1. Requirements for Water Sources When a watering vehicle uses a river ditch or a pond as a water source, be careful that all the ends of the suction pipe do not enter the water. In order to avoid inhaling stones or more sand and drift debris, the suction pipe end is generally provided with a filtering device, and it is forbidden to remove the filtering device during the water absorption. If the water source is shallow, it is necessary to dig up the water absorption area in advance so as to ensure that it does not contain impurities and air. The water pump requirements for different sprinklers are different. The clean water pump requires no impurities in the water. The turbid water pump requires no stones and excessive sediment in the water. Daily maintenance and maintenance (1) Car chassis and supporting pump maintenance according to the corresponding instructions for use.

2. Adding water Before the centrifugal water pump absorbs water, it must add a certain amount of water to the water pump. After the water pump is added, the water inlet must be closed. When the self-priming pump is used for the first time, it is necessary to add water, and it is unnecessary to add water afterwards.
3. The water inlet pipe must be vacuumed The water inlet pipe system must maintain a certain degree of vacuum before it can suck water into the tank. The inlet pipe system must be sealed reliably, the hose can not be damaged, the hard pipe can not have cracks, otherwise it will have a phenomenon of air leakage, which will result in the situation that it cannot suck water.
4. Parking stalls Before the sprinkler is water-absorbed or before the water is sprayed, the power-lifting device must be parked.
5. Winter watering Before the advent of winter, the water in the pumps and pipes should be vented to prevent freezing. In northern China, which is generally no longer under construction during the harsh winter season, the water in the pumps and pipes will be drained immediately after construction is completed to prevent future problems.
6. Sprinkler Precautions The front sprayer of the sprinkler is located at a low position and close to the ground. The spray pressure is greater and can be used for flushing the road surface. The rear nozzle is located at a higher position (the sprinkler head is generally installed on the left and right sides respectively), and the sprinkler surface is wide. When spraying water on highway construction, the front nozzle should be closed when the rear nozzle is used, and the width of the water can be adjusted as needed when using the adjustable nozzle. The wider the sprinkler width, the less the amount of intermediate overlap and the more uniform the sprinkler density.
7. Lubrication and fastening Lubricate the lubrication points of the transmission assembly regularly during use, and frequently tighten the connection points to ensure normal use.
8. Regular discharge of sewage The tank of the sprinkler is provided with a sewage pipe. The entrance of the pipe is the lowest point of the tank. After a period of use, the discharge pipe switch should be opened periodically to remove the accumulated debris from the tank until the water becomes clear.
(2) Before use, the vehicle should be worn out according to the requirements of the vehicle's instructions.
(3) When the long-distance transfer is consigned, there should be a fixed anti-skid device around the vehicle, and there should be more than 200mm clearance around the vehicle. If the self-conversion is performed, the front nozzle and rear sprinkler should be removed to prevent loosening.
(4) Check regularly whether there is any clogging in the holes and mouths, and clean up the debris when it is found to be clogged.
(5) After each shift is completed, the oil should be cleaned, the pipelines must be neatly arranged, and the scene should be cleaned up.
(6) If the vehicle is not used for a long time or stored in winter, the remaining water in the tank, the pump and the pipeline shall be drained, and it shall be parked in the carport during storage and wipe clean to avoid exposure to rain and rain.
