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.

Welding Recondition is the best way to reduce cost through increase working life of your equipment. Take Vertical Roll Mill for example, the Coal Vertical Roll Mill (VRM) is an air scanning, medium speed vertical mill with an integrated classifier. It pulverizes coal by applying a hydraulically loaded grinding pressure through three grinding rolls to a rotating bed of coal. The grinding pressure can be adjusted to take into account changes in coal grindability and desired product fineness.
Working principle
The raw material is uniformly fed through the feeder at the bottom of the hopper, and then raised to a suitable height by the bucket elevator, and then sent to the mill through the feeding pipe for grinding, and the ground material enters the powder classifier and is produced by the hot air furnace. Hot air, at the same time dry and grade the material, the unqualified material is poured into the grinding, the qualified fine powder is sent to the powder collector, and then transported to storage. Through the conveyor.
Application
Can be widely used in cement, power, metallurgy, chemical, non-metallic minerals and other industries. It is used to grind granular and powdered materials into powders with the required fineness.
Introduction
It can cover the grinding machine table of various sizes and styles. We can rebuild the table internally or on site according to your needs. We also offer cast steel table replacement and a suitable overlapping section to ensure fit.
