Sprinklers - Top Ten Tips for Handling Sprinkler Operation

(1) The sprinkler should be as close as possible to the operating point and parked. Open the side door of the walk-in box and take out the water-absorbing rubber hose so that it swings back without bending. Pull the water-absorbing hose into the water as deep as possible to ensure that the pipe end is always 300mm below the liquid level during the operation. Push the four-way valve handle perpendicular to the floor. Put the transmission into neutral, then start the engine, disengage the clutch, pull the power take-off switch backwards to pull the file, and the pump starts to run. (2) The operator can use the observation mirror on the upper part of the rear head to inform the driver when the liquid level reaches the middle of the sight glass. Colleagues should quickly pull the water suction hose away from the water or close the four-way valve. After closing the hose, place it back in the walkway box and close the side door. Move the sprinkler away from the pumping point (3). The water inlet pipe must be vacuumed to ensure that the inlet pipe system maintains a certain degree of vacuum before it can draw water into the tank. 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 leakage phenomenon, it will result in the situation of not drinking water

(4). Add water Before the centrifugal water pump absorbs water, a certain amount of water must be added to the water pump. After the addition, 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.

(5). Parking stalls Sprinklers must be parked either before or after watering.

(6). Requirements for water sources When the sprinklers use the river ditch or pond as a water source, be careful that all the ends of the suction pipe are not submerged in 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.

(7). Lubrication and fastening In the course of use, lubrication points of the drive assembly must be regularly lubricated, and the joints should be tightened frequently to ensure normal use.

(8). Sprinkler Precautions The front sprayer of the sprinkler is located at a low position and close to the ground. The spray pressure is relatively large and can be used for flushing the road surface. The position of the rear sprayer is relatively high (the sprinkler is generally installed on the left and right sides of the sprinkler), and the spray surface is wider. It can be used for road construction and watering. When using the rear nozzle, the front nozzle should be closed; when using an adjustable nozzle, the width of the water can be adjusted as needed. The wider the sprinkler width, the less the amount of intermediate overlap and the more uniform the sprinkler density.

(9). The sewage tank of the regular sewage sprinkler is provided with a discharge pipe. The inlet 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.

(10).Drainage in winter Before the advent of winter, the water in the pump and the water pipe 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.
