1 if a Komatsu PC200-8 is working, the micro operation performance is poor. After measurement, the main overflow pressure is 350kg/cm2, the LS pressure difference joystick is 35 kg/cm2 at the middle position, the speed HI walks empty, the full throttle, and the control lever half stroke, 26kg/cm2. can restore the machine by adjusting the PC valve.
2 suppose that a WA380-3 is driving in the four gear. Suddenly the H-L of the car is damaged by solenoid valve, then the vehicle should turn into a forward gear.
The working order of the 3 one four stroke engine is 1-5-3-6-2-4. Assuming that the angle of work interval and the overlap angle are ignored, the stroke of the 3 cylinder is inhaled when the 1 cylinder is in the compression stroke.
4 Komatsu PC200-8 crawler tightness is 10~30 cm
5 Komatsu excavator 107 EFI Engine:
Its fuel injection time and fuel injection time are controlled by the engine controller.
The low pressure of the public tank may cause the engine to fail to start.
The safety valve on the public sump will not open under normal condition.
6 the type HPV105+105 of a hydraulic pump, whose pressure is 320 kg/cm2. when the engine speed is 2000rpm, if the trace leakage is ignored, its maximum absorption power is about equal to 299HP.
7 the main function of the LS valve of the Komatsu excavator is to perceive the operator's operation stroke and adjust the pump flow.
8 when Komatsu PC200-8 measures the deviation, it is necessary to measure the offset of the excavator traveling at 20 meters.
9 the main function of designing the regeneration loop is to improve the working speed.
10 the main part of the accumulator inside the broken hammer shell is nitrogen.
11 the main pump pressure sensor of Komatsu PC200-8 hydraulic excavator has an input voltage of 5V. The larger the output voltage, the greater the pressure of the main pump.
12 when replacing the air-conditioning compressor, it is necessary to add the refrigerating oil again.
13 the PC valve of Komatsu PC200-8 is built in the servo piston small end, the area ratio of the size and end is 2:1..
