First check whether the excitation circuit is broken and whether the fuse is burned out.
If the machine does not generate electricity, it may be a problem with the generator or the generator relay. The engine is burning oil, or the oil pressure is insufficient, etc. For reference only, as for the engine oil light that stays on, it may be due to lack of engine oil. After replacing the wastegate valve, the Great Wall Fengjun 6 diesel pickup truck sped away, causing the engine to not start properly, vibrating and making abnormal noises, and the idle motor of the car was above the throttle transmitter. It is mainly used to bear the idling speed of the car. Its purpose is to adjust the idling speed according to the engine load at idling speed. If the idling speed jitters, you can check the pointer fluctuation of the idle speed meter, which generally indicates poor combustion.
How to install the Great Wall Fengjun five accessory booster pump belt
The method is as follows:
1. Wrap it with polyester insulation tape When done, make sure to press down half of the 1st circle, wrap 8-12 layers, then wrap them again. The two layers are then wrapped with tape for strength.
2. Take out the copper core of the vacuum pump cable from a place about 30-35 mm long, wipe the copper wire clean with emery cloth, and take out the copper wire of the three-core cable from a place about 30-35 mm long. , wipe clean with emery cloth, and plug the three-core cable and the copper part of the external cable together. Then, glue it tightly with thin copper, cut off the remaining part, and flatten it with scissors to prevent knots.
3. Weld the three wire ends of the vacuum pump firmly with solder. The surface of the welding head is required to be smooth, without burrs or false welding. If it is not soldered firmly or is not smooth, the vacuum pump should be re-soldered until the requirements are met. .
4. Wrap the three wires together with plastic tape. Layer 1 is larger than 50 mm at the end of the insulation layer. The second layer extends 50 mm beyond the end of the first layer.
5. After packaging, use a pot of cold water to safely soak the packaging line in the water. After 12 hours, the insulation layer shall not be less than 50MW500 gauge pressure. Otherwise, it should be repackaged if necessary.
6. The grounding wire of the vacuum pump should also be packaged in accordance with the technical requirements of submarine cable lines.
7. When connecting the vacuum pump, constantly observe the changes in insulation resistance to prevent damage to the cable insulation.
8. After the vacuum pump is connected, while going down the well, continuously measure the insulation resistance to observe its changes to prevent the cable insulation from being hung on the well wall. If the insulation level is found to drop rapidly below 0.5 megohm, Lift the unit up to detect the cause.
The installation method of the Great Wall Fengjun five-accessory booster pump belt is as follows:
1. Pull out the generator main shaft to facilitate subsequent winding of the belt.
2. Adjust the position of the generator main shaft.
3. The two idler wheels of the generator are pulled outward.
4. Wrap the belt around the idler pulley of the generator.
