Problems with the high-level oil tank in centrifugal compressors

This post was last edited by ysk121115 on 2016-4-22 09:03. Is the level gauge for the high-level oil tank in a centrifugal compressor important? Is it necessary? Can it be omitted? Additionally: if necessary, does a level gauge require interlock functionality in addition to alarm settings?
No, but in the event of a sudden power outage and the lubrication pump stopping, it provides protection for the equipment in the absence of lubricant; otherwise, the shaft could get stuck
The high-position fuel tank is still there. It just lacks a fuel tank level gauge
A liquid level gauge for the high-level oil tank in a centrifugal compressor is important and essential. Before starting up, apply oil through the main line; there is no level gauge, making it difficult to monitor the level, and overflow is likely to occur.
Thank you, teacher. One more question: after setting an alarm for the high-level oil tank level gauge, is it necessary to connect it to some kind of interlock as well?
It is also possible to use an overflow tube to check for overflow; a level gauge is not necessarily required
A high-level fuel tank level gauge is not necessary; continuous fuel supply with high-level overflow
We didn’t install a high-level oil tank as per the original design, and as a result, during a power outage across the entire plant, all the bearing shells were burned out
Previously, the level gauge was not put into use, and as a result, the tank overflowed~~~~ Level gauges are indeed necessary; this was evident from the very beginning when the tank was being built
A high-level oil tank must be installed; there is also a coasting time after the machine stops running. If the lubrication pump loses power, the lack of lubrication can cause the bearings to burn out. The liquid level in the high-level oil tank is usually set as a condition for starting the machine.
It’s not necessary. It’s best if there is one. We don’t have that; it’s difficult to control the high oil pressure every time.
