60000psi Chinese Wamit Patent Product High Pressure Waterjet Cutting Direct Drive Pump

WAMIT servo direct drive pump represents a new generation of high-efficiency, energy-saving ultra-high pressure pump, which is the first large R&D in China. Servo motor driven direct drive intensifier system. Power is only 15kw, which can save you 60% to 70% cost.

Advantages of the WAMIT servo direct drive pump:

A: Energy saving: The main motor adopts a torque motor of 15KW, compared with the motor of the 37KW hydraulic high pressure intensifier system, the power consumption can be saved by 60%-70%.

B: Environmental protection: the use of servo direct drive, no hydraulic system, with self-cooling function. As we all know,
hydraulic The hydraulic intensifier system must be filled with 110L of anti-wear hydraulic oil to work, and the heat generated by the hydraulic oil is also cooled by the oil cooler. The direct drive pump is completely free of hydraulic oil and cooling system.

C: High efficiency: Direct drive pump provides a higher pressure output ratio, cutting speed is 20 to 50% faster than the same equipment in the market.

D: Low noise: almost no noise when working.

E: Small weight: The total weight of the direct drive pump is less than 600kg, and the movement is flexible. The weight of the hydraulic intensifier pump is 1000kg. G: Beautiful appearance: The structure is reasonable in design and beautiful in appearance, because the direct drive pump does not have a hydraulic system, Thereby avoiding the leakage of the hydraulic oil (the hydraulic seal will be damaged for a long time use, causing the hydraulic oil to leak), eliminates the contamination of equipment by oil stains.

The control principle of the Volmet servo direct drive supercharger:

The direct drive supercharger 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.
