Embodiment 1

[0084] The high-pressure 4M32G-186 carbon dioxide compressor in the compressor workshop of Jinneng Holding Equipment Manufacturing Group Tianyuan Shanxi Chemical Co., Ltd. was transformed as follows:

[0085] S1. Change the inner diameter of the first-stage cylinder from 1082mm to 1085mm, the inner diameter of the second-stage cylinder from 622mm to 625mm, the inner diameter of the third-stage cylinder from 282mm to 285mm, the inner diameter of the fourth-stage cylinder from 300mm to 303mm, and the inner diameter of the fifth-stage cylinder Internal diameter changed from 148mm to 155mm;

[0086] S2, the piston is changed from a split type to an integral type; and

[0087] Change the outer diameter of the first-stage piston from 1073mm to 1077mm, the outer diameter of the second-stage piston from 615mm to 619mm, the outer diameter of the third-stage piston from 276mm to 279mm, the outer diameter of the fourth-stage piston from 295mm to 297mm, and the outer diameter of the fifth...

Abstract

The invention discloses an energy-saving transformation method for a high-pressure 4M32G-186 carbon dioxide compressor. The method comprises the following steps that the inner diameters of first-stage to fifth-stage cylinder bodies are transformed, first-stage to fifth-stage pistons are changed into an integral type from a split type, the outer diameters and the weight of the first-stage to fifth-stage pistons are changed, first-stage to fifth-stage open air valves are changed into closed air valves, and the outer diameters of the first-stage to fifth-stage air valves, the outer diameters of first-stage to fifth-stage valve blocks and the air channel clearances of the air valves of the first-stage to fifth-stage cylinder bodies are transformed. After transformation, the inflating amount of each compressor can be increased by more than or equal to 30%, the original design requirement of the compressors is broken through, the operating power of the compressors is kept unchanged, and the energy consumption is not increased, so that the yield of enterprises using the compressors is increased, a large amount of energy is saved, and great economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of compressor transformation, and in particular relates to a method for energy-saving transformation of a 146kg high-pressure 4M32G-186 carbon dioxide compressor. Background technique [0002] Large-scale compressors are one of the commonly used equipment in chemical enterprises, and it is difficult to modify them after installation and use. The difficulty and complexity of modification are well known to those skilled in the art. Moreover, for different types of compressors, due to the difference in structure or pressure, the transformation methods cannot be the same, but corresponding transformations must be carried out according to different models. For example, the 6M50 raw gas compressor is a commonly used reciprocating nitrogen and hydrogen compressor (see figure 1 As shown), it is one of the key equipment in my country's chemical enterprises. There are about 100 units in the country, and it must be gu...
