The cleaning and suction truck is a very popular sanitation vehicle at present. It integrates two functions of high-pressure cleaning and sewage suction. It can be used as a high-pressure cleaning vehicle or a sewage suction vehicle. Can realize the function of two kinds of cars. Practical, cost-effective, and powerful are the characteristics of cleaning and suction trucks.
At present, there are many models of cleaning and sewage suction vehicles, but in terms of functions, they are divided into two types, one is a cleaning sewage suction vehicle with an auxiliary engine, and the other is a cleaning sewage suction vehicle without an auxiliary engine. Literally everyone can see the difference between them. One is that an auxiliary engine is added, while the ordinary one does not have an auxiliary engine.
The power of the high-pressure cleaning pump and vacuum pump of the ordinary cleaning and suction truck comes from the engine of the vehicle itself. The engine generates power, and the power is exported through the differential box (or power take-off), and then the differential box is connected with the high-pressure cleaning pump and the vacuum pump by the full-motion shaft with universal joints. In this way, the high-pressure cleaning pump and vacuum pump of the cleaning sewage suction truck are powered, so as to realize the functions of high-pressure cleaning and sewage suction. In order to prevent insufficient power and prevent excessive wear of the gearbox and sub-speed case, the cleaning function and the sewage suction function of the cleaning and suction truck cannot be used at the same time.
But sometimes, in order to pursue work efficiency, when we need to use high-pressure cleaning and sewage suction functions at the same time, ordinary combined dredging vehicles cannot meet our needs. So the combined dredging vehicle with the auxiliary engine appeared. Combined dredging vehicles with auxiliary engines generally use a high-pressure cleaning pump to connect to the vehicle's own engine, and a vacuum pump to connect to the auxiliary engine. In this way, two engines drive two pumps, which can clean and suck dirt at the same time, and because of sufficient power, the effect of cleaning and sucking dirt is better.
But the cleaning and suction truck with the auxiliary engine is so good, why do people rarely see the cleaning and suction truck with the auxiliary engine on the street? There are several reasons:
1. The cleaning and suction truck with auxiliary engine has an additional engine, which increases the cost and makes the price more expensive.
2. The cleaning and suction truck with auxiliary engine has an additional engine, which increases the weight, and is prone to overweight, and the risk of entry is high.
3. The use and maintenance costs of the cleaning and suction truck with auxiliary engine have increased a lot because of the addition of an additional engine.
4. The cleaning and suction truck with auxiliary engine takes up space due to the addition of an additional engine, resulting in a smaller volume of the clean water tank and the sewage tank.
The addition of an engine has brought a lot of problems, which is why people rarely see a cleaning and sewage suction truck with a secondary engine.
