The workpiece can be carved arbitrarily under the control of a computer, and the influence of the material texture is small. Because of its low cost, easy operation, high yield, water cutting is becoming the mainstream cutting mode in the industrial cutting technology, and water cutting machine is superior to other processing technologies, such as flame cutting, plasma processing, laser processing, electric spark processing, turning, milling and planning.

The water cutting machine is widely used in the current production due to the advantages of the water cutting machine, when the water cutting machine works, a supercharger is needed, the supercharger mainly comprises a water pump and an oil pump, when low-pressure water or hydraulic oil acts on a piston, a high-pressure plunger rod connected to the piston pushes water in a high-pressure cylinder out, and the pushed water is connected to a water knife cutter head through a guide pipe to form a water knife. The existing water cutting pressurizer has the following defects:

1. water cutting supercharging device kinetic energy on the existing market is single, relies on oil pump and water pump to produce kinetic energy completely, leads to the burden of water pump and oil pump to increase, reduces the life of water pump and oil pump, in addition, among a lot of operational environment, can't ensure water source department hydraulic stability, and then lead to water flow path water pressure unstability in the booster, the corresponding water sword pressure that can lead to cutting tool bit department to form is unstable, influences the cutting effect in the production.

2. The water jet cutting equipment is generally longer in time of use, the oil of the supercharger can generate high temperature when working, the oil tank is easily overheated due to the fact that the oil circulates in the oil tank all the time, and in addition, the water jet needs to be used for a long time, and certain potential safety hazards exist.

To this end we propose a single pressure boosting device of a water cutting apparatus to solve the above problems.
