The self-made tool of the No. 1 Gas Production Plant of North China Oil and Gas Branch obtained a national patent

China Petrochemical News Network recently, the "graphite bearing disassembly tool" independently developed by the purification plant of the No.

As the only professional gas field produced water treatment team in Daniudi Gas Field, the purification plant currently has more than 60 canned motor pumps, which are important power equipment for the station.

In the prior art, the disassembly of graphite bearings generally depends on a puller, but for bearings with a large installation depth, due to the limited length of the front paws of the puller, they cannot reach the bottom of the bearing to block the bearing, and reaction force support is required during operation.

Another type of impact type disassembly tool is easy to damage the graphite bearing when it has a small sticking point after being penetrated into the graphite bearing.

The tool developed this time is a clamp-type disassembly tool.

It is understood that in addition to the petroleum industry, canned motor pumps are often used when transporting toxic and harmful liquids in the pharmaceutical industry, and this application has a broad prospect.
