AI Technical Summary

Technical Problem

The existing test methods do not consider the cavity pressure differences of each lubricant cavity, resulting in a large difference between the test results and the whole machine, and the test is not conducted in combination with the pressure regulating valve, resulting in insufficient matching of the oil supply system and insufficient or excessive oil supply may occur.

Method used

A matching test equipment for oil supply system is designed, including oil supply boosting and temperature regulating flow path, first regulating flow path, main oil supply flow path, branching oil supply flow path and pressure regulating overflow flow path. Through valve switching, a single bearing cavity flow characteristic test and a matching test for oil supply system without pressure regulating valve are realized, and the difference in cavity pressure is taken into account and the working conditions of the pressure regulating valve are simulated.

Benefits of technology

It improves test accuracy and accuracy, reduces the time and economic cost of building multiple test equipment, realizes multi-functional use, and can simulate the cavity pressure of multiple different bearing cavity without adding additional equipment, significantly reducing the test cost.

Abstract

The invention discloses oil supply system matching test equipment which comprises an oil supply pressurizing and temperature adjusting flow path, a first adjusting flow path, a main oil supply flow path and a plurality of branch oil supply flow paths. Throttle valves are respectively arranged in the first adjusting flow path and each branch oil supply flow path, a flowmeter is arranged in the main oil supply flow path, and a switch valve is arranged in each branch oil supply flow path, so that when the measured switch valves and throttle valves of the branch oil supply flow paths are completely opened, a single bearing cavity flow characteristic test is carried out by adjusting the switch valve in the first adjusting flow path. Or when the switch valve in the measured branch oil supply flow path is opened, the oil supply system matching test without the pressure regulating valve is carried out by regulating the switch valve in the flow path and the switch valve in the first regulating flow path, so that the engine oil supply system is simulated to carry out the test when the valve is not connected. According to the equipment, the cavity pressure difference of the bearing cavity is considered during testing, so that the system matching test result is more consistent with the whole machine test, and the test accuracy and the test precision are further improved.
