Application and advantages of PMT waterjet cutting:

Product Description
Control Theory of Servo Direct Drive Pump:
PMT25DDP waterjet that is Direct drive pump is a device that directly converts electric energy into hydraulic energy by a crankshaft connecting rod mechanism, and the energy conversion ratio is as high as 97% or more.
The power conversion ratio of the conventional asynchronous motor is 80% and that of permanent-magnet servo motor is 97%; therefore, replacing asynchronous motor by permanent-magnet servomotor greatly improves the power consumption of the intensifier, keeping the conversion rate above 90%; while the energy
conversion rate of the conventional hydraulic intensifier is only 56% (This conversion rate is only in the state of full work.).In the traditional hydraulic system, the asynchronous motor still keeps turning when the waterjet is not cut (such as the movementof the cutting head, changing the cutting material, etc.), and the oil pump is still in working state. Although the pressure of the oil pump is not high at this time, still there is 30% power loss. Even servo power oil pump is used, the asynchronous motorstill has 30% loss if it maintains its own rotation and power magnetic field.
Servo Direct Drive Pump Advantages
1. Selection of motors: 18.5kw, can save power consumption above 60%, 12DEGREE/HOUR electricity consumption if work continuously
2. Pressure conversion methods: can save energy about 35%.
3. Cutting efficiency: greatly improved by 10%-20%
4. working noise is 40DB
5.it is very good for glass and ceramic tiles waterjet cutting.

Q: What is the advantage of water jet cutting machine?
A :Cold processing, no heat reaction zone. no deformation; strong cutting ability, pure water jet can cut soft materials, abrasive waterjet can cut hard materials; can cut flammable and explosive objects;cutting precision is high, edge is neat no secondary processing is required. Waterjet also has the title of universal cutting machine.
Q: How to choose the cutting table?
A:You need to offer the size of the materials you want to process or the size of the cutting table.
Q:How to solve the incision problem of water cutting?
A:It is not a vertical cutting for a waterjet cutter. This is due to the physical characteristics of waterjet. If it is required precise vertical angle cutting, we will provide you with a five-axis dynamic cutting system.
Q:Is the equipment easy to operate?
A:Wonlean intelligent waterjet cutting machine is easy to operate. You could upload the electronic images file of DXF format to the operating system via USB or network. The system will
automatically program, and only need to set a few simple parameters, it can automatically complete the cutting operatioN
