Performance Characteristics Note: The noise characteristics depend on the installation floor, base conditions and the presence or absence of the surrounding substance reflecting the sound, and so may be different from the above description in some cases. ●Type combination ●Mounted manifold block qThe right-hand table Motor kW 0.75 1.5 2.2 shows the standard Pump 0A combination between 1A pumps and motors. wA tank capacity of 30 liters is optional. eThe block mounting type is provided with a shut-off plate. ●Circuit configuration qThe basic configuration comprises a NACHICCO ) as a standard product plus external (NSPmanifold (circuit). wPiping should be arranged with a sufficient deflection between the NACHICCO and external manifold. ■ We recommend use of a hose having a normal pressure of 14 MPa {2027 psi} and a length of about 1 through 2 meters (40~80 inch). ■ The maximum peak pressure (set pressure + surge pressure) should not exceed 14 MPa {2027 psi}. ■ When the pressure rises above 14 MPa {2027 psi} , install a relief valve for surge cutting on the circuit side. qWhen a manifold block (optional) is mounted on the pump, the total weight of the block and valve should not exceed 15 kg (33.07 lbs). Type of block Weight of block Allowance for additional mounting wWhen you want to install the circuit, consult our company. ●Specifications for painting qThe inner and outer sides of the tank and motor portion are provided with melamine resin baking, and the pump portion is provided with lacquer blowing. Their color conforms to Fujikoshi standard color (Munsell NO.5B6/3). wFor the color of exterior features, consult our company. Energy saving type friendly to the earth • Options 1. Block B should be selected from among the above-mentioned five types of F1 through R2. 2. The sketch on the left shows the shape of the oil level gauge T with thermometer. Oil used: ISO VG32 or its equivalent Speed: 1800min-1 Room temperature: 29°C Motor: 0.75~2.2kW Notes: 1. For 5.0 MPa {724 psi} of a 1.10-liter tank, it should be noted that there is a big rise in oil temperature under continuous operation. In this case, we recommend use of a 20-liter tank. 2. Rise of oil temperature depends on the conditions of using an actual machine, and so may be different from the above description in some cases. (The value on the left-hand drawing represents typical characteristics under the following conditions). 34 Oil temperature rise (room temperature difference)(:) Oil temperature rise (room temperature difference)(:) Compact Variable Pump Unit eOil temperature characteristics 30 Oil used: ISO VG32 or its equivalent Oil temperature: 40±5°C Speed: 1800min-1 Measuring distance: 1 meter around the unit Standard unit Conventional NACHICCO (The value in the left-hand drawing represents typical characteristics under the following conditions). Surge cut relief valve Condition (Full cutoff: when pressure is held) Motor -- Number of poles:2.2kW-4P Voltage -- Frequency : 200V-60Hz wNoise characteristics qPower consumption Note: Adjustment of the surge cut relief valve is strictly prohibited. Handling procedure ●Precautions in startup qCheck if the tank is filled with hydraulic oil up to the specified level. Å Upper limit, Yellow mark: specified oil level (nominal capacity) ıLower limit, Red mark: minimum oil level Hydraulic oil: Based on general mineral oil, ISO VG32 or its equivalent wElectric connection should be made correctly according to the following procedure: Phases of motor side and power supply side U➞R V➞S W➞ T If electric connection is incorrect: ¡The motor pump rotates in the reverse direction without discharging oil. If the operation is continued, the pump may be damaged. ¡Use the pressure gauge mounted on the discharge side and make sure that pressure rises. eRepeat the procedure of starting and stopping the motor. Remove air from inside the pump and suction pipe. (You can remove air more quickly if you remove loads from the circuit.) ●Pressure and discharge rate adjustment procedure Pressure adjusting screw Pressure gauge Discharge rate adjusting screw Clockwise rotation Decrease Counterclockwise rotation Increase Clockwise rotation Up Counterclockwise rotation Down Note: Do not touch any screw except for the above-mentioned adjusting screw. ●Maintenance and inspection qOil temperature: Use it at the temperature from 10 to 60 °C . wHydraulic oil replacement interval: Replace hydraulic oil three months after the start of operation in the beginning. Then replace it whenever contamination has been observed or after the lapse of one year. eInspection and cleaning of tank interior and strainer: every 6 months or every 4000 hours (whichever comes first) ●Ambient temperature qTemperature: 10 to 35 °C wDo not use the mist of water soluble coolant.
