How about Shandong Weichai generator?

The real Weichai Power Plant, Weichai Power, is still a good, old brand, but it also depends on the configured generator. The performance of the generator is also very important. Now some manufacturers' generators are configured with half copper and half aluminum, so Generators are prone to problems at that time. Generally, the performance of the entire generator set will be relatively high if it is equipped with a domestic medium-brand brushless all-copper generator. If you use it in a harsh environment, the requirements for the diesel engine and generator will be very high, especially It is the protection level of the generator, otherwise the unit will be more likely to malfunction. In addition, there are many small diesel engine factories in Weifang, all called Weichai engines. Consumers may not be able to tell them apart. Generally, the prices of other small Weichai factories are higher than The ones from the main factory are about half lower, and their general performance is not very good. They are only suitable for use once or twice a year for unit backup, and are not suitable for production.

How to install diesel generator set?

The advantages and disadvantages of water-cooled and air-cooled diesel generator sets are mainly reflected in the host.

Water-cooled diesel engines have open cycle and closed cycle. They have good cooling effect, low noise and are widely used. However, the structure is complex, the manufacturing cost is high, it is relatively bulky, it is easy to corrode, it produces scale, blockage, leakage, it loses a lot of heat, it consumes more oil, and it is more troublesome to maintain.

The air-cooled diesel engine has a simple structure, low manufacturing cost, small size, light weight, small heat loss, relatively fuel-efficient, no water leakage, freezing, scaling and other faults, short warm-up time, and environmental adaptability Good performance and easy maintenance. The disadvantages are loud noise, uneven cooling, high heat load, and high fan power consumption.

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 generate 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. The diameter of the pipe must be ≥ the diameter of the smoke outlet pipe of the silencer. The connected pipe should not have more than 3 elbows to ensure The smoke exhaust should be smooth, and the pipe should be tilted downward 5-10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upward, a rainproof cover must be installed.

4. Basic use When installing concrete, a level 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.

5. The unit shell must have reliable protective grounding. For generators that require a neutral point to be directly grounded, the neutral point must be grounded by professionals and equipped with lightning protection devices. It is strictly prohibited to use commercial power generators. The electrical grounding device conducts the neutral point to be 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. The wiring of the starting battery must be firm.

First, Weichai generatorWhen used indoors, the smoke exhaust pipe must be led to the outside. The diameter of the pipe must be the diameter of the smoke outlet pipe of the silencer. The pipe should not have more than 3 elbows to ensure smooth smoke exhaust, and the pipe should be tilted downward 5-5 10 degrees to avoid rainwater injection; if the exhaust pipe is installed vertically upward, a rainproof cover must be installed. In order to improve the output power of the diesel generator set, when the cylinder capacity and number are certain, 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. Currently, diesel generator sets use turbochargers. The compressor has strict requirements on the exhaust of the diesel generator set. Once the exhaust is not smooth or the exhaust gas speed does not meet the requirements, the air entering the cylinder decreases, which will cause the load capacity of the diesel generator set to decrease.

Second, the area around Weichai generators should be kept clean, and items that can produce acidic, alkaline and other corrosive gases and steam should be avoided nearby. Fire extinguishing devices should be equipped where possible.

Third, the installation site must be well ventilated. There should be sufficient air inlets at the Weichai generator end and good air outlets at the diesel generator end. The air outlet area should be more than 1.5 times larger than the water tank area; 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, produce carbon deposits, and affect the load capacity of the diesel generator set. ; Similarly, if the exhaust pipe does not meet the requirements and the oxygen content of the air in the engine room is reduced, it will also cause insufficient fuel in the cylinder, produce carbon deposits, and affect the load capacity of the diesel generator set.

Fourth, when the foundation is made of concrete, a level ruler must be used to measure the levelness 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.

Fifth, the unit shell must have reliable protective grounding. For generators that need to have a neutral point directly grounded, the neutral grounding must be carried out by professionals and equipped with lightning protection devices. It is strictly prohibited to use commercial The electrical grounding device conducts the neutral point to be 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 inspected and confirmed by the local power supply department.
