兹将维修一台捷克产牙科综合治疗机Chiranu Made in Czchoslovakia电磁阀跳动故障一例的经验,提供给同行们参考.故障现象:开机后,压力正常,电磁阀跳动不止.故障分析:根据分析,故障可由以下几种情形之一所致:1.电源回路中有接触不良之处,使之在开机后因负载而产电压降,致使电磁阀跳动;2.电磁阀本身有故障;3.控制回路中有接地、短路等故障点,造成电压急剧下降,必然引起电磁阀跳动.
We will repair the experience of a Czech-made dental unit Chiranu Made in Czchoslovakia solenoid valve jumping fault and provide them with reference to colleagues. Symptoms: After starting up, the pressure is normal, and the solenoid valve beats more. Failure analysis: According to the analysis, failure It can be caused by one of the following situations: 1. There is poor contact in the power supply circuit, which causes the voltage drop due to the load after starting up, causing the solenoid valve to jump; 2. The solenoid valve itself has a fault; 3. The control circuit There are ground faults, short-circuit faults, etc., causing a sharp drop in voltage, which inevitably causes the solenoid valve to jump.
