Problems solved by technology

Especially in the maintenance service after the casing leaves the factory, the conditions for carrying out the hydraulic test of the casing become extremely inconvenient
If any one or more of the pipelines of the casing is damaged after leaving the factory, the whole machine needs to participate in the hydraulic test again, which has caused great trouble to the on-site service. The site of the equipment and test conditions, and even return to the factory for the hydraulic test of the casing
The overall pressure test will also involve a series of cumbersome work, for example: the rotor and partition related parts must be disassembled and hoisted from the casing, and the corresponding safe site protection must be found, and the upper and lower casings must be It is disassembled from the on-site platform, and a heavy-duty trailer needs to be arranged to transfer the upper and lower casings to the location where the hydraulic test of the casing is carried out, and then the hydraulic test of the casing is carried out according to the relevant process flow in the factory. The work intensity is very heavy and cumbersome. , and unnecessary costs will be incurred, and the installation cycle of the entire project using horizontally split centrifugal compressors will be severely hindered

Embodiment 1

[0039] In order to solve the problems of cumbersome and complicated pressure test operation in the production process and post-maintenance of the horizontally split centrifugal compressor casing in the prior art, which cost a lot of money and are limited by the site, this embodiment combines the attached figure 1 - attached Figure 6 Provided is a horizontal split centrifugal compressor casing pressure bearing test device, which is used for single piece hydraulic pressure test of the horizontal split centrifugal compressor casing pipeline. The above-mentioned horizontally split centrifugal compressor shell pressure test device includes: a pressurizing mechanism, which is connected to the internal seal of one end of the single piece of pipeline, and is used to inject water and pressurize the single piece of pipeline; Go deep into the other end of the pipeline single piece, used to seal the other end of the pipeline single piece; the support mechanism is provided with a limit st...

Embodiment 2

[0052] This embodiment provides a horizontal split centrifugal compressor casing pressure test method, which is realized by using the horizontal split centrifugal compressor casing pressure test device involved in any preferred technical solution in embodiment 1, The method includes the following steps: hoisting and placing the upper casing of the horizontally split centrifugal compressor on a horizontal plane; selecting a single piece of pipeline for a pressure test; end; the fixed support mechanism withstands the blocking mechanism 2; the first valve 15 and the second valve 16 are adjusted cooperatively so that the pressure in the single piece of the pipeline reaches a preset pressure value. In order to insert the blocking mechanism 2 into the single piece of pipeline conveniently and smoothly, a chamfer is provided at the connecting end of the blocking mechanism 2 with the single piece of pipeline. Since the medium used in the pressure test of the casing of the horizontal s...

Abstract

The invention discloses a pressure-bearing test device for a casing of a horizontal split centrifugal compressor, which relates to the technical field of structural design of a turbomachinery detection device, and is used for a single-piece hydraulic test of a casing pipeline of a horizontal split centrifugal compressor, including: The pressurizing mechanism is in sealing communication with one end of the pipeline unit, which is used to inject water and pressurize the pipeline unit; the sealing mechanism, one end goes deep into the other end of the pipeline unit, and is used to seal the pipeline unit The other end: the supporting mechanism is provided with a limiting structure, which is used to support the blocking mechanism to keep blocking the single piece of the pipeline, and the other end of the blocking mechanism is against the limiting structure. The invention avoids transporting the horizontally split centrifugal compressor to a designated place for complete machine testing, and can be operated at the construction site of the centrifugal compressor, greatly reducing the transportation cost and time of the casing pressure test of the horizontally split centrifugal compressor cost. The method of the invention is flexible, simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of structural design of a turbomachinery detection device, in particular to a pressure-bearing test device and method for a casing of a horizontal split centrifugal compressor. Background technique [0002] As we all know, the main components of a horizontally split centrifugal compressor are the stator and the rotor, and the casing in the stator is the main load-bearing part of the entire horizontally split centrifugal compressor for pressure bearing, high temperature resistance, and flow diversion. The quality of the casing determines whether the entire horizontal split compressor can run normally and smoothly. [0003] The manufacturing process of the casing is cumbersome and complicated, and there are many technical difficulties in the processing process. Among the many technical difficulties, the pressure-bearing requirements of the casing are the most stringent in the entire casing processing process,...
