Hydraulic Start/Stop Automatism

The compact power pack, type KA from HAWE Hydraulik works similarly efficient as the automatic start-stop mode in a modern car. When a driver goes into freewheeling during standstill, the engine turns off and burns no fuel anymore. Likewise, the power pack in a machining center is only activated if hydraulic energy is required to actuate a function. If no hydraulic function is activated, a pressure switch will automatically turn the power pack "off" and it no longer consumes electric power. It works because on account of their system the hydraulic functions of the machining center are leakage-free. This is a good condition for designing the power pack for intermittent service. To achieve this, the BVH type valve bank is connected to the pump's compact power pack via leakage-free directional-seated valves, which maintain the pressure that has built up in the system when closed. Due to its oil-submerged construction the hydraulic liquid cools the motor so much that it can be dimensioned particularly small. Not only does this cut down the power pack's building size but it also reduces the accelerated mass, which saves additional energy.
