In the previous article, I introduced the configuration of the sewage suction truck operating in the plateau area. Now I will talk about how to choose the configuration of the sewage suction truck operating in the plateau area. Cleaning the sewage suction truck is the same as the sewage suction truck. In the plateau area, it also needs special configuration according to the special environment of the plateau.
Compared with single-function sewage suction trucks, the cleaning and suction trucks in plateau areas have higher requirements in terms of power. The engine of cleaning the sewage suction truck is the same as the engine of the sewage suction truck, because the air in the plateau area is thin and the oxygen content is insufficient, the power will be reduced.
Moreover, the cleaning and suction truck integrates the cleaning function and the dirt suction function, resulting in a more compact structure and greater weight. Take the smallest volume of Dongfeng Xiaodolika cleaning sewage suction truck as an example. Its dead weight can reach 5-5.5 tons, which is about 1 ton heavier than the same model of sewage suction truck. Not only is self-heavy, the volume of the Xiaodolika cleaning sewage suction truck is also larger than the volume of the sewage suction truck. The volume of Xiaodolika cleaning sewage suction truck consists of two parts: the water tank volume is 2 cubic meters meters, the sewage tank volume is 4 cubic meters meters, and the total volume is 6 cubic meters meters. The volume of the sewage suction truck is 4 cubic meters meters. The weight is heavy, coupled with the load, so compared with the sewage suction truck, the cleaning and suction truck has a greater demand for power, and the power is insufficient. During the driving process, it will be difficult to start and the engine load will be large.
Therefore, when choosing an engine for a cleaning and suction vehicle, you need to choose an engine with an excellent brand of horsepower.
In terms of pollution suction, the principle and function of cleaning sewage suction trucks are the same as those of sewage suction trucks. Therefore, the problems that will occur when sewage suction trucks are used in plateau suction operations will also occur when cleaning sewage suction trucks. When choosing a sewage suction pump, it is necessary to refer to the sewage suction truck operating in plateau areas. I won’t introduce more here. You can refer to the previous article: What configuration should be selected for sewage suction trucks operating in plateau areas? .
In terms of high-pressure cleaning, when selecting high-pressure pumps for high-pressure cleaning sewage suction trucks operating in plateau areas, it is also necessary to choose high-pressure pumps with low power requirements. The power of the high-pressure pump comes from the engine of the chassis. The engine transmits power to the gearbox, the gearbox transmits the power to the power take-off, and finally the power take-off transmits the power to the high-pressure pump. If the power is transmitted many times, there is bound to be loss. Coupled with the lack of oxygen in high-pressure areas, the engine's power oxygen is insufficient, and the power drops. Therefore, when selecting a high-pressure pump for the cleaning and suction truck operating in the plateau area, it must be calculated based on the actual power of the chassis engine in the plateau area.
In addition, the plateau area is not only lack of oxygen, but also low temperature and long freezing time. Therefore, cleaning and suction trucks operating in high-pressure areas not only need to install a drain valve on the pump body, but also need to install an air-pushing device. In the cold season, when the high-pressure cleaning operation is completed, the air-pushing device is used to discharge the water in the high-pressure pump body and the high-pressure cleaning pipe to prevent freezing and damage the high-pressure pump and the high-pressure pipe.
Summary: Clean and suction sewage trucks operating in plateau areas require high-horsepower engines as low-horsepower engines to configure vacuum pumps and high-pressure cleaning pumps.
