Speed failure is very common in the use of diesel generator sets, and once a speed failure, it is very easy to cause damage to the generator set, which not only seriously affects the efficiency of the generator and causes serious waste, but also causes serious electrical accidents, so prevent speed It is a must-do for the daily maintenance of the generator set; this quark motor collects and sorts out the following three routine items to prevent runaway:

1. Ensure that the machine oil and water are free from impurities and deterioration.

In particular, the oil level of the high-pressure fuel injection pump should be strictly controlled at the required position-the center line of the screw plug under the casing of the governor. The liquid level is too high and the viscosity is too high-the resistance is increased, which limits the governor's governing effect; the liquid level is too low or there is no liquid level-causing the parts in the governor to wear out, and the governing function decreases or loses. As a result, a speed accident occurs. Therefore, we must resolutely prevent the occurrence of no or insufficient lubricant in the governor.

2. Check the bolts of each part of the machine to ensure that they are intact and not loose.

Especially to prevent the screw plug at the lower part of the governor shell from loosening or falling off, resulting in loss of lubricating oil in the governor, abrasion of parts in the governor, rack jam, bearing damage, etc., losing the function of speed control and causing runaway.

3. Continuously improve the safety awareness and proficient operation skills of employees.

Understand the basic situation of the equipment used, use and operate the equipment in strict accordance with the safety operating procedures, and be able to accurately judge and correct the common faults that may occur during use.

It is particularly pointed out here that after a flying car accident, it is absolutely not allowed to remove the load, otherwise the speed will increase sharply and cause greater danger, and it is never allowed to directly block the air inlet by hand.
