Problems solved by technology

As the viscosity of the hydraulic oil decreases, the lubricating oil film produced by the hydraulic oil on the working surfaces of the aircraft hydraulic system will gradually become thinner, and the lubricating effect will gradually deteriorate, resulting in increased friction and wear inside the system, resulting in more wear particles.

Abstract

The invention discloses an aviation hydraulic oil viscosity attenuation control index test system and a test method. The test system comprises a monitoring device and a test platform for the mountingof a tested hydraulic pump, and the test platform comprises an oil tank used for supplying oil to the tested hydraulic pump, a heating and cooling module used for controlling the temperature of the return oil of the tested hydraulic pump, a filter used for filtering the return oil of the tested hydraulic pump and connected to the oil tank, and an on-line oil viscosity sensor used for detecting theviscosity of the return oil of the tested hydraulic pump. The test method comprises the following steps: (1) before testing, the tested hydraulic pump is mounted, and whether the tested hydraulic pump is normal or not is judged; (2) a viscosity reference value and a metallic element content reference value are detected; (3) a viscosity attenuation control index is detected. The aviation hydraulicoil viscosity attenuation control index test system has the advantages of simple structure, reasonable design, easiness in use and operation and good use effect, and can easily and quickly carry outthe testing of an aviation hydraulic oil viscosity attenuation control index, and moreover, the testing precision is higher.

Description

technical field [0001] The invention belongs to the technical field of testing the viscosity attenuation control index of aviation hydraulic oil, and in particular relates to a testing device and a testing method for the viscosity attenuation control index of aviation hydraulic oil. Background technique [0002] The aircraft hydraulic system uses aviation hydraulic oil as its working medium. In addition to transmitting hydraulic energy in the aircraft hydraulic system as a working medium, aviation hydraulic oil also lubricates the working surfaces in the aircraft hydraulic system to protect the working surface from oxidation. . With the operation of the aircraft hydraulic system, the relative movement of the internal working surfaces will produce metal particles; various seals will gradually produce non-metallic particles as they age or work, and these particles enter the hydraulic oil and flow downstream with the hydraulic oil , and filtered by oil filter. Therefore, hydr...
