Whats the V wire screen? Article content is reproduced from  ZHEHAN FILTER , writer：Snow V wire screen is also called  wedge wire screen   because its body consists of V-shaped stainless steel wire, so many people call it  V wire screen. It is widely used in the oil, gas, water well and sand control industry in the worldwide. Its position in the well industry is especially prominent, and it is the most popular type of filter elements in the various liquid filtration process. The full-welded v wire screen adopts a full-wound welding production process and is welded with a special trapezoidal wire winding on a set of support wires arranged in a circumferential arrangement. The whole welding ensures the strict continuous integrity of the product, which makes it form an ideal gap size and has the capability of bearing high pressure in maximum quantity. The material of the v wire screen mainly includes th...

Wedge wire filter      General Wedge wire is a welded steel structure, mainly used for filtration, separation and retention media. It consists of surface profiles, usually V-shaped, that are resistance welded onto support profiles. The distance between the surface profiles is controlled very accurately, as it forms the slot through which the filtrate flows. In case of V-shaped surface profiles conical slots are created (as shown on figure). Filtrations Direction The direction of the flow is determined by the position of the surface profiles in relation to the support profiles. Wedge wire screens are either flow-out-to-in (FOTI) or flow-in-to-out (FITO) Advantages Wedge wire has the following advantages: Non-clogging: the continuous slot formed by the V-shaped surface wires ensures a two-point contact between the particles and the slot, which minimizes clogging. High-precision slot sizes: precise slot sizes are available to meet customer´s requi...

Rainwater filter 1. the importance of rainwater treatment Rainwater is part of the water cycle and is also an invaluable source of water. The use of rainwater for treatment in urban use is a way to address water shortages. With the rapid development of China's urbanization process, the coverage of urban cement concrete is very high. When it encounters short-term and high-intensity rainstorms, the drainage is not timely and it is easy to form urban interiors. If you can collect rainwater, you can greatly alleviate the guilt. Therefore, rainwater treatment has a very important meaning. 2. the status quo of rainwater treatment Germany, Denmark, Japan and other countries have carried out relatively early rainwater treatment and achieved good results. The rainwater is collected through the rainwater collection pipe network, and then treated with certain technical measures to make the rainwater quality reach a certain standard of use, as a city miscellaneous water source. Dome...

Filtration,  Filter,   Filter element Yesterday I wrote an article about the candle filter, still no response, because my blog is little visitors, it seems that there are only a hundred people, for the world's billions of people, it is really insignificant, but I still insist on blogging Because I found out that I started to like this way. I think, many people may not be familiar with filtering. They only know that cars need to be replaced with air filters, oil filters, etc. People don't know the meaning of filtering in our lives, because I was such a person from the beginning. However, since I was engaged in the manufacture and production of stainless steel filter cartridges, my world has been expanded for a moment, and I know that things that are very inconspicuous also need to be filtered. The filtration in life can be seen everywhere, fountains, tap water, fish tanks, car air filters mentioned above, water purifiers, etc. The water circulation system of fountai...

Filter pressure drop design Article content is reproduced from  ZHEHAN FILTER , writer：Snow Filter pressure drop is what we should know when we use the product. What is it? The term “Pressure Drop” gets used a lot in the indoor air quality industry, but it isn’t always well defined. The Wikipedia definition of pressure drop is as follows: Pressure drop is a term used to describe the decrease in pressure from one point in a pipe or tube to another point downstream. When air is drawn through a system with a filter installed, that filter will create some resistance to the airflow. As a result, the difference in air pressure in the ductwork on one side of the filter versus the other side of the filter is what professionals refer to as pressure drop. The filter element should be designed to have a large flow rate and a small pressure drop. 1. Filter pressure drop of woven mesh filter The filter pressure drop of the woven wire mesh filter is calculated according to the ...

Wedge wire screen open area Article content is reproduced from ZHEHAN FILTER , writer：Snow The Wedge wire screen open area is a factor we often overlook, in fact, the opening ratio is a very important parameter for our users, especially for customers who use the wedge wire screen for filtration or separation for the first time, it is more important to consider this impact. How is the opening ratio of the wedge wire screen calculated? The opening ratio of the wedge wire screen can be understood as the ratio of the slot size. F: Opening ratio x: width of the wedge wire n: Slot size F=n/(n+a)x100% ADVANTAGE The wedge wire screen open area is higher than weave wire mesh filter media, this is also an important reason why we chose it. 1.  High open area, the flow rate of treated water will be greater. 2.  High open area, pressure loss will be smaller. reduced energy consumption while ensuring our economic benefits. 3.  V-shaped wire, will no...
