Description

An easy-to-assemble agricultural water pump

technical field

The utility model belongs to the technical field of water pumps, in particular to an agricultural water pump which is easy to assemble.

Background technique

A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsion, suspoemulsion and liquid metal. Liquids, gas mixtures and liquids containing suspended solids can also be transported. The technical parameters of pump performance include flow rate, suction lift, lift, shaft power, water power, efficiency, etc.; according to different working principles, it can be divided into volumetric pumps, vane pumps and other types. Positive displacement pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and water to transfer energy, and there are centrifugal pumps, axial flow pumps and mixed flow pumps. Before starting the water pump, first fill the pump and the water inlet pipe with water. After the water pump is running, under the action of the centrifugal force generated by the high-speed rotation of the impeller, the water in the impeller channel is thrown to the surroundings and pressed into the volute, forming a vacuum at the impeller inlet. The water in the pool is sucked along the suction pipe under the external atmospheric pressure to supplement this space. Then the inhaled water is thrown out by the impeller through the volute and enters the outlet pipe. It can be seen that if the impeller of the centrifugal pump rotates continuously, it can continuously absorb and press water, and the water can be continuously lifted from a low place to a high place or far away. To sum up, the centrifugal pump is called a centrifugal pump because it lifts water to a high place under the action of the centrifugal force generated by the high-speed rotation of the impeller. The working principle of the axial flow pump is different from that of the centrifugal pump. It mainly uses the thrust generated by the high-speed rotation of the impeller to lift water. When the blades of the axial flow pump rotate, the lift generated by the water can push the water from below to above.

The existing agricultural water pumps that are easy to assemble have a high motor temperature due to friction during use, which can easily cause burns to the staff, and the existing agricultural water pumps that are easy to assemble will cause damage to the impeller if foreign objects enter during use problem, for which we propose an easy-to-assemble agricultural water pump.
