Oil plant detection is also known as POL test, is to various vehicle fuels, lubricating oil, lubricating grease, automobile production machining medium
The detection of performance indicator.
Viscosity is derived from the interior friction of liquid.Oil liquid generates between oil molecule by external force and when relatively moving
Resistance, make oil liquid that can not be well on flowing, drag size is known as viscosity.The measure of viscosity be divided into absolute viscosity and
Relative viscosity two major classes.Wherein absolute viscosity is divided into dynamic viscosity and two kinds of kinematic viscosity.Kinematic viscosity is the important of lubricating oil
One of index can reduce generator power if viscosity is excessive, if viscosity is too small, will increase wear and tear in machines.It is also insulation
One of oily important indicator, viscosity is lower, and transformer circulating cooling effect is better.
Existing kinematic viscosity detector commonly uses following methods and measures oil viscosity: in the tight temperature controlled and give
Under, the oil plant for determining volume is flowed down from the graduated capillary of viscosimeter under interchangeable driving head under the effect of gravity, test
Time out.Kinematic viscosity is the flowing time measured and the calibration constants of viscosimeter.
As disclosed in the Chinese patent of Publication No. CN206920280U " kinematic viscosity analyzer ", including constant temperature bath dress
It sets, control system, stirring system and viscosimeter, constant temperature bath device includes glass inner casing and glass outer shell, in glass
Chuck layer is formed between cylinder and glass outer shell, and transparent protective cover is provided in constant temperature bath device, is provided in transparent protective shield

It is connect on device and with control cabinet, viscosimeter includes the fixed frame being arranged at the top of constant temperature bath device and passes through solid
Determine the capillary that frame is fixed in constant temperature bath device, capillary is U-shaped structure, and constant temperature bath device is run through at the both ends of capillary tube
Top.
The time that liquid flows through capillary glass tube under the effect of gravity is different at different temperature, and viscosity is bigger
Product this species diversity be more obvious, so the kinematic viscosity value under a certain specific temperature is obtained, to the temperature of its constant temperature bath
Control has high requirement.
The current oil product standard movement viscosity test in China only proceeds to 100 DEG C, is higher than to temperature 100 DEG C (especially high
In 130 DEG C) oil product kinematic viscosity, the reproducibility of oil testing is bad etc. under the sealing performance and high temperature in view of domestic test equipment
Problem tends not to obtain ideal test result.
In fact, 100 DEG C or more of machine oil kinematic viscosity not only characterizes the flow behavior of itself, the also work to diesel engine
Condition performance (diesel engine lubricating oil temperature is generally all at 100 DEG C or more) has certain connection, as engine oil consumption parameter often with the fortune of machine oil
The parameters such as kinetic viscosity, evaporation loss are proportional.So the machine oil kinematic viscosity of 100 DEG C of research or more has more important meaning
Justice.
