The integrated tank vacuum jetter truck is designed to optimize the structure of the sewage suction truck and optimize the use of the space at the lower part of the front head of the sewage suction tank for the installation of high-pressure plunger pumps.
The specific method is to separate the lower part of the front head to free up the installation space of the plunger pump, pipeline and base;
The sewage suction tank is divided into silos, the front silo is a clean water silo, which is used to hold cleaning water, and the rear silo is a sewage silo, which is loaded with sewage pumped by the vacuum pump.
The clean water and the sewage tank can communicate with each other to maximize the utilization rate of the tank.
Advantages of integrated tank vacuum jetter truck
Lightweight: Because the integrated tank vacuum jetter truck optimizes the transformation of the sewage suction truck, the cut part of the tank body is used to install the high-pressure pump;
The rated load mass of the whole vehicle is correspondingly reduced compared with the sewage suction truck before the modification, and the reduced part is just filled by the weight of the high-pressure cleaning system.
In addition, the integrated tank vacuum jetter truck, the clean water tank and the sewage tank can communicate with each other. After the sewage tank is cleaned, it can be used to hold the cleaning water, which greatly increases the volume of the clean water tank and is very practical when dredging long pipelines. Avoid wasting time fetching water back and forth.
Remark:
- After the use is completed, the intercommunication valve should be closed in time, so as to avoid a poor vacuuming effect during sewage suction, and sewage entering the clean water silo to pollute and block the plunger pump.
- The intercommunication function can only be used for the sewage tank to hold clean water, and the clean water tank cannot be used for the sewage suction function. Otherwise, the sewage in the clean water tank cannot be removed, and the filter and plunger pump will be blocked and other serious consequences.
Disadvantages of integrated tank vacuum jetter truck
The structure of separate bins is adopted, in order to ensure the high-pressure cleaning function of water, according to the different models (piston pump specifications).
The volume of the clean water silo generally needs to be about 2-4m3, which takes up the space of the sewage silo, resulting in a much smaller volume of the sewage tank of the same model than the separate (or side-mounted) vacuum jetter truck. For the same work, it may take a few more runs. It takes a trip to get the sewage out.
The front warehouse of the integrated tank vacuum jetter truck is used to hold clean water, and the rear warehouse pulls sewage, so when pulling sewage, the front warehouse is basically empty and the rear warehouse is full, which will cause the center of gravity of the whole vehicle to move backward, and it is easy to cause safety problems during driving. hidden danger.
In general, the integrated tank vacuum jetter truck, as a transitional model, has been gradually replaced by split and side-mounted combined dredging vehicles.
