Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a high-performance water pump. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] The existing ordinary water pumps have low output efficiency when in use. If they are replaced with large water pumps with a high success rate, not only will the cost increase, but the volume of the water pump will also increase too much, affecting its use. Therefore, it is necessary to make minor modifications to the ordinary water pumps to increase their water pump performance and improve their output efficiency without increasing the cost and volume too much.

[0006] Preferably, a sealing rubber ring is provided between the water pump lower shell and the water pump upper shell.

[0007] Preferably, the length of the motor body and the length of the water pump upper shell are both extended by 8.5 mm.

[0008] Preferably, the single-piece shape of the water pump impeller is a right-angled trapezoidal shape with a large root and a small front end.

[0009] Preferably, the water pump impeller has 6 blades, which are evenly distributed.

[0010] Beneficial effects

[0011] The utility model provides a high-performance water pump. Compared with the existing technology, it has the following advantages:

[0012] This high-performance water pump extends the motor body length by 8.5mm, which increases the length of the motor rotor, also known as the motor shaft length, thereby improving the output power and efficiency of the motor, thereby improving the performance of the water pump.
