Problems solved by technology

Therefore, in addition to the aging of the shaft seal of the propeller shaft, the wear of the shaft seal caused by the rotation of the propeller is very complicated.
At the same time, the shaft seal works underwater, the huge water pressure and the complex wear environment make it impossible to accurately calculate the wear of the shaft seal theoretically

Abstract

The present invention discloses a detection device of a shaft seal test. The detection device comprises a test cavity in which a cavity is arranged and of which one end is opened, a seal tooling arranged at the opening end of the test cavity, a false shaft arranged in the test cavity horizontally and rotatably, a detection element arranged on the test cavity to detect the pressure in the cavity and a container arranged below the test cavity and used for water storage. The test cavity is equipped with a water inlet and a water outlet, a to-be-detected shaft seal member is arranged between the seal tooling and the false shaft, and the false shaft penetrates through the shaft seal member. According to the present invention, the test cavity simulates the rotation and friction between the falseshaft and the shaft seal on different underwater water pressure working conditions, so that the wear situation of the shaft seal under the water can be simulated to a greater extent.

Description

technical field [0001] The invention relates to the field of detection equipment for marine shaft seals, in particular to a detection device for shaft seal tests. Background technique [0002] Shaft seal is an important part of marine equipment. The seal of the propeller shaft is particularly important. The aging and wear of the shaft seal will eventually cause oil leakage in the gearbox or external water into the gearbox, which will affect the transmission in the gearbox. Gear damage is very large. [0003] When the propeller shaft is working, the propeller shaft will eventually bring a huge thrust to the hull, so in addition to its own rotation, the propeller shaft will inevitably move along its axial direction within a certain range. Therefore, in addition to the aging of the material of the shaft seal of the propeller shaft, the wear of the shaft seal caused by the rotation of the propeller is very complicated. At the same time, the shaft seal works underwater, the hug...
