Problems solved by technology

[0003] The invention provides a hydrostatic test method and device for a super-heavy and super-large compressor casing, which solves or partially solves the problem of using a conventional method in the prior art to carry out a hydrostatic test, and the weak position of the casing will bear extremely high pressure, causing The entire casing product is deformed, resulting in the failure of the hydraulic test. The deformation of the casing is difficult to repair, and it will cause technical problems of scrapping.

Embodiment Construction

[0016] see Figure 1-2 , the embodiment of the present invention provides a hydraulic test method for an overweight and super-large compressor casing. The centrifugal section of the air separation compressor includes a first casing 1 and a second casing. The test method includes the following steps :

[0017] Step 1, setting a support mechanism according to the size of the legs of the first casing 1, and the support mechanism props up the first casing 1;

[0018] Step 2, turning over the first casing 1 so that the middle part of the first casing faces upward, and the support mechanism supports the first casing 1;

[0019] Step 3, installing a pressure testing mechanism in the first casing 1, the pressure testing mechanism divides the first casing 1 into a low-pressure chamber 5 and a high-pressure chamber 6, and the weak position of the first casing is at The low-pressure chamber 5;

[0020] Step 4, filling the low-pressure chamber 5 and the high-pressure chamber 6 of the f...

Abstract

The invention discloses a water pressure testing method and a device of a ultraheavy and ultralarge compressor shell, and belongs to the technical field of space division. The water pressure testing device of the ultraheavy and ultralarge compressor shell comprises a support mechanism contacted with a first shell, a pressure testing mechanism arranged in the first shell, a cavity separation tool flange for dividing the first shell into a low-pressure cavity and a high-pressure cavity, a thin position of the first shell located in the low-pressure cavity, a water passing mechanism connected with the first shell, and a water feeding mechanism communicated with the low-pressure cavity and the high-pressure cavity through the water passing mechanism. The water pressure testing method and the device of the ultraheavy and ultralarge compressor shell reduce the shell deformation risk, smoothly once finish the water pressure test, and save the cost, the time and the labors.

Description

technical field [0001] The invention relates to the technical field of air separation, in particular to a hydraulic test method and device for an overweight and oversized compressor casing. Background technique [0002] For the axial flow plus centrifugal hybrid large-scale air separation compressor unit, the centrifugal section of the air compressor casing needs to be tested by hydraulic pressure. Different from conventional horizontally split centrifugal compressor casings, since its intake side is the exhaust casing of traditional axial flow compressors, there is no bearing area and sealing area on one side, and it is in the form of a large-diameter opening. The pressure on one side is also quite different from the pressure on the next few stages. In addition, the structure of the casing is a thin-walled structure, which requires extremely high machining accuracy and is prone to deformation. It is very risky to carry out hydrostatic testing in a conventional manner. Co...
