Embodiment Construction

[0037] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] combine figure 1 As shown, the booster water pump in this embodiment includes a housing 1 and a piston 2 . A control chamber and a working chamber 12 distributed along the axial direction are arranged inside the housing 1 . A P port, a T port, a water inlet 13 and a water outlet 14 are provided on the housing 1 , and the P port and the T port communicate with the control chamber, and the water inlet 13 and the water outlet 14 communicate with the working chamber 12 . Wherein, by installing corresponding one-way valves at the water inlet 13 and the water outlet 14 respectively, the low-pressure water flows into the working chamber 12 through the water inlet 13 and the high-pressure water flows out of the working chamber 12 through the water outlet 14 one-way.

[0039] The piston 2 is axially divided into a bi...

Abstract

The invention belongs to the technical field of water pumps, and discloses a booster water pump. The booster water pump comprises a shell and a piston, a control cavity and a working cavity are formedin the shell, a P port, a T port, a water inlet and a water outlet are formed in the shell, the large end of the piston divides the control cavity into a left control cavity and a right control cavity, the P port and the T port are alternately communicated with the left control cavity and the right control cavity so as to drive the piston to move reciprocally, the small end of the piston is located in the working cavity, and the water inlet and the water outlet are communicated with the working cavity; and when the piston performs axial reciprocating linear movement to a terminal position along the control cavity, the piston rotates around the circumferential direction, and the communication relationship between the and T ports and the left and right control cavities is switched, so thatthe continuous compression acting and output of the working cavity on water are realized. The booster water pump not only has higher working reliability and stability, but also is more compact in structure and lower in maintenance and use cost.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and in particular relates to a booster water pump. Background technique [0002] The booster water pump is an important high-pressure water supply component widely used in water cutting, high-pressure cleaning and other fields. At present, the traditional booster water pump used in China controls the reciprocating motion of the booster water pump to continuously output high-pressure water through the continuous reversing of the electromagnetic reversing valve. [0003] The traditional booster water pump not only has a complex structure, but also requires complex displacement sensors and electronic control components, and the commutation is unstable and unreliable. At the same time, because the control circuit part of the reversing device is controlled by a circuit board, because the circuit board is a non-standard part, and it is difficult to manufacture and process, it is very difficult to ...
