Variable-pressure water pump with stable output

Abstract

The invention discloses a variable-pressure water pump with stable output, and relates to the technical field of variable pressure water pumps. The variable-pressure water pump comprises a variable-pressure water pump body and a water outlet pipe communicating with a water outlet of the variable-pressure water pump body, a water pumping assembly is arranged at a water inlet of the variable-pressure water pump body, and a vibration and noise reduction assembly is arranged at the bottom of the variable-pressure water pump body; and the water pumping assembly comprises a water pumping pipe, one end of the water pumping pipe communicates with the water inlet of the variable-pressure water pump body, the bottom end of the water pumping pipe is in threaded connection with a connecting flange, and the interior of the connecting flange is fixedly connected with a fixing cylinder. According to the variable-pressure water pump with stable output, impurities and acidic substances in water can beadsorbed and filtered in the water pumping process, meanwhile, an activated carbon filter screen and an adsorption bag can be cleaned or replaced conveniently, and according to monitored water flow and pressure signals, therefore, personnel can conveniently adjust the output pressure of the variable-pressure water pump body, and different use requirements are met.

Description

technical field [0001] The invention relates to the technical field of variable pressure water pumps, in particular to a variable pressure water pump with stable output. Background technique [0002] A water 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, emulsions, and suspoemulsions. It can also transport liquid, gas mixture and liquid containing suspended solids. 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 water pumps, vane pumps and other types, volumetric pumps use the change in the volume of their working chambers to transfer energy; vane pumps use the interaction between rotating blades and wat...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a variable pressure water pump with stable output, which solves the problem that the water contains many fine impurities and a small amount of acidic substances, which are difficult to clean during the pumping process, and enter the interior of the water pump to affect its service life. At the same time, the flow and pressure of the water flow are not monitored on the variable pressure water pump, which is not conducive to the problem of adjusting the output pressure of the water supply
