An anti-clogging structure for the inlet of a permanent magnet variable frequency water pump

Abstract

The invention relates to the technical field of water pumps, in particular to an inlet anti-clogging structure for a permanent magnet frequency conversion water pump, which includes a motor and an impeller chamber installed on the output end of the motor, and a water inlet pipe is fixedly connected to the middle of the side of the impeller chamber facing away from the motor. The outer surface of the water inlet pipe is circular and equidistantly installed with several detachable cylinders connected with the water inlet pipe. A piston is slidably installed in the cylinder, and a connecting rope is installed on the end of the piston away from the water inlet pipe. The outer side of the cylinder is connected with a vertically arranged square block. The outer side of the square block is covered with a square sleeve fixedly connected with the cylinder body. The lower surface of the square block is fixedly connected with a vertically arranged round rod. The outer surface of the round rod is from top to bottom, etc. There are several levers installed at the distance. Compared with the prior art, the present invention has the following beneficial effects: it can automatically remove the sundries attached to the water inlet, avoid the water pump from being in an overload state for a long time, and eliminate the need for manual frequent inspection and cleaning, reducing the Difficulty of management.

Description

technical field [0001] The invention relates to an inlet anti-blocking structure for a permanent magnet variable frequency water pump, which belongs to the technical field of water pumps. Background technique [0002] Permanent magnet frequency conversion technology is currently a widely used high-efficiency technology. For now, permanent magnet frequency conversion motors include permanent magnet rotors, because the motor speed can be changed without changing the input power, or the motor speed can be changed without changing the motor speed. Under the circumstances, the input and output power can be changed, so in the process of energy conversion, the energy consumed in energy conversion can be greatly reduced, so a lot of resources can be saved, and it has the advantages of energy saving and environmental protection, and is widely used in various industries.

AI Technical Summary

Problems solved by technology

[0003] At present, in order to prevent the impeller chamber of the water pump from entering sundries and affecting the work of the water pump, a cylinder with water inlet is often installed at the water inlet of the impeller chamber to filter the sundries in the water body. When the sundries in the water body adhere When it is at the water inlet hole on the cylinder, it not only affects the flow of water, but also increases the load of the water pump due to poor water flow. At the same time, the impeller chamber in the water body is difficult to be observed, requiring frequent inspection by personnel, and inconvenient to manage.
