Abstract

The invention provides a reciprocating sealed foundation test system and method. A piston rod of a first test cylinder and a piston rod of a second test cylinder in the reciprocating sealed foundationtest system are connected with a piston rod of a driving cylinder; an input end of a first main pump is connected with a first oil tank, an output end of the first main pump communicates with a portP of a first electromagnetic reversing valve, a port A of the first electromagnetic reversing valve communicates with an oil inlet of the driving cylinder through a first test branch circuit, an oil outlet of the driving cylinder communicates with a port B of the first electromagnetic reversing valve through a second test branch circuit, and a port T of the first electromagnetic reversing valve isconnected with a first oil tank; and an input end of a second main pump is connected with a second oil tank, an oil inlet of the first test cylinder and an oil inlet of the second test cylinder communicate with an output end of the second main pump, an oil outlet of the first test cylinder and an oil outlet of the second test cylinder are connected with an input end of a first overflow valve, andthe output end of the first overflow valve is connected with the second oil tank. By the system, a frictional force curve, a kinetic friction force curve and a leakage-cycle index curve can be obtained.

Description

technical field [0001] The invention relates to the technical field of sealing element testing, in particular to a reciprocating sealing basic testing system and testing method. Background technique [0002] The hydraulic reciprocating motion seal performance test bench mainly uses a specially designed test system to control the pressure load of a specific change cycle, high oil temperature environment, and high and low speed reciprocating motion on the tested seal, and simulate the performance of the seal. The actual working conditions are tested, and the friction characteristics, wear, leakage and other key performance indicators are measured and recorded during the test process. The test results provide a scientific basis for the comprehensive performance evaluation and application selection of seals. [0003] The existing test system lacks the control of key variables affecting the installation and operation of the reciprocating seal, and the experimental results of the...
