Problems solved by technology

[0003] At present, the research on the fault principle and experimental simulation of reciprocating compressors is mainly focused on the reciprocating compressors on the solid foundation, while the research on the reciprocating compressors working on the offshore oil production platform is less; therefore, it is necessary to build a reciprocating compressor that can effectively simulate the offshore oil production platform. It is particularly necessary to study the common faults of reciprocating compressors working on this base, and there is no such experimental platform at home and abroad.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0022] The implementation process of the present invention is mainly composed of 4 major parts, and the detailed steps are as follows.

[0023] (1) Survey and map the overall dimensions of the reciprocating compressor, including length, width, height, and the dimensions of the external structure of the parts that need to be matched with the test bench, to determine the force and load of the test bench;

[0024] The reciprocating compressor used is a DW-12 / 2 type non-lubricated air compressor. The total length of the body is 4208mm, the total width is 2292mm, the total height is 2300mm, and the weight is about 5t (including the motor). Figure 5 shown.

[0025] (2) Determine the overall shape and size of the test bench;

[0026] The design base has an overall length of 4490mm, a width of 2550mm, and a height of 873.5mm. A T-like shape structure is selecte...

Abstract

The invention relates to a floating type reciprocating compressor fault simulation test bench, wherein a main body structure of the floating type reciprocating compressor fault simulation test bench comprises an upper layer frame, a lower layer frame, a flexible support and a rigid support, the upper layer frame is used to fix a reciprocating compressor and a driver, the lower frame is directly fixed on the ground, or is fixed on an offshore production platform steel frame, a test bench support structure is formed by adopting a mode that the flexible support and a rigid stand column support are combined, the flexible support selects a spring or a hydraulic system, the rigid support uses a stand column support, stand columns use positive and negative screw thread structures, the height of the stand columns can be adjusted, and the stress state of the flexible support can be changed to achieve change of test bench support stiffness. The stand column support uses a self-lock structure, and the flexible support is provided with a guide column. The floating type reciprocating compressor fault simulation test bench can be used for the reciprocating compressor, further can be used for design, processing and installation of other large key mobile equipment on an offshore platform, and is used to solve the different problems of fault diagnosis and the design of supporting structures of offshore platform large mobile equipment.

Description

technical field [0001] The invention relates to a floating reciprocating compressor fault simulation experiment platform, which is used for simulating the working environment of the reciprocating compressor on an ocean platform, and conducting research on the fault simulation experiment of the reciprocating compressor. Background technique [0002] Under the action of ocean waves, currents and wind loads, the offshore oil production platform will have a dynamic response, and the reciprocating compressors, pumps and other equipment working on the platform will therefore be on a floating base, fixed on a solid foundation with land refining and chemical enterprises There is a significant difference between the above units; this change in working status will cause different failures of the reciprocating compressor, such as unbalance, misalignment, loose foundation, etc. [0003] At present, the research on the fault principle and experimental simulation of reciprocating compress...
