The popularity of sewage suction trucks has greatly improved the efficiency of sanitation workers. Let sanitation workers more easily and quickly clean up the sludge in sewage tanks and sewers. However, everyone will encounter various problems in the process of using the suction truck. For example, the corrosion of the tank body of the sewage suction truck results in the reduction of the service life of the sewage suction truck. Today we will talk about how to prolong the service life of sewage suction vehicles by slowing down the corrosion of the tank body of sewage suction vehicles.

Everyone knows that the tanks of sewage suction trucks are generally made of carbon steel. The thickness of the tanks of small and medium-sized sewage suction trucks is generally five centimeters or six centimeters. The tank body of sewage suction truck mainly depends on its own material, which is the corrosion resistance of carbon steel itself to resist corrosion. The tank body of the sewage suction truck is under the corrosiveness of sludge, under the rust of oxygen, water and temperature, and under the pressure stress of sewage suction and sewage discharge, the tank body is usually already in use for 4-5 years Corrosion penetrates. Is there any good way to reduce the corrosion of the tank body of the suction truck? The answer is yes.

1. First of all, when making the tank body of sewage suction truck, we use high-quality carbon steel plate, high-quality carbon steel plate, which has better corrosion resistance and naturally has a longer service life.

2. Spray anti-corrosion layer inside the tank body of sewage suction truck. The anti-corrosion layer can effectively avoid rust, and the life of the tank body of the sewage suction truck with the anti-corrosion layer is two years longer than that of the tank body without the protective layer. It is also said that spraying a layer of anti-corrosion paint inside the tank body of the truck can also achieve the anti-corrosion effect. But the anti-rust paint in the world is generally acid paint, and the sludge sucked by the sewage suction truck is alkaline. The chemical reaction between the acid and the base causes the acid anti-rust paint to quickly fail. Therefore, spraying the anti-corrosion layer is an effective method.

3. After the suction truck operation is completed, it needs to be cleaned up in time. The residual debris in the tank body should be emptied and removed in time to prevent the remaining impurities from corroding the tank body of the suction truck. Keeping the inside and outside of the tank clean and dry is a good way to effectively reduce corrosion.

4. Avoid prolonged exposure to the sun to avoid damage to the paint of the tank and cause it to fall off. If the paint on the tank is scratched, repair it in time to avoid corrosion of the tank.

5. Regularly inspect and maintain the tank body. If it is found that the tank body has rusted and penetrated, it is necessary to repair the eroded area in time. After repairing, it will not affect the use effect of the suction truck.

Sewage suction tank is the main body of sewage suction truck, it is the container that holds sewage debris, and it is the main medium for generating vacuum suction. Therefore, the maintenance of the sewage suction tank occupies a high proportion in the maintenance of the vacuum sewage suction truck, which needs the attention of the vehicle owners.

The vacuum pump of the sewage suction truck is the main device for generating suction. A good sewage suction pump will make your sewage suction truck more efficient and energy-saving. There are two main types of vacuum pumps used in sewage suction trucks, namely rotary vane vacuum pumps (commonly known as oil pumps) and water circulation pumps. The water circulation pump is quickly recognized by everyone because of its simple structure, easy maintenance, low cost of use, and high speed of sewage suction. More and more people choose to install water circulation pumps in vacuum suction trucks.

Although the structure of the water circulation pump is simple, it also needs to be maintained. Otherwise, it will be awkward with your temper, making your suction truck's suction power smaller and even unable to suck the pollution. Now let's talk briefly about how to maintain and maintain the water circulation pump of the vacuum suction truck.

1. Regularly check the lubrication of bearings. Grease the bearings 3-4 times a year, and clean the bearings at least once a year. In this way, the wear of bearings can be reduced, the service life of the water circulation pump can be extended, and the operating cost of the vacuum suction truck can be reduced.

2. Pay attention to the temperature of the bearings operation. When the water circulation pump is working, the temperature of the bearings is 15 degrees to 20 degrees higher than the outside temperature, and the maximum is not allowed to exceed 55 degrees to 60 degrees. If the bearings temperature is found to be abnormal, the suction truck needs to stop the operation immediately and check the cause.

3. If the sewage suction truck uses a packing-sealed water circulation pump, the packing needs to be compressed regularly. If the required sealing performance cannot be guaranteed due to the packing wear, the new packing should be replaced. When cleaning the bearings every year, the remaining packing should be cleaned up and replaced with new packing. The packing cannot be compressed too tightly, allowing water to drip out to ensure cooling and sealing.

4. If the vacuum suction truck uses a mechanically sealed water circulation pump, leakage occurs, you should check whether the dynamic and static circulations of the mechanical seal have been damaged, or the seal circulation is aging. If the above situation occurs, you need to replace the new accessories.

5. Regularly check the transmission belt on the water circulation pump. When the belt has cracks, scratches, damage, cracks in the overlapping parts, etc., the belt should be replaced in time to prevent the belt from suddenly breaking and hurting the person when the suction truck is operating. Adjust the tightness of the belt with the tensioner.

6. Pay attention to the water level of the water circulation pump water tank at any time. More rather than less. Do not let the water circulation pump lack water to prevent the phenomenon of burning the pump.

7. Regularly clean the rust residue in the water tank to prevent the rust residue flow into the water circulation pump and damaging it.

8. Prevent backflushing. Prevent the sewage from being sucked into the water ring pump during the operation of the sewage suction truck. Once this happen, immediately stop the operation, and disassemble the water circulation pump, clean the pump cavity, water tank, four-way valve, etc. Prevent damage to the water circulation pump.
