Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
In conjunction with shown in Fig. 1 and Fig. 2, the realizing active sealing knot for having leak detection of the utility model is schematically showed
Structure, including the secondary sealer that is set on pump shaft 1, secondary sealer and pump shaft 1 surround be arranged around pump shaft 1 it is secondary
Seal 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,
The moving ring assembly for being circumferentially fixedly connected on the static components 6 of 3 madial wall of secondary seal chamber and being actively set on pump shaft 1
7, wherein moving ring assembly 7 can slide on the axial direction of 1 upper edge pump shaft 1 of pump shaft；It is equipped between static components 6 and pump shaft 1
First gap 8, when pump shaft 1 is rotated relative to secondary sealer, pump shaft 1 and static components 6 will not rub, static components
Seal face 61 and moving ring assembly seal face 71 be oppositely arranged and therebetween be equipped with Second gap 9, do not sent out in the pump housing
When raw 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, reduce operation
Cost.When media leaks occur for the pump housing, leak detection sensor 5 generates leakage data after detecting leakage and is sent to electromagnetism drive
Dynamic device 4, electromagnetic driver 4 handle leakage data and are attracted or repelled moving ring assembly 7, force moving ring assembly 7 towards quiet
Ring assemblies 6 move and are tightly attached to static components 6, and moving ring assembly 7 and static components 6 occur friction and form secondary seal at this time, hinder
Only medium continues to leak.Even if the sealing structure failure of the pump housing itself leaks, also allowing for secondary sealer becomes interim
Remedial measure, avoid the unplanned property of the pump housing from shutting down, cause 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 is 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 being convenient for the dismounting and change of moving ring assembly 7 in this way,
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
