As there are no dedicated instruments for loading test runs, it is impossible to detect whether the output rated power and load-carrying capacity of the project can meet the design requirements after its completion, which directly affects the project acceptance. Although the environmental noise in some unit rooms has been reduced after the installation of noise reduction equipment, it still has a certain impact on the output power of the units. It is impossible to detect exactly how much output power of the units has been lost, whether the quality of the noise reduction project meets the contract requirements according to the original design, and how much reasonable power loss of the units is guaranteed.
How to extend the service life of a generator and ensure it operates at its rated energy? The initial installation of a diesel generator set is of great significance. Here are some installation precautions:
1. The installation site should have good ventilation. There should be sufficient air inlets at the generator end and good air outlets at the diesel generator set end. The area of the air outlet should be more than 1.5 times that of the water tank. If the air inlet is not unobstructed or does not meet the requirements, less air will enter the cylinder. This will cause insufficient fuel in the cylinder, resulting in carbon deposits and affecting the load-carrying capacity of the diesel generator set. If the exhaust pipe does not meet the requirements, the oxygen content in the air inside the machine room will decrease, which will also cause insufficient fuel in the cylinder, resulting in carbon deposits and affecting the load-carrying capacity of the diesel generator set.
2. The area around the installation site should be kept clean, and items that can produce acidic, alkaline or other corrosive gases and vapors should not be placed nearby. Fire extinguishing devices should be installed where conditions permit.
3. When used indoors, the exhaust pipe must be led outdoors. The pipe diameter must be greater than or equal to the diameter of the exhaust pipe of the muffler. The number of elbows connected to the pipe should not exceed three to ensure smooth exhaust. The pipe should be inclined downward by 5 to 10 degrees to prevent rainwater from entering. If the exhaust pipe is installed vertically upwards, a rain cover must be added. To enhance the output power of diesel generator sets, under the condition that the cylinder capacity and number are fixed, only by forcing more air into the cylinder to ensure the complete combustion of the fuel inside can the average effective pressure of the unit be increased. Currently, diesel generator sets all adopt turbochargers, which imposes relatively strict requirements on the exhaust of diesel generator sets. Once the exhaust is not smooth or the exhaust gas speed does not meet the requirements, the amount of air entering the cylinder will decrease, which will cause the load-carrying capacity of the diesel generator set to decline.
4. When the foundation is made of concrete, a level must be used to measure its levelness during installation to ensure that the unit is fixed on a level foundation. There should be dedicated shock-absorbing pads or anchor bolts between the unit and the foundation.
5. The casing of the unit must have reliable protective grounding. For generators that require direct grounding of the neutral point, the neutral grounding must be carried out by professionals and lightning protection devices must be configured. It is strictly prohibited to use the grounding device of the municipal power supply for direct grounding of the neutral point.
6. The bidirectional switch between the generator and the municipal power supply must be highly reliable to prevent reverse power transmission. The wiring reliability of the bidirectional switch needs to be inspected and confirmed by the local power supply department.
7. The wiring of the starting battery must be firm.
In conclusion, after the diesel generator set is installed, it is necessary to conduct acceptance tests, mainly including load-carrying capacity tests and electrical characteristic tests, to determine whether it can meet the power level required in the initial tender or the capacity requirements designed at the beginning. This can help us have a clear understanding and prevent the occurrence of safety accidents.
