In addition, existing high-pressure cleaning pumps cannot detect the internal water pressure in real time, which results in poor practicality of the high-pressure cleaning pumps. Utility Model Content

[0009] In some embodiments, a centrifugal motor is fixedly installed in the main housing, and the end surfaces of the two groups of centrifugal shafts that are symmetrical on both sides and close to the symmetry center are dynamically connected to the centrifugal motor.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] 1. The utility model starts by a centrifugal motor, thereby driving the left-right symmetrical centrifugal shaft to start high-speed rotation, and then driving the cam to start centrifugal movement, thereby driving the swing rod to start circular swinging, and then the pressurizing frame starts to move back and forth, and the water entering the cavity is pressurized. When the pressure reaches a certain level, the decompression spring begins to contract, and the lifting frame begins to move upward. At this time, the pressurized water is discharged from the discharge pipe, thereby ensuring that the subsequent cleaning can reach the purpose of high pressure. An ultra-high pressure pressure gauge is provided to ensure real-time monitoring of the water pressure entering the cavity, thereby ensuring whether the pressure of the high-pressure cleaning pump is abnormal and timely shutting down the high-pressure cleaning pump, thereby ensuring the stability and safety of the high-pressure cleaning pump during operation.

[0012] 2. The utility model rotates the manual valve, and a part of the high-pressure water flows into the water pipe to reduce the pressure in a curve. At this time, the water flows into the pressure-reducing chamber, and is blocked by the pressure-reducing filter plate, and then the pressure is reduced for the second time, thereby ensuring that the water pressure can be reduced in time, and then the water pressure released by the high-pressure cleaning pump can be adjusted when it is working, thereby improving the flexibility and convenience of the cleaning pump device during use, and further reducing the damage caused by excessive water pressure, thereby preventing the cleaning object from being damaged.

[0026] A lifting chamber 27 is provided in the support frame 20 and is interconnected with the entry chamber 34.

[0029] Specific workflow:

[0030] During use, outside water begins to flow into the inlet pipe 22, and then enters the inlet chamber 34 through the one-way valve 33. At this time, the centrifugal motor 17 starts to start, thereby driving the left-right symmetrical centrifugal shaft 18 to start high-speed rotation, and then driving the cam 19 to start centrifugal movement, thereby driving the swing rod 16 to start circular swinging, and the pressurizing frame 15 starts to move back and forth.

[0031] When a high-pressure cleaning pump is needed to clean different materials, the user starts to turn the manual valve 23. At this time, a part of the high-pressure water flow enters the water pipe 24 and performs a curved pressure reduction. At this time, the water flows into the pressure reduction chamber 30, and then passes through the pressure reducing filter plate 29 for a second pressure reduction, thereby ensuring that the water pressure can be reduced in time, and then the water pressure released by the high-pressure cleaning pump can be adjusted when it is working, thereby improving the flexibility and convenience of the cleaning pump device during use, and further reducing the damage caused by excessive water pressure, thereby preventing damage to the cleaning objects.
