What is the reason for the low suction power of the cheapest sewage suction truck?
Cheapest sewage suction truck is a new type of sanitation vehicle that collects and transfers sludge and sewage to avoid secondary pollution. It is mainly used to clean urban sewers, sediments in pipelines, dredging of dead-end mud ditch, and can also be used to clean industrial drainage pipelines. , walls, etc. Cheapest sewage suction trucks mainly rely on suction to carry out sewage suction operations. What is the reason for the low suction power of cheapest sewage suction trucks?
Reason 1: Air leakage. The cheapest sewage suction truck uses a vacuum pump to discharge the air in the tank to form a vacuum, form a negative pressure, and use the pressure of the air to generate suction. Then, if there is air leakage in the sewage suction tank, sewage suction pipeline, and vacuum exhaust pipe of the cheapest sewage suction truck, and the vacuum state cannot be achieved, then sufficient suction cannot be generated, and the phenomenon of insufficient suction will occur.
Reason 2: The vacuum pump of the cheapest sewage suction truck is worn. The wear of the vacuum pump generally has two aspects, one is the wear of the pump casing, and the other is the wear of the scraper. The vacuum pump will slowly wear out after a long time of use. If the casing is worn Seriously, the inner wall of the shell is not smooth, and there are grooves. At this time, the maintenance will not work, and it can only be replaced. The wear of the scraper is relatively common. After the tube piece is worn, it cannot be attached to the inner wall of the sewage pump to form a vacuum. At this time, the scraper needs to be replaced in time.
Reason 3: The valve of the sewage suction pipe is closed or insufficiently opened, or the suction pipe is blocked. At this time, even if the vacuum pump generates enough suction, because the suction is blocked in the valve or pipeline, the sewage cannot smoothly enter the suction pipe. In the sewage tank, it will cause the illusion that the suction of the cheapest sewage suction truck is small.
