1. The installation site must be well ventilated. There should be sufficient air inlets at the generator end and good air outlets at the diesel engine end. The air outlet area should be more than 1.5 times larger than the water tank area.
2. The area around the installation site should be kept clean, and items that can produce corrosive gases and vapors such as acid and alkaline should be avoided nearby. Fire extinguishing devices should be equipped where possible.
3.
If used indoors, the
smoke exhaust pipe
must be connected to the outdoors, and the pipe diameter must be ≥
p>
The diameter of the smoke outlet pipe of the silencer
should not have more than 3 elbows in the connected pipe to ensure smooth smoke exhaust, and the pipe should be tilted downward 5--10 degree to avoid rainwater injection; if the
exhaust pipe
is installed vertically upward, a
rain cover must be installed
.
4. When the foundation is made of concrete, the levelness must be measured with a water
square ruler
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.
5. The casing of the generator set must have reliable
protective grounding
. For generators that need to have a neutral point directly grounded, they must be connected by professionals.
Neutral point grounding
and equipped with
lightning protection device
, use of mains power is strictly prohibited
< p>Grounding deviceThe neutral point is directly grounded.
6.
The two-way switch between the generator and the mains 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.
7.
Starting
The wiring of the battery
must be firm.
There are two cooling methods for diesel generator sets: air cooling and water cooling.
1. Air cooling
The air cooling method uses air as the cooling medium to transfer the heat from the heated parts of the diesel engine. This cooling method consists of Composed of cooling fan and guide cover.
In order to increase the heat dissipation neps, many corrugated fins are usually cast on the outer walls of the cylinder block, cylinder head and each radiator. When working, the fan rotates to flow the air along the air guide hood to the surface of the cylinder block and cylinder head. When the cold air flows through the heat sink, it takes away the heat given by the cylinder block and cylinder head.
2. Water cooling
The water cooling method uses water as the cooling medium to transfer the heat from the heated parts of the diesel engine. The characteristic of this cooling method is that it is easy to adjust the cooling intensity when the temperature or workload changes.
There are two types of water cooling methods: open type and closed type. In an open cooling system, the circulating water is directly connected to the atmosphere, and the steam pressure in the cooling system is always maintained at atmospheric pressure.pressure. In a closed system, water circulates in the closed system, and the vapor pressure of the cooling system is greater than the atmospheric pressure. Since the temperature difference between the cooling water temperature and the outside air temperature increases, the heat dissipation capacity of the entire cooling system is improved.
