There is too much air filter oil in the inertia oil bath. It is drawn into the cylinder and burned. This is the same as increasing the fuel supply, but accelerating and speeding up.
Bending or oil plug mounting may cause the injection pump plunger to rotate and lose the speed control bracket. In particular, a multi-cylinder fuel pump is at no load and cannot change the fuel supply and cause a fault condition.
Single-cylinder diesel engine single injection pump governor drive sleeve jammed, resulting in speed regulation failure.
Injector pump plunger sleeve part of the oil inlet hole and return hole in the same plane. If the screw on the plunger sleeve is too long, blocking the return hole, it will make the oil quality worse and start to supply oil. Surge can also cause acceleration.
The fuel pump regulating gear is stuck in the oil supply position, or the rack is disconnected from the governor lever out of control.
Excessive lubrication of the governor housing will prevent the speed regulation from opening and affect the speed regulation.
What are the ways to preserve the value of excavators?
Maintain parts on time and in pristine condition to ensure the life of your excavator. More inspection, more maintenance, less maintenance, less replacement parts. Keep the original parts of the car as much as possible, and replace wearing parts in time to avoid major breakdowns caused by major faults.
Keep the mini excavator clean inside and outside. Grease will spill out when refueling, and grease will be squeezed out when lubricating. Wipe in time to avoid external paint corrosion.
Experienced operators, usually referring to driving habits, do not dry the car to maintain the original superior performance of the machine and extend the service life. In winter, the car must be heated at low temperature and can only work when the oil temperature is normal. In summer, it may not work immediately, especially the turbocharger, when it works in high temperature for a long time.
A newly bought excavator can be used for many years. Only when more use value is created can we talk about preserving the value. After all, the use value is much greater than the residual value.
