A detection system to overcome the temperature rise of hydraulic oil in the process of hydraulic detection

Abstract

The invention discloses a detection system for overcoming the temperature rise of hydraulic oil in the process of hydraulic detection, which belongs to the technical field of hydraulic detection equipment. The pressure oil supply device and the measurement and control device for detecting the output pressure of the hydraulic cylinder. The oil supply device includes a single-acting piston cylinder and a driving structure that pushes the piston cylinder to expand and contract. The oil inlet is connected, the rodless chamber of the single-acting piston cylinder is filled with hydraulic oil, the installation frame is fixedly connected with the cylinder body of the hydraulic cylinder under test, and the detection end of the measurement and control device is in contact with the piston rod of the hydraulic cylinder under test end face. The invention has the effect of reducing the temperature rise of the hydraulic oil so as to improve the detection accuracy.

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
