Pump ring used for mechanical seal

Abstract

The invention discloses a pump ring used for a mechanical seal, which comprises a screw-type pump; and a labyrinth seal is connected to one side of the screw-type pump. The pump ring has the advantages that the pumping capacity of the pump ring is improved, and the circulation of fluid on a seal end surface is accelerated, so that the effect of heat exchange and cooling of the seal end surface can be achieved, the temperature of fluid at the seal end surface is reduced, and the service life of the mechanical seal is prolonged.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a pump effect ring for mechanical seals. Background technique [0002] The pump effect ring refers to the device that is set on the outer circle of the sealing rotating part and relies on the pump effect generated when it rotates to make the sealing fluid circulate. [0003] In the prior art, the pumping capacity of the pump efficiency ring is low, the fluid circulation at the sealing end faces is poor, the heat generated by the mutual friction of the sealing end faces is high, the fluid temperature at the sealing end faces is high, and the service life of the mechanical seal is short. Contents of the invention [0004] The object of the present invention is to overcome the above disadvantages and provide a pump effect ring for mechanical seal. [0005] The technical solution adopted by the present invention to achieve the above object is: a pump effect ring for mecha...
