Description

Technical Field

[0001] The invention relates to the technical field of water pumps, in particular to a coaxial differentially driven water pump. Background Art

[0002] A water pump is a general-purpose machine widely used in industry and agriculture. Its main function is to provide power for fluids to achieve liquid transportation, pressurization and transfer. The working principle of a water pump is usually based on Bernoulli's theorem and fluid dynamics. The rotating impeller does work on the fluid to increase the kinetic energy and pressure of the fluid, and then converts the kinetic energy into static pressure energy through the pump casing to achieve fluid transportation.

[0003] CN218894760U discloses a high-power water pump, including a base, wheels, a push rod, a fuel engine, a planetary gear set, and a pump body. There are four wheels, which are respectively installed on the left and right sides of the base. The push rod is installed at the top rear end of the base. The fuel engine, the planetary gear set, and the pump body are sequentially embedded in the slide groove at the front end of the base, fixed with bolts, and connected to each other through a rotating shaft. This technology uses the planetary gear set to increase the original speed without increasing the work consumption of the fuel engine, so that the power of the pump body is doubled, which not only reduces the loss of the fuel engine, but also improves the working efficiency of the water pump. In order to facilitate transportation, the utility model installs wheels and push rods on both sides and the rear end of the bottom plate respectively;

[0004] The above-mentioned water pump is not provided with a component that can be used for filtering. When the water pump is in use, it is very easy for impurity particles in the water to wash the inside of the water pump, thereby accelerating the rust of the pump body and easily causing rupture and leakage. At the same time, when too much impurity accumulates, the impeller port will be blocked, and it will not be able to absorb water from the outside normally, and it will also not be able to drain water normally. Therefore, a coaxial differential drive water pump is proposed to address the above problems. Summary of the invention
