When we usually use the generator set, if the generator set cannot supply power in time, how should we deal with it? How can we make the generator power supply in time? We can do this from the following three points:
First, start the solenoid valve inspection.
When the generator set is in operation, people have summarized a set of inspection methods of “one look, two listen, three touch and four smell”. Listening at startup is a very important step. Take the USA original Cummins generator as an example, just press the start button, three seconds later, you can start. Two “clicks” can be heard within these three seconds. Once the second sound is not heard, check whether the start solenoid valve is working normally, if the electromagnetic coil is burned, the generator can not start, of course.
Second, check the battery pack.
Because the backup power supply is not often put into use, the key to whether the generator set can start normally is the maintenance of the battery. If there is a problem with the battery pack, the more common situation is; There is voltage without current, then you can hear the sound of the solenoid valve in the starting motor, but it does not move the shaft. There are three reasons why the battery pack can not stop the generator set:
1. Stop charging the battery when testing the machine, which will lead to insufficient battery power.
2. The mechanical oil pump is driven by the belt, and the amount of pump oil at the rated speed is very large, but the battery pack is insufficient, resulting in the spring plate in the shutdown valve due to the insufficient suction of the solenoid valve
And can not seal the fuel from the four oil outlet holes, resulting in no downtime.
3. Domestic batteries usually have a life of two years and are not replaced regularly.
Third, diesel oil, lubricating oil inspection.
Because the generator set is static for a long time, the various materials of the unit itself will undergo complex chemical and physical changes with oil, cooling water, diesel, air, etc., so as to “put” the unit. For this reason, attention should be paid to the problem of oil. In order to fire safety, usually put the diesel fuel tank in a closed room, due to the condensation of water in the atmosphere due to temperature changes, formed water drops attached to the inner wall of the tank, into the diesel, resulting in excessive diesel water content, such diesel into the diesel high-pressure oil pump, will rust precision coupling parts – plungers, seriously damaged the generator set. Generator lubricating oil is stored for a long time, the physical and chemical properties of lubricating oil will change, resulting in the deterioration of the lubrication state when the generator set is working, which is easy to cause damage to the generator parts.
