Abstract

The invention discloses a stepless delivery regulation method of reciprocating-piston compressor, which is characterized in that duty cycle is determined using the maximum delivery and the actually required delivery of the compressor under full load; an inhalation valve is forced to open or freely closed through a control system and a or a plurality of executive device (s) for pressing the inhalation valve, enabling load circulation and non-load circulation to be alternatively distributed to comply with the duty cycle, thereby evenly supplying the required delivery. The invention has the advantages of capability of 0 to 100% continuous delivery regulation, less pressure fluctuation, saved energy, lowered noise, simple and reliable regulation effect.

Description

technical field

[0001] The invention relates to a flow regulating method, in particular to a method for regulating the displacement of a reciprocating piston compressor. Background technique

[0002] Reciprocating piston compressors (hereinafter referred to as compressors) are widely used in industry and daily life, and are one of the essential key equipment in various sectors of the national economy, especially in petrochemical and other process industries. The rated discharge capacity of the compressor remains basically unchanged under normal operating conditions. Generally, it is designed or selected according to the maximum flow rate required by the process, and the discharge capacity has a certain margin. On the other hand, in actual use, changes in the working conditions of gas-consuming equipment such as inlet pressure, temperature, and medium composition, changes in production conditions, and changes in market demand often occur, resulting in users' consumption of ga...
