[0033] The pump head assembly 101 is used to realize the water pumping action. During the water pumping operation, the mounting disc 16 drives the ceramic blade 15 to rotate at a high speed, thereby forming a negative pressure in the pump body 11, and then the external water source can enter the pump body 11 through the water inlet pipe 13 and then be discharged through the drain pipe 14.

[0034] Since the ceramic blade 15 is made of ceramic material, the ceramic material is known for its high hardness, so it can resist the impact and friction of particles, thereby significantly reducing the wear rate of the impeller. In long-term operation, the ceramic impeller can maintain good shape and dimensional stability, thereby prolonging the service life of the submersible pump.

[0035] The ceramic blade 15 is designed to be detachable, so that the ceramic blade 15 can be individually disassembled and replaced without disassembling the entire submersible pump, thereby greatly simplifying the maintenance process and reducing the maintenance cost and time. When a ceramic blade 15 is severely worn, it can be quickly replaced to avoid causing greater damage to the entire submersible pump.

[0041] Through the cooperation of the casing 31 and the end cover 32, the transmission motor 33 can be sealed and protected, avoiding water damage to the transmission motor 33. By driving the mounting disc 16 with the transmission motor 33, the ceramic blade 15 can be rotated at high speed, thereby realizing the pumping operation.

[0042] In operation, the submersible pump is placed in the working water area, the drain pipe 14 is connected to the external water pipe, and then the transmission motor 33 is powered on. The transmission motor 33 works, the output shaft of the transmission motor 33 drives the mounting disc 16, the mounting disc 16 drives the connecting seat 19, the connecting seat 19 drives the ceramic blade 15, and with the high-speed rotation of the ceramic blade 15, a negative pressure is formed in the pump body 11, and then the external water source enters the pump body 11 through the water inlet pipe 13, and then is discharged through the drain pipe 14, to complete the pumping operation.

[0043] When it is necessary to replace the ceramic blade 15, the submersible pump is powered off and taken out of the water, the pump shell 12 is disassembled, and then the limiting plate 21 is disassembled. At this time, the damaged ceramic blade 15 can be taken out, and the replacement of the ceramic blade 15 is realized.

[0044] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
