Embodiment Construction

[0024] Such as figure 1 The shown dual feedback control system of the air compressor unit includes a small compressor unit providing low-pressure air and its low-pressure pipeline to low-pressure air users, and a large compressor unit providing high-pressure air and its high-pressure pipeline to high-pressure air users. There is an intercommunication pipeline between the low-pressure pipeline and the high-pressure pipeline, and there is a flow distribution valve on the intercommunication pipeline to control its on-off.

[0025] There is a low-pressure flow meter and a low-pressure pressure gauge on the low-pressure pipeline between the communication pipeline and the low-pressure gas user, and a high-pressure pressure gauge on the high-pressure pipeline between the communication pipeline and the high-pressure gas user.

[0026] There are also a flow controller and a pressure controller. The flow controller is connected to the low-pressure flowmeter through the flow signal line ...

Abstract

The invention discloses an air compressor set double feedback control system. The air compressor set double feedback control system comprises a small compressor set body used for providing low-pressure air, a low-pressure pipeline, led to low-pressure air users, of the small compressor set body, a large compressor set body used for providing high-pressure air, and a high-pressure pipeline body, led to high-pressure air users, of the large compressor set body. An interflow pipeline and a flow distributing valve controlling the interflow pipeline to be connected or disconnected are arranged between the low-pressure pipeline and the high-pressure pipeline. The low-pressure pipeline is provided with a low-pressure flowmeter and a low-pressure pressure meter. The high-pressure pipeline is provided with a high-pressure pressure meter. The control system further comprises a flow controller and a pressure controller. According to the control method of the control system, the combinational control function is achieved through a linkage induction control circuit between the flow controller and the pressure controller. Linkage control is adopted, the system does not need to be watched by many persons and can provide different compressed airs for the users for use, the air supply efficiency is high, and the power consumption is low.

Description

technical field [0001] The present invention relates to the production and distribution technology of compressed air. Background technique [0002] The working principle of the air compressor: After the drive motor is started, the crankshaft of the compressor is driven to rotate by the conveyor belt, which is converted into a reciprocating motion of the piston in the cylinder through the crank rod mechanism. The outside air enters the cylinder through the filter and the suction valve, the air in the cylinder is compressed and the pressure increases, and the compressed air enters the air storage tank through the pipeline to obtain the required compressed air. [0003] The invention with the patent application number 201310661533X provides an air pressure control method and system for a drilling rig air compressor. The air pressure of the drilling rig air compressor has a working pressure state and an unloading state, and the air pressure in the working pressure state is great...
