○ Installation space 35% down (our standard unit ratio)
○ At time of accumulator (option) installation → Even when stopped. it maintains the pressure. so the energy-saving effect is greater
1. The NRP series power package is a hydraulic package for intermittent operations (electric motor ON-OFF). If the load operation time is excessive or a mistaken operational method is used. there is a danger of damage to the device resulting from the heating of the electric motor and hydraulic fluid. so use the unit only after reading the instruction manual carefully. Load operation hour rate 1.2kW-4P···15% 2.4kW-4P···10% 2. In order to carry out intermittent operations. it is necessary to set up a pressure switch. etc. inside the circuit and have a circuit that turns the points of contact on the power source side ON and OFF. 3. When carrying out an overhaul. release the bleeder valve to let out the pressure inside the accumulator first. (At the time of accumulator installation) 4. The accumulator (optional specifications) is filled with nitrogen gas. When discarding an accumulator. be sure to remove the gas first. 5. The transportation and installation of accumulators (optional specifications) is subject to regulations so contact our company regarding the details.
1. Operate the unit after confirming with a fluid level gauge whether the hydraulic fluid inside the tank satisfied the prescribed level (the lower limit value or above). (1) Upper limit: prescribed volume of hydraulic fluid (nominal capacity) (2) Lower limit: minimum hydraulic fluid level 2. Connect the electrical wire connections without any mistakes as follows.
1. General mineral oil type hydraulic fluid equivalent to viscosity grade ISO VG32
1. oil temperature : use in a range of 5~60°C. 2. Timing of hydraulic fluid replacement At the beginning. replace the fluid after three months of operation. Subsequently. replace the fluid when it is contaminated or after every one year has passed. 3. Inspection of the inside of the tank and the strainer: every three months. 4. Gas sealing of the accumulator (optional specifications) is not possible. Regular replacement will be necessary.
1. temperature : 5~35°C 2. Ensure that water-soluble cutting fluid mist does not get deposited on the unit.
