或R＆O（防銹和氧化抑制劑）型液壓油的石油基礎油。
的2粘度范圍為20至400 mm / s （98?1800 SSU），
溫度范圍為0?60℃（32?140°F），兩者都必須滿足上述液壓油的使用要求。
排水管道
2.污染控制必須謹慎，以保持對工業油污染的控制，
Hydraulic Fluids Use petroleum oils such as anti-wear type hydraulic oils
or R & O (Rust and Oxidation inhibitor) type hydraulic oils equivalent to ISO VG-32 or 46.
The recommended 2 viscosity range is from 20 to 400 m m/s (98 to 1800 SSU) and temperature range is from 0 to 60°C (32 to 140°F),
both of which have to be satisfied for the use of the above hydraulic oils.
8.Drain Piping
2.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 10.
The suction port must be equipped with at least a 100 μm (150 mesh) reservoir type filter and the return line must have a line filter of
確保泵吸入口的高度距油箱的油位不到一米（3.3英尺）。
6.管道提示當使用鋼管作為吸入口或排氣口時，
從管道到泵的過大負載會產生過大的噪音。
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 (3.3 ft) from the oil level in the reservoir.
6.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 h oses. 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.
根據圖表安裝排水管道，確保泵殼內的壓力應保持在小于0.1 MPa（14.5 PSI）的正常壓力
和小于0.5 MPa（72.5 PSI）的浪涌壓力。
4.軸的對準盡可能使用柔性聯軸器，
并避免彎曲或推力產生任何應力。
無論何時擔心過載，請使用橡膠橡膠。
7.排氣管道如果泵安裝在油位上方，
吸入管路和吸入管路過濾器應位于泵位置以下，以防止吸入管路中的空氣。
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 0.1 MPa (14.5 PSI) and surge pressure of less than 0.5 MPa (72.5 PSI).
Length of piping should be less than 1 m (3.3 ft.), and the pipe end should be submerged in oil.
In case AR16 and AR22 pump, a screw-in torque of fitting is 40 to 50 Nm (354 to 443 IN.1bs.). Do not apply bending and thrust torque to the fitting.
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. ST1004-?-10?, Catalogue No.: Pub. EC3001) is recommended for this purpose
否則可能會導致故障的破壞并縮短設備的使用壽命。
請保持NAS級別10中的污染程度。
吸入口必須至少配備一個100微米（150目）的儲存器型過濾器，
回流管路必須具有10微米以下的管路濾清器。
4.Alignment of Shaft Employ a flexible coupling whenever possible, and avoid any stress from bending or thrust.
Maximum permissible misalignment is less than 0.1 mm (. 004 inches) TIR and maximum permissible misangular is less than 0.2°.
5.Suction Pressure Permissible suction pressure at inlet port of the pump is between -16 and +50 kPa (5 in.Hg Vacuum and 7 PSIG).
大允許偏差小于0.1 mm（。004英寸）TIR和大允許誤差小于0.2°。
5.吸力壓力泵入口處的允許吸入壓力在-16至+50 kPa（真空5 in.Hg和7 PSIG）之間。
液壓油使用與ISO VG-32或46相當的耐磨型液壓油
3.安裝安裝泵時，灌裝口應向上定位。
under 10 μm. 3.Mounting When installing the pump the filling port should be positioned upwards.
對于吸入口的管道，請使用與使用規定管道法蘭相同直徑的管道。
