Winter Sprinkler Maintenance Guide
Winter maintenance strategy for sprinkler trucks:
The first step is to add antifreeze.
The antifreeze and oil of the vehicle engine should be replaced promptly with a grade suitable for the local temperature, and a suitable high-quality antifreeze should be selected to avoid unnecessary losses.
Step two, open the ball valve.
Drain the remaining water in the tank and pipeline: Open the pipeline direct ball valve next to the three-way ball valve, and open the front flushing, rear spraying, side spraying, and water cannon ball valves to drain the remaining water.
Step three, empty the remaining water in the pump
Open the waterproof gate of the pump, drain the water, and place the drain valve below the forward port of the pump (as shown in the figure on the right). After the liquid in the pump is emptied, it is necessary to inject water into the pump before the next use.
Reminder:
Dear dust suppression truck/sprinkler truck users, please use dust suppression trucks/sprinklers in cold and freezing weather
When using a water truck, please pay attention to the following:
1. Please replace the antifreeze that meets the local temperature to prevent the water tank from freezing.
2. After using the car every day, please open the ball valve switch of the entire vehicle to drain water to prevent the water pump from running
Freeze crack the ball valve to avoid unnecessary damage.
When using the car the next day, the water pump needs to be filled with water before opening the power take-off to pump water.
In winter, please pay special attention to the following for sprinkler truck customers:
1. Replace the appropriate grade of antifreeze;
2. After using the car every day, turn on all ball valve switches and drain the water completely, especially the small wrench on the water pump (located at the end)
Otherwise, it is easy to cause damage to the water pump, ball valve or pipeline, resulting in unnecessary losses and troubles;
3. If using the car for pumping operations the next day, be sure to add a water pump to inject water, otherwise it is easy to dry burn and damage the water pump!!!
After draining the water, it is best to keep all valves in the open position to avoid the risk of air blockage caused by one cold and one hot situation
Ball valve and pipeline cracking!!!
Pay special attention to the following diagram, ensuring that there is no water in the pipeline, no water in the pump, and the ball valve is half open!!!
