Precautions

1. Water requirements

When Sewer Jetting Truck uses rivers and ponds as water sources, pay attention to the end of the suction pipe all submerged in the water. To avoid inhaling stones or more sediment and floating debris, the end of the suction pipe is generally equipped with a filter device, and it is strictly forbidden to remove the filter device when absorbing water. If the water source is shallow, it is necessary to dig the water absorption place deeper in advance to ensure that it does not contain debris and does not enter the air.

2. Add water

Before each time the centrifugal pump absorbs water, a certain amount of water must be added to the pump, and the water inlet must be closed after adding. When the self-priming pump is used for the first time, it is necessary to add water diversion, and it is not necessary to add water diversion later.

3. Water inlet pipe

When absorbing water, the water inlet pipe system must maintain a certain degree of vacuum before the water can be sucked into the tank. The water inlet pipe system must be sealed and reliable, the hose must not be damaged, and the hard pipe must not have cracks, otherwise, the Sewer Jetting Truck will leak air, which will result in the inability to absorb water.

4. Parking and gearing

Whether the Sewer cleaning truck is absorbing water or working, the power take-off device must be in gear when it is parked.

5. Release water in winter

Before winter comes, the water in the water pump and water pipe should be emptied to prevent freezing and cracking. Generally, there is no construction in the severe winter in northern my country. Therefore, after the construction is completed, the water in the Sewer Jetting Truck's water pump and water pipe should be emptied immediately to prevent future troubles.

6. Regular sewage discharge

The Sewer cleaning truck water storage tank is provided with a sewage pipe, and the inlet of the pipe is the lowest point of the water tank. After a period of use, the drain pipe switch should be turned on regularly to remove the accumulated debris in the tank until the water becomes clear.

Maintenance steps

1. To remove the stubborn traces left on the car body, you can carefully scrub with all-purpose descaling water and clean cotton cloth, then wring out the clean cotton cloth dipped in car washing liquid and dry the paint surface of the car body in the direction perpendicular to the driving of the car.

Finally, rinse the car wash with plenty of water, and dry it with a synthetic sheepskin towel in time. Wipe dry to achieve no watermarks on the whole car and no stains on the glass

2. High-pressure water gun cleaning is to use a high-pressure water gun to wash away the sediment contaminated on the surface of the Sewer cleaning truck body from top to bottom, then wash the rear of the body, and finally wash the lower part of the car. Note that in this step, the chassis should be thoroughly rinsed, and the edges, bends, fenders, etc. should be thoroughly cleaned. In particular, the wheels, brake discs, fenders, front grilles, door inner frames, and skirts should be thoroughly washed with sand and dirt.

3. Wipe, use a car wash sponge dipped in a shampoo car wash, wipe the car body once, if the contamination is not easy to remove, you can wipe it repeatedly, pay attention to wipe the upper and lower sponges of the car body to be used separately, to avoid the sand on the lower part of the Sewer cleaning truck from scratching the car body paint noodle. Then rinse with high-pressure water, especially the residues such as foam at the seams and corners of the car.

4. Apply the liquid and sprinkle the shampoo car wash liquid on the Sewer cleaning truck. There are two methods. One is to use a multi-functional high-pressure foam cleaning machine, which should be evenly sprayed and the nozzle should be shaken up and down regularly; dewaxing detergent.
