2 / AR-FR1 Instructions Instructions 1.Hydraulic Fluids Use petroleum base oils such as anti-wear type hydraulic oils or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG- or. The recommended viscosity range is from to mm /s (9 to SSU) and temperature range is from to ( to 1 ), both of which have to be satisfied for the use of the above hydraulic oils..control of Contamination Due caution must be paid to maintaining control over contamination of the operating oil which can otherwise lead to breakdowns and shorten the life of the unit. Please maintain the degree of contamination within NAS Grade. The suction port must be equipped with at least a µm (15 mesh) reservoir type filter and the return line must have a line filter of under µm..mounting When installing the pump the filling port should be positioned upwards..alignment of Shaft Employ a flexible coupling whenever possible, and avoid any stress from bending or thrust. Maximum permissible misalignment is less than.1 mm (. inches) TIR and maximum permissible misangular is less than.? 5.Suction Permissible suction pressure at inlet port of the pump is between -1 and +5 kpa (5 in.hg Vacuum and 7 PSIG). For piping to the suction port, use the pipes of the same diametre as that of the specified pipe flange to be used. Make sure that the height of the pump suction port is within one metre (. ft) from the oil level in the reservoir..hints on Piping When using steel pipes for the suction or discharge ports, excessive load from the piping to the pump generates excessive noise. Whenever there is fear of excessive load, please use rubber hoses. 7.Suction Piping In case the pump is installed above the oil level, the suction piping and suction line filter should be located lower than the pump position to prevent air in the suction line..drain Piping Install drain piping according to the chart and ensure that pressure within the pump housing should be maintained at a normal pressure of less than.1 MPa ( PSI) and surge pressure of less than.5 MPa (7.5 PSI). Length of piping should be less than 1 m (. ft.), and the pipe end should be submerged in oil. In case and AR pump, a screw-in torque of fitting is to 5 Nm (5 to IN.1bs.). Do not apply bending and thrust torque to the fitting. Model, AR [Recommended Drain Piping Size] Fitting Size / [Inside Dia..5 mm (. in.) or more] Inside Dia. of Pipe mm (.9 in.) 9.Bleeding Air It may be necessary to bleed air from pump case and outlet line to remove causes of vibration. An air bleed valve (Model No. ST- -, Catalogue No.: Pub. EC- 1) is recommended for this purpose. No.
3 / AR-FR1 Instructions.Starting Before first staring, fill pump case with clean operating oil via the fill port. In order to avoid air blockage when first starting, adjust the control valves so that the discharged oil from the pump is returned direct to the tank or the actuator moves in a free load.
