    reciprocating compressor bearing wear



    Hello everyone. i have read a article regarding to reciprocating compressor bearing wear but something i have don't understand !
    The article stated that Temperature of the discharge valve above 350F ( 177°C ) the oil will start to break down, causing accelerated bear wear . The article did not mention whether want to change new compressor oil or remain using after we troubleshoot and solve the problem .Could anybody tell me what should i do when face this type of problem !
    Any advice would be greatly appreciated .

    oilzee regard

    When oil reach that temperature it becomes carbonized and smell. You could make oil acid test and check color of oil, and accordingly, change oil and fit burn out filter-dryer in suction and discharge pipe.
    In fact, you should proceed like you heaved burn-out.

    Re: reciprocating compressor bearing wear

    Hi Oilzee,
    Might be an idea to send a sample away for analysis. They can tell you carbon content, acid levels, and presence of any wear metals ie bearing, valve, casting, piston rings etc.
    I was told by a lubrication chemist that mineral life should be halved every 10c above 80c ie. That`s ok in theory but i`ve not meet a customer yet who`ll pay for that.
    Regards,
    Glenn
