Choose High Pressure Pump
How to choose the suitable waterjet cutting machine high-pressure pump?

Generally speaking, a waterjet cutting equipment mainly consists of CNC cutting platform and high-pressure pump two major components, cutting platform and high pressure pump has a lot of kinds, they basically can be freely combined. Here to introduce a selection method of high-pressure pump. High-pressure pump is the heart of the machine performance, choose the high-pressure pump first to see the cutting purposes:

If you just cut the sponge, foam sponge, EPE, styrofoam, cardboard, soft rubber sheet and other soft low density materials, only need to choose a lower horsepower pump, such as the 15 to 30 horsepower, pressure less than 350MPa is enough, this kind of material is most suitable for pure waterjet cutting, nozzle used for pure waterjet cutting usually very fine, the diameter of about 0.10 ~ 0.15mm is sufficient, according to production and the choice of multiple cutting heads simultaneously processing, the cutting platform size and the size of the workpiece, configuration of the cutting head can be up to ten or more, as long as the calculated total flow can go to choose the right high-pressure pump based on the total flow, thus saving the purchase cost, but also saves processing costs.

If the cutting of hard or high density materials, such as ceramics, artificial stone, marble, granite, glass, organic glass, acrylic, quartz glass, plastic board, rubber, wood, aluminum, iron, stainless steel, tool steel, copper, titanium, and even hard-alloy materials, it is necessary to use the high-pressure pump of large flow high-powered, but also abrasive cutting, because at this time the cutting forces mainly from sand, high pressure water just sand cutting carrier, high-pressure water the greater the flow, the greater capacity with sand, so to choose a large flow of high-pressure pump. Experience tells us that the single cutting head most appropriate gem nozzle and sand tube diameters were 0.36mm / 1.02mm, this configuration makes it possible to reach the international top manufacturer of waterjet cutting efficiency published data, however, provides 0.36mm nozzle and the maximum pressure 380MPa cutting of high-pressure pump requires a minimum of 40 to 50 horsepower, so this is abrasive cutting single cutting head waterjet cutting machine standard configuration. Similarly, if you need two heads to be abrasive cutting, you need high-pressure pump 75 to 100 horsepower, four heads you need to configure the 150 to 200 horsepower high-pressure pump.
