The diesel generators are all provided as emergency backup power supply after a power outage, and the unit is in standby standby for most of the time. Once the power is cut off, the unit is required to “get up and move”. Otherwise the standby unit will lose its meaning! Practice has proved that strengthening routine maintenance is the most economical and effective method. Because the unit is in a static state for a long time, the various materials of the unit itself will undergo complicated chemical and physical changes with the oil, cooling water, diesel oil, air, etc., and thus the unit will be “disposed”.
Nearly 30% of the failures in the unit's failure to initiate repairs are: The unit has started a battery failure. For example, the battery is unmaintained for a long time, the electrolyte is not replenished in time after the water evaporates, the battery charger is not configured, and the battery has a long time. After the natural discharge, the power is reduced; or the charger to be used needs manual periodical equalization/floating charge switching, and the battery power does not meet the requirement due to negligence of the switching operation.
In addition, during daily inspections of diesel generators, it is difficult for non-professionals to find small traces, which usually lead to major failure of the unit and render it unusable. Wait until the emergency unit needs to start the unit to find out that the equipment cannot operate. Wait until the repair and maintenance personnel arrive at the site to judge the fault, determine the maintenance plan, and then begin to purchase the spare parts and repair it to the end. At least 10 days or a half month later, the loss caused has no result. Recall.
At present, many users of diesel generator sets have to hand over the units to professionals for regular inspections and maintenance to ensure that they can be used in emergencies. In particular, there are some important units and departments, such as broadcasting and television systems, hospitals, and enterprises that can not cut off the power of the core devices, and many chemical companies that have relatively high requirements for fire protection.
The purpose of purchasing standby power generation equipment is to prevent it from happening, and to put it plainly that it is necessary to be able to operate the equipment and to be able to solve the urgent need. Otherwise, enterprises will spend money to buy these equipment and become vase-like furnishings.
The importance of proper maintenance and inspection of diesel generator sets is self-evident, and proper inspection and maintenance requires personnel with professional knowledge and extensive experience to implement. Many users' operators have undergone simple training. However, because the training is all about some superficial operational knowledge, and there is no experience, for the discovery of hidden dangers and the advance anticipation of equipment failures, these are generally impossible for the operators to do. Therefore, professional maintenance and inspection of diesel generator sets is correct.
