Problems solved by technology

[0002] The inlet and outlet sealing diaphragms for turbo pumps need to be tested for reliability under certain pressure conditions under natural storage conditions. The turbo pump chamber is pressurized, so that the sealed diaphragm is stored naturally under a specific storage pressure state to assess its reliability. This test method requires more equipment, and the number of diaphragms that can be assessed during a single test Also less, the overall test cost is higher

Embodiment Construction

[0034] Specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The present invention generally includes three major parts, that is, a spring pressure accumulator module, a one-way valve filling module, and a sealing device body module.

[0036] The spring accumulator module is mainly used to compress and boost the fluid medium in the test equipment to ensure that the fluid medium in the test equipment is in a controllable pressure range for a long time. The spring accumulator module mainly includes the accumulator seat, the compression spring , Booster piston, thrust bearing, spring seat, adjusting nut, guide rod, lock nut, etc.

[0037] The one-way valve filling module is mainly used for one-way filling and sealing of fluid in the test equipment. The one-way valve filling module can also realize the opening pressure adjustment function. The one-way valve module mainly includes the valve bo...

Abstract

The invention relates to test equipment for a natural storage life test of a sealing diaphragm. The test equipment comprises a spring pressure accumulator module, a one-way valve filling module and a sealing device body module, the spring pressure accumulator module and the one-way valve filling module are connected to the two ends of the sealing device body module respectively; the one-way valve filling module is used for conducting fluid one-way filling and sealing on the sealing device body module; the spring pressure accumulator module is used for compressing and pressurizing a fluid medium in the sealing device body module to ensure that the fluid medium in the sealing device body module is within a controllable pressure range; and the sealing device body module is provided with a tested inlet diaphragm assembly and a tested outlet diaphragm assembly. According to the test equipment, the problem of sealing pressure-resistant reliability of the inlet and outlet sealing membranes matched with the turbine pump under the natural storage condition is solved.

Description

technical field [0001] The invention relates to a diaphragm life test device, in particular to a test device for a natural storage life test of a sealed diaphragm, which is mainly used for evaluating the reliability of the sealed pressure resistance of the sealed diaphragm under natural storage conditions. Background technique [0002] The inlet and outlet sealing diaphragms for turbo pumps need to be tested for reliability under certain pressure conditions under natural storage conditions. The turbo pump chamber is pressurized, so that the sealed diaphragm is stored naturally under a specific storage pressure state to assess its reliability. This test method requires more equipment, and the number of diaphragms that can be assessed during a single test It is also less, and the overall test cost is higher. Contents of the invention [0003] The technical problem of the present invention is: to overcome the deficiencies of the prior art, to provide a test equipment for the...
