A kind of experimental device and experimental method for rotary dynamic sealing characteristics of sealing ring

Abstract

The invention discloses an experimental device and an experimental method for the rotation dynamic sealing characteristics of a sealing ring. The device comprises a support. A torque rotation speed sensor is installed on the support and a sleeve assembly is sleeved on a shaft thereof. The sleeve assembly is fixedly connected with the support. Two Glyd ring mounting parts are arranged in the sleeve assembly at intervals in the axial direction. A sealing ring mounting part is provided between the two Glyd ring mounting parts. After a Glyd ring and a sealing ring are loaded into the Glyd ring mounting parts and the sealing ring mounting part, the shaft can pass through the Glyd ring and the sealing ring to rotate in the Glyd ring and the sealing ring. A containing cavity for the shaft to pass through is arranged inside each of the Glyd ring mounting parts and the sealing ring mounting part respectively inside the sleeve assembly. According to the experimental device for the rotation dynamic sealing characteristics of the sealing ring, a motor driving shaft is rotated inside the sleeve assembly. After a sealing ring is arranged inside a sealing ring mounting part B, the shaft can pass through the sealing ring to rotate in the sealing ring. In this way, the working state of the sealing ring during rotating can be simulated, so that the experiment on the rotation dynamic sealing characteristics of the sealing ring can be conducted.

Description

technical field [0001] The invention belongs to the field of experimental testing devices, in particular to an experimental device and an experimental method for the rotating and dynamic sealing characteristics of a sealing ring in the field. Background technique [0002] The rotational dynamic friction characteristics of the seal ring depend not only on the nature of the seal ring itself, but also on the size and working conditions of its installation groove. Therefore, it is very important to ensure the experimental conditions when studying the rotational dynamic friction characteristics of the sealing ring. The rotating dynamic friction test device of the sealing ring must ensure the groove size, rotation speed, pressure, and the medium of the friction pair. However, most of the existing experimental devices (including tribometers and end-face friction devices) cannot meet the above-mentioned requirements for the rotating dynamic friction experiment of the sealing ring. ...

AI Technical Summary

Problems solved by technology

However, most of the existing experimental devices (including tribometers and end-face friction devices) cannot meet the above-mentioned requirements for the rotating dynamic friction experiment of the sealing ring.

[0003] If the experiment is carried out on the actual machine or on the model, it cannot be widely used for in-depth research on the rotating dynamic friction characteristics of the sealing ring under various working conditions due to the large error.

[0004] In addition, the experimental device for the friction characteristics of rotating dynamic seals in the prior art can only measure the rotating dynamic friction characteristics when the sealing ring is under pressure at one end, and cannot measure the pressure at both ends of the sealing ring (same high pressure, same low pressure, one end low pressure and one end high pressure ) Rotational kinetic friction characteristics
