Many customers have encountered problems in cleaning up the biogas tank and asked whether to purchase a biogas digester or a suction truck. Before clarifying this issue, we first understand the difference between these two models. From the point of view of the name, it is possible to absorb dirt and inhale the excrement. There is no definite boundary, and they still have many different places.
1, the two tanks are not the same shape
The tank body of the manure suction vehicle is an elliptic turtle-back design, and the digester suction tank is a cylindrical structure. In terms of functional principle, both models use the negative pressure generated by the air to carry out the sewage suction operation, and if the tank body is designed into a cylindrical structure, the pressure of the tank body will be higher, so the sewage suction vehicle is more capable than the suction truck. Stronger, the price is relatively expensive.
2, the two different vacuum pump configuration
The vacuum pump of the biogas digester suction truck is generally equipped with a higher power, and it is the first domestic vacuum pump of the Veyron series. Sewage suction truck can not only easily absorb sludge, gravel, small bricks and other impurities from the sewer into the tank, but also can absorb impurities such as crude oil in industrial pipelines that are difficult to absorb. The manure suction pump of the suction truck is relatively weak, and it is generally used to absorb the sewage inside the sewer and the liquid material such as the manure in the septic tank. The suction is much weaker than the suction truck.
3, the two different ways of sewage
Suction trucks are relatively easy to discharge due to the substances they absorb. Therefore, only one retention valve is installed at the tail of the tank. The pressure of the vacuum pump is used to squeeze and discharge the dirt. It is convenient for self-priming and self-discharging. The sewage suction vehicle is relatively complex because of the material it is sucking. Therefore, a self-retaining valve is not only installed in the tail of the tank, but also a hydraulic dump system is added to the rear of the tank. The rear tank door can be automatically opened hydraulically, double top Self-unloading to facilitate the discharge of waste from the tank.
4. The operating environment of suction trucks and sewage suction trucks is different.
This is one of the issues that customers are most concerned about. Because the suction truck is lower in configuration than the suction truck, the operating environment is relatively easy, such as schools, communities, sewers in urban and rural areas, rainwater wells, and septic tanks in farms. The sewage suction truck can not only fully satisfy all the working environment of the suction truck, but also can adapt to the harsher working environment, such as sludge in the ditch, petrochemical plant sewage sludge, crude oil and other substances can easily draw. Therefore, the performance of the sewage suction truck is better than the suction truck, and the price is relatively expensive.
Summarizing the above, the sewage suction truck has a wider range of use, adapting to the environment is more complex, the power of the sewage suction is greater, and the price is higher. The suction truck has a simpler application environment, simple functional structure and relatively cheaper prices. Through the above comparison of the differences between the two, customers can choose the appropriate cleaning vehicle according to their needs.
