电动矿用排污泵潜水泵爆炸主要与电机进水与电机过载发热有关，终与水在被加热的过程中，液态水变为气态水蒸气后的热力学特性有关，即与水蒸汽的温度与压力有关。若电机外壳只有密封装置，没有泄压装置，这就如同没有安全阀的锅炉有爆炸隐患，一旦爆炸，就是蒸汽爆炸。
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.
具有过热保护、过载保护：比如意外情况可能导致泵电机温度异常升高，微此时水泵会自动保护停机，避免电机烧毁;若有异物落入电机，可能会卡死，水泵也会自动保护停机，避免电机烧毁;所以新为诚微型水泵WNY系列的自我保护功能堪称优秀。
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.
煤矿用潜水泵配备了电动机，然后强行排沙就会功率不足;同时电动机又缺少排沙必备的“泄压安全阀”，在这种条件下，潜水泵爆炸的主要根源很可能是因为其电动机外壳本身就是“密封容器”，“水源”是排沙振动导致的电动机内腔进水，“热源”是排沙过载导致的电动机内腔异常发热。
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.
