1. The location of the equipment should have smooth ventilation, there should be sufficient air inlets at the generator end, and there should be air outlets at the diesel engine end. The air outlet area should be more than 1.5 times larger than the water tank area (for reference only: (Fujian Yanan diesel generator) Yaxiaonan will answer for you)
2 . be kept clean to avoid placing near objects that may generate corrosive gases and vapors such as acids and alkalis. Fire-fighting equipment should be equipped if possible;
3. When used indoors, the smoke exhaust pipe must be directed outside. The diameter of the pipe must be ≥ the diameter of the smoke outlet pipe. the silent. The diameter of the connected pipe must be There must not be more than 3 elbows to ensure smooth flow of the smoke evacuation, and the tuyau should be tilted downward 5-10 degrees to prevent rainwater from entering if the exhaust pipe is installed; vertically upwards, it is necessary to install a rain cover;
4. When concrete is used as a foundation, a level ruler should be used to measure its level during installation to ensure the unit is secured to a support. level foundation. There must be special anti-vibration pads or anchor bolts between the unit and the foundation;
5. The unit shell must have reliable protective grounding. For generators that require a neutral point to be directly grounded, this is the case. The necessary professionals must carry out the neutral grounding and be equipped with lightning protection equipment. It is strictly prohibited to use mains grounding equipment to directly ground the neutral point ;
6. the mains must be very reliable to prevent power transmission. The reliability of the two-way switch wiring must be inspected and certified by the local power supply department.
Inlet design of diesel generator set
The design wind speed is 6 m/s.
According to the exhaust volume of different units divided by the wind speed, the effective exhaust area is divided by the space coefficient of the silencer group (generally 0.6). This will give you the surface area of the air outlet. If the exhaust air is to rotate, the surface area must be increased and the surface area of each 90 degree elbow is increased by 15%
The air inlet volume is the volume of air exhausted plus the gas volume plus the exhaust volume for heat dissipation in the computer room.

1. Concerning the well of the smoke evacuation pipe ( mandatory), the manufacturer requires a minimum clearance: 800x800 mm for a generator; 1200 x 1200 mm for two generators. Increase appropriately when conditions permit.
2. Regarding the clearance size of the spray dusting room (suitable for installation): 1800 x 2000 mm when a generator is used; 1800 x 2800 mm when two generators are used together.
