Bearing wear issue
Thread Content
One of the devices I am responsible for managing is a multi-stage centrifugal pump, equipped with 7314 bearings. The bearing at the outlet end wears out its retainer while in operation; one bearing fails every two weeks or so. What could be the reason for this?
Reply to 1# Phoenix: 1. Is there any issue with the quality of the bearings? 2. Is the axial play during installation within normal limits? 3. Are the installation position of the thrust disc, its stress conditions, as well as the condition of the balance disc (balance drum) and balance pipes all normal?
Reply to 1# Phoenix: 1. Inspect the quality of the bearings. 2. Check whether the axial play is within normal limits during installation, as well as whether the bearing clearance is normal. 3. Examine the condition of the balance disk, balance drum, and balance pipes
This problem! ! We just resolved this issue on our end! ! ! We also meet once every two weeks on average! Install it for direct high temperature of 60-80! ! First, consider whether your bearing is genuine! ! Our pumps are double-ended! ! Two bearing housings! ! The rear bearing housing is the 7314 bearing! ! !
Reply to 4#: When it comes to Rigdon, mine is a multi-stage centrifugal pump with dual bearings; SKF bearings are used, so the quality should be fine. Please let those above tell me how to proceed!
First check the levelness and verticality, then see if the shaft is bent
Just like what was said upstairs! First, check the levelness and perpendicularity; simply examine whether there are any unevenities on your bearing housings. Next, measure the gap between the bearings – for SKF bearings, it is necessary to adjust this gap. It is recommended that you try using bearings from Harbin, or add a 5-micron thick copper sheet between the SKF bearings! ! !
They are all mechanical experts, so I won’t talk about mechanics. What is the current status of bearing lubrication?
