Sewage suction truck is a kind of sanitation cleaning vehicle. Its main purpose is to clean the pipelines of cities, the sediments of sewers and the dredge of dead mud. Of course, sewage suction trucks can also be used to clean industrial walls and pipelines, etc. It can be used for the purpose of transporting water and spraying water, and can also be applied to emergency fire fighting at critical times. Sewage suction trucks are sealed vacuum systems that can be used to automatically inhale canisters into the tank with some effluent and manure or other fluids above and below the surface. Then the operation is the same in reverse. You can use the liquid pipe to discharge the liquid to some designated locations or containers. It is also very convenient for the operation of various liquids. In the structure design of the sewage suction truck, Its container is designed as an ellipsoid, which is able to obtain a stable pressure resistance in the tank, and it can also prolong the service life of the tank. The four-way reversing valve of the vehicle can easily change the direction of the gas flow direction of the airway, so that the sewage suction truck can not only achieve the function of automatic liquid discharge, but also can achieve the function of automatic liquid washing. The boom of the vehicle can be turned around approximately 270 degrees, which can make it suitable for a variety of different geographical environments. The vacuum system of the sewage suction truck is also an important part of the engine. The vacuum pump is also a power machine for fluid and energy. After the vacuum pump sucks out the air from the tank, the tank will generate a certain vacuum so that the liquid can be pumped into the tank under the pressure of a tank and atmospheric pressure. When the vacuum pump is working, the flow sequence of the air flow in the air path is: the air in the suction truck with a certain humidity, and the first is the water-gas separator, and after the water is separated, it flows to In the tank, gas will follow the gas pipeline through the four-way valve and finally to the inlet of the vacuum pump. The gas is mixed in the pump with the pump's lubricating oil. After the pump is discharged from the exhaust port in the compression chamber this time, then The oil and gas mixing zone can be initially separated by passing through the primary filter, the separated oil flow will flow into the oil tank, the mixer will be separated again by the fine filter, enter the four-way valve, and finally discharged into the atmosphere. Then, when the liquid needs to be discharged from the tank to the outside, the four-way valve will be in a row, which will change one direction of the air flow in the air path. The direction of the air flow is exactly the opposite when the liquid is pumped. The vacuum pump pushes the outside air into the tank, allowing it to generate a pressure of atmospheric pressure, and it can press the liquid from the tank through the suction pipe. Out, and then for the other part of the working principle is the same with the suction pump when pumping liquid. (Text / Sun Ni)

POINTS TO ATTENTION:
1- Keep a careful check on gear ring before installation, replace one if damages.
2-Installed surface of both motor and generator should be kept clean, Make sure the strength to the bolts.
3- Clean each connection port, Strictly observed the sketch, Make sure of firm connection and tight electric conduction.
4- Check if the key could be automatic
