Diesel generator set installation precautions
Whether it is a general generator set, a generator set, a generator set or a diesel generator set, whether it is a rented generator or a purchased diesel generator, the prices; are very high. So how to extend the life of the generator and maximize its efficiency is a big problem. This article mentions some issues that should be paid attention to when installing generators, based on Renren and Mechanical's long experience in solving production and customer life problems.
1. The installation site must be well ventilated, with sufficient air inlets on the generator side and good air outlets on the diesel engine side. The air outlet area should be more than 1.5 times larger than the water tank area.
2. The area around the installation site must be maintainede clean and objects that may generate corrosive gases and vapors such as acids and alkalis should be avoided nearby. Fire extinguishing devices should be equipped wherever possible.
3. When used indoors, the smoke exhaust pipe must be directed outside. The diameter of the pipe must be ≥ the diameter of the silencer smoke outlet pipe. the pipe should not exceed 3 to ensure that the exhaust pipe is To ensure smooth flow of smoke, the pipe should be tilted downward 5-10 degrees to avoid rainwater injection if the exhaust pipe is installed vertically upwards, a rain cover must be installed; .
4. When the foundation is concrete, flatness should be measured with a level ruler during installation to ensure the unit is secured to a level foundation. There must be anti-special vibration or anchor bolts between the unit and the foundation.
5. The unit shell must have reliable protective earthing. For generators that require a neutral point to be directly grounded, neutral grounding should be done by professionals and equipped with lightning protection devices. to use commercial power supply. The grounding device leads the neutral point to be directly grounded.
6. The two-way switch between generator and mains must be very reliable to prevent reverse power transmission. The reliability of the two-way switch wiring should be inspected and confirmed by the local power supply department.
The need to install an exhaust shaft mainly depends on your requirements in terms of noise. The noise of a typical generator is 102 decibels. In order to avoiddisturb others, noise reduction treatment is usually necessary. Noise reduction treatment generally involves installing air inlet and exhaust shafts in the shafts; The exhaust pipe is equipped with a heavy-duty silencer, and the smoke pipe is discharged out of the building and raised to the top of the building for discharge. In this way, the noise can generally reach less than 65 decibels. Smoke extraction shafts cannot be installed. Unless the smoke shaft is designed before the construction of high-rise buildings.
