Damper valve-closing performance testing platform and testing method thereof

Abstract

The invention discloses a damper valve-closing performance testing platform which comprises a base, a servo motor, a speed reduction box, a roller lead screw, a damper test oil tank, an electric control platform and an oil filter working station, wherein the servo motor, the speed reduction box, the roller lead screw and the damper test oil tank are sequentially arranged on the base; the electric control platform and the oil filter working station are arranged on one side of the base. The invention also discloses a testing method of the damper valve-closing performance testing platform. Because an integrated structure is adopted, the mechanical strength is greatly enhanced, the deformation resistance capacity is improved, and meanwhile, installation precision of all assemblies in aspect of height positions and horizontal positions is conveniently regulated. Meanwhile, by combining a real-time closed-ring PLC (Programmable Logic Controller) electrical control system, constant acceleration real-time following control and data acquisition instantaneity are achieved.

Description

technical field [0001] The invention relates to a damper valve detection technology, in particular to a damper valve closing performance test bench and a test method thereof. Background technique [0002] With the rapid development of my country's nuclear power industry, higher requirements are put forward for the operation safety and earthquake resistance of nuclear power plants. Due to the frequent occurrence of earthquakes and natural disasters, hydraulic damper valves are installed in nuclear power plants to resist and absorb the instantaneous impact energy generated by accidents such as earthquakes and pipeline ruptures, and play an anti-seismic support role. In order to ensure the reliability of the hydraulic damper’s operating performance, it is necessary to test the locking performance of the hydraulic damper valve and replace the accessories (generally, the in-service testing period is 10 years).
