- Water Source Requirements
- When using natural sources like rivers or ponds for a water truck, ensure the suction pipe’s end is fully submerged. To avoid drawing in stones, excess mud, or floating debris, the pipe’s end is usually equipped with a filter, which should never be removed. It’s recommended to fill the tank from deeper parts of the water source. If the water is shallow, dig deeper at the intake point to ensure clean water without debris or air being sucked into the pump. Different water pumps have different requirements for water purity: clean water pumps need water free of impurities, while dirty water pumps can handle some sediment but not stones or excessive mud.
- Maintain Vacuum in the Water Intake System
- For a sanitation water truck to draw water, the intake pipe system must maintain a certain level of vacuum. The system must be well-sealed, with no damage to the flexible hose or cracks in the hard pipe. Otherwise, air leaks can prevent water from being drawn into the tank.
- Priming the Pump Before Water Intake
- Centrifugal water truck pumps require priming by adding water to the pump before every water intake. After priming, ensure the water inlet is closed. For self-priming pumps, you only need to prime them the first time; afterward, priming is not necessary.
- Drain Water in Winter
- Before winter arrives, drain the water from the pump and pipes to prevent freezing and cracking. In northern regions, where construction stops during severe winters, ensure that the water is fully drained from the system after operations are completed to avoid future damage.
- Engage Parking Gear When Stationary
- Whether filling the tank or spraying water, always engage the power take-off gear when the water truck is stationary.
- Maintenance After Returning from Work
- Clean the water truck thoroughly. Check and refill fuel, lubricants, and coolant. Inspect the tension of belts on components such as the fan and water pump, adjusting if necessary. Check tire pressure and the seals on gearboxes. Organize and check any accessories and tools that are stored with the vehicle.
- Regular Drainage of the Water Tank
- The water tank of a sanitation water truck has a drainage pipe, with the intake located at the lowest point of the tank. After a period of use, open the drainage valve periodically to release any accumulated debris from the tank until the water runs clear.
By following these practices, you can extend the operational lifespan of a water truck and maintain its efficiency over time.
