Security filter issue
Thread Content
The security filter used to run normally, but because of the large operating pressure difference, the filter element was replaced, and a problem occurred. Back pressure appeared during operation. What are the possible reasons? This post was last edited by hw197358 on 2009-4-4 20:11 ]
What does backpressure mean? Is the outlet water pressure of the security filter higher than the inlet water pressure? If this situation is impossible, it is recommended to replace the pressure gauge. It should be that the pressure gauge is broken. It is easily broken due to vibration in front of the high-pressure pump. It may be that the origin is not 0. This post was last written by li * Edited by ch1968 at 2009-3-14 10:12 ]
Agree with the opinion above, it is best to replace it with a shock-resistant pressure gauge
I also judged that there was something wrong with the watch.
Something that is obviously impossible means a problem
If you analyze the reasons more, they can be solved.
What is the pressure of the water coming out of the fine sand filter? Generally, this value is set.
It is best to remove the security filter and see if there is any problem with the filter element.
I guess the filter I bought is not good, and now the water treatment company is looking for bargains to sell to the owners.
Agree with LS. If there is no problem with the filter element, then it is probably the meter.
Replace the shock-resistant pressure gauge and see if this phenomenon should not occur.
It should be a problem with the pressure gauge. It's impossible for the outlet water pressure to be higher than the inlet water pressure.
It must be a problem with the pressure gauge.
Check the filter element first. If there is no problem, then there is definitely something wrong with the watch... I guess the watch is broken due to shock.
I also encountered this problem. The pressure gauge was replaced, the filter element was replaced, and the system was adjusted later, but it just didn't work, and it was still back pressure.
