Sprinkler tips

1. requirements for water
When sprinkler use of rivers, ponds as water, note that all suction pipe end into the water. To avoid inhalation of large stones or sand, floating debris, and generally includes suction pipe end filter, water filtration devices is strictly prohibited when removed. If the water is shallow, requires water to dig deeper, to ensure that no debris and not into the air. Different sprinkler pumps the water itself is different, fresh water pump requires no impurities in the water, turbid water pump requires cannot have too many rocks and sediment in the water.
2. Add water
Before each of centrifugal water pump suction must be added with a certain volume of water to the pump, adds must be turned off after adding water. Self priming water pump when used for the first time, you need to add water, you do not need to add water again later.
3. the inlet pipe must be vacuum
Water inlet pipe system must maintain a certain degree of vacuum, pumping water in tank. Water systems must be reliable, hoses should not be damaged, hard tube cannot crack or leakage, also caused no water absorption.
4. the parking gear
Sprinklers either before the water, still in front of the water, power take off unit gear has to be at the Park.
5. winter water
Before the arrival of winter, water pumps and pipes in the water should be emptied to prevent cracking. North China winter construction no longer, therefore, upon completion of the construction, the water emptying pumps and pipes immediately, in case of trouble.
6. water considerations
Water front lower nozzle, close to the ground, spraying pressure, can be used for washing pavements; higher nozzle after (the sprinkler nozzle after each one) and sprinkled the water is wide, can be used for watering of road construction, when the nozzle after use should be the front nozzle close; when using the adjustable nozzle sprinkler, watering duration can be adjusted as needed. Sprinkling width and wider, less overlap and more uniform water density.
7. lubrication and fastening
Used to lubricate the drive Assembly in regular intervals during each lubrication point, often tight junction points, to ensure that the normal use.
8. the periodic blowdown
Sprinkler water storage tank with drain pipe, it tube imports as the bottom of the water tank. After a period of use, you should periodically open the drain pipe switch, the exclusion of accumulated debris in tank until the water becomes clear.
