Signs Before A Sewage Suction Truck Breaks Down

2022-05-18

1. Leakage on vacuum tank truck

Leakage refers to the leakage of fuel, lubricating oil (or gear oil), brake fluid (or compressed air) and power steering fluid of automobile engine. This is also an obvious symptom of a malfunction, which can be found by careful observation. For example, when compressed air leaks, the sound of air leakage can be clearly heard.

2. Excessive consumption of fuel and lubrication on sewage suction truck

Excessive consumption of fuel and lubricating oil indicates that the technical condition of the car has deteriorated and has developed a malfunction.

3, Has a special smell

During the operation of the car, if there are faults such as braking lag, clutch slippage, etc., the burnt smell of the friction pads will be emitted; when the engine is overheated and the lubricating oil is burned in the cylinder, a special smell will be emitted; the circuit is short-circuited and grounded. There is also a burnt smell when the wire is burnt.

4. The appearance of the vacuum tank truck is abnormal

The car is parked on a flat site, and the appearance is checked. If there is horizontal or vertical skew, it is abnormal in appearance. Most of the reasons are the failure of the frame, body, suspension, tires, etc., which will cause unstable direction, deviation, and center of gravity transfer when driving.

5. Changes in working conditions of sewage truck

The so-called sudden change of working condition refers to the sudden abnormal phenomenon of the working condition of the car, which is a relatively common fault symptom. For example, it is difficult or even impossible to start the engine after the engine is suddenly turned off; the power of the engine is suddenly reduced during driving, and the driving is weak; the braking suddenly fails or deviates or even fails during driving. The symptoms of this kind of failure are obvious, so it is easy to detect.

6. Abnormal noise from vacuum truck

The abnormal sound of the car in the driving process is the "alarm" of the car failure. If there is an abnormal noise suddenly during driving, as a driver, you should realize that there is a problem with the car, and you should stop and check immediately, and must not allow the vehicle to "work with illness".

7. The color of exhaust smoke is abnormal

During the working process of the engine, the main components of normal combustion products should be carbon dioxide and a small amount of water vapor. If the engine does not burn properly, the exhaust gas will be mixed with incompletely burned carbon particles, hydrocarbons, carbon monoxide and a large amount of water vapor. In addition, there are nitrogen oxides, etc. At this time, the color of the exhaust gas may turn black, blue or white, which means that the color of the exhaust smoke is abnormal. For gasoline engines, there should be no obvious smoke in the normal exhaust. However, when the lubricating oil runs up the cylinder, the exhaust gas is blue; when the combustion is incomplete, the exhaust gas is black, and when the oil is mixed with water, the exhaust gas is white.

8. Overheating and high temperature of sewage truck

Usually appear on the engine, transmission, drive axle final reducer, differential and brakes and other assemblies. For example, if the engine is overheated, it is mostly caused by a problem with the cooling system, which is caused by a lack of coolant or the pump does not work; the transmission and the drive axle are overheated, mostly caused by a lack of lubricating oil; and the brakes are overheated, mostly caused by the brake shoes not returning. The above phenomena can sometimes be directly reflected by the warning lights on the dashboard. Drivers need to pay attention when driving, or they can test the external temperature by hand.
