Why do excavators have problems with slow motion?

What is the reason for the engine speed out of control of the excavator?

  1. Too much air filter oil in inertial oil bath. It is sucked into the cylinder and burned. It’s the same as increasing the fuel supply, but speeding up and accelerating.
  2. A bent or installed oil plug may cause the fuel injection pump plunger to turn and lose the governor bracket. In particular, the multi-cylinder oil pump is in the no-load state, and the fuel supply cannot be changed, resulting in a fault state.
  3. The transmission sleeve of the governor of the single fuel injection pump of the single-cylinder diesel engine is stuck, causing the speed regulation to fail.
  4. Part of the oil inlet hole and the oil return hole of the plunger sleeve of the fuel injection pump are on the same plane. If the screw on the plunger sleeve is too long and blocks the oil return hole, the oil quality will deteriorate and the oil supply will start. Surges can also cause acceleration.
  5. The fuel pump adjustment gear is stuck in the fuel supply position, or the gear rack is disengaged from the governor lever and out of control.
  6. Excessive lubrication of the governor casing will hinder the opening of the speed regulation and affect the speed regulation.
How to preserve the value of excavators
  1. Maintain the parts on time and keep them in their original condition to ensure the service life of the excavator. More inspection, more maintenance, less maintenance, less replacement parts. The original parts of the car should be kept as much as possible, and the wearing parts should be replaced in time to avoid major failures caused by major failures.

  2. Keep your mini excavator clean inside and out. The grease will overflow when refueling, and the grease will be squeezed out when lubricating. Wipe it in time to avoid external paint corrosion.

  3. Experienced operators usually refer to driving habits, do not dry the car, maintain the original superior performance of the machine, and prolong the service life. In winter, the car must be heated at a low temperature, and it can only work when the oil temperature is normal. In summer, working at high temperature for a long time may not work immediately, especially the turbocharger.

  4. A newly purchased excavator can be used for many years. Only by creating more use value can we talk about value preservation. After all, use value is much greater than surplus value.
