Inventory of faults on 16-point suction trucks
The environment in which sewage suction trucks work has always been rather harsh, and therefore, it is more important for their maintenance. Sometimes it is unavoidable to have some minor faults. How do you judge the faults of the 16-side suction trucks ? What are the common signs?
1. Abnormal noise, if abnormal sound occurs during driving, it is usually a malfunction “alarmâ€. If the driver finds that he should promptly get off the vehicle, he must not allow the sewage suction truck to “sickly work†to avoid losses. Bigger.
2. The exhaust smoke color is not normal. In the work process of the sewage suction truck, the main components of normal combustion products should be carbon dioxide and a small amount of water vapor. If it is found that the color of the exhaust gas discharged from the sewer truck turns black, blue, or white, it proves that the engine of the sewer truck does not burn properly. In the case of a gasoline engine, the exhaust fumes should normally be free of visible smoke. If the tail gas is blue, it is generally because the lubricating oil is snagged onto the cylinder; if the tail gas is black, it means that the fuel combustion is not complete; if the exhaust gas is white, it means that the oil is mixed with water.
3, the temperature is too high, the suction temperature is high, the general department will appear is the engine, transmission, drive axle main reducer, differential and brake assembly. Suction truck engine overheating is generally due to problems with the cooling system, lack of coolant or pump does not work; if the transmission and transaxle overheated, mostly due to lack of oil due; if the brake overheated, mostly because the brake shoe Do not return to cause. In addition, these phenomena can be directly reflected by the dashboard warning lights. Therefore, when driving a sewage suction truck, the driver should always pay attention to observation, or can directly test the appearance temperature by hand.
4, leakage, generally refers to the sewage suction car engine fuel, lubricants, brake fluid and power steering fluid leakage. These phenomena are relatively intuitive, and we only need to pay more attention to it.
5, there is a special odor, Cheng Li suction truck in operation, if there is brake delay, clutch slip and other faults, will emit the burning smell of the friction plate; suction engine car engine overheating, lubricating oil cylinder burning, Will emit a special odor; a short circuit, when the ground wire is burned, it will also have a burning smell.
The above is a sign of the failure of the 16-party suction truck . Therefore, during driving, the driver should immediately stop and inspect these phenomena. If the situation is serious, he should promptly send it to the repair shop to avoid further serious consequences.
