电热型高压蒸汽消毒器电热管的烧坏,大都是因为控制电路失灵或水位过低,电热管不能浸在水中而继续加热所致。为了防止这类故障发生,保证消毒器正常工作,应做到下列几点:1.经常定期检修低水位断电控制电路,保证消毒器能正常运行。2.要保证蒸汽发生器与水位表连接管的畅通,防止水垢堵塞管道。3.适当提高断电水位,也是一项防止电热管烧坏的辅助措施。办法是将原来的导电柱尖端去掉5～10mm。这是由于电热管长期加热,会发生形变凸起或翘端部超出原来的最低水位。
The electric-heated high-pressure steam sterilizer heaters are mostly burned because the control circuit is malfunctioning or the water level is too low. The electric heating tube cannot be immersed in water and heating continues. In order to prevent such failures and ensure the normal operation of the sterilizer, the following points should be done: 1. Regularly check and repair the low-level power-off control circuit to ensure that the sterilizer can operate normally. 2. To ensure the smooth flow of the steam generator and water level meter connecting pipe to prevent scale blocking the pipe. 3. Properly increasing the water cutoff level is also an auxiliary measure to prevent burnout of electric heating pipes. The method is to remove the tip of the original conductive column 5 ~ 10mm. This is due to the long-term heating of the electric heating tube, which will cause deformation or protrusion beyond the original minimum water level.
