膜式电动吸引器与早期的滑片式电动吸引器相比，最显著的优点是噪音低和吸力稳定。但因其结构和电路相对复杂一些，故其故障率以及维修的困难程序也都相应地要高一些。下面将对本人在维修膜式电动吸引器的工作过程中经常遇到的故障、产生的原因以及排除的方法作一初浅的分析介? The most significant advantages of the membrane type electric aspirator compared to the earlier sliding type electric aspirator are low noise and stable suction. However, due to its relatively complex structure and circuit, its failure rate and difficult maintenance procedures are correspondingly higher. A brief analysis of the faults, causes, and exclusions that I often encounter in the course of repairing the membrane type electric aspirator will be given below.
