what is WAMIT direct drive pump?
The Direct Drive Pump
is a device that directly converts electric energy into water pressure energy by the crankshaft linkage mechanism, and the energy conversion ratio is as high as 97% or more. Since the power conversion ratio of the conventional asynchronous motor is 80%, the permanent magnet servo motor The power conversion ratio is more than 97%, so the servo permanent magnet motor is used instead of the asynchronous motor to greatly improve the power usage of the supercharger, and the conversion rate is maintained above 90%, while the energy conversion rate of the conventional hydraulic booster is only 56%. , (56% 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 movement of the cutter 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, 30% of the power is still present. Loss, even with the servo-power oil pump, the asynchronous motor still has to maintain its own rotation and power magnetic field, still has 30% loss.
This supercharger can completely eliminate this phenomenon. The supercharger adopts the full servo working principle. Only when the cutting head has high pressure water output, the motor works, avoiding the energy consumption of the original hydraulic booster pump in the non-cut state, and achieving the energy saving effect.
