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 removable secondary seal structure of the utility model, including pump are schematically showed
Axis 1 and the secondary sealer 2 being set on pump shaft 1 and the two surround the secondary seal chamber 3 being arranged around pump shaft 1, secondary close
Seal apparatus 2 is removably attachable to the pump housing 6；Sealing mechanism 4 and electromagnetic driver 5, electromagnetic driver are equipped in secondary seal chamber 3
5 are located on one end of sealing mechanism 4 (i.e. the media end or atmosphere end of sealing device), and sealing mechanism 4 includes being set in pump shaft 1
On static components 42 and moving ring assembly 41, static components 42 be fixedly connected on the madial wall of secondary seal chamber 3, moving ring assembly 41
Actively be connected in pump shaft 1, the seal face 42a of static components and the seal face 41a of moving ring assembly be oppositely arranged and
Therebetween it is equipped with gap 43, corresponding electromagnetic driver 5 is also loop configuration, and electromagnetic driver 5 is attracting or repelling rotating ring
When component 41, the electromagnetic force that electromagnetic driver 5 applies moving ring assembly 41 is more uniform.When electromagnetic driver 5 not it is electric
When, moving ring assembly 41 and static components 42 are separated from each other, and are not rubbed therebetween, therefore do not form it in secondary seal
When, moving ring assembly 41 and static components 42 will not be worn, and be not necessarily to daily maintenance.When electromagnetic driver 5 must be electric, electromagnetism
Driver 5 attracts or repels moving ring assembly 41, forces moving ring assembly 41 to be moved towards static components 42 and is tightly attached to static components
42, occur to rub and formed secondary seal between static components 42 and moving ring assembly 41, the medium in the pump housing 6 is prevented further to ooze
Leakage, reduces the economic loss of user.Moreover, dismountable secondary sealer 2 can be mounted on arbitrary a no secondary seal work(
On the pump housing 6 of energy, user need to only purchase secondary sealer 2, need not replace the entire pump housing 6；When secondary sealer 2 damages
After failure, moreover it is possible to by its integral demounting, integral replacing, greatly reduce 6 maintenance time of the pump housing, the utilization rate of the pump housing 6 is further
It improves.
In the present embodiment, secondary sealer 2 is rotary structure, is circumferentially set on the end face of secondary sealer 2
There is a circle to connect through-hole 21, secondary sealer 2 is removably attachable to the pump housing 6 by bolt.Secondary sealer 2 includes shell
Body sidewall 22 and air side end cap 23, air side end cap 23 are removably attachable to housing sidewall 22, and static components 42, which are fixed, to be connected
It is connected to the madial wall of housing sidewall 22, static components 42 in secondary sealer 2, moving ring assembly are needed replacing as maintenance personal
41 or when electromagnetic driver 5, atmospheric side end cap 23 can be removed, inner body is directly replaced, without filling entire secondary seal
It sets 2 to remove, reduces the amount of labour of maintenance personal.Moving ring assembly 41 is located at the media end of static components 42, when sealing device shape
At secondary seal, i.e. moving ring assembly 41 is tightly attached to static components 42, Jie in the pump housing 6 under the guiding function of electromagnetic driver 5
Matter can generate moving ring assembly 41 certain pressure (such as hydraulic pressure), and the pressure that medium applies moving ring assembly 41 can force rotating ring group
Part 41 is tightly attached to static components 42；If moving ring assembly 41 to be located to the atmosphere end of static components 42, although being convenient for rotating ring in this way
The dismounting and change of component 41, but when being tightly attached to static components 42 under guiding function of the moving ring assembly 41 in electromagnetic driver 5,
Since the medium in the pump housing 6 produces moving ring assembly 41 certain pressure, electromagnetic driver 5 will also export the driving force of bigger
It offsets the pressure that medium generates moving ring assembly 41, moving ring assembly 41 is tightly attached in static components 42.Electromagnetic driver 5
It is located at the atmosphere end of sealing device, the i.e. atmosphere end of static components 42, the benefit being arranged in this way is when media leaks and sealing dress
It sets when foring secondary seal, moving ring assembly 41 and static components 42 come medium and the isolation of electromagnetic driver 5, at this time electromagnetism
Medium protective layer need not be installed outside driver 5 additional again, and the atmosphere end that electromagnetic driver 5 is located to sealing device is also convenient for electricity
The repair of magnetic driven device 5 is replaced.In addition, the lateral wall of pump shaft 1 is equipped with pin 11, corresponding, the madial wall of moving ring assembly 41
Be equipped with limiting slot, pin 11 is embedded in limiting slot, the cooperation of pin 11 and limiting slot enable moving ring assembly 41 steadily
Pump shaft 1 is followed to rotate.The first sealing ring 24, static components 42 and secondary are equipped between the madial wall and pump shaft 1 of moving ring assembly 41
The second sealing ring 25, the first sealing ring 24 and the second sealing ring 25 are equipped between the madial wall of seal chamber 3 for enhancing rotating ring group
Between the madial wall and pump shaft 1 of part 41 and the leakproofness between static components 42 and the madial wall of secondary seal chamber 3, prevent from being situated between
Matter further leaks.Certainly, which can also access tele-control system, believe specifically, secondary sealer 2 is equipped with control
Number input port 26, control signal input mouth 26 are electrically connected at electromagnetic driver 5, and monitoring personnel can be long-range in control room
Manipulate the running of electromagnetic driver 5.
In conclusion the removable secondary seal structure of the utility model, is removably equipped with secondary seal on the pump housing 6
Device 2, secondary sealer 2 are set in the secondary seal chamber 3 for surrounding on pump shaft 1 and with pump shaft 1 and being arranged around pump shaft 1 jointly,
The static components 42 being oppositely arranged and moving ring assembly 41, static components 42 and moving ring assembly 41 are equipped in secondary seal chamber 3 flat
When be separated from each other, do not rub, Maintenance free；When the pump housing 6 sealing of itself leaks, moving ring assembly 41 drives in electromagnetism
