Reciprocating oil seal performance testing testbed

Abstract

The invention discloses a reciprocating oil seal performance testing test bench, which includes a motor, a crank connecting rod mechanism, a sliding bearing, an end cover, a cylinder barrel, a valve system, an oil seal, an oil supply chamber and other components, and the output shaft of the motor is connected to the oil filling chamber through a key. The crank is connected with the mechanism, and the crank-link mechanism is connected with the piston rod through internal and external threads to drive the piston rod to move; there is an oil leakage hole at the bottom of the cylinder where the oil seal is installed, and a small beaker is placed under the oil leakage hole to catch the leakage, and a precision balance is used Weigh out the leakage in different time periods; place a temperature sensor near the seal of the oil seal to record the temperature change of the lip during movement; the right end of the cylinder is connected to the oil supply chamber, which can collect or supplement the reciprocating piston rod Oil in motion. The invention can simulate the pressure change in the sealing chamber of the reciprocating oil seal, measure the leakage and temperature changes of the oil seal under different interference, reciprocating speed, oil internal pressure, friction coefficient, and provide guidance for the production and use of the oil seal.

Description

technical field [0001] The invention relates to a test bench for comprehensive performance testing of oil seals, in particular for testing the performance of reciprocating oil seals. Background technique [0002] With the rapid development of modern industry, especially the development of machinery industry, the use of reciprocating oil seals is becoming more and more extensive. The reciprocating oil seal is a sealing component used to prevent leakage of the reciprocating shaft or piston. Like other seals, the sealing performance of the reciprocating oil seal directly determines the operation of the machine and equipment. Even a small amount of leakage at the seal will affect the sealing effect. If the sealing performance of the reciprocating oil seal is not good, it is very It may reduce the service life of mechanical equipment, pollute the environment, and even pose a threat to personal safety. [0003] At present, most of the performance tests of reciprocating oil seals...
