Abstract

The invention discloses a magnetic liquid sealing pressure-bearing mechanism experimental research device. The device is suitable for the research experiment on the magnetic liquid sealing pressure-bearing mechanism and solves the problems that the end face of an existing magnetic liquid sealing pressure-bearing mechanism experimental research device is difficult to seal, and the experiment is low in reliability. The device comprises a shell (1), a rotating shaft (2), a left bearing (3), a left magnetism separation ring (4), a left pole shoe (5), a permanent magnet (6), a right pole shoe (7), a right magnetism separation ring (8), a right bearing (9), a snap spring (10), an end cover (11), a right sealing ring (12) and a left sealing ring (13). The outer cylindrical surface of the left pole shoe (5) and the outer cylindrical surface of the right pole shoe (7) are respectively provided with pole teeth and tooth sockets. Five stepped holes are formed in the shell which is connected with a pressure gauge. The right end face of the shell is connected with a sealing cavity which has the press capacity, and magnetic liquid sealing pressure-bearing mechanism experimental research is conducted through the change of reading numbers of the pressure gauge.

Description

technical field

[0001] The invention relates to an experimental device for exploring the pressure transmission process of magnetic liquid seals, which is suitable for research experiments on the pressure resistance mechanism of magnetic liquid seals. Background technique

[0002] Magnetic liquid seal has been more and more widely used because of its zero leakage, long life, high reliability and other advantages. However, in the magnetic liquid seal, the problem of how the pressure is transmitted between the magnetic liquid sealing films under each pole tooth has not been fundamentally resolved. Many scientific researchers and engineers who have been engaged in the sealing industry for many years still have very limited understanding of this issue. In the research on this problem, the research device for the sealing and pressure resistance mechanism proposed by the patent No. CN201110098782.3 has the disadvantages of low sealing reliability of the front face of the device. ...
