Energy efficient cutting with quickly reacting plunger pumps
Industrial water jet cutting with high energy efficiency
The optimal use of available resources not only protects the environment, it is also a deciding factor for economic success. Fast-switching high-pressure pumps from Hammelmann impress with their outstanding implementation of available energy and maximum reliability in daily operation.
Energy usage of a cutting nozzle with a coefficient of discharge of 0.7 and an operating pressure of 3800 bar.
Hammelmann high-pressure pumps make particularly economical use of the energy employed. With these high-pressure systems it is possible to use the exact motor power necessary for the actual cutting task in progress. Additionally the high mechanical and volumetric efficiency of the cutting pump result in considerable energy savings.
Comparing energy requirements of intensifiers with load sensing systems and Hammelmann plunger pumps using 1 to 4 cutting nozzles, each with an orifice diameter of 0.25 mm and an operating pressure of 3800 bar.
Water jet cutting appliances often use oil hydraulically driven intensifiers. Whereby only about 60% of the energy drawn is in effect used for the regulation and provision of the actual required cutting performance. An enormous energy loss. The directly driven Hammelmann plunger pumps distinguish themselves, in comparison to intensifiers with load sensing systems, by a higher degree of efficiency of up to 30%.
Easy integration into existing system and fast retrofitting
Hammelmann water jet cutting units with fast-switching high-pressure pumps have no need for complicated valve technology and are compatible with all cutting tables thanks to direct pressure control. The use of particularly fast-reacting reluctance motors in combination with the high efficiency of Hammelmann high-pressure pumps enables the simultaneous and demand-oriented supply of several cutting heads without pressure losses or start-up times. The pumps are controlled by their own control unit and an intervention in the existing control of the cutting table is not necessary. A retrofit or an exchange of pressure intensifier systems, is not a problem. Your cutting tables are ready for use again in a very short time and immediately operate more economically and energy efficient than before.
- Demand-oriented supply of high-pressure water
- High energy efficiency
- Capable of feeding 10 cutting heads with a single unit
Common Rail
Special advantages result from the combination of several pump units in a common rail system. The intelligent, central controller freely defines which pumps are used as pressure generators. This ensures that use of all pumps takes place as uniform as possible and the pumps deliver the required power under optimal utilization. As a result, there is a homogeneous load on all pump units on a daily average. In this way, the wear of individual components is reduced and maintenance intervals are maximized, which leaves a positive impact on service and repair costs. Since individual pumps can be purposefully removed from the existing network, maintenance during operation is possible. This option also has a positive effect in the event of an incident. If a pump fails in the system, the power it provides is distributed without any delay in the network, without system shutdowns occurring.
- No change in existing control needed
- Energy efficient
Master control unit
The master control is the control center in the common rail system. A touchscreen can manage and monitor up to eight pumps. Each integrated pump has its own data logger, which provides detailed information about the life cycle of the pump. Pumps can be conveniently taken out of the system by the central control unit to make these available for service, for example. Specially designed submenus ensure intuitive operation and clear presentation of the information provided.
