TESTING AND ADJUSTING STANDARD VALUE TABLE FOR CHASSIS PC130-7 20-11 (1) Model name PC130-7 Cate- gory Item Measurement condition Unit Standard value Permissible value Pump performance Hydraulic pump performance • PC-EPC current: 400 mA • Pump speed: 2,000 rpm Test pump discharge Lower limit of Standard discharge Check point pressure discharge (l/min) (MPa{kg/cm2}) (l/min) Q Q Any point P (See graph) (See graph) a Avoid measuring near a broken point of the graph, since the error becomes large at that point.
a When measuring without removing the pump from the machine, if the engine speed cannot be set to the speci- fied speed with the fuel control dial, calculate the pump discharge pressure at the specified speed from the engine speed and pump discharge at the time of measurement.
