Particular attention should be paid to the use of the diesel generator. Improper use will cause damage to the generator. Repairing it is a waste of labor and financial resources, and is completely unprofitable when using a generator. generator, all you need is With a little attention, you can extend the life of your generator and reduce the frequency of generator repairs.
A diesel generator is an independent power generation device that primarily provides backup power in the event of a power outage. In fact, the unit is in a standby state most of the time and there are relatively few opportunities to actually put it into operation. Usually, it is mainly tested and lacks relatively comprehensive detection and maintenance methods. But this backup power source is essential.
How did youensure that the power supply can be supplied in time in an emergency, the operation is safe and reliable, and the machine can be stopped immediately after the power failure even when the power supply is rarely used.
First, check the battery. Since the emergency power supply is not often used, the key to whether the diesel generator can start normally lies in battery maintenance. If there is a problem with the battery, a common situation is: there is voltage but no current. At this time, you can hear the sound of the starter solenoid valve closing, but the coupling shaft cannot be driven.
There are three reasons why the machine cannot be stopped due to problems with the battery:
Stopping charging the battery during testing will result in insufficient battery charge .
The oil pumpmechanical is driven by a belt. The pump oil volume at rated speed is very large. However, the battery does not provide enough power. The shutoff valve cannot seal flow on all four sides due to insufficient suction of the solenoid valve during shutdown. Fuel sprayed from the oil outlet hole prevented the engine from stopping.
Home batteries generally have a lifespan of two years and are not replaced regularly.
Second, start inspecting the solenoid valve. When the generator is running, people have summarized a set of inspection methods: "one look, two listens, three touches and four smells". Listening at startup is a very important step. Taking the generator as an example, you just need to press the start button and it will start after three seconds. Two “clicks” can be heard during these three seconds. AOnce the second sound is no longer audible, check whether the start solenoid valve is operating normally. If the solenoid coil is blown, the generator will of course not be able to start.
Third, check the diesel and lubricating oil. Since the unit remains in a static state for a long time, the different materials of the unit itself will undergo complex chemical and physical changes with oil, cooling water, diesel, air, etc. , thus “unloading” the unit. This is why attention should be paid to the oil issue. For fire safety reasons, diesel fuel tanks are usually placed in a closed room. Since water vapor in the atmosphere condenses due to temperature changes, water droplets form and cling to the inner wall of the fuel tank and flow into the diesel fuel, thus causing water. The content of the cdiesel fuel exceeds the standard. Such diesel fuel entering the high pressure oil pump of the diesel engine will corrode the precision coupling part - the piston, seriously damaging the unit. Generator lubricating oil has a shelf life. When stored for a long time, the physical and chemical properties of the lubricating oil change, causing the lubrication conditions to deteriorate when the unit is operating and easily damaging the generator parts.
Many companies do not know how to produce diesel. Generator maintenance often causes operating errors, resulting in damage to the generator, which shortens the life of the generator and increases the costs to a certain extent. business costs.
