When installing Weichai diesel generator sets, there are six points to note:
First, Weichai generators are used indoors, and the exhaust pipe must be led to the outdoor. The pipe diameter must be ≥ the diameter of the smoke pipe of the muffler. The elbow of the connected pipe should not exceed 3 to ensure smooth exhaust. 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. In order to increase the output power of diesel generator sets, in the case of a certain cylinder capacity and number, only by forcing more air into the cylinder to fully burn the fuel in the cylinder, can the average effective pressure of the unit be increased. At present, diesel generator sets use turbine boosters. Compressor, which has stricter requirements on the exhaust of diesel generators. Once the exhaust is not smooth or the exhaust gas speed cannot meet the requirements, the air entering the cylinder is reduced, which will cause the load capacity of the diesel generator to decrease.
Second, the surrounding of Weichai generator should be kept clean to avoid placing nearby items that can generate acidic and alkaline corrosive gases and steam. Conditional should be equipped with fire extinguishing devices.
Third, the installation site should be well ventilated. Weichai generator end should have sufficient air inlet, diesel generator set end should have good air outlet. The area of the air outlet should be more than 1.5 times the area of the water tank; the air inlet is not smooth or does not meet the requirements, and less air enters the cylinder, which will cause insufficient fuel in the cylinder, cause carbon deposits, and affect the load capacity of the diesel generator set ; Similarly, the exhaust pipe does not meet the requirements, and the oxygen content of the air in the engine room will be reduced, which will also cause insufficient fuel in the cylinder, generate carbon deposits, and affect the load capacity of the diesel generator set.
Fourth, when concrete is used for the foundation, the level must be measured with a spirit level during installation to fix the unit on a level foundation. There should be special anti-shock pads or foot bolts between the unit and the foundation.
Fifth, the unit casing must have reliable protective grounding. For generators that need a neutral point to be directly grounded, professionals must perform neutral grounding and configure lightning protection devices. It is strictly forbidden to use the grounding device of the city power supply for neutrality. The point is directly grounded.
Sixth, the two-way switch between the generator and the mains must be very reliable to prevent power transmission. The wiring reliability of the two-way switch needs to be verified by the local power supply department.
