Automatic Lubricating Oil Evaporation Loss Tester

Abstract

The invention provides a fully automatic lubricating oil evaporation loss tester, which includes a tester body, an electric heating element, an evaporation crucible, a temperature sensor, a pressure sensor, an inclined differential pressure gauge, a pressure controller, a vacuum pump, a primary buffer bottle, Secondary buffer bottle, filter, silicone tube II, silicone tube III, silicone tube IV, glass branch pipe I, glass branch pipe II, glass branch pipe III, Y-shaped glass tube, evaporating crucible extraction tube, glass tee pipe; The tester body includes the tester shell and supporting plate, the central processing unit and the control circuit. The invention develops an instrument for measuring the evaporation loss of lubricating oil and grease base oil for the scientific research, production and use of lubricating oil. By adjusting parameters such as temperature, pressure, and air flow rate under specific conditions, the lubricating oil Fully automatic determination of evaporation loss values.

Description

technical field [0001] The invention relates to a detecting device for detecting the evaporation loss value of lubricating oil and lubricating grease base oil. Background technique [0002] In the lubricating oil and grease industry, the evaporation loss value of lubricating oil is an important index in lubricating oil parameters, and it is one of the important basis for evaluating the lubricating effect and life of lubricating oil. At present, the domestic determination of the evaporation loss of lubricating oil and grease base oil The manual test method is still used to test the value, and Wood alloy is used as the auxiliary heating medium. This measurement method has the following disadvantages: 1. During the manual test, the pressure parameters need to be adjusted by manual observation. Manual negligence can easily lead to abnormal pressure, and the adjusted value is stable. Poor performance, which affects the accuracy of the test results; 2. Using Wood alloy as the heat...

[0002] In the lubricating oil and grease industry, the evaporation loss value of lubricating oil is an important index in lubricating oil parameters, and it is one of the important basis for evaluating the lubricating effect and life of lubricating oil. At present, the domestic determination of the evaporation loss of lubricating oil and grease base oil The manual test method is still used to test the value, and Wood alloy is used as the auxiliary heating medium. This measurement method has the following disadvantages: 1. During the manual test, the pressure parameters need to be adjusted by manual observation. Manual negligence can easily lead to abnormal pressure, and the adjusted value is stable. Poor performance, which affects the accuracy of the test results; 2. Using Wood alloy as the heating medium, when it is heated to the melting temperature, it will produce toxic vapors that will be emitted into the space, causing harm and impact to the testers and the environment, and in severe cases will cause testers Poisoning

3. The test cycle is long (the whole process is more than 1 hour), and the whole test process needs to be observed and adjusted by the testers at all times, which consumes a lot of manpower: 4. The difference in the testing energy and testing experience of the testers will lead to great differences in test results , unable to meet the accuracy, repeatability and reproducibility required by relevant standards
