Special water pump unit for preventing gravel blockage

Abstract

The invention discloses a special water pump unit for preventing gravel blockage. The special water pump unit for preventing gravel blockage comprises a bottom plate, wherein a unit installation baseis fixedly arranged at the upper end of the bottom plate; a shock pad is arranged at the upper end of the unit installation base; a water pump unit body is fixedly arranged at the upper end of the unit base; a shower nozzle connector is fixedly arranged at the lower end of a water inlet pipe; a screw thread matched with a screw groove is arranged on the upper end surface of a water inlet cylinderbarrel; a precise filter screen is fixedly arranged at the lower end of the water inlet cylinder barrel; and a coarse filter mesh plate is fixedly arranged at the lower end of a connecting plate and located on the outer side of the precise filter screen. According to the special water pump unit for preventing gravel blockage provided by the invention, impurities in water pumped by the water pump can be firstly coarse-filtered through the coarse filter mesh plate and are then fully filtered through the precise filter screen, so that the water pump unit is prevented from being blocked by gravel;and the whole water pump unit can be shielded through a shielding plate so as to be prevented from exposing to the weather, so that the service life of the water pump unit is favorably prolonged.

Description

technical field [0001] The invention relates to the technical field of water pump units, in particular to a special water pump unit for preventing sand and gravel clogging. 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 rot...
