Abstract

The invention discloses a submersible pump. The submersible pump comprises a motor cover, a motor shell, an oil tank, a pump body and a base, wherein the motor cover, the motor shell, the oil tank, the pump body and the base are arranged from top to bottom in sequence; a cable and a hanging hook are arranged on the motor cover; a wire connecting plate and a first water leakage detecting probe are arranged in the motor cover; the cable, the wire connecting plate and the first water leakage detecting probe are electrically connected in sequence; a stator, a rotor and a pump shaft are arranged in the motor shell; the stator is electrically connected with the wire connecting plate; the rotor is in transmission connection with the pump shaft; and a bearing, a sealing piece and an impeller are arranged on the pump shaft in sequence. The submersible pump greatly improves the dirt passing capacity, is compact in structure, small in size, low in noise, prominent in energy saving effect and convenient for maintenance, largely reduces the construction cost, and is convenient and reliable in use.

Description

technical field [0001] The invention relates to the technical field of a pump body, in particular to a submersible pump. Background technique [0002] Routine maintenance of submersible pumps. Check whether the power cord is damaged every day, and it is absolutely forbidden to launch the submersible pump with leakage. Check whether the water pump body is damaged every day to ensure that the motor does not leak electricity when it is working. After the operation is over, the sundries attached to the water pump should be cleaned up in time, and the water pump should be rinsed clean. In order to ensure the normal operation of the submersible pump, the following requirements must be followed. Before using the submersible pump, the insulation resistance of the motor must be checked with a megohmmeter, and the minimum value should not be less than 50MΩ. [0003] The water-immersed motor should open the water filling screw plug, fill it with clean water, and then tighten the sc...
