Description
技术领域 technical field

背景技术 Background technique
隔膜式压缩机是一种特殊结构的容积式压缩机，具有压缩比大、密封性好、压缩气体不受润滑油和其它固体杂质所污染的特点。一般地，隔膜压缩机主要由驱动机构、气缸部件、润滑油系统、气管路部件、曲轴箱部件等组成。根据隔膜式压缩机的工作原理，其流量的大小主要由隔膜压缩机的气缸的大小及进气压力所决定的，通常，隔膜压缩机的使用者，总是根据最大的耗气量来选用隔膜压缩机。然而在实际生产中，由于种种原因，用户要求改变隔膜压缩机的流量，以适用实际的生产需要，例如：（1）由于流程和工艺上的原因要求减少供气量；（2）由于其他设备、机器及工具特性的改变，也要求隔膜压缩机的排气量作频繁的调整。 Diaphragm compressor is a volumetric compressor with a special structure, which has the characteristics of large compression ratio, good sealing performance, and the compressed gas is not polluted by lubricating oil and other solid impurities. Generally, a diaphragm compressor is mainly composed of a driving mechanism, cylinder components, lubricating oil system, gas pipeline components, crankcase components, etc. According to the working principle of the diaphragm compressor, the flow rate is mainly determined by the size of the cylinder of the diaphragm compressor and the intake pressure. Usually, the user of the diaphragm compressor always chooses the diaphragm compressor according to the maximum air consumption. machine. However, in actual production, due to various reasons, the user requires to change the flow rate of the diaphragm compressor to meet the actual production needs, for example: (1) due to process and process reasons, the air supply volume is required to be reduced; (2) due to other equipment , The change of the characteristics of the machine and the tool also requires frequent adjustment of the displacement of the diaphragm compressor.
从压缩机的作用原理得知，隔膜压缩机也属于容积式压缩机的范畴，容积式压缩机的流量不会由于背压的升高而自动降低，如不进行有效的调节，在有些场合甚至会出现危险事故，若原压缩机继续使用，必须更换适用用户更改流量参数的压缩机，这样会大大增加用户的使用成本。 From the working principle of the compressor, it is known that the diaphragm compressor also belongs to the category of the positive displacement compressor. The flow rate of the positive displacement compressor will not automatically decrease due to the increase of the back pressure. Dangerous accidents will occur. If the original compressor continues to be used, it must be replaced with a compressor suitable for the user to change the flow parameters, which will greatly increase the user's use cost.
