Embodiment

[0038] Embodiment: a detection system that overcomes the temperature rise of hydraulic oil in the hydraulic detection process, such as figure 1 As shown, the oil supply device 100 and the measurement and control device 200. The oil supply device 100 delivers hydraulic oil to the hydraulic cylinder under test to provide hydraulic pressure for the hydraulic cylinder 400 under test. The piston rod of the hydraulic cylinder 400 under test is in contact with the detection end of the measurement and control device 200. When the hydraulic cylinder 400 under test expands and contracts under the pressure of the hydraulic oil, it will exert a thrust or pull on the measurement and control device 200, thereby detecting the hydraulic cylinder under test at this time. 400 generated thrust.

[0039] Such as figure 1 As shown, the oil supply device 100 includes an oil storage tank 101 for oil storage, a single-acting piston cylinder 102 and a driving structure 103 for driving the single-act...

Abstract

The invention discloses a detection system with the effect of overcoming the temperature rise of hydraulic oil in the hydraulic detecting process, and belongs to the technical field of hydraulic detecting equipment. According to the key points of the technical scheme, the detection system comprises a mounting rack used for installing a detected hydraulic cylinder, an oil supply device used for providing hydraulic pressure to the detected hydraulic cylinder, and a detection control device used for detecting the output pressure of the hydraulic cylinder; the oil supply device comprises a single-action piston cylinder and a driving structure used for driving the piston cylinder to extend and retract; a cavity without a piston rod of the single-action piston cylinder communicates with an oil inlet of a cylinder block of the detected hydraulic cylinder, and the cavity without the piston rod of the single-action piston cylinder is full of the hydraulic oil; the mounting rack is fixedly connected with the cylinder block of the detected hydraulic cylinder, and the detection end of the detection control device abuts on the end face of the piston rod of the detected hydraulic cylinder. The detection system has the effect of reducing the temperature rise of the hydraulic oil so that the detection accuracy is improved.

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...
