How are hydraulics used in a Komatsu excavator?
How are hydraulics used in a Komatsu excavator?
The hydraulic pump is used as the power source for the hydraulic system, and its operating conditions affect the degree of system fever. Komatsu excavators repair the electrical parts and main components of engines, hydraulics, height-controlled engines and hydraulics, all developed and produced by Komatsu itself.
How can a fault be eliminated in a Komatsu?
During the rotation of the damper damper, a large amount of heat (Heat) is generated and transmitted to the hydraulic pump, causing the system to heat up. At this point, the fault can be eliminated by draining the shock absorber fluid to the standard oil level.
Where is the oil return valve in Komatsu?
From the hydraulic system (system diagram) (yuán lǐ) diagram can be seen, hydraulic system oil filter (Filter) check valve and hydraulic oil (Hydraulic) radiator (reducing the heat generated when the equipment is running) and connected to the oil return At the outlet of the filter element (see PC200-7 Hydraulic System Schematic).
What causes a Komatsu water pump to heat up?
If the end face of the pump gear wears a lot or the tooth gap is large, the internal leakage increases, which will cause the pump to heat up and affect the normal operation of the main pump. The overflow valve pressure is too high or too low, which will cause the hydraulic system to heat up.

What causes a PC200 excavator to heat up faster?
For example, the main pump of the PC200 excavator is a plunger pump. If the matching plate between the pump and the cylinder, the sliding shoe, the swash plate and the plunger cylinder wear a large amount (a basic type of component failure) is large, which often results in The hydraulic pump heats up faster.
What does The PC200 excavator pilot control pump do?
The PC200 excavator pilot control pump is a gear pump. Its function is to provide the system with operation control pressure oil and adjust the displacement of the main pump according to the load requirements.
When to run an excavator at full throttle?
In special situations (such as in pond digging), I crank it up to full throttle because pond bottom moss is impossibly tough to tear. Another reason to avoid running the engine too slow (1/3 throttle or below) is that the engine will have to put in more fuel per stroke to get the same amount of work done than at a higher RPM.

What should I do if my Komatsu heat sink is not working?
In addition to the intuitive judgment of the former two, it is also known from the temperature difference between the upper and lower tubes of the radiator that the heat sink should be cleaned and the fan belt should be tightened.
