Tips for efficient use of sprinkler trucks
2025.09.21
Before using a sprinkler truck (Dongfeng or Jiefang), carefully read the user manual. Strictly following the usage requirements is an important guarantee for using the sprinkler truck well.
1. Requirements for water sources
When the sprinkler truck (Dongfeng or Jiefang) uses rivers, ditches, and ponds as water sources, be sure to submerge all the ends of the suction pipe into the water. To avoid inhaling stones or large amounts of sediment and debris, a filtering device is generally installed at the end of the suction pipe. It is strictly prohibited to remove the filtering device when absorbing water. If the water source is shallow, it is necessary to dig deeper at the suction point in advance to ensure that there are no impurities or air intake. The water pumps of different sprinkler trucks have different requirements for the water source. The clear water pump requires that there should be no impurities in the water, while the turbid water pump requires that there should be no stones or excessive sediment in the water.
2. Add water intake
Before each suction of the centrifugal water pump, a certain amount of water must be added to the pump, and after adding, the water inlet must be closed. When using a self-priming water pump for the first time, it is necessary to add water, and there is no need to add water in the future.
3. Vacuum is required for the inlet pipe
When absorbing water, the inlet pipe system must maintain a certain degree of vacuum in order to suck water into the tank. The inlet pipe system must be sealed reliably, the hose must not be damaged, and the hard pipe must not have cracks, otherwise there will be air leakage, which will result in the inability to suction water.
4. Parking in gear
The power take-off device of the sprinkler truck must be engaged when parking, whether before absorbing water or spraying water.
5. Winter water release
Before winter arrives, the water in the water pump and pipes should be emptied to prevent freezing and cracking. In northern China, construction is generally not carried out in severe winter, so after the construction is completed, the water in the water pump and pipe should be immediately drained to prevent future problems.
6. Precautions for watering
The position of the sprinkler head in front of the sprinkler is relatively low, close to the ground, and the spraying pressure is high, which can be used to flush the road surface; The position of the rear nozzle is relatively high (usually one on each side of the sprinkler truck), and the sprinkler surface is wide, which can be used for road construction watering. When using the rear nozzle, the front nozzle should be closed; When using an adjustable nozzle for spraying water, the spraying width can be adjusted as needed. The wider the watering width, the less overlap in the middle, and the more uniform the watering density.
7. Lubrication and fastening
During use, it is necessary to regularly lubricate the lubrication points of the transmission assembly and tighten the connection points frequently to ensure normal use.
8. Regular discharge of pollutants
The water tank of the sprinkler truck is equipped 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 switch should be turned on regularly to remove any debris accumulated in the tank until the water becomes clear.
