Description

technical field [0001] The invention relates to the technical field of hydraulic detection equipment, more specifically, it relates to a detection system for overcoming the temperature rise of hydraulic oil during the hydraulic detection process. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). Its structure is simple and its work is reliable. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable. Therefore, it is widely used in various mechanical hydraulic systems. When the hydraulic cylinder leaves the factory, it needs to be tested for oil performance, that is, it is installed on the test equipment to simulate the actual working conditions and check whether it can work normally. Hydraulic temperature needs to be controlled in hydraulic te...

Problems solved by technology

[0004] Although the above technical solution solves part of the problem of temperature rise, the hydraulic pressure source in the system still comes from the hydraulic pump, and the long-term detection makes the hydraulic pump work for a long time, which causes the temperature of the hydraulic pump to rise, and the heat transfer leads to the loss of hydraulic oil. The temperature rises, which in turn affects the detection accuracy of the entire detection system
