The diesel generator group is the provider of the emergency standby power supply after the power failure of the city. Most of the time units are in standby standby state. Once the power outages, the unit is required to be "moved and available". Otherwise the spare unit will lose the meaning! Practice has proved that strengthening daily maintenance is the most economical and effective way. Because the unit is in a static state for a long time, the various materials of the unit itself will have complicated chemical and physical changes with oil, cooling water, diesel, air and so on, so that the unit will be "put".
In the actual work, there are many serious failures in the unit failure reporting that our company has received, often due to small maintenance negligence and lack of professional inspection. For example, the diesel oil tank will be condensing because of the temperature change in the atmosphere, and the formation of water droplets is attached to the inner wall of the tank and into the diesel. The water content of the diesel is exceeding the standard, so the diesel oil enters the high pressure oil pump of the engine, and it will rust the precision coupling parts - plunger and seriously damage the unit. Regular maintenance can be avoided.
Nearly 30% of the failure causes in the unit's inability to start repair are the failure of the unit starting battery, for example, the battery is unmaintained for a long time, the electrolyte can not be replenished in time after the evaporation of the electrolyte, and the starting battery charger is not configured; the battery can be reduced after a long time of natural discharge; or the charger needs to be fixed on a regular basis. Due to inadvertent switching operation, the battery can not meet the requirements.
In addition to the daily inspection of diesel generating sets, it is difficult to find some tiny traces due to non professional personnel, which usually leads to a major failure of the unit and can not be used. When an emergency is needed to start the unit, it can not be found that the equipment can not run. When the repair and maintenance personnel arrive to judge the fault, determine the maintenance plan, and then start the purchase of the spare parts maintenance to the end, at least 10 days or half a month ago, the loss has been irreparable.
At present, a lot of users using diesel generator set the unit to the professional staff regularly to check and maintain, in order to ensure that the equipment can be used in emergency conditions. In particular, some important units and departments, such as the radio and television system, the hospital, the core device can not be power cut enterprises and many chemical enterprises with higher fire requirements.
The purpose of purchasing the standby power generation equipment is to prevent it. It is in white that the equipment can run when it is needed, and it can solve the urgent problem. Otherwise, the enterprise will spend the money to buy the equipment as the vase.
It is self-evident that the correct maintenance and inspection of the diesel generator set is self-evident, and the correct inspection and maintenance requires professional knowledge and rich experience of the personnel to implement, many user operators have been trained simply, but because the training is a few shallow operation common sense, and There is no experience outside, for hidden dangers and equipment failure to detect in advance, these are the general operators can not do. Therefore, it is correct for professionals to carry out professional maintenance and inspection of diesel generating sets.
