Is there any adujstable control regulating valve (flow) INSTALLED...to maintain vacuum set in the oil tank

 

The unit since commissioning is running with slight positive pressure at LO tank. The unit was handover in that condition to Operation team.
Last LTPI we checked everything internally. Changed cartridge filter.
After startup still it was same. Adjustable valve was tried after startup, but there was no any change in vacuum. After that never got a chance to check anything.
Unit still as its is because it never reached the trip point of 50mmh20 at LO tank

 

To check bypass line we need shutdown as it's internally located.
as the system is new for operation, We are not very familiar with the mechanics. We will try to do with pid support in next opportunity.
Last time most of the things was checked and verified by mechanical maintenance team.

 

Okay
Thx for keepin us updated...
