Knowledge for Water Jet Cutter and waterjet spare parts:

Portable Water Jet Cutter water-sand mixing technology has two kinds of pre-mixed sand and post-mixed sand.
The working principle of pre-mixed sand is: first mix the abrasive and water thoroughly, then put them into a sealed container, then draw the water sand to nozzle and spray out with 30-50mpa pressure.
The advantages of this method are small footprint, easy to move and safety. But the disadvantage is
1. water sand mixing through all the pipes and cutter head and the whole water jet cutting device is easy to wear, life will be relatively short.
2. And because of the small size of the water-sand mixing storage container, usually more than 10 minutes will be used up, at which time you need to stop to add material. Therefore, it can not meet the needs of long time or uninterrupted cutting work.
3. and the container is often open and closed, the seal is easy to wear, high frequency of replacement.
The working principle of post-mixing type is: after first raising the water pressure to 320-360mpa, the abrasive is sucked in during the water jetting and then cut.
The disadvantage of this way is that it covers a relatively large area, the volume is bulky and heavy, moving with the help of tools.
However, the advantages of this method are more obvious:
1, can achieve a long time stable and effective work, uninterrupted
2, related parts and equipment life longer
3, more pressure, higher cutting efficiency
4, also have safety protection, such as pneumatic trolley, explosion-proof motor and electric box.
5, the market is widely used and highly recognized.
