Abstract
A submersible pump comprises a shell body, a base arranged on the bottom of the shell body and a water outlet channel. The shell body is a cylinder shape with downward opening on the top of which a power supply joint is arranged and in which a motor is arranged. The motor whose power supply cord connects with the waterproof power supply joint comprises a frame, a rotor, a stator, a bearing and a impeller. The submersible pump is characterized in that: the frame and the bottom of the shell body are fixed and sealed to form a sealed space between the frame and the inside of the shell body, an oil filling hole is arranged on the top of the shell body through which a certain amount of plant oil is injected into the sealed space. The submersible pump has the advantages that: firstly, the plant oil is injected into the shell body which plays a key role in cooling the motor; secondly, the plant oil can make the conductor insulate from the shell which prevents leakage, therefore being safer in using; thirdly, the oil filling hole is arranged on the top of the shell body, so injecting the plant oil into the shell body is more convenient; fourthly, the plant oil has good effect in lubricating in the motor; fifthly, the service life of the motor is increased.
