Water quality requirements report for waterjet cutting

Water quality requirements report for waterjet cutting

For waterjet machines ,water quality is very important,Good water quality can extend the service life of the waterjet pump,Can extend the service life of the nozzle.we analyzed the water quality requirement.

1：poor water quality will produce a lot of scale

2：If the water is acidic,it will corrode the metal,

3：If there are impurities in the water.Diamond orifices will be destroyed quickly

4：Poor water quality will result in a short service life of the filter element 

So water quality is very important.

What are the water quality standards?

Large RO reverse osmosis equipment ues for waterjet

First step:

Use PP cotton fiber to remove sediment and impurities from water.

Second step:

activated carbon fiber,Remove odor, residual hydrogen, microorganisms, etc. from water

Third step:

Remove calcium and magnesium ions from water, remove scale, reduce water hardness, and achieve softening effect

Result：Filtration precision reaches 5 microns

The normal water pressure of water cutting is 380Mpa,which is very high pressure,so,water quality is very important,Under high pressure,any impurities in the water will quickly destroy the seal of the waterjet pump.

Parameter requirements:

Flow:1t/h

Accuracy:5nm

Result:Drink directly

Inter water pressure:0.2Mpa

Purified water (ultrapure water) treatment equipment refers to water in which the conductive medium in the water is almost completely removed, and at the same time, non-dissociated gases, colloids and organic matter (including bacteria) are also removed to a very low level. Its conductivity is generally 0.1~0.055uS/cm, resistivity (25℃) >10MΩ·cm, and salt content <0.1㎎/L. Ideal pure water (theoretically) has a conductivity of 0.055 us/cm and a resistivity ( 25℃) is 18.25MΩ·cm.

This design line is suitable for water cutting equipment use,waterjet machines used in many industries.

 Working principle: This system is an ultrapure water system with relatively mature technology and convenient operation in the domestic market. It adopts the principle of physical reaction plus chemical reaction, that is, when the world's most advanced reverse osmosis system + EDI treatment system + polishing mixed bed Methods to gradually improve water quality; our company selects different treatment methods based on your customers' water quality requirements for production water, with the best cost performance, and ultimately meets the standards for production water.

Design Principles

   1. Strictly abide by national and local laws and regulations;

   2. Select advanced and reliable technologies and equipment to ensure stable system and safe production, and strive to save investment to the maximum extent while improving economic benefits;

   3. Key equipment, instruments and materials are all adopted internationally mainstream advanced and reliable products to meet the high standards, high precision and high requirements of pure water and ultrapure water systems;

   4. Strictly implement national safety, environmental protection, fire protection, labor safety and health standards and regulations, and adopt various practical accident prevention and handling measures to ensure the smooth implementation of the project;

   5. The system layout and pipeline layout shall be based on the principle of meeting production needs, safety production, fire protection and other requirements;

   6. Learn from the operating experience of similar devices in the same industry and related industries at home and abroad, adopt mature, reliable, advanced and reasonable water treatment processes, and adopt highly automated and advanced equipment, testing, and automatic control instruments to ensure smooth, safe and reliable system operation. , and ensure that the treated pure water and ultrapure water quality meets product requirements, with high water utilization rate, reliable operation, and economical reasonableness.

   7. Because the equipment is arranged in a humid place, the equipment must have good anti-corrosion capabilities.

   8. The equipment technology is advanced and reliable, and has the ability to operate continuously for 24 hours.
