Embodiment Construction
[0030] see Figure 1-5 As shown, a booster water pump includes a pump casing 1 with an axial tunnel. The side wall of the pump casing 1 is provided with a P oil port 001 and a T oil port 002 communicating with the axial tunnel. The inner hole wall of the pump casing 1 The middle part has a first annular inner shoulder 101 , and the P oil port 001 and the T oil port 002 are located on the left and right sides of the first annular inner shoulder 101 .
[0031] A left cylinder body 2 with a left large plunger chamber 2a and a left small plunger chamber 2b, and a right cylinder body 3 with a right large plunger chamber 3a and a right small plunger chamber 3b, the left cylinder body 2 and the right cylinder body The bodies 3 are respectively connected to the left and right ends of the axial channel of the pump casing 1; the left cylinder body 2 is provided with a left water inlet hole 201 and a left water outlet hole 202 connected with the left large plunger chamber 2a, and the rig...

The invention discloses a booster water pump. The booster water pump comprises a pump shell with an axial hole channel, a left cylinder, a right cylinder, a piston, a large valve core and a small valve core; an oil port P and an oil port T which communicate with the axial hole channel are formed in the side wall of the pump shell; the left cylinder is provided with a large left plunger cavity anda small left plunger cavity, and the right cylinder is provided with a large right plunger cavity and a small right plunger cavity; the piston is provided with an axial channel, is in a T shape, is arranged in the pump shell and can slide left and right; the diameter of the large valve core is greater than that of a valve port, and the large valve core is located on the left side of a second annular inner protruding shoulder and slidably connected into the axial channel of the piston; a large left plunger is mounted at the left end of the axial channel of the piston, and a large right plungeris mounted at the right end of the axial channel of the piston; a small left plunger is mounted on the left end face of the piston, and a small right plunger is mounted on the right end face of the piston; and a left variable control valve assembly and a right variable control valve assembly are mounted in the left cylinder. The booster water pump is simple in structure and can realize the variable booster ratio.
Description
technical field [0001] The invention relates to the technical field of water pumps, in particular to a booster water pump. Background technique [0002] The booster water pump is an important high-pressure water source supply component widely used in water cutting, high-pressure cleaning and other fields. The existing booster water pumps generally have a fixed booster ratio, but in actual applications, different working conditions are usually required. Boosting ratio, for example, in the medium and low pressure stage, the outlet pressure is not high at this time, but the demand flow is large, and only a small boosting ratio is needed to reach the required pressure; while in the high pressure stage, the outlet pressure is high at this time , while the outlet flow rate is required to be small, and a large boost ratio is required to achieve the required pressure. In current applications, a water pump with a large boost ratio and a pump with a small boost ratio are mostly used ...
