What are the precautions for the daily maintenance and repair of water sprinkler trucks?

To ensure the water spraying effect of the water sprinkler truck and prevent the filter from getting clogged, the interior of the tank should be cleaned frequently to discharge the sediment.

2. Regularly inspect the pipeline system, valves and nozzles for any faults. If any faults are found, replace them in a timely manner.

When changing the gear oil in a car's transmission, the gear oil should be drained from the side power take-off.

4. The drive shaft of the pump should be lubricated with oil regularly and the connection of the drive shaft should be inspected.

5. Regularly check the sealing condition of the switch and the suction hose. If leakage is found, the seal should be repaired or replaced.

6. Regularly check the fixation conditions of the water tank, pump frame and brackets. All nuts should be tightened to ensure a firm and reliable connection.

7. Regularly check the connection between the power take-off and the water pump. Ensure the connection is reliable and the operation is normal. If the water pump shaft of the power take-off leaks oil during use, the seal should be replaced.

After the water pump is drained, the drain plug should be tightly closed to ensure a seal; otherwise, it will affect the water suction of the water pump.

9. The paint on the can must not come into contact with gasoline or diesel, as this will accelerate the damage of the paint. Regularly check the quality of the paint on the can. When the paint is severely damaged, it should be replenished immediately to prevent the can from rusting.

10. The filter screen of the pump inlet filter should be disassembled and cleaned frequently to prevent dirt from clogging it, which may affect the pump's water suction and flow rate.

11. Due to the rubber pad between the tank and the vehicle beam, as the rubber deforms and the weight of the tank increases, the U-bolts become loose. After the vehicle is heavily loaded, the U-bolts must be tightened regularly, especially for new vehicles.
