plate valve failure
plate valve failure
(OP)
hi
we face to a suction plate valve failure as you can see in the below picture.




after inspection,because of effect of cylindrical pin (c2*430) on the discharge valve seat(c2*320) i think the nut(c2*310) didn't tighten firmly and discharge valve guard(c2*360)had rotated but i'm not sure about it.

so have you ever encounter similar problem?do you have any idea about the cause of failure?

this valve is for suction second stage , we changed this valve after compressor overhaul and after 1 month it failed.
driver operating rpm is 600 rpm , suction pressure at 2nd stage is 3.81 Bara , discharge pressure is 5.44 bara.

I am not sure that this would have been the direction I would have taken, but they are happy.
