Energy-saving transformation method for high-pressure 4M32G-186 carbon dioxide compressor

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...

Problems solved by technology

However, the field practice shows that the existing high-pressure 4M32G-186 carbon dioxide compressor energy-saving transformation method can only achieve the design requirements, but cannot obtain greater energy-saving effects, thus breaking through its original design requirements
