    York YK seal oil usage

    I am working with an owner who has a new York/JCI 850 Ton, Variable Speed centrifugal chiller (model YK). The compressor shaft seal is a “wet seal” and I understand that this requires some oil to pass through the seal. York service data indicates that any oil usage under 2 oz every 14 days is acceptable. This seems like a good bit of oil to me.

    Does anyone have any experience with these machines? And if so what type of oil usage rate have you experienced?

    Thanks

    The new style shaft seal on the York centrifugal have an average seal leak rate of 90 ml/month. Unfortunately York officially does not consider a seal to be leaking unless it fills the 750ml bottle in 250 hrs of operation.

    Where can one find the York specs for YK shaft seal oil usage? I've been thumbing through all my manuals, and can't find it?

    One thing to consider also , is the amount of idle / off-line time vs. run time . Also be sure the seal lubrication function is enabled .

    There is also a SB out there that states if a machine is idle or in storage to manually lubricate and manually rotate the shaft .

    Yes long term storage SB. Keeps stuff from drying out.
    We got involved in a power plant that was moved Mississippi area to SE NM , old Enron plant. There were six 2000 t YK style E , 4160 VAC chillers that had never been started. They were around five years old. Had not been rolled or oil pumped. We changed the shaft seals and pump oil thru the oil filter to about twenty psi and could hand roll them. They are still running with minimal problems.
