Significance of industrial peristaltic pump in water quality detection

With the increase of the world's population and the development of industrial and agricultural production,water consumption is increasing.At the same time,due to human production and life,surface and underground water pollution and deterioration of water quality,the limited water resources are more strained.In the case of such a shortage of water resources,we should cherish water resources more and do a good job in the inspection department to protect people's health.Water inspection is about the livelihood of the metabolism,not to be underestimated,this is the important significance of industrial peristaltic pump.

One,water quality inspection of the main test items

Water quality inspection refers to the unified time or improper inspection of chemical substances,suspended matter,sediment and aquatic ecosystem in water,the determination of the type,concentration and change trend of pollutants in water,and the evaluation of water quality,etc.The main monitoring items are mainly divided into:comprehensive indicators reflecting water quality,such as temperature,chroma,turbidity,pH value,conductivity,suspended solids,dissolved oxygen,chemical oxygen demand,etc.Certain toxic substances,such as phenol,cyanide,arsenic,lead,chromium,cadmium,mercury and organic pesticides.

Two,water quality sampler type

Water sampler is a device for collecting water samples.According to the working form,it can be divided into manual sampler,automatic water quality sampler and on-line automatic sampler.Water quality sampler mainly includes automatic water quality sampler and on-line automatic sampler.Applicable to environmental monitoring stations at all levels,sewage treatment plants,water resources management,water resources and research institutions,automatic sampling of industrial pollution discharge outlets,rivers,rivers,lakes,oceans and other water samples.

Three,the basic principle of water sampling

The machine is driven by reliable peristaltic pump and hybrid step regulation.Industrial peristaltic pumps are like squeezing a fluid-filled hose with your finger.The finger slides forward and the fluid in the tube moves forward.Peristaltic pumps work the same way,but with rollers instead of fingers.Alternately squeeze and loosen the pump's elastic conveyor hose to pump fluid in.Just like holding a hose with two fingers,when the fingers move,negative pressure forms inside the tube and liquid flows.
