Abstract

The invention provides a frequency conversion device mounting structure of a submersible pump, belonging to the technical field of submersible pumps. According to the invention, the problems that a frequency converter is independently arranged outside the submersible pump body and thus is easily damped and damaged, and potential safety hazard in electricity utilization exists and the like in the prior art are solved. The frequency conversion device mounting structure comprises a frequency conversion motor and a pump component connected to the frequency conversion motor, wherein the frequency conversion motor comprises a motor shell with a motor cavity; a frequency conversion motor component for driving the pump component to work is mounted in the motor cavity; the motor shell is in a sealed structure; a frequency conversion device connected with the frequency conversion motor is also arranged in the motor cavity; the frequency conversion device comprises a printed circuit board fixed in the motor cavity; and the printed circuit board is provided with a frequency conversion unit for converting the frequency of power-frequency electricity and then transmitting the electricity to the frequency conversion unit of the frequency conversion motor. In the frequency conversion device mounting structure, the frequency conversion device can be mounted in the motor cavity of the submersible pump.

Description

technical field [0001] The invention belongs to the technical field of submersible pumps, and relates to an installation structure of a frequency conversion device of a submersible pump. Background technique [0002] At present, submersible pumps use ordinary motors, which are difficult to improve the efficiency of the impeller due to the limitation of the speed. [0003] The submersible pump is composed of a pump and a motor. The motor drives the impeller in the pump to rotate. It is difficult for ordinary submersible pumps to exert the benefits of the impeller. Therefore, it is equipped with a frequency conversion device to increase the speed of the motor. The existing submersible pumps use an external frequency converter to achieve frequency conversion, and setting the frequency converter outside the frequency conversion motor is prone to moisture, which reduces the service life of the frequency converter; There are potential electrical safety hazards, and the existing f...
