Everyone may have just heard about the filter, but I believe everyone will be rusty about his understanding. Today, let's take a detailed look at the basket filter . The basket filter is mainly used for oil or other liquid pipelines. The area of the filter holes in the pipeline is larger than the area of the diameter pipe by about 2 times, far exceeding the Y-type filter and T-type filter. The filtering area of the filter is called a basket filter because it is shaped like a basket. So, what are the maintenance methods for the basket filter ? What are the principles for choosing a filter? Let's understand it with the editor.Phone Use Tpu Screen Protector, Tpu Phone Screen Protector, TPU Screen Protector, TPU Film Sheets
Basket filter maintenance method
1. The core part of the filter is the core part of the filter. The filter core is composed of the filter frame and the stainless steel wire mesh. The stainless steel wire mesh is a very easily damaged component, so it needs special maintenance.
2. After the filter has been working for a period of time, certain impurities will be deposited in the filter core. At this time, the pressure increases and the flow rate will decrease, so the impurities in the filter core need to be removed in time.
3. When cleaning the impurities in the filter core, pay special attention to that the stainless steel wire mesh on the filter core cannot be deformed or damaged, otherwise, if the filter is reinstalled, the purity of the filtered medium is difficult to meet the design requirements In this way, compressors, pumps, instruments and other equipment will be damaged to a certain extent.
4. If stainless steel wire mesh is deformed or damaged, it should be replaced in time.
Filter selection principles
1. Import and Export Path
In principle, the inlet and outlet diameter of the filter cannot be smaller than the inlet diameter of the matching pump. Generally speaking, it should be consistent with the inlet pipe diameter.
2. Nominal pressure
The pressure level of the filter should be determined according to the highest pressure that may occur in the filter line.
3. Selection of the number of holes
For the pore size of the filter, the particle size of the impurities to be intercepted is mainly considered, which is determined according to the process requirements of the media process. The size of the particle size that can be intercepted by various specifications of wire mesh can be queried by the table of "filter specifications".
4. Filter material
The material of the filter is generally selected to be the same as the material of the connected process pipeline. For different service conditions, consider choosing a filter made of cast iron, carbon steel, low alloy steel or stainless steel.
5. Calculation of filter resistance loss
For water filters, at a generally calculated rated flow rate, the pressure loss should be between 0.52 and 1.2 kpa.
Editor's summary: The above is the introduction of the editor on the basket filter maintenance method and the principle of filter purchase. After reading this article, how should the basket filter be maintained, cleaned, and purchased? Have a very comprehensive understanding of it.
