Sprinklers have three major requirements for water quality?
1. Add water diversion: Each time the centrifugal pump absorbs water, a certain amount of diversion must be added to the 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.
2. Requirements for water sources: When the sprinklers use the river ditch or pond as a water source, pay attention to that all the ends of the suction pipe are not in 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.
3. The inlet pipe must be vacuumed: The water inlet pipe system must maintain a certain degree of vacuum before the water can be sucked 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.

High pressure carbon steel with
zinc trivalent anti-corrosion coating per J514 standard. Flareless
compression tube fittings come fully assembled with tube Nuts and
ferrules. These fittings are used with hydraulic tubing that cannot or
does not need to be flared. Product Details Flareless Compression Tube
Fittings The male fitting has straight threads and a 24° seat. The
female connection uses a tube, tube nut, and bite-type sleeve. When the
tube nut is tightened the seal is made between the sleeve and 24° seat. A
seal is also made between the sleeve and the tubing. The threads hold
the connection mechanically.
