Novel structural material water pump

Abstract

The invention discloses a novel structural material water pump, and belongs to the field of water pumps. The friction force is reduced by inlaying a smooth lining on the inner wall of a flow channel of the water pump, the smooth lining is more durable than a coating, and water flow is guided into the water pump through a turbulent flow reducing piece, so that internal turbulent flow can be effectively reduced when the water flow impacts the surface of the smooth lining, and the vortex resistance of water flow is reduced to the maximum extent; the water flow enters a receding bag through a turbulent flow reduction piece, particle impurities carried in water are left under the interception effect of impurity removal particles, and therefore damage of impurities to the interior of the water pump is reduced, and the smoothness of the flow channel is effectively kept; the impurity removal effect can be improved through the further filtering effect of filtering balls, when the water flow enters the turbulent flow reducing piece, one part of the water flow impacts a one-way flow limiting piece to open the one-way flow limiting piece, so that one part of the water enters the abdicating bag from the water inlet channel, the impact force borne by the smooth lining is effectively relieved, and the service life of the smooth lining is prolonged.

Description

technical field [0001] The invention relates to the field of water pumps, and more specifically, relates to a new structural material water pump. Background technique [0002] 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 t...

Problems solved by technology

[0004] In order to reduce the friction between water and the flow channel, the current common practice is to spray the coating on the flow channel, but the adhesion of the coating is not strong, and it is easy to crack and fall off under long-term water washing, and the cost of the spraying process is high. Difficult to operate
