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 axial-flow pump of the electromagnetic type secondury sealing of the present invention is schematically showed, including hang down
The pump shaft 1 directly set in horizontal plane and the secondary sealer 2 being set on pump shaft 1, secondary sealer 2 and pump shaft 1 enclose
The secondary seal chamber 3 that cyclization is set around pump shaft 1, secondary seal chamber 3 is interior to be equipped with electromagnetic driver 4, is circumferentially fixedly connected on two
The static components 5 of secondary 3 madial wall of annular seal space and the moving ring assembly 6 being actively set on pump shaft 1, wherein, 6 energy of moving ring assembly
It is enough to be slided on pump shaft 1 along the axial direction of pump shaft 1；The seal face 51 of static components and the seal face 61 of moving ring assembly
It is oppositely arranged and is equipped with gap 7 therebetween, moving ring assembly 6 is located at the lower section of 1 axial direction of pump shaft of static components 5；Work as electricity
Magnetic driven device 4 not it is electric, moving ring assembly 6 by gravity away from static components 5, at this time between moving ring assembly 6 and static components 5
Friction is not produced, is not worn, and when electromagnetic driver 4 must be electric, electromagnetic driver 4 attracts or repel moving ring assembly 6, forces
Moving ring assembly 6 moves towards static components 5 and is close to static components 5, and friction is produced between moving ring assembly 6 and static components 5
And secondary seal is formed, prevent medium from further leaking.Since moving ring assembly 6 has away from static components under gravity
5 movement tendency, therefore the elastic components such as spring need not be set between moving ring assembly 6 and static components 5, to ensure moving ring assembly 6
It can also keep being separated from each other when the former sealing structure of the pump housing 8 does not leak with static components 5.Spring is avoided when elastic component when long
Between damage failure after use, moving ring assembly 6 and static components 5 cannot get the bouncing off effect of elastic component and occur it is insignificant mutually
Friction.
The pump housing 8 of this axial-flow pump is equipped with the former moving sealing ring 83 of water inlet 81 and water outlet 82, water inlet 81 and the pump housing 8
Lateral wall be oppositely arranged, the medium introduced from water inlet 81 is used for cooling and lubricating original moving sealing ring 83, to ensure that former sealing is moved
The sealing performance of ring 83 and former stationary seal ring 84.Further, the pump housing 8 be equipped with the oral siphon 85 plugged into water inlet 81 and
The outlet pipe 86 plugged into water outlet 82, outlet pipe 86 are communicated in oral siphon 85 by a liquid pumping device (not shown), this causes
For cooling and lubricating original moving sealing ring 83 and the medium reusable edible of stationary ring, it is unlikely to waste of resource.
In order to optimize the structure of this axial-flow pump, electromagnetic driver 4 is located at static components 5 and the atmosphere end of moving ring assembly 6, this
The benefit that sample is set is the moving ring assembly 6 and quiet when media leaks and static components 5 and moving ring assembly 6 form secondary seal
Ring assemblies 5 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 the atmosphere end that electromagnetic driver 4 is located to static components 5 and moving ring assembly 6 is also convenient for the maintenance of electromagnetic driver 4 and replaces.This
Outside, the lateral wall of pump shaft 1 is equipped with pin 11, corresponding, and the madial wall of moving ring assembly 6 is equipped with limiting slot 63, and pin 11 is embedding
In limiting slot 63, the cooperation of pin 11 and limiting slot 63 enables moving ring assembly 6 steadily to follow pump shaft 1 to rotate.Stationary ring
The seal face 51 of component is equipped with stationary seal ring 52, and the seal face 61 of moving ring assembly is equipped with rotary packing ring 62, static seal
Ring 52 and rotary packing ring 62 are oppositely arranged and are equipped with gap 7 therebetween, and stationary seal ring 52 and rotary packing ring 62 are preferably rubber
Material, possesses more preferably sealing performance, and stationary seal ring 52 is removably attachable to the seal face 51 of static components, moves close
Seal ring 62 is removably attachable to the seal face 61 of moving ring assembly, in order to detachable maintaining.
In conclusion the pump shaft 1 of the axial-flow pump of the electromagnetic type secondury sealing of the present invention is set perpendicular to horizontal plane, rotating ring group
Part 6 is actively set on pump shaft 1, wherein, moving ring assembly 6 can slide on pump shaft 1 along the axial direction of pump shaft 1, quiet
The seal face 51 of ring assemblies and the seal face 61 of moving ring assembly are oppositely arranged and are equipped with gap 7 therebetween, in the pump housing 8
In the case of the sealing structure ne-leakage of body, moving ring assembly 6 is due to gravity away from static components 5, it is ensured that moving ring assembly 6 and quiet
Insignificant abrasion will not occur under normal conditions for ring assemblies 5.
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, some improvement and replacement can also be made, these improve and replace
Also it should be regarded as protection scope of the present invention.
