Abstract
A shaft displacement probe sealing member comprises a sealing cavity, a different-diameter joint and a packing extrusion joint; the different-diameter joint and the packing extrusion joint are respectively connected with the two ends of the sealing cavity; the other end of the different-diameter joint is in threaded connection with the rotation equipment box; the other end of the packing extrusion joint is connected with the union joint of an electric appliance flexible pipe; the probe lead-in wire is passed through a sealing member, and is connected with the probe extension line by a probe extension line joint inside the flexible pipe. The member of the utility model can act as both a protective tubing and a sealing member, has sealing function and function for connecting compressor and flexible pipe at the same time, can effectively solves the problem of lubricating oil leakage of shaft displacement probe; and the displacement probe sealing member is designed into an one-piece structure, is very easy for mounting and dismounting, and has a low price; the prior time/labor taking measuring component mounting/dismounting work takes only 2 minutes by the element of the utility model; and the element can be used repeatedly, and needs no change to rotation equipment body.
Description
Technical field
The utility model relates to the sealing technique that rotating machinery axial displacement probe prevents oil leak, is a kind of axial displacement probe Sealing specifically.
Background technique
The axial displacement of rotating machinery is measured, the existing detection system of Bentley company that mostly adopts, and the in-site measurement element is made up of measure probe, prolongation cable, fore-lying device three parts.The axial displacement probe is converted to gap voltage with the axial displacement of compressor, deliver to fore-lying device by prolonging cable, fore-lying device is converted to the mV signal with gap voltage, delivers to the unit detection system that is used to show rotating machinery (compressor) axial displacement, guarantees the safe operation of compressor.After axial displacement probe and compressor main shaft gap were installed and adjusted, its probe lead wire will reach the compressor outside and prolongation cable, fore-lying device link to each other.Existing axial displacement probe lead wire reaches the compressor outside and just seals at its protective tube (terminal box) lining electric consumer lute in or friction tape.Because the electrical equipment lute in is not withstand voltage, the lubricant oil (flue gas) in the equipment has just drained to the equipment outside along the protective tube of axial displacement probe lead wire like this.And the probe lead wire in the protective tube has and mostly is two greatly, like this, and the sealing of more unfavorable clay.Be not suitable for as being used also with " O " type rubber seal and electrical equipment lute in.The lubricant oil that spills had both polluted environment, also existed serious potential safety hazard.Simultaneously, because the long-time immersion oil of sealed insulation friction tape, emulsification is serious, and viscosity is very strong, does not only have the effect of sealing, and very inconvenience during maintenance installation shaft displacement probe, and only cleaning just need take a long time.When each unit maintenance is debugged the installation shaft displacement probe, all will locate to smear the electrical equipment lute in or twine the insulating black adhesive tape sealing at the protective tube (terminal box) of lead-in wire, the maintenance installation is wasted time and energy, and be very inconvenient to the maintenance man.
The model utility content
Technical problem to be solved in the utility model is: the sealing effect that the axial displacement probe is connected with compressor is bad, the lubricant oil that spills is befouling environment both, also there is serious potential safety hazard, and change inconvenience is installed, waste time and energy etc., thereby a kind of have excellent sealing effect and axial displacement easy to loading and unloading, cheap, reusable probe Sealing are provided.
Technical problem of the present utility model adopts following technical proposals to solve:
A kind of axial displacement probe Sealing, form by Seal cage, reducer fitting and packing squeezed joint three parts, described reducer fitting is connected with the Seal cage two ends respectively with the packing squeezed joint, the other end of described reducer fitting is threaded with the rotating machinery casing, the union of the other end connecting circuit bent pipe of described packing squeezed joint, probe lead wire passes Sealing, is connected with the probe elongation line by probe elongation line joint in bent pipe.
An end is provided with inwardly protruded sealing table top in the described Seal cage, and the other end is provided with internal thread.
The utility model be protective tube be again Sealing, have the effect that connects compressor and bent pipe when having seal action again, can effectively solve axial displacement probe lubricant oil leakage of oil problem.And axial displacement probe design of rubber seal is an integral type, and dismounting is very convenient, and is cheap.Originally removing and installing these measuring cells wastes time and energy, and only needs just can deal with problems in 2 minutes now, and can reuse, and the body of rotating machinery is not done any change.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated:
With reference to accompanying drawing, a kind of axial displacement probe Sealing is made up of Seal cage 2, reducer fitting 1 and packing squeezed joint 3 three parts.Reducer fitting 1 and packing squeezed joint 3 are threaded with Seal cage 2 two ends respectively, the other end of reducer fitting 1 is connected with the screw thread 7 of rotating machinery casing, the other end of packing squeezed joint 3 is connected with the union 4 of electrical equipment bent pipe 9, displacement probe 6 is after the inner installation of rotating machinery is adjusted, probe lead wire 10 passes Sealing, is connected with the probe elongation line by probe elongation line joint 8 in bent pipe 9.An end is provided with inwardly protruded sealing table top 5 in the Seal cage 2, sealing principle according to the control valve packing, when probe lead wire 10 passes Seal cage 2, on probe lead wire 10, twine the tetrafluoro packing, the other end of Seal cage 2 is provided with the internal thread 11 that is connected with packing squeezed joint 3, adjust the degree of tightness of packing squeezed joint 3 and internal thread, just can be by packing squeezed joint 3 extruding tetrafluoro packings, adjust the degree of tightness of tetrafluoro packing in Seal cage 2, to reach the requirement of sealing, probe lead wire 10 passes through probe elongation line joint 8 and the probe elongation line is connected in bent pipe 9 after, tighten the union 4 of the electrical equipment bent pipe 9 that connects packing squeezed joint 3, just finished whole implementation process.
