Manuelle Paletten-Entkopplung
|
These power units are used with manual Pallet Decouplers with the optional automatic-shutoff feature.
|
Control box has a selector switch with three positions: "unclamped", "clamped", and "couple", with a green signal lamp for "clamped" position.

BESONDERHEITEN: Electric Powers Units are the best power source for most work holding applications, complete with all electrical and hydraulic controls. Quiet, long-life radial piston pump powered by a totally enclosed fan-cooled universal motor. Large reservoir provides enough fluid capacity for virtually any fixture. Leak-free poppet valves and fittings.
MANUELLE PALETTEN-ENTKOPPLUNG: The configuration shown here has a special control box with a selector switch that has three positions: "unclamped", "clamped", and "couple", with a green signal lamp for "clamped" position. Two solenoid-operated clamping valves provide one clamping-pressure port "A" and one unclamping-pressure port "B" (the same power unit and Pallet Decoupler can be used for either single-acting or double-acting systems).
MODELLVARIANTEN: Choice of several different power supplies and maximum operating pressures — see Dimensions page for part numbers:| | 500 bar, 460 Volts, 3 Phase | | | 500 bar, 230 Volts, 3 Phase | | | 350 bar, 460 Volts, 3 Phase | | | 350 bar, 230 Volts, 3 Phase | | | 350 bar, 230 Volts, 1 Phase | | | 350 bar, 115 Volts, 1 Phase |
ARBEITSGANG: The heart of this unit is a precision, long-life radial-piston pump controlled upon demand by an integral pressure switch. This switch is infinitely adjustable from 1500 psi to the maximum operating pressure. Automatic pressure control is assured, because the pump restarts if pressure drops. Clamping pressure is assured even with an electrical power failure since the solenoid valves are mechanically held in "clamped" position, requiring power only to unclamp. The poppet design of these valves ensures positive, leak-free sealing.
MONTAGE & SET-UP: Mount power unit upright, preferably above fixture level to keep the unit clean. We offer a sturdy, attractive Power-Unit Stand (CLR-3532-168-PUA) that bolts to the floor. Power units can also be mounted on the machine tool using an angle bracket. Connect to a fused electrical supply and fill with clean, approved Hydraulic Fluid. Do not use NPT fittings for hydraulic connections.
SAFETY BESONDERHEITEN: Fail-safe operation in case of electrical-power failure since the solenoid-operated clamping valves are de-energised in "clamped" position. These valves are poppet type, so they provide tight zero-leakage sealing. Pump motor has a thermal-overload relay with manual reset.
EINSCHALTDAUER: Electric Power Units are designed specifically and purely for work holding, with intermittent clamping and unclamping between machining cycles (not continuous running). For most work holding applications, actual running time is a small percentage of total cycle time. Run time must be less than 40% of total cycle time at maximum fluid level (25% at minimum fluid level). Run time must also be less than 120 continuous seconds at maximum fluid level (15 seconds at minimum fluid level). Otherwise the fluid will overheat and the unit will shut off automatically. |
