Abstract
A testing platform with a floating cylinder for high-pressure and high-speed reciprocating sealing experiment, characterized in that, includes a frame, a cylinder body for testing and a high-speed driving device, the frame comprises a horizontal rolling guide rail (), the cylinder body for testing comprises a cylinder, the cylinder is floatingly mounted on the rolling guide rail and is mounted to the frame through a tension-compression sensor which is in the same direction as the rolling guide rail, the cylinder is cylindrical as a whole, has a cavity in a middle and openings on two sides with a diameter slightly greater than a diameter of a test rod, the cylinder includes a left end cover affixed on a left side, a right end cover affixed on a right side, a left seal between the left end cover and the cylinder, a right seal between the right end cover and the cylinder, the piston rod penetrates into the cylinder horizontally and passes through the left end cover, the left seal, the right seal and the right end cover, the piston rod has one side connected to the high-speed driving device with a motor. The present invention can provide stable high-pressure and high-speed working conditions, can accurately measure the frictional force of the sealing ring, and provide more extensive experimental conditions and experimental data for the research of reciprocating sealing performance.
