Embodiment 1
[0018] Embodiment 1, basically as attached figure 1 Shown: a cleaning method for the end face seal of a screw compressor. The end face seal of a screw compressor includes a moving ring 1 positioned on a shaft sleeve 8. A static ring assembly is provided on the medium side and the atmospheric side of the moving ring 1. The static ring The assembly includes a static ring 2 and a static ring seat 3, and a spring energy-storage sealing ring 4 is provided between the static ring 2 and the static ring seat 3 on the atmospheric side, such as figure 2 As shown, the spring energy storage sealing ring 4 includes a jacket 41 with a C-shaped cross section, and an energy storage spring 42 with a C-shaped cross section is embedded in the jacket 41 . Four circular flushing holes 7 with a diameter of 3 mm are opened in the circumferential direction of the static ring seat 3 on the medium side. A primary comb seal 9 is provided between the static ring seat 3 and the shaft sleeve 8 on the med...

The invention discloses a cleaning method for end face sealing of a screw compressor in the technical field of screw compressor sealing. The method comprises a moving ring positioned on a shaft sleeve, static ring assemblies are arranged on the medium side and the atmosphere side of the moving ring, each static ring assembly comprises a static ring and a static ring base, a spring energy storage sealing ring is arranged between the static ring on the atmosphere side and the static ring base, the spring energy storage sealing ring comprises a clamping sleeve with a C-shaped section, an energy storage spring with a C-shaped section is embedded in the clamping sleeve, a flushing hole is formed in the static ring base at the medium side of the end face seal of the screw compressor, and cleaning liquid is fed into the end face seal through the flushing hole to clean the medium of a friction pair. The problems that in the prior art, after impurities are attached to the static ring sealing ring in screw compressor end face sealing, a spring is stuck by a medium and loses efficacy, so that the static ring does not have floatability, sealing face attachment is affected, and effective sealing cannot be achieved can be solved.
Description
[0001] This case is a divisional application, and the application number of the parent case is: 202111209314.9; the invention and creation name of the parent case is: a method for cleaning the end face seal of a screw compressor and its cleaning method; the applicant of the parent case is: China Petroleum & Chemical Corporation , Sinopec Chongqing Chuanwei Chemical Co., Ltd.; the filing date of the parent case is: October 18, 2021; the application type of the parent case is: invention patent. technical field [0002] The invention relates to the technical field of screw compressor sealing, in particular to a method for cleaning the end face seal of a screw compressor. Background technique [0003] Screw compressors are widely used in various petrochemical enterprises, and the most important feature is to allow the compressed medium to carry liquid. The shaft end seal of the screw compressor mostly adopts the contact mechanical seal form. In the production process of partial...
