Increasing energy efficiency in cooling and lubrication systems
The machining center was equipped with a control pump for the hydraulics for clamping, gripping, straightening and weight compensation as well as with a fixed displacement pump for the filter/cooling circuit. The system had an installed capacity of 5.5 kW.
The Rexroth 4EE Solution
A variable speed pump drive with a connected load of only 4 kW produces the required flows on demand and lowers rotational speeds in partial load operation as needed. This reduced the amount of cooling needed, even more so because the Rexroth specialists rerouted the tank line through the filter/cooler. Moreover, Sytronix simplifies the engineering significantly.
By switching to a variable speed pump drive, the energy consumption of the hydraulic system in this machining center drops by 45 percent.
With the Rexroth 4EE systematic approach, our industry and technology specialists will support you in identifying and realising all potential energy savings in your application. This will allow you to answer your customers' requirements for lower energy consumption and maximum productivity.
