The sewage tank and clean water tank of the pipeline dredging vehicle need to be cleaned regularly. When cleaning, the back cover needs to be opened and the tank body should be lifted. How does the cleaning and suction truck operate when the rear cover is opened and the tank is lifted? What should I pay attention to during operation? Here for everyone to explain, to prevent misuse.
How to open the back cover of the dredging truck?
The back cover of the multi-functional sewage suction truck is usually closed, and it is closed and tightened by the two hydraulic cylinders on the left and right sides of the rear of the tank. In addition, there will be 2-4 locking bolts to lock it. To open the rear cover of the cleaning and suction truck, first stop the car steadily and pull the handbrake before proceeding. After making sure that the vehicle is parked safely and smoothly, the engine can keep running, but the gear must be in neutral. We came to the rear of the cleaning and suction truck. At this time, we can see 2 or 4 locking bolts on the rear cover of the rear tank. First, use the power lever to loosen all the locking bolts on the rear cover and withdraw them to ensure that the locking bolts will not hook the flange when the rear cover is opened. Then come to the cab, step on the clutch and hang the power take-off, and the hydraulic pump starts to run. Finally, we came to the hydraulic operation place and moved the hydraulic handle that controls the opening and closing of the tail cover to open the rear cover of the cleaning and suction truck.
Precautions when opening the back cover of the multi-functional sewage suction truck: When opening the back cover of the pipeline to dredge the truck, be sure to first ensure that the locking bolts on the back cover are loosened and withdrawn, and will not hook the locking hook or flange. , and then move the hydraulic handle. If the hydraulic handle is pulled before the locking bolt is completely loosened, the hydraulic cylinder will be pushed out to open the tail cover, while the locking bolt will pull the tail cover and prevent it from opening. Two huge opposite forces are concentrated on the tail cover. , it will cause deformation of the tail cover or the connection between the tail cover and the tank body will fall off.
2 How does the pipeline dredging truck lift the tank?
The tank of the multi-functional sewage suction truck is usually placed horizontally on the chassis beam. When the tank needs to be lifted, there are two hydraulic cylinders at the bottom of the tank to lift the tank. To lift and clean the tank of the sewage suction truck, first stop the truck steadily and pull the handbrake before proceeding with the subsequent operations. After making sure that the vehicle is parked safely and smoothly, the engine can keep running, but the gear must be in neutral. Then step on the clutch and hang the power take-off, and the hydraulic pump starts to run. Finally, we came to the hydraulic operation place and pulled the hydraulic handle that controls the lifting of the tank to lift the tank of the pipeline dredging truck.
Precautions when lifting the tank body of the pipeline dredging truck: Before the pipeline dredging truck is ready to lift the tank body, the truck needs to be parked in a stable and safe place, not a ramp or a soft ground. Because the pipeline dredging truck is in the process of lifting the tank body, due to the lifting of the tank body, the center of gravity of the whole vehicle moves backward. If it stops on a slope or soft ground, it is easy to roll over or the rear wheel sinks and other dangers. Secondly, before the tank is lifted, it must be ensured that the sewage tank has been emptied or the back cover has been opened. Resolutely do not lift the tank when the sewage tank is full. Lifting the tank when the sewage tank is fully loaded will cause the hydraulic system to be overloaded, and it is easy to cause failures in a series of hydraulic components such as hydraulic cylinders, multi-way valves, hydraulic pumps, and hydraulic pipes.
Although the two operations of opening the back cover and lifting the tank body of the pipeline dredging vehicle are relatively infrequent, there must be misoperations, which will lead to serious consequences and huge economic losses. Therefore, in the operation process, it is best to first go through the entire operation process in your mind, and then operate. When operating, be calm and don't be impatient
