How to manage the safety of daily use of diesel generator sets?

Diesel generator set is an independent non-continuous operation power generation equipment, and its main function is to provide emergency power in the event of a power outage. In fact, diesel generator sets are in standby state most of the time, and there are fewer opportunities to actually put them into use, so there is a lack of more complete detection and maintenance methods. However, emergency backup power equipment such as diesel generator sets is indispensable and can play an important role in critical moments. How to ensure that diesel generator sets can be powered on in time and operate safely and reliably in an emergency on the premise of less startup at ordinary times, and can immediately shut down after completing emergency tasks after a power outage. It is necessary to have good maintenance knowledge of diesel generator sets.

(1) Check the battery pack

As a backup power source, diesel generator sets are not often put into use on a daily basis. The normal starting of diesel generator sets and the maintenance of batteries are the key determinants. When there is a problem with the battery pack, there will be a "voltage but no current" fault. When this happens, you can hear the suction sound of the solenoid valve in the starter motor, but the coupling shaft is not driven. There is a problem with the battery pack and it is impossible to stop the machine because the battery is insufficiently charged due to the method of stopping the charging of the battery during the test machine. At the same time, if the mechanical oil pump is driven by a belt, the pump oil volume at the rated speed is large, but the battery pack power supply is insufficient, which will cause the spring plate in the shut-off valve to be blocked due to insufficient suction force of the solenoid valve during shutdown. The fuel sprayed out of the hole can not stop the machine. There is also a situation that may be overlooked. The domestic battery life is short, about two years. This will also happen if you forget to replace it regularly.

(2) Check the start solenoid valve

When the diesel generator set is running, it can be checked by looking, listening, touching and smelling. Take the original diesel generator set as an example, press the start button for three seconds, and then it can be started by listening. During the three-second start-up process, two clicks are normally audible. If only the first sound is heard and the second sound is not heard, it is necessary to check whether the start solenoid valve is working properly.

(3) Manage diesel oil and lubricating oil

Because the diesel generator set is static for a long time, the various materials of the generator set will undergo complex chemical and physical changes with oil, cooling water, diesel oil, air, etc., which will cause hidden but continuous damage to the diesel generator set. We can maintain and maintain diesel generator sets from two aspects of diesel and lubricating oil management.

Pay attention to the storage location of diesel oil: the diesel fuel tank should be placed in a closed room, on the one hand for the consideration of the fire safety system, on the other hand, to ensure that the diesel oil will not deteriorate. Because the water vapor in the air will condense due to the change of temperature, the water droplets gathered together after condensation will be attached to the inner wall of the fuel tank. If it flows into the diesel oil, the water content of the diesel oil will exceed the standard, and the diesel oil with excessive water content will enter the high-pressure oil pump of the diesel engine. , it will gradually corrode the components in the unit. This corrosion will have an important impact on the performance of the precision coupling parts. If the impact is serious, the entire unit will be damaged.
