Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but be not limited to the scope of the present invention.
With reference to shown in Fig. 1 and Fig. 2, the active sealing structure for having leak detection of the present invention, packet are schematically showed
The secondary sealer being set on pump shaft 1 is included, secondary sealer and pump shaft 1 surround the secondary seal set around pump shaft 1
Chamber 3, the interior leak detection sensor 5 for being equipped with electromagnetic driver 4, being electrically connected at electromagnetic driver 4 of secondary seal chamber 3 are surround
The moving ring assembly 7 that ground is fixedly connected on the static components 6 of 3 madial wall of secondary seal chamber and is actively set on pump shaft 1,
In, moving ring assembly 7 can slide on the axial direction of 1 upper edge pump shaft 1 of pump shaft；First is equipped between static components 6 and pump shaft 1
Gap 8, when pump shaft 1 is rotated relative to secondary sealer, pump shaft 1 and static components 6 will not rub, static components it is close
The seal face 71 of sealing end face 61 and moving ring assembly is oppositely arranged and is equipped with Second gap 9 therebetween, is not oozed in the pump housing
When leakage, static components 6 and moving ring assembly 7 are separated from each other, and do not generate friction, in this way can be non-maintaining, are cut operating costs.
When media leaks occur for the pump housing, leak detection sensor 5 generates leakage data after detecting leakage and is sent to electromagnetic driver
4, electromagnetic driver 4 handles leakage data and is attracted or repel moving ring assembly 7, forces moving ring assembly 7 towards stationary ring group
Part 6 moves and is tightly attached to static components 6, and moving ring assembly 7 and static components 6 occur friction and form secondary seal at this time, prevents to be situated between
Matter continues to leak.Even if the sealing structure failure of the pump housing in itself leaks, secondary sealer is also allowed for as interim benefit
Measure is rescued, the unplanned property of the pump housing is avoided to shut down, causes user's economic loss.
In order to optimize the structure, moving ring assembly 7 is located at the media end of static components 6, when sealing device formed it is secondary close
Envelope, i.e. moving ring assembly 7 are tightly attached to static components 6 under the guiding function of electromagnetic driver 4, and the medium in the pump housing can be to rotating ring group
Part 7 generates certain pressure (such as hydraulic pressure), and the pressure that medium applies moving ring assembly 7 can force moving ring assembly 7 to be tightly attached to stationary ring
Component 6；If moving ring assembly 7 to be located to the atmosphere end of static components 6, although in this way convenient for the dismounting and change of moving ring assembly 7,
It is when being tightly attached to static components 6 under guiding function of the moving ring assembly 7 in electromagnetic driver 4, since the medium in the pump housing is to dynamic
Ring assemblies 7 produce certain pressure, and electromagnetic driver 4 will also export the driving force of bigger to offset medium to moving ring assembly 7
The pressure of generation, moving ring assembly 7 is tightly attached in static components 6.Electromagnetic driver 4 is located at the atmosphere end of static components 6, this
The benefit of sample setting is the moving ring assembly 7 and quiet when media leaks and moving ring assembly 7 and static components 6 form secondary seal
Ring assemblies 6 come medium and the isolation of electromagnetic driver 4, need not install medium protective layer outside electromagnetic driver 4 additional again at this time, and
And by electromagnetic driver 4 be located at static components 6 atmosphere end be also convenient for electromagnetic driver 4 repair replace.Leak detection senses
Device 5 is located at the media end of secondary seal chamber 3, so that 5 first time of leak detection sensor detects the sealing knot of the pump housing in itself
The medium that structure leaks out, so as to take secondary seal measure in time.In addition, the lateral wall of pump shaft 1 is equipped with pin 11, it is corresponding
, the madial wall of moving ring assembly 7 is equipped with limiting slot 72, and pin 11 is embedded in limiting slot 72, pin 11 and limiting slot 72
Cooperation enables moving ring assembly 7 that pump shaft 1 steadily is followed to rotate.The seal face 61 of static components is equipped with stationary seal ring 62,
The seal face 71 of moving ring assembly is equipped with rotary packing ring 73, and stationary seal ring 62 and rotary packing ring 73 are oppositely arranged and therebetween
Equipped with Second gap 9, stationary seal ring 62 and rotary packing ring 73 are preferably rubber material, possess more preferably sealing performance, Er Qiejing
Sealing ring 62 is removably attachable to the seal face 61 of static components, and rotary packing ring 73 is removably attachable to moving ring assembly
Seal face 71, in order to detachable maintaining.Secondary sealer is equipped with control signal input mouth 21, control signal input
Mouth 21 is electrically connected in electromagnetic driver 4 and leak detection sensor 5, and monitoring personnel remote monitoring can ooze in control room
The situation of leakage and the running of remote control electromagnetic driver 4.
In conclusion leakage inspection is equipped in the secondary seal chamber 3 of the active sealing structure for having leak detection of the present invention
Sensor 5 is surveyed, leak detection sensor 5 can detect the sealing structure leakage of the pump housing in itself in time；Its static components 6 and pump
First gap 8 is equipped between axis 1, avoids static components 6 and pump shaft 1 that frictional dissipation occurs, is set between moving ring assembly 7 and static components 6
There is Second gap 9, moving ring assembly 7 and static components 6 do not rub when the pump housing does not leak, non-maintaining；When the pump housing is sent out
Raw media leaks, moving ring assembly 7 are tightly attached to static components 6 and are rubbed under the driving of electromagnetic driver 4, are formed secondary close
Envelope, prevents medium from further leaking, and the unplanned property shutdown for the pump housing is raced against time.
The 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, several improvement and replacement can also be made, these improve and replace
Also it should be regarded as protection scope of the present invention.
