[Asia Fluid Network News] deep well in the market a lot of types of pumps, only from the manual to see very bad distinction between product features. Then the customer how to choose products in the product selection? Next, we will summarize some of the predecessors deep pump selection experience to share the product selection should pay attention to the matter. Deep well submersible pump selection guidance Deep well submersible pump how to choose 1, suggesting well water content of more than one ten thousandth of wells: It is not appropriate to install the use of deep well pump. Because well water content is too large, such as more than 0.1%, will accelerate the wear of rubber bearings, causing pump vibration, shorten the pump life. 2. According to the descending depth of the well water level and head loss of the water pipeline: Determine the actual required lift of the well pump, that is, the lift of the well pump, which is equal to the vertical distance (net head) from the water level to the water surface of the tank plus the head of loss. The head of loss is usually 6 - 9% of the net head, usually 1 - 2m. Pump the lowest impeller into the water depth of 1 - 1.5m is appropriate. The total length of the downhole portion of the pump tube shall not exceed the maximum length of the well into which it is specified in the pump instructions. 3, according to the amount of well water: selected well pump flow. Each well has an economically optimal volume of water that should flow at a rate equal to or less than the level at which the well water level drops to half the well depth. When the pumping capacity is greater than the machine water, it will cause the machine wall collapse and siltation, affecting the life of the well; if the pumping is too small, the benefits of the well can not be fully realized. So, the best way is to pump wells pumping test, with the wells may provide the largest amount of water for the selected well pump flow basis. Pump flow to the label number or label on the manual shall prevail. 4, according to the caliper, water quality initial pump: different types of pumps on the diameter of the wells have certain requirements, the maximum size of the pump is less than the caliper 25--50mm. If the borehole skew, the maximum size of the pump should be smaller. In short, the part of the pump body can not close to the inner wall of the well to prevent the pump from damaging the well due to vibrations of the pump. Deep submersible pumps for deep well, hot water wells and the extraction of the ocean can also be used for irrigation and plateau mountain water, factories, railways, mines for drainage. In our country, deep well submersible pump after years of development, more and more suitable for people's production and life. To study it further is the need of the times. Only when the relevant work is done more carefully can its future development be smoother. Related articles: What brand of submersible pumps What are the features and functions of submersible pumps?
Turbidity Analyzer
Turbidity is a measure of the concentration or number of suspended matter or suspended particles in water or other liquids. It is a physical property used to describe the transparency or clarity of a liquid. Liquids with low turbidity are usually clear and transparent, while liquids with high turbidity contain more suspended matter, making them appear cloudy or opaque. The measurement of turbidity requires a turbidity analyzer to complete.
The principle of the turbidity analyzer is the scattering of light. When light passes through the liquid, the suspended matter scatters the light, making the liquid appear cloudy to the observer. The measurement unit of turbidity is usually NTU (Nephelometric Turbidity Units) or FTU (Formazin Turbidity Units), and these units are determined according to specific measurement standards and instruments.
Turbidity meters are important in many fields, especially in water quality monitoring, environmental protection, drinking water treatment and industrial process control. By monitoring and controlling turbidity, it is possible to assess the level of suspended solids in a liquid, ensure water safety and quality, and keep industrial processes functioning properly.
Daruifuno's turbidity meters are all digital, with two types for measuring high turbidity range and low turbidity range. There are four kinds of matching turbidity sensors, and users can choose according to their own needs.
