With the widespread application of sewage suction trucks , if people use the sewage suction truck, if there is a breakdown, we need to take precautions against failures and properly repair the sewage suction trucks so as to achieve good performance. Here are eight warnings about sewage suction trucks.
First, a brief introduction of the sewage suction truck .
1. The sewage suction truck adopts a circular tank body and has a hydraulic lifting and dumping function, which is convenient for dumping various sludges, and the rear tank door can be automatically opened hydraulically to facilitate the cleaning of sediment, solidification and cans in the tank body. Inside the body for repairs and maintenance.
2. The sewage suction truck is a new type of sanitation vehicle that collects and transfers cleanup sludge and sewage to avoid secondary pollution. The sewage suction truck can be self-priming and self-discharging. It has fast working speed, large capacity, convenient transportation, and is suitable for collecting and transporting feces. Mud, crude oil and other liquid substances.
3. The sewage suction truck adopts the domestic leading vacuum pump for suction pump, which has large suction power and long suction range. It is particularly suitable for the suction, loading and unloading of sludge in the sewer. It can suck sewer mud, silt, stones and bricks. Blocks and other large objects; especially in the reservoir of mud, crude oil, gravel, urban sewage inconvenient manual cleaning or manual cleaning difficult places, using a sewage suction truck to clean more convenient. In case of emergency, it can be used as a sprinkler, a suction truck, or a water truck (it can be cleaned internally).
Second, eight warnings of sewage suction trucks.
1, leakage
Leakage refers to the phenomenon of leakage of the fuel, lubricant (or gear oil), brake fluid (or compressed air), and power steering fluid of the sewage suction engine. This is also an obvious symptom of failure and can be found by careful observation. For example, when the compressed air leaks, the sound of air leakage can be clearly heard.
2, excessive consumption of fuel and lubrication
Excessive consumption of fuel and lubricating oil indicates that the technology of the sewage truck has deteriorated and a malfunction has occurred.
3, sewage suction car appearance is abnormal
Sewage suction truck parked on a flat site, check the appearance of the situation, such as horizontal or vertical skew and other phenomena, that is, the appearance of abnormal. The reason is that the frame, body, suspension, tires, etc., have malfunctions, which may cause troubles such as unstable direction, deviation, shift of center of gravity, and “gesture†of the wheels.
4, there is a special smell
In the operation of the sewage suction truck , if there is any failure such as brake delay or clutch slip, the burnt smell of the friction disc will be emitted; when the engine is overheated and the lubricant oil is burned, it will emit a special odor; the circuit is short circuited. When the ground wire is burned, it will also have a burnt smell.
5, exhaust smoke is not normal
In the process of engine operation, the main components of normal combustion products should be carbon dioxide and a small amount of water vapor. If the engine is not properly burned, the exhaust gas will be incompletely burned with carbon particles, hydrocarbons, carbon monoxide and a lot of water vapor. In addition, there are nitrogen oxide compounds, etc. At this time, the color of the exhaust gas may become black, blue, or white, that is, the exhaust smoke is abnormal. For gasoline engines, there should be no obvious smoke in the normal exhaust gas. However, when the lubricating oil is hung on the cylinder, the exhaust gas is blue; when the combustion is not complete, the exhaust gas is black, and when the oil is mixed with water, the exhaust gas is white.
6, high temperature
It usually appears on engines, transmissions, drive axle final drives, differentials and brakes. For example, if the engine is overheated, there is usually a problem with the cooling system. It is the lack of coolant or the pump is not working; the transmission and the transaxle are overheated, mostly due to lack of lubricating oil; the brakes are overheated and are mostly caused by the brake shoes not returning. The above phenomenon can sometimes be directly reflected by the warning light on the dashboard. It requires the driver to pay attention when he is driving, or he can test the appearance temperature by hand.
7. Abrupt changes in work status
The so-called abrupt change in the work status means that the work condition of the sewage suction truck has suddenly become abnormal. This is a relatively common fault symptom. For example, if the engine suddenly turns off and then it is difficult to start, it may not even start; the power of the engine suddenly decreases during driving, and the driving force is weak; sudden braking or running deviation during running, or even failure. The symptoms of this malfunction are obvious and it is easy to notice.
8, abnormal noise
Abnormal noise that occurs during the driving of the sewer truck is an "alarm" for the malfunction of the sewer truck. Sudden noise is given during driving. As the driver should be aware of the problem with the car, he should immediately stop and check and must not allow the vehicle to "sick up."
After a period of time, the sewer truck will have a number of large and small faults. If we know in advance the cause of the fault, we can solve it in time and avoid unnecessary troubles. We must understand the eight warning signs of the sewer truck.
