Description

Technical Field

[0001] The utility model relates to the technical field of transmitter maintenance, in particular to a rapid maintenance device for a novel intelligent transmitter. Background Art

[0002] Chemical companies currently use pressure transmitters and differential pressure transmitters more commonly. Inspection and maintenance personnel need to frequently dismantle the transmitter cover for inspection, double flange calibration, and other work. During the inspection and maintenance process, the transmitter back end is often difficult to open. When calibrating the double flange, the double flange and the pressure diaphragm box bolts are frequently disassembled and assembled, which affects the work efficiency. Therefore, a new type of intelligent transmitter rapid maintenance device is needed.

[0003] When the maintenance personnel disassemble the transmitter end cover for inspection, they may find that the threads of the rear end cover are corroded and rusted, there are impurities in the thread gap, and even the thread thread is misplaced. There are currently two common ways to open the cover: first, use a long-handled screwdriver or wrench to loosen the end cover at the cross groove of the end cover. Because the cross groove has a certain arc and the force-bearing surface is small, it is not convenient to open the cover, and even excessive force may cause slipping, which poses a certain safety risk to the maintenance personnel; secondly, when the end cover is stuck, use a pipe clamp to remove the end cover. This method damages the end cover shell and is irreversible. Transmitter calibration is also a common phenomenon in the maintenance process. Currently, there are many single-flange pressure transmitters and double-flange liquid level transmitters in use. During the calibration process, the calibrator is connected to the corresponding size flange surface and then connected to the calibrated membrane box. The connection process is fixed with 4 bolts. When batch calibration is performed, the bolts are frequently removed, affecting the calibration efficiency. Utility Model Content
