1. Pump Installation · Limit the deflection of the alignment between the shafts to 0.05mm TIR. · Shafts are not aligned correctly, bearing and oil seals may be damaged and noise, vibration or trouble occurred. 2. Temperature · In care the oil temperature is under 7 degree, operate the pump temporarily with the pressure lower than 20 kgf/cm² and raise the pressure after oil temperature rises. 3. Filter · Use suction filter finner than 150 mesh in suction line; In case the pump is used with hydraulic pressure ove 100 kgf/cm², use the line filter finner than 25 micron in the tank line. 4. Starting · Minimum speed at the starting should be over 950 rpm. · Lay suction line as short as possible so that suction resistance won't exceed the allowable suction resistance. · Make sure air tightness of suction line should be perfect. · Suction side and discharge side are piped with stell pipes, note that unreasonable force should not be placed on the pump. |
