Notes on installing diesel generator sets:
a. If the diesel generator is used indoors, the smoke exhaust pipe must be led to the outdoors. The diameter of the smoke exhaust pipe must be larger than the diameter of the smoke outlet pipe of the silencer. There should be no more than 3 elbows in the pipeline to ensure smooth flow of smoke exhaust, and the pipe should be tilted downward by 5-10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upward, a rainproof cover must be installed.
b. If it is an indoor machine room, the installation location must be well ventilated. There should be sufficient air inlets at the generator end and good air outlets at the diesel engine end. The area of the air outlet should be at least 1.5 times larger than the area of the water tank.
c. Avoid placing items that can produce acidic, alkaline and other corrosive gases and steam near Weichai generators, and the machine room should be equipped with fire extinguishing devices.
d. When the foundation is made of concrete, a level ruler must be used to measure its level during installation to ensure that the unit is fixed on a level foundation. There should be special anti-vibration pads or anchor bolts between the unit and the foundation.
e. The two-way switch between the diesel generator and the mains power must be very reliable to prevent reverse power transmission. The wiring reliability of the two-way switch must be inspected and approved by the local power supply department.
f. The unit shell must have reliable protective grounding. For generators that require a neutral point to be directly grounded, it is strictly prohibited to use the mains grounding device to directly ground the neutral point. This must be done by professionals. It must be properly grounded and equipped with lightning protection device.
The design wind speed is 6m/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 (usually 0.6). This will give you the area of the exhaust vent. If the exhaust air needs to turn, the area needs to be increased, and the area of each 90-degree bend is increased by 15%
The air inlet volume is the exhaust air volume plus the gas volume plus the exhaust volume for heat dissipation in the computer room.
