Abstract

The invention discloses a contact high-speed mechanical seal testing device which comprises a bench, a main test chamber, a high-speed torque gauge coupler, a drive motorized spindle, and a cooling and lubricating liquid supply system, wherein the main test chamber, the high-speed torque gauge coupler and the drive motorized spindle are mounted on the bench; the cooling and lubricating liquid supply system is mounted in the bench; the main test chamber and the drive motorized spindle are connected through the high-speed torque gauge coupler; and the drive motorized spindle is connected with the cooling and lubricating liquid supply system. The contact high-speed mechanical seal testing device can perform rotational speed and pressure tests within a greater range, tests performance of mechanical seal at a superspeed, increases mechanical seal test difficulty, and shortens cycles of tests and research and development.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a contact-type high-speed mechanical seal test device. Background technique [0002] The end face of the mechanical seal that acts as a seal is widely accepted due to its extremely low leakage rate, high reliability, long service life, low power consumption, no oil pollution in the process circuit, light weight, small footprint, and low operation and maintenance costs during operation. For the sealing of liquid media, in some places, not only the high-speed rotation of the main shaft is required, but also the leakage of pressurized liquid is required to be controlled. According to the data, more than 86% of the pumps in petrochemical process units use mechanical seals. With the development of mechanical seal technology, the trend of its development in the direction of high parameters has become increasingly prominent, and mechanical seals will occupy a more important pos...
