Background technique
Now commercially to pipeline rotating shaft attended operation trouble, if sealing effect misoperation, do not reach desirable sealing effect.The external requirement condition of device for sealing magnetic fluid in seal for pipe joints process is high, and installation process requires intricate operation.Magneticfluid Seal Technique develops on the basis of magnetic fluid, and when magnetic fluid injects the gap in magnetic field, it can be full of whole gap, is formed a kind of " the O RunddichtringO of liquid ".The function of device for sealing magnetic fluid is that rotary motion is delivered in seal container, is usually used in vacuum seal; By " zero leakage " motive sealing advanced technology that countries in the world are extensively generally acknowledged.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcoming existing equipment existence, provides a kind of rotating shaft tubular type piecing devices of magnet fluid sealing, just can play seal action by the Flange joint at its two ends to the pipeline of equipment, and the sealing effect of rotating shaft pipeline just very well.
In order to arrive above-mentioned purpose, the present invention is realized by following technical proposals: a kind of rotating shaft tubular type piecing devices of magnet fluid sealing are made up of device for sealing magnetic fluid, rotation tubular axis, fixed tubular axle.
Described device for sealing magnetic fluid is by magnetic conductance seat, bearing, magnetic pole, permanent magnet, magnetic conductive axis, magnetic fluid do not form, under the effect of uniform steady magnetic field, make magnetic fluid riddle in the space of setting, set up multistage " O RunddichtringO ", thus reach the effect of sealing; Every grade of seal ring generally can bear and be greater than 0.15 ~ 0.2 atmospheric pressure reduction.Total pressure-bearing is pressure reduction sums at different levels, is generally designed to 2.5 barometric pressure, and totally the withstand voltage progression with liquid round section joint ring increases and increases.
Described device for sealing magnetic fluid is arranged on and rotates between tubular axis and fixed tubular axle, and device for sealing magnetic fluid plays the space behavior between seal rotary tubular axis and fixed tubular axle.
Described device for sealing magnetic fluid is fixed in the convex groove of rotation tubular axis.
1, the convex groove rotating tubular axis is used for fixing the position of device for sealing magnetic fluid on rotation tubular axis and does not move.
2, the rotation outside of tubular axis and the inner face of device for sealing magnetic fluid are fixed as a whole.
3, rotating between the outside of tubular axis and the inner face of device for sealing magnetic fluid is gapless, sealed air-tight.
4, the pipe external diameter size rotating tubular axis is the same with the internal diameter size of device for sealing magnetic fluid.
Described fixed tubular axle is fixed on the outside of device for sealing magnetic fluid.
1, the inner face of fixed tubular axle and the outside of device for sealing magnetic fluid are fixed as a whole.
2, be gapless, sealed air-tight between the inner face of fixed tubular axle and the outside of device for sealing magnetic fluid.
3, the bore size of fixed tubular axle is the same with the external diameter size of device for sealing magnetic fluid.
Described rotation tubular axis, one end of fixed tubular axle have flange.
1, the flange rotated on the inlet end of tubular axis is used for the pipeline of the rotation on connection device.The pipeline rotated refers to the pipeline of the rotary motion on equipment, and the pipeline of this kind of rotation is for heat supply during cooperating equipment motion, exhaust.
On the exit end of 2, fixed tubular axle the fixing tube that is used on connection device of flange.Fixing pipeline refers to the fixed pipeline on equipment, and this kind of fixing pipeline is used for the heat supply fixed of equipment, fixing exhaust.
Described fixed tubular axle is the same with the mark caliber of domestic different pipe through size with the pipe rotating tubular axis, is convenient to the rotating shaft tubular type piecing devices directly installing and using magnet fluid sealing like this.
The present invention has following beneficial effect compared with existing seal arrangement joint: a kind of rotating shaft tubular type piecing devices of magnet fluid sealing, easy to use, on the rotating pipe that the flange rotating tubular axis one end is used on connection device, on the fixing tube that the flange of fixed tubular axle one end is used on connection device, just can play the effect of the pipeline of seal rotary, save labor, good sealing effect, maintenance also facilitates.
