Usually, the micro-irrigation system is the first link composed of water pump, appearance, control valve and filter, and the pipe network composed of the main pipes, branch pipes and capillary pipes responsible for the mission of water distribution and water, and various forms of water supply directly to the root of the crop. The emitter three is somewhat composed.To get more news about Stainless steel filter wire mesh, you can visit resenwiremesh.com official website.
In the meantime, the irrigator is the key equipment in the final stage of the completion of the irrigation mission. It is called the heart in the micro-irrigation system. In order to make the irrigator work normally, the selection and operation functions of the filtration equipment are crucial.
If the selection of the filtering equipment is wrong, the irrigator will be blocked, which will lead to uneven water distribution and system function degradation, and even constitute the entire micro-irrigation system, so that it has to consume a lot of manpower and financial resources to remove the blocking or reconstruction system.
The filter equipment has the following types:
? (1) The trash rack (stainless steel screen) is mainly used in irrigation water sources rich in large volume of debris such as rivers and reservoirs, blocking dead branches, weeds and other large floating objects to avoid miscellaneous The object enters the pool or reservoir. The structure of the trash rack is simple and can be designed and produced according to the actual situation of the water source.
The primary sewage screen (net) is a type of mesh trash rack installed at the water pump inlet of the water source, that is, the primary purification and disposal equipment, which is mainly used for sludges rich in water sources such as water plants, sundries and algae.
? (2) Stacking pool The pool is one of the primary treatment equipment for water purification of irrigation water. Although it is a simple and old water disposal method, it is a useful and economical disposal for the disposal of various water sources. Method, the role of the pool is now two aspects;
v 1 Remove solid matter from the water. When there is too much sediment in the water, the stainless steel mesh filter and the media filter used will be lost due to frequent flushing. In this case, the stacking tank can play a primary filtering role.
v 2 Remove the iron material. The carbon dioxide dissolved in the groundwater, due to the pressure drop in the accumulation tank, the water temperature rises and escapes, and the pH of the water increases, resulting in oxidation and accumulation of iron matter.
(3) Centrifugal filter (also known as sand separator) is mainly used to remove cement sand.
The working principle of the centrifugal filter is the centrifugal force generated by the high-speed rotating water flow, which separates the sand particles and other heavier impurities from the water body. There is no filter screen inside, no detachable parts, and the maintenance protection is very convenient.The sand chamber at the bottom of the centrifugal filter needs to be flushed frequently to prevent the accumulated sediment from being brought into the system again.
For organic matter or impurities with a specific gravity lower than water, the centrifugal filter has a very poor separation effect, and the centrifugal filter only needs to perform the proper purification of water quality within a certain flow range.
? (4) Sand filter is mainly used for pre-stage filtration of organic matter in reservoirs, dams, pathways, rivers and other open water sources.
It uses sand as a filter medium, and the sewage enters the canister through the water inlet, and then reaches the filtering intention through the pore interception and capture between the sand and the stone.
The sand filter is safe and clean, and it is most useful in all filters to dispose of organic and inorganic impurities in the water with uninterrupted water supply.When the organic content in the water exceeds 10 mg/L, the sand filter should be used regardless of the inorganic content.
