Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
With reference to shown in Fig. 1 and Fig. 2, the secondary sealer for possessing leak detection of the present invention, bag are schematically showed
The secondary sealer 2 being set on pump shaft 1 is included, secondary sealer 2 includes rotating ring 3, stationary ring 4, rotating ring drive division 5, seepage
Sensor 6 and seepage controller 7, secondary sealer 2 and pump shaft 1 surround secondary seal chamber 8, in secondary seal chamber 8
The rotating ring 3 that can be slided along the axial direction of pump shaft 1 is actively arranged on pump shaft 1, leakage sensors 6 are provided with secondary seal chamber 8, are moved
Ring drive division 5 and stationary ring 4, the end face of stationary ring 4 and the end face of rotating ring 3 are oppositely arranged and are provided with gap therebetween, seepage control
Device 7 is electrically connected in leakage sensors 6 and rotating ring drive division 5.When leakage sensors 6 are not detected by media leaks, move
It is separated from each other between ring 3 and stationary ring 4 and is provided with gap therebetween, therefore, in the feelings that liquid pumping device (not indicating) runs well
Under condition, all without sealing is participated in, frictional dissipation will not also occurs in the two for rotating ring 3 and stationary ring 4.When leakage sensors 6 detect Jie
During matter seepage, leakage data caused by leakage sensors 6 is handled and sends two to rotating ring drive division 5 by seepage controller 7
Secondary sealing signal, rotating ring drive division 5 promote rotating ring 3 to be moved towards stationary ring 4, make the end face of rotating ring 3 tight according to secondary seal signal
Paste the end face of stationary ring 4.Now occur to rub between rotating ring 3 and stationary ring 4 and form secondary seal, prevent medium from further leaking.
In the case, the sealing of liquid pumping device in itself has been failed, but the rotating ring 3 and the two of the formation of stationary ring 4 by secondary sealer 2
Secondary sealing so that liquid pumping device is continued to run with, and is raced against time for the unplanned property shutdown of liquid pumping device, is greatly reduced and use
The economic loss at family.
In order to optimize the present apparatus, stationary ring 4 is located at one end of the atmospheric side of rotating ring 3, when rotating ring drive division 5 promotes rotating ring 3 tight
When being affixed on stationary ring 4, the pressure of medium simultaneously also can pushing tow rotating ring 3, rotating ring 3 is close on stationary ring 4, be further ensured that secondary close
The sealing effectiveness of envelope, prevents medium from leaking again.Rotating ring 3, stationary ring 4 and rotating ring drive division 5 are respectively positioned on the air of secondary seal chamber 8
Side one end, leakage sensors 6 are located at side medium one end of secondary seal chamber 8, first can be from secondary close when seepage occurs for medium
The side medium for sealing chamber 8 flows into secondary seal chamber 8, and leakage sensors 6 can detect leakage scenarios the very first time in the case,
Secondary sealer 2 can form secondary seal by rotating ring 3 and stationary ring 4 in time.
In the present embodiment, seepage controller 7 is installed on the lateral wall of secondary sealer 2 so that secondary seal fills
Putting 2 can be compact with holding structure on the basis of its function is met.Rotating ring drive division 5 is electromagnet, and rotating ring drive division 5 is located at
Wherein one end of stationary ring 4, rotating ring 3 are located at the other end of stationary ring 4.When rotating ring drive division 5 must be electric, the magnetic of rotating ring drive division 5 moves
Ring, rotating ring 3 is set to be moved along pump shaft towards stationary ring 4, the end face of stationary ring 4 is close in the end face of final rotating ring 3, completes rotating ring 3 and stationary ring 4
Secondary seal.Circumferential direction of the madial wall of secondary seal chamber 8 along secondary seal chamber 8 is provided with groove 81, and stationary ring 4 and rotating ring drive
Dynamic portion 5 is stacked, and in the embedded groove 81 of the fixing end of the two, and stationary ring 4 and rotating ring drive division 5 are installed in secondary close with this
Seal in chamber 8.
In addition, being additionally provided with bled signal output port 9 on secondary sealer 2, seepage controller 7 is electrically connected at seepage
Signal output port 9；Leakage data caused by leakage sensors 6 is handled and exported to bled signal by seepage controller 7
Port 9 sends seepage pre-warning signal.User can carry out remote monitoring liquid pumping device by bled signal output port 9 and whether there is
The situation of media leaks.
In summary, the secondary sealer for possessing leak detection of the invention, its leakage sensors detect that medium oozes
After leakage, rotating ring can be close to stationary ring under the promotion of rotating ring drive division, to carry out secondary seal operation, avoid in liquid pumping device in itself
Seal failure after need to carry out liquid pumping device unplanned property shutdown processing, liquid pumping device can be in the secondary of secondary sealer
Continued to run with sealing, substantially reduce the economic loss of user.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and replacement can also be made, these improve and replaced
Also it should be regarded as protection scope of the present invention.
