Why water well drilling rigs idle speed erratically
The manifestation of unstable engine idling is that when idling, it is fast and slow, or there is vibration, which makes the machine stall when decelerating sharply or shifting gears. The detailed causes are analyzed as follows:
① air in the oil circuit.
② low-pressure oil supply is not smooth.
③ Idle speed stabilizer is not properly adjusted.
④ Poor atomization of the injector.
⑤ Uneven oil supply from injection pump.
⑥ Excessive wear and tear of the pins and fork heads of the governor's connecting rods.
