APW waterjet training

In this section, we will detail waterjet installation water requirements. These operating rules require thorough understanding to all of the components.

Water Requirement

Water Requirement

Water Requirement

Intensifier needs two input water sources (cooling water and cutting water), and one drainage line for cooling water. All pipes must correspond with relevant local regulations and national standards.

attention sign

Before pipeline connection, all the pipe fittings need to be well cleaned. It may cause the system pollution if they are dirty.

attention sign

All pipelines shall be installed with a manual shut-off valve. For the convenience of maintenance and installation, the position of a manual shut-off valve should be arranged as close as possible to the connector.

Cutting Water

Input cutting water flows into the intensifier after filtration. Then cutting water will flow into the cutting head. Poor water quality may significantly reduce the service life of the component, and it does not enjoy rights which are listed in the warranty regulations.
Cutting water supply must meet minimum quality requirements. (Please refer to the appendix of "water quality standard")

attention sign

The quality of cutting water is very important, because it directly affects the service life of the equipment. Low water quality can dramatically reduce the service life of parts.

attention sign

The pump filters can only remove the large particles suspended in the water. It will not meet the requirement of our cutting water requirement. Water deionization system is required to increase the water quality.

Only PVC pipe, steel pipe or rubber pipe connection can be used to deliver cutting water to the pump.
Input water pressure should be bigger than 0.3 Mpa. If the water pressure is lower than 0.3 Mpa, a water booster pump is needed.
Minimum inlet flow rate is 15.4 liters/minute.

Cooling Water

Input cooling water flows through the oil/water heat exchanger, in order to control the temperature of the hydraulic oil. Then the used water can be drained or collected and recycled.
Because the inside space of "oil/water heat exchanger (cooler)"is small, so the cooling water should be proper filtered. The filtering precision should not be higher than 5μm. Softened water can prolong the service life of heat exchanger and cooling effect.
Cooling water temperature should be control under 35°C, so that the cooling effect is guaranteed. If the external supply of cooling water temperature is too high, please use other proper cooling equipment.

notice sign

The flow of cooling water should be at least 6 cubic per hour. If you cannot meet this requirement, an additional water pump is needed to increase the flow of cooling water.

notice sign

If the cooling water is recycled, the total water in recycle system should be at least 3 cubic. If the cooling water is less than this, the cooling water temp will increase faster.
