Q1: What is a viscometer?
A1: A viscometer is an instrument used to measure the viscosity of fluids (liquids and gases). Viscosity is a physical quantity that indicates the internal friction within the fluid when the fluid is flowing. It is the ability of the fluid to resist deformation. It is an important indicator used to identify some finished or semi-finished products. Viscosity varies from fluid to fluid and varies with temperature. There are mainly three types of capillary viscometers, rotational viscometers and falling ball viscometers.
Q2: What is the definition of viscosity?
A2: When a liquid is flowing, the property of internal friction between its molecules is called the viscosity of the liquid. The viscosity of the liquid is expressed by viscosity, which is a resistance factor used to characterize the properties of the liquid. The viscosity of insulating oil is the same as the viscosity of general liquid, that is, the internal friction of the liquid, that is, when the insulating oil moves relative to laminar flow under the action of external force. The properties of insulating oil molecules that generate internal frictional resistance. The greater the internal friction of the insulating oil, the greater the viscosity, the more difficult the flow, and the poorer heat dissipation performance.
Q3: What is a viscometer used for?
A3: Viscosity is an important physical parameter used to measure the ability of liquids to resist flow. Using a viscometer to measure the viscosity of a liquid is an important means of industrial process control, improving product quality, and saving and developing energy. It is closely related to the fields of petroleum, chemical, electric power, metallurgy and national defense. Status plays an important role.
Tips for installing viscometer
- Care should be taken when loading and unloading the rotor. When loading and unloading, the connecting screw should be slightly lifted for operation. Do not use too much force, and do not force the rotor laterally to prevent the rotor from bending.
- Please do not put the viscometer with the rotor installed on its side or upside down.
- The connecting end face and thread of the connecting screw and rotor should be kept clean, otherwise the shaking of the rotor will be affected.
- The viscometer should be supported by hand when it goes up and down to prevent the viscometer from falling due to its own weight.
- After replacing the rotor, please input the new rotor number in time. After each use, the replaced rotor should be cleaned (wiped clean) in time and put back in the rotor holder. Please do not leave the rotor on the instrument for cleaning.
- When changing the liquid under test, please clean (wipe clean) the rotor and the rotor protection frame in time to avoid measurement errors caused by the confusion of the liquid under test.
- Viscometers and rotors are matched one-to-one, please do not confuse several instruments and rotors.
- Please do not disassemble and adjust the instrument parts at will.
- When moving and transporting the instrument, put the yellow cap on the connecting screw, tighten the screw, and put it in the packing box.
- After installing the rotor, please do not rotate it for a long time without liquid, so as not to damage the shaft tip.
- Many of suspensions, emulsions, polymers and other high-viscosity liquids are "non-Newtonian liquids", and their viscosity values vary with conditions such as shear speed and time. The inconsistency between the results measured under time and time is a normal situation, not an instrument error. The determination of non-Newtonian liquids should generally specify the rotor, speed and time.
