Description

technical field [0001] The invention relates to a novel high-speed electromagnetic valve, in particular to a high-speed electromagnetic valve for a large reciprocating compressor capable of realizing fast response and an assembly method thereof. Background technique [0002] Reciprocating compressor is a positive displacement compressor widely used in oil refining and chemical industry because of its high discharge pressure and good stability. The rated displacement of the compressor is basically unchanged, but due to changes in the process flow, raw material types and market demand, the displacement of the compressor is required to be adjusted within a wide range. At present, the bypass adjustment method is widely used in China. This method has the advantages of simple structure, continuous change of flow rate, and constant pressure ratio of each level, but it will lose all the compression work of excess gas, and the return gas is compressed. The final high-temperature gas...

AI Technical Summary

Problems solved by technology

The external leakage of the product depends on extrusion and welding after applying sealant, the sealing performance is not ideal, and external leakage is easy to occur under high pressure, posing safety hazards

[0007] d) Since the traditional high-speed solenoid valve has no cooling design, and its compact structure leads to poor heat dissipation, the high temperature generated by the coil after long-term power-on will damage the internal injection molding material, resulting in product failure and low reliability

[0008] e) From the perspective of the structure of the traditional high-speed solenoid valve, although it is small in size, simple in structure, and low in cost, after the product is assembled, all components except the coil cannot be disassembled, and it is not easy to maintain. If there is any problem with the internal parts of the product, the product Failure, resulting in generally low service life

[0009] f) Traditional high-speed solenoid valves and connected electronic control devices are usually independent modules, which cannot realize real-time monitoring functions, and have disadvantages in the integration of electromechanical and hydraulic systems

[0010] The above-mentioned defects of the high-speed solenoid valve can no longer meet the development needs of the reciprocating compressor air volume stepless adjustment system.
