Abstract
The invention relates to an oil bearing expansion machine capable of monitoring oil leakage. The oil bearing expansion machine comprises a machine body. Sealing covers used for isolating process gas from lubricating oil are arranged at the two ends of the machine body respectively. A partition plate is arranged between each sealing cover and the machine body. The sealing covers, the partition plates and the two ends of the machine body are each provided with a sealing gas inlet and an oil leakage monitoring hole spaced in the circumferential direction and correspondingly communicated. Ball valves are arranged on hole openings of the sealing gas inlet and the oil leakage monitoring hole in the two ends of the machine body respectively. By means of the oil bearing expansion machine, the lubricating oil in the sealing covers can be monitored and prevented from entering the process gas, so that safety performance is improved, and maintenance cost is reduced.

Background technology
Decompressor realizes middle-size and small-size air separation plant to the crucial unit manufacturing large air separation plant transition, therefore the bearing lubrication mode in air separation plant develops into oil lubrication by gas lubrication, has the advantages such as bearing capacity is large, reliability is high, the life-span is long, maintenance work is few; If but the sealing shroud in oil bearing decompressor lost efficacy, will make lubricating oil from sealing shroud leak in impeller with process gas mix, the lighter causes equipment to freeze the accident of stopping, severe one causes the major accident of blast, and during maintenance, want heat exchanger or fractionating column to carry out cleaning blowing, expense is very expensive, for this reason, we have developed a kind of oil bearing decompressor monitoring leakage of oil, dynamic monitoring can be carried out to the lubricating oil in sealing shroud, prevention lubricating oil enters in process gas, thus improves security performance, saves maintenance cost.
Summary of the invention
The present invention seeks to provide a kind of oil bearing decompressor monitoring leakage of oil to overcome the deficiencies in the prior art, dynamic monitoring can be carried out to the lubricating oil in sealing shroud, prevention lubricating oil enters in process gas, thus improves security performance, saves maintenance cost.
For achieving the above object, the technical solution used in the present invention is: a kind of oil bearing decompressor monitoring leakage of oil, comprises fuselage; The two ends of described fuselage are respectively arranged with the sealing shroud for isolated process gas and lubricating oil; Dividing plate is respectively arranged with between each described sealing shroud and fuselage; Described sealing shroud is provided with spaced first air admission hole of circumferencial direction and the first monitoring holes; Described dividing plate is provided with second air admission hole placed corresponding to the first air admission hole and the first monitoring holes and the second monitoring holes; The two ends of described fuselage are respectively arranged with three air admission hole placed corresponding to the second air admission hole and the second monitoring holes and the 3rd monitoring holes; The first air admission hole, the second air admission hole, the 3rd air inlet that described fuselage is often held all form one article of blanket gas air admission hole, and the first monitoring holes, the second monitoring holes, the 3rd monitoring holes all form one article and state leakage of oil monitoring holes; The blanket gas air admission hole at described fuselage two ends and the aperture place of leakage of oil monitoring holes are respectively arranged with ball valve.
Preferably, the medium being convenient to observe oil mass or the analytical equipment checking oil mass is provided with in described leakage of oil monitoring holes.
Preferably, described blanket gas air admission hole and the setting of 180 degree, leakage of oil monitoring holes interval.
