Frequently Asked Questions About Diesel Generators

Diesel generators are highly efficient power generation devices, but many people lack in-depth knowledge about them. As a professional diesel generator manufacturer, Guangxi Dingbo Diesel Generator will introduce this equipment to you through a series of Q&A, covering installation, maintenance, selection and other key aspects to help you fully understand diesel generators.

1. When installing a new generator set, the customer service staff will require the customer to install the exhaust pipe at a downward angle of 5-10 degrees. Why is this?

The reason for this requirement is that the designers have considered that this can prevent rainwater from entering the exhaust pipe. As we all know, water entering the exhaust pipe will have serious consequences, so this is a measure to prevent major accidents.

2. The diesel engine part of the diesel generator set is equipped with a manual oil pump and an exhaust bolt. What are their functions?

The combination of these two can be used to expel air from the fuel pipe before starting the engine.

3. Generally, manufacturers will require users to choose a site with smooth air flow for the installation and use of the generator set. Why is this?

When a diesel generator set is in operation, the output power of the diesel engine will be affected by the quantity and quality of the inhaled air. At the same time, the engine also needs sufficient air for cooling, so smooth air circulation is a necessary basic condition.

4. When installing the generator set, the manufacturer often does not tighten the oil filter, diesel filter and oil-water separator very tightly, just to the extent that there is no oil leakage. Will there be any danger in the later use?

The answer is no. On the contrary, tightening them too tightly will be dangerous. If tightened too much, the sealing ring will undergo thermal expansion under the action of oil soaking and body heating, which will generate great stress. This will cause damage to the filter shell or separator shell, and may also cause damage to the body nut, which cannot be repaired.

5. Why do new generator sets need to change oil and filters after being used for a period of time?

The initial use period of a new generator set is actually a running-in process. During this process, some impurities will inevitably enter the oil pan, which will cause physical or chemical changes to the oil and filter. Therefore, timely replacement is a responsible act for the later use of the generator set, and it can also make the later use more smooth.

6. There are more and more brands of domestic diesel engines. How to distinguish between genuine and fake ones when purchasing?

This is exactly the knowledge that the majority of consumers should popularize. When purchasing domestic diesel generator sets, we should first check their "ID cards", namely the factory certificate and product certificate. The certificate must be accompanied by the nameplate number, engine body number and oil pump nameplate. If the certificate is missing or the three major numbers are incomplete or incorrect, it is recommended that you first verify with the manufacturer, as there is a high possibility of forgery.

7. How to choose the oil for diesel generator sets?

It is recommended that you choose the oil recommended by professional manufacturers. This is because oil is equivalent to the blood of the engine, and its position is very important. If you randomly choose unqualified oil products, it will inevitably cause various serious failures during the use of the generator set engine, even the scrapping of the whole machine, so you need to be careful.

8. Is 400V the standard output voltage of the generator set?

This is correct. Due to the voltage drop loss in the line after output, its standard voltage is 400V instead of the commonly used 380V.

9. What are the main applications of diesel generator sets?

The principle of the generator set is to generate electricity through the combustion of diesel and energy conversion. It can be used as a self-provided power supply, standby power supply, alternative power supply, mobile power supply and fire-fighting power supply.

10. How is the automation level of diesel generator sets?

Existing generator sets are available in several types: manual, self-starting, self-starting with automatic mains transfer cabinet, and long-distance three remote (remote control, remote measurement, remote monitoring). Overall, the automation level is relatively high.
