature and capillary constants, and when the temperature is stable at the test temperature point, the test can be carried out.  

Maintenance routine 

1. When turning on the machine, be sure to turn on the power first and then turn on the power switch; when shutting down, be sure to turn off the power switch first and then turn off the power.  

2. The rotor should be cleaned after use and placed neatly in the black rotor box.  

3. Keep the connection between the rotor and shaft clean and free of sample.  

4. If it is not used for a long time, a protective cap should be placed on the bottom of the shaft.  

5. Calibrate regularly with standard silicone oil.  

daily inspection

1. When turning on the instrument, check whether the model displayed matches the label on the back of the instrument. After the automatic zero adjustment is completed, observe whether the torque display percentage is between +/-0.2. And turn the shaft by hand to observe the number of swings, which is more than 6 times for the LV model and about 5 times for the RV model, and there will be no sudden stop. If all the above checks are normal, it can be used normally.  

2. Set the rotation speed at 100RPM, idle without installing the rotor, and observe whether the rotation of the rotating shaft is concentric and there is no large swing. 

Failure evaluation

1. Wear of steel tips and jewel bearing seats: This is a very common failure. The steel tip and gem holder are used to support the weight of the viscometer's sensor, rotating shaft, and rotor. Under normal circumstances, they should be smooth and have very little friction. However, due to long-term contact and running-in between the two or careless operation, the steel tip is worn hard. Damage to the surface of the gem holder will cause the surface of the gem holder to become uneven, which will make the contact between the two not at one point but on one surface, increasing the frictional resistance and thus affecting the accuracy of the instrument. There will be a phenomenon on the operation display of the instrument that the torque is not "0" after the power is turned on (the dial shows that the pointer is not "0").  

2. Bent shaft: It may be caused by collision or deformation of the shaft after being used for a long time. This faulty instrument shows that when idling at 100RPM, the rotating shaft shakes greatly. Generally, if the rotating shaft deviates from the axis by more than 0.8mm, it needs to be repaired and replaced.  

3. The panel is out of control: This situation is caused by long-term use and long-term pressing of the keys, causing the keys to lose their function and be damaged.  

4. After turning on the machine and performing zero calibration, the instrument displays not "0" but a negative number. This is because the customer did not remove the rotor from the shaft before automatic zero calibration, or the rotor has been immersed in the sample.  

5. During measurement, the instrument displays "EEEE", indicating that the measurement exceeds the "large measurement range". This is caused by improper matching of the rotor or speed selected for measurement.  

6. PCB board damage: Due to the unstable power supply used by some customers, the instantaneous Voltage is too high, which burns out the power board or display board, causing the computer to be unable to boot or display data. At this time, a new circuit board needs to be replaced.
