Sewage suction trucks and fecal suction trucks are powerful tools for cleaning sewers and septic tanks. They can pump sewage quickly and are fully sealed without secondary pollution. Sewage suction trucks and fecal suction trucks are good helpers for municipal sanitation. After purchasing vehicles, many bosses engage in sanitation work and earn profits. If the sewage suction truck and the fecal suction truck are in good condition, they can naturally help the bosses to make profits, but if the vehicle breaks down, it is very annoying. Proper maintenance is necessary to keep your vehicle running smoothly. Sewage suction truck manufacturers explain to you how to maintain the vehicle.
The maintenance of the chassis of the sewage suction truck and the fecal suction truck will not be described here. This time I will mainly talk about the maintenance of the special part.

1. Maintenance of the tank body of the sewage suction truck
1. The paint on the outside of the tank of the sewage suction truck is peeled off and cracked, which will cause the tank to rust. Therefore, the paint on the tank should be repaired in time, otherwise the tank will be rusted and corroded.
2. After the sewage suction truck operation is completed, clean the inner wall of the tank in time to prevent the sewage sludge from corroding the inner wall of the tank. If conditions permit, do a resin anti-corrosion coating on the inner wall of the tank once a year, which can effectively prevent the tank from corroding.
3. The valves on the tank body need special attention when the weather is cold to prevent the water stains inside the valve from freezing and cracking the valve. The treatment method is to open the valve to the half-open state after the vacuum sewage suction truck operation is completed, so that the water stains in the valve can flow out.

2. Maintenance of vacuum pump of fecal suction truck
1. The XD rotary vane vacuum pump needs to maintain sufficient oil volume. If the oil volume is found to be insufficient, it needs to be added in time. Every 100 hours of sewage suction, the oil of the oil-air separator and vacuum pump needs to be replaced. The continuous operation time of the sewage suction truck using the XD rotary vane vacuum pump cannot exceed 20 minutes. It is found that there is smoke from the vacuum pump, indicating that the pump body is already high temperature, and the power take-off should be turned off to allow the vacuum pump to dissipate heat and rest.
2. When the water ring vacuum pump is in operation, the water in the water tank also needs to maintain a sufficient water level. If the water is found to be insufficient, add it in time. Every 100 hours of sewage suction, the water in the water tank and water ring vacuum pump needs to be replaced.
3. The part where the special part of the vacuum sewage suction truck is buttered: 1. The connection between the two oil cylinders of the tank body of the sewage suction truck. 2 The connection of the two oil cylinders where the back cover of the vacuum sewage suction truck is opened. 3. The connection between the tank body and the back cover 4. The universal joint on the power transmission shaft. 5. The mechanical seal of the water ring pump. 6. The connection between the tank body of the sewage suction truck and the sub-beam
4. Cleaning of the anti-overflow valve, water vapor separator and dung window of the fecal suction truck
The float ball and sealing rubber ring in the overflow prevention valve of the fecal suction truck need to be cleaned frequently and kept clean, so that it can play a better role in preventing overflow. The oil pollution in the water vapor separator is often checked and discharged, which can also play a good role in preventing overflow. The clean dung window can better observe the water level in the tube tank and avoid the overflow of the tank.
