Why does an automatic backwash filter vibrate heavily during flushing?
Thread Content
The backwash filter vibrates heavily during backwashing – have other sailors encountered this issue? How did you solve it? After the backwash drain valve was closed, it began to vibrate accompanied by loud noises. The noise stops once the oil inlet valve is opened; this is the case every time a filter is flushed. I hope fellow sailors can help analyze this
The crude oil is very dirty, so it needs to be washed frequently, about once every 20 minutes.
What type of backwash filter is it? Are there any photos?
The pressure difference is too high; try reducing the cleaning time to 10 minutes each time
Has the problem been resolved? Is the flushing medium filtered oil or nitrogen?
This situation is quite common, mainly due to excessive operating pressure and a fast opening/closing speed of the valve!
It wasn’t there before; it appeared after some time of use. This indicates that the filter elements are quite clogged, which is causing a large pressure difference across the filter
