INNOVATION AND TECHNOLOGY

Core Technology - Proven & Reliable

The TECHNI Waterjet™ Quantum ESP™ (Electric Servo Pump) incorporates core “servo” technology that was first applied by NASA for the Space Shuttle Program by replacing old-fashioned hydraulic cylinders with new, highly compact, efficient, reliable and infinitely controllable Servo Linear Actuators. This same style actuator is used today in many high end machine tools and presses replacing inefficient hydraulic systems. Similarly, TECHNI Waterjet™ is the first waterjet manufacturer to utilize “servo” technology in an ultra-high pressure waterjet pump and has developed patented designs to integrate the core technology into the world’s first, most efficient, reliable and controllable ultra-high pressure (UHP) waterjet cutting pump.

Existing Technology - The Best of Both Worlds

Traditional UHP pumps fall into 2 main categories, the Intensifier Pump, and the Direct Drive Crank Shaft Pump. These 2 pumps offer very different benefits from each other but also both have considerable limitations. The Intensifier Pump is capable of producing higher pressures, can support multiple nozzles with varying size orifices, and can be “dead headed” by holding pressure without any water being displaced. While dead heading is desirable, intensifiers have a pressure spike of 5-10% when dead heading, which is harmful to the UHP components and is a significant cause of failure in UHP pipes and fittings. However, these pumps are very inefficient, large and noisy. Direct Drive Crank Shaft Pumps are smaller, quieter and more efficient, but must displace the water whenever the motor is on, which is done by directing the water over a relief valve to drain. This means that they are not practical to run multiple heads or varying orifices as the unused water and energy is wasted. They are also not suitable for running varying pressures, and are less reliable than intensifiers due to their high plunger speeds. The Quantum ESP™ takes all of the best features of the 2 existing technology UHP pumps, with none of their limitations.

New Technology - The Future in Waterjet Cutting

The Quantum ESP™ is a revolutionary concept in waterjet cutting incorporating a Servo Motor directly enveloping a high load, precision ball screw. The ball screw directly houses the ceramic plungers, which reciprocate back and forth to create the pumping action, in much the same way as the hydraulic cylinder works on an Intensifier Pump. The infinite control of the Servo Motor and precision of the ball screw, enable extremely accurate control over the output pressure and volume of the water displaced, and eliminates pressure spikes when dead heading. This infinite control gives an operator the ability to program virtually any pressure and flow rate from zero up to the full capacity of the pump, while only using the power displaced at the cutting head.

Real Efficiency - Real Savings

The Quantum ESP™ is by far the most efficient UHP pump available on the market, delivering “real” efficiency gains. Direct Drive Crank Shaft Pumps have traditionally been marketed for their efficiency, however, they are only efficient while the cutting head is open and the full capacity of the pump is being used. When the head closes while the machine positions for the next cut, or the material is being unloaded and re-loaded, almost all of their energy is directed over a relief valve, literally sending power, water, and money down the drain. Intensifier pumps are inherently less efficient due to the power required to simply run the hydraulic system. They also use a large percentage of their power regardless whether cutting or idle as the oil is passed over a relieve valve in the hydraulic system. The Quantum ESP™ only ever uses the power required for the cutting process. This means that regardless of whether the cutting head is open or closed, or the pressure or flow is reduced, there are no additional power losses. The below graph highlights the increasing efficiency gains achieved with the Quantum ESP™ as duty cycles decrease.

The Quantum ESP™ software diagnostic screen gives a quick and easy-to-read analysis of the pump performance, with an in-time graphical representation of the relationship between volume, pressure and maintenance of the pump at all times. This will help the operator determine the correct set up for a given application.
