電動礦用排汙泵潛水泵爆炸主要與（yǔ）電機進水與電機過載發（fā）熱有關，終（zhōng）與水在被加熱的過程中，液態水變為氣態水蒸（zhēng）氣後的熱力（lì）學特性有關，即與（yǔ）水蒸汽的溫度（dù）與壓力有關。若電機外殼隻有密封裝置，沒（méi）有泄壓裝置，這（zhè）就如（rú）同沒有安全閥的鍋（guō）爐有（yǒu）爆炸隱患，一旦爆（bào）炸，就是（shì）蒸汽爆炸。
The explosion of submersible pump of electric mine sewage pump is mainly related to the water intake of motor and the overload heating of motor, and ultimately to the thermodynamic characteristics of water when it is heated, that is, to the temperature and pressure of water vapor. If the motor shell only has a sealing device and no pressure relief device, it is like a boiler without a safety valve has a potential explosion hazard. Once it explodes, it is a steam explosion.
具有過熱保護、過載保護：比如意外情況可能導致泵電機溫度異常升高，微此時水泵會自動保（bǎo）護（hù）停機，避免電機燒毀;若有異物落（luò）入電機，可能會卡死，水泵也會（huì）自（zì）動保護停機，避免電機燒毀;所以新為誠微型水泵WNY係（xì）列的自（zì）我保護功能堪稱優秀。
With overheat protection and overload protection: for example, accidents may lead to abnormal temperature rise of pump motor, micro-pump will automatically protect the shutdown to avoid motor burning; if foreign body falls into the motor, it may jam, pump will automatically protect the shutdown to avoid motor burning; so the self-protection function of WNY series of new Weicheng micro-pump is perfect.
煤礦用（yòng）潛水泵配備了電動機，然後強行排沙就會功率（lǜ）不足;同時電動（dòng）機又缺（quē）少排沙必備的“泄壓安全（quán）閥”，在這種條件下，潛水泵爆炸的主要根源很可能是因為其電動機外殼本身就是“密封容器”，“水源”是排沙振動導致的電動機內腔進水，“熱源”是排沙過載導（dǎo）致的（de）電動機（jī）內腔異常發熱。
Submersible pumps used in coal mines are equipped with motors, and then forced sediment discharge will result in insufficient power; at the same time, the motors lack the necessary "relief safety valve" for sediment discharge. Under such conditions, the main cause of the explosion of submersible pumps is probably that the motor shell itself is a "sealed container", "water source" is the water intake of the motor chamber caused by the vibration of sediment discharge, and "heat source" is the overload conductivity of sediment discharge. Causes abnormal fever in the motor chamber.
