Abstract

The invention discloses a compressor flow regulation system based on clearance regulation. The compressor flow regulation system based on clearance regulation is characterized in that a flow regulation device is mounted on a compressor cylinder, an executive motor is used for controlling and regulating the volume change of the cylinder, the size of the clearance volume of the compressor cylinder is changed, the flow of the compressor is regulated, and the power consumption of the compressor under partial load is reduced. According to the executive mode of the system, a monitoring system is arranged according to the requirements of system flow, the monitoring system controls the executive motor to work, the executive motor drives a regulating piston to move, the clearance volume of the compressor cylinder is changed automatically according to control requirements, and the automatic stepless regulation of compressor flow is achieved.

Description

technical field

[0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor flow regulation system based on clearance regulation. Background technique

[0002] Compressor is an important energy-consuming equipment in petroleum, chemical, metallurgy and other industrial fields. The process often requires it to work under partial load and flow adjustment is required.

[0003] There are many ways to adjust the flow rate of reciprocating compressors. One is to use part of the stroke to open the intake valve to adjust the flow rate. For example, in US5833209 and US7331767 patents, hydraulic pressure and gas force are used to press and open the intake valve under part of the stroke. The stepless adjustment of the flow rate of the compressor is realized, but the device has extremely high requirements on the reliability and life of the solenoid valve. Patents CN201232620 and CN101270741 use a hydraulic distributor instead of a solen...

Examples

Embodiment Construction

[0027] see figure 1 , the compressor flow regulation system based on clearance adjustment in this embodiment is to install the flow regulating device 3 on the compressor cylinder 4, and use the monitoring system 11 to drive the actuator motor 7 to control the movement of the regulating piston 304 in the flow regulating device 3, so as to realize The volume change of the regulating cylinder 305 in the flow regulating device 3 is used to control the clearance volume of the compressor cylinder 4 by the volume change of the flow regulating cylinder 305, so as to realize the automatic stepless regulation of the flow of the compressor.

[0028] Setting up a monitoring system includes:

[0029] The suction pressure sensor 1 installed on the compressor suction pipe 2 is used to detect the compressor suction pressure in real time;

[0030] The discharge pressure sensor 6 installed on the compressor discharge pipeline 5 is used to detect the compressor discharge pressure in real time; ...
