Problems solved by technology

This operation control method will cause impact on the compression pump and affect the service life of the compression pump. In order to increase the start-stop interval of the compression pump, it is necessary to configure a large-capacity air storage tank to increase the volume of the medical air compressor. The start and stop of the compressor pump will also cause noise impact

Abstract

A medical air compressor having adjustable output pressure and operating continuously comprises a medical oil-free compression pump, a high-pressure switch, a low-pressure switch, a relay and an electromagnetic valve, wherein the high-pressure switch and the low-pressure switch are connected with an air outlet of the medical oil-free compression pump respectively; a receiving end of the relay is connected with the high-pressure switch and the low-pressure switch; an output end of the relay is connected with the electromagnetic valve; and the electromagnetic valve is connected with the air outlet of the medical oil-free compression pump. The medical air compressor can be adjusted in output pressure range and operate continuously in any adjustment pressure range, thereby having a smaller size, lower noise and a longer service life.

Description

technical field [0001] The invention relates to the field of operation control of medical air compressors, in particular to a medical air compressor with adjustable output pressure and continuous operation. Background technique [0002] There are two main operation control methods for existing medical air compressors: [0003] 1) The use of variable frequency compressor pumps to maintain the outlet pressure of medical air compressors and continue to run. Basically, only imported brand medical air compressors adopt this operation control method, and there is no suitable manufacturer of variable frequency compressor pumps in China. When the medical air compressor is working, the outlet pressure is maintained by increasing or decreasing the minute revolutions of the variable frequency compressor pump and the compressor pump continues to run. This operation control method is expensive and complicated, and there is no supporting supplier in China. [0004] 2) Use a range-type p...
