Problems with the filter
Thread Content
The basket filter installed in front of the pressure regulating valve on the pressure regulating skid is supplied and installed separately. The rated flow rate indicated above is 1500 m3/h, but the actual flow rate here is 4000 m3/h, **which exceeds it. I was wondering whether the filter here can still be used in actual use? If it can be used, what are the negative effects during its use? For example, will the filter elements need to be replaced frequently?
The use of such a filter is intended to enhance the filtering capacity; however, the actual flux is higher than designed, which reduces the processing capacity. Additionally, the resistance of the filter affects the flow rate.
The flow rate will definitely be low, and the pressure will also be high. You can try to enlarge the holes on the filter cartridge; this allows the mesh size of the filter to be reduced slightly, without compromising the filtering efficiency
It has an impact: first, the pressure difference will increase, the filter elements will need to be replaced more frequently, and there is even a possibility of blockage or damage to the filter mesh.
Add more filters, and keep a few as spares
Excessive flow not only easily overloads the filter screen but also reduces its efficiency, making it more prone to clogging and failure, which allows impurities to enter the pump and cause damage to the pump impeller; be careful!
The filter here can be used, but the following issues will occur: 1. The flow rate is only 1500 cubic feet per hour, which is not enough to reach a flow rate of 4000. To achieve the desired flow rate, it is recommended to connect 2 more filters in parallel, so that all 3 are used simultaneously; this way, the required flow rate can be achieved while also allowing for filter replacement without shutting down the system. A flux of 2.4000 requires a filter with a capacity of 1500 cubic feet per hour; this leads to the need to replace and clean the filter elements on a frequent basis, and it also results in excessive pressure loss within the system as well as high energy consumption ； It’s like putting a bowl of rice (which represents impurities) into a disposable cup and a large basin (the cup and basin acting as filters). From a professional perspective, it is not recommended to reduce the filtration precision of the filter (3rd floor)
It cannot be used; it needs to be redesigned and replaced. Otherwise, it will affect the normal operation of the equipment and increase the difficulty of operation.
