Precautions for Acceptance Diesel Generators

Mar. 11, 2022

Diesel generators are widely used in emergency backup power supply in hotels, hospitals, shopping malls, real estate and other industries, and users have higher and higher requirements for the quality and performance of unit equipment. How to prolong the service life of the generator and let the generator exert the maximum energy, the early installation and acceptance of the diesel generator is very important. Today, we will explain in detail several aspects that need to be paid attention to in the acceptance process of diesel generators.

The diesel generator casing must have a reliable protective grounding. For generators that need to have a neutral point directly grounded, the neutral grounding must be carried out by professionals, and a lightning protection device must be configured. ground directly.

The surroundings of the diesel generator installation site should be kept clean, and items that can generate acid, alkali and other corrosive gases and steam should be avoided. Where possible, fire extinguishing devices should be provided.

The diesel generator installation site should be well ventilated, the generator end should have sufficient air inlets, and the diesel generator end should have good air outlets. The area of the air outlet should be more than 1.5 times larger than the area of the water tank; the air inlet is not smooth or does not meet the requirements, and less air enters the cylinder, which will cause insufficient fuel in the cylinder, resulting in carbon deposits, which will affect the load capacity of the diesel generator. ; Similarly, the exhaust pipe does not meet the requirements, and the oxygen content of the air in the engine room is reduced, which will also cause insufficient fuel in the cylinder, resulting in carbon deposition, which affects the load-carrying capacity of the diesel generator.

The two-way switch between the diesel generator and the mains must be very reliable to prevent reverse power transmission. The wiring reliability of the two-way switch needs to be verified by the local power supply department.

If the diesel generator is used indoors, the exhaust pipe must be led to the outside, and the diameter of the pipe must be greater than or equal to the diameter of the exhaust pipe of the muffler. The pipe is inclined downward by 5-10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upward, a rain cover must be installed. In order to improve the output power of the diesel generator, under the condition of a certain cylinder capacity and number, only by forcing more air into the cylinder to fully burn the fuel in the cylinder can the average effective pressure of the unit be increased. Once the exhaust gas is not smooth or the exhaust gas speed does not meet the requirements, the air entering the cylinder will decrease, which will cause the diesel generator's load-carrying capacity to decrease.

When the diesel generator foundation is made of concrete, the horizontality must be measured with a level ruler during installation, so that the unit can be fixed on a horizontal foundation. There should be special shock-proof pads or foot bolts between the unit and the foundation.

Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
