电动吸引器常见故障多为贮液瓶中废液未能及时清除,进入负压泵,锈蚀泵内部件,旋转困难,使电机因转速不够、离心开关不能及时切断启动绕组电源而烧坏。即便将负压泵拆散清冼,重新装配好,其效果也大为降低。近年来一些厂家根据此类故障原因,在吸引器内设汁安装继电器液位保护器和浮子式液位保护装置。此类装置在使用中常因液面触点锈蚀、氧化,控制失灵。尚若机器电气绝缘性能破坏将会因漏电发生电击伤、亡事故。浮子式液位保护装置会因塑料老化变形,密闭性能差、活动不灵,废液同样可以进入负压泵,造成上述
Common failures of electric suction pump are mostly liquid bottles of liquid waste can not be promptly removed, into the negative pressure pump, corrosion pump parts, rotating difficulties, the motor speed is not enough, the centrifugal switch can not be cut off in time to start the winding power supply and burn out. Even if the negative pressure pump is disassembled and reassembled, the effect is greatly reduced. In recent years, some manufacturers based on such failure reasons, set in the suction device to install the relay liquid level protector and float level protection device. Such devices in use often due to liquid level contact corrosion, oxidation, control failure. Shang Ruo if the electrical insulation properties of the machine will be damaged due to electric shock injury, fatal accident. Float level protection device due to plastic deformation, poor sealing performance, activities are not working, waste can also enter the negative pressure pump, resulting in the above
