The new oil hydraulic pump is poured into the tank must use oil filter filter
Hydraulic oil pump in the installation and trial run before,must be the fuel tank, pipeline, the implementation of components (such as cylinder) and the valve clean, new oilpoured into the tank must use oil filter filter, to prevent theoil pollution caused by oil drum is not clean.
1, a hydraulic oil pump oil liquid cleanliness requirements:meet the SAEJ1165 specification in ISO18/13, namely per ml of oil particles larger than 5 microns in no more than 2500 particles larger than 15 microns, no more than 80.
The viscosity of the hydraulic oil pump oil requirements: in the normal working temperature, viscosity range of 80-180SUS (16-39cSt). Viscosity plunger pump oil shall not be less than 60SUS (10cSt), starting at the lowest temperature, oil viscosity is not more than 10000SUS(2158cSt). In handling pump, earnestly pay attention not tomake the control handle pump collision.
2, the new pump in use after a week, the oil temperature not exceeding 82 degrees. The tank should be all oilfiltration time and clean the oil tank and filter, then a replacement of oil system working environment load of 3~6months according to, cleaning a tank.
3, during use is prohibited due to heating and off the fuel tank cap, but have to take other measures (such as setting the cooler).
4, on issues related to self absorption:
The pump center high to the oil surface distance of not more than 500mm, the suction pressure should be less than -125mmHg. Otherwise, cavitation occurred, causingparts damage, noise, vibration and other fault
The installation of 150 objective oil suction filter in thesuction pipe on the road, some provisions of plunger pumpproduction plant in suction installation oil filter does not allow the pipeline, but that in the oil tank Wang liquidcleanliness should be strict requirements. In the pump outlet side mounted filtering accuracy of pipeline oil filter25.
The pump speed cannot be greater than the rated speed.
Numerical the suction pipe size not less than recommended(see mounting dimensions catalog), inhalation pipe up to abending pipe joint.
The oil distribution disc such as the need to reduce theswash plate angle start, there is no guarantee that a self absorption, if users need a small flow pump, should be infull angle after the start, then change the flow variable mechanism
