Water jet cutter description :

The working principle of our water jet cutter:

The basic working principle of ultra-high pressure waterjet is simple and extremely complicated. The key to the formation of ultra-high-pressure water is the high-pressure pump. The low pressure oil from the oil pump pushes the large piston of the supercharger to make it reciprocate. The moving direction of the big piston is automatically controlled by the reversing valve. On the other hand, the water supply system is purified first, and then the low-pressure water is pumped out by the water pump. After the low-pressure water entering the booster is pressurized by the small piston, the pressure rises. Because the high-pressure water is produced after the supercharger is continuously compressed back and forth, and the piston of the supercharger needs to be reversed, the pressure of the water jet emitted from the nozzle is pulsating. (Water cutting processing) In order to obtain a stable high-pressure water jet, it is necessary to make the generated high-pressure water enter an accumulator, and then flow to the nozzle, so as to achieve the purpose of stabilizing the pressure. The basic working principle of waterjet is simple and extremely complicated by ordinary water ultra-high pressure waterjet. The key to the formation of ultra-high-pressure water is the high-pressure pump.

(Water cutting processing) In order to obtain a stable high-pressure water jet, it is necessary to make the generated high-pressure water enter an accumulator, and then flow to the nozzle, so as to achieve the purpose of stabilizing the pressure. The water jet is made by ordinary water passing through an ultra-high pressure pressurizer to pressurize the water to 4,000 bar (60,000 psi), and then passing through a very small nozzle (with a diameter of about 0.1mm to 0.4mm) to produce a speed per second A water arrow that is nearly a kilometer (about three times the speed of sound). This water arrow is like a sharp sword for cutting, cutting the workpiece that needs to be processed.

The composition of waterjet processing equipment includes: ultra-high pressure pump, waterjet cutting head device, waterjet X-Y movable plane cutting table, CNC controller and CAD/CAM software package, etc. The key equipment is: the ultra-high pressure pump increases the water pressure to be able to cut a variety of materials, the higher the pressure, the more it can penetrate a variety of different materials; the waterjet cutting head device contains a small diameter gem nozzle, usually Red or sapphire, this kind of jewel nozzle is inlaid in the metal material, and the nozzle is installed on a shelf that can be adjusted up and down, so that the high-pressure water arrow can accurately pass the position to be processed without damaging any other parts of the workpiece. This is also an important factor to ensure the accuracy of waterjet cutting.

How to choose a better water jet cutter?

The choice of water jet cutting machine mainly considers two parts: high-pressure system and CNC cutting platform. Different high-pressure systems and different cutting platforms can form cutting equipment suitable for different fields. If you choose the type and thickness of the material to be cut before selecting the equipment , The cutting surface and cutting speed requirements for a rough thinking will be helpful to you.

1. Selection of high-pressure system:

Mainly according to the type of cutting material, thickness, cutting surface quality and cutting speed requirements.

·420MPA high-pressure system: 37KW (50HP), the main components of the whole machine include: supercharger, reversing valve, main motor, oil pump, PLC, electrical components, etc., all adopt world-class brands to provide more superior performance and stability.

2. Selection of CNC working platform:

Mainly depends on the size of the cut material.

·Gantry type: compact structure, convenient installation, suitable for the occasions where the material size is relatively fixed, the loading and unloading is relatively convenient, or the loading and unloading method is relatively fixed.

·Cantilever type: the movement mechanism and the cutting platform are separated without affecting each other, and the space for loading and unloading is large. It is especially suitable for the situation of irregular material size and unfixed loading and unloading methods. If you purchase equipment, it is mainly to undertake external cutting processing , It is recommended to use the cantilever type.

·Dimensions: The choice of the size of the CNC cutting platform should first consider the shape of the workpiece (ie, the cutting stroke), and then consider the issue of cutting and the size of the material itself, which will help you make an economical and practical choice Of course, future development and changes should also be considered.

·Electric drive mode: If the cutting speed is greater than 3000mm/min, the CNC cutting platform is recommended to be driven by a servo motor.

3. Other optional items:

·Automatic sand feeding system: In order to reduce labor intensity and avoid cutting interruption caused by the operator forgetting to add sand in time, an automatic sand feeding system can be selected. This system can be used by two machines at the same time, so it is recommended to choose when there are two machines. .

·Double cutting head: If the workpiece is not large (generally less than 600mm), and the batch is large and the variety is small, you can also choose double head or multiple head cutting, so that a machine has higher efficiency, but the high-pressure system requires It adopts a high-pressure system of type 50B that is 37KW (50HP) or greater horsepower.

·Soft water treatment: If you choose 40B or 50B high pressure system, it is recommended to choose soft water treatment system to extend the service life of high pressure seals.

If you can describe your requirements in detail, we will help you choose a suitable plan based on your actual situation.
