Abstract
The invention discloses a novel magnetizing fluid seal device. The novel magnetizing fluid seal device comprises permanent magnets, annular magnet poles and a magnetic conduction shaft cover, wherein the magnetic conduction shaft cover is sleeved with a main shaft, the annular magnet poles are connected with the magnetic conduction shaft cover in a sleeved mode, magnetizing fluid is filled in the clearance spaces between the annular magnet poles and the magnetic conduction shaft cover, the annular magnet poles are multiple, a permanent magnet is arranged between two adjacent annular magnet poles, an added magnetizing fluid device is arranged on each annular magnet poles in a matched mode, and each added magnetizing fluid device is provided with the corresponding magnetizing fluid inside. The novel magnetizing fluid seal device is simple in structure, and easy to manufacture. Further, no complex parts are required and the requirements for the shaft surface quality and clearance processing are not high. The novel magnetizing fluid seal device can realize zero leakage as long as under the tolerant pressure differential range due to the fact that the seal is formed by a fluid, and therefore the seal for an extremely toxic substance, a combustible substance, an explosive substance, a radioactive substance and particularly a precious substance and a substance with high purity can be realized.
Description
Technical field
The present invention relates to the field of sealing technology of chemical reaction still, specifically, relate to a kind of New Magnetic Field Controlled fluid seal apparatus.
Background technique
In the industrial production such as petrochemical industry, a lot of courses of reaction is all in liquid phase or gas phase, and carry out under there is high-temperature and high-pressure conditions, all there is the sealing problem of a fluid in its connected system.If the sealability of equipment can not ensure and working medium leaks, cause the loss of material and the loss of energy, cause the pollution of environment, production can not normally run, and even jeopardizes the life safety of health.And be a urgent problem for the sealing of hypertoxic, inflammable, explosive material, existing seal arrangement can not accomplish self-healing performance, can not ensure production safety in course of reaction.
Summary of the invention
The present invention, in order to overcome the deficiency of above-mentioned technical problem, provides a kind of New Magnetic Field Controlled fluid seal apparatus, can be applicable to the sealing of severe toxicity, inflammable, explosive material completely.
The technological scheme solved the problems of the technologies described above is as follows:
A kind of New Magnetic Field Controlled fluid seal apparatus, comprise permanent magnet, annular magnetic pole and magnetic conduction axle sleeve, described magnetic conduction axle sleeve and main shaft are socketed, described annular magnetic pole is socketed in described magnetic conductive axis and puts, be filled with magnetic fluid between the space between described annular magnetic pole and magnetic conduction axle sleeve, described annular magnetic pole has several, is provided with permanent magnet in the middle of adjacent two annular magnetic poles, on each annular magnetic pole, supporting being provided with adds magnetohydrodynamic plant, and magnetic fluid is equipped with in the described magnetohydrodynamic plant inside that adds.
The inside of each annular magnetic pole is also provided with water cooling tank.
The inside of each annular magnetic pole is provided with two water cooling tanks, and is symmetrical arranged.
Sealing configuration of the present invention is simple, because be the sealing formed by liquid, as long as in the pressure differential range allowed, it can realize zero leakage, thus for the sealing of hypertoxic, inflammable, explosive, radioactive material, particularly precious material and high purity substance.Because the present invention is noncontact seal, then there is not solid friction, only have the liquid friction of magnetic fluid inside, therefore power consumpiton is low, and long service life is easy to safeguard.Depend primarily on the consumption of magnetic fluid sealing life, and magnetic fluid when not affecting equipment and running well, can add by adding magnetohydrodynamic plant, to make up the loss of magnetic fluid.Instantaneous overvoltage, when pressure falls after rise, magnet fluid sealing can heal automatically.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention;
In figure: 1 is permanent magnet, 2 is magnetic fluid, and 3 for adding magnetohydrodynamic plant, 4 be water cooling tank, 5 for annular magnetic pole, 6 is magnetic conduction axle sleeve.
Embodiment
A kind of New Magnetic Field Controlled fluid seal apparatus as shown in Figure 1, comprise permanent magnet 1, annular magnetic pole 5 and magnetic conduction axle sleeve 6, described magnetic conduction axle sleeve 6 is socketed with main shaft, described annular magnetic pole 5 is socketed on described magnetic conduction axle sleeve 6, magnetic fluid 2 is filled with between the space between described annular magnetic pole 5 and magnetic conduction axle sleeve 6, described annular magnetic pole 5 has several, permanent magnet 1 is provided with in the middle of adjacent two annular magnetic poles 5, on each annular magnetic pole 5, supporting being provided with adds magnetohydrodynamic plant 3, and magnetic fluid 2 is equipped with in described magnetohydrodynamic plant 3 inside that adds.The inside of each annular magnetic pole 5 is also provided with water cooling tank 4.The inside of each annular magnetic pole 5 is provided with two water cooling tanks 4, and is symmetrical arranged.
In magnet fluid sealing, because magnetic fluid can be lossy, arrange and add the supply that magnetohydrodynamic plant realizes magnetic fluid.Temperature rising due to magnetic fluid can affect the voltage endurance capability of sealing, should install bosh and lower the temperature.Sealing configuration of the present invention is simple, easy to manufacture.There is no complicated component, and to the surface quality of axle and gap processing request not high.Because be the sealing formed by liquid, as long as in the pressure differential range allowed, it can realize zero leakage, thus for the sealing of hypertoxic, inflammable, explosive, radioactive material, particularly precious material and high purity substance.Because the present invention is noncontact seal, then there is not solid friction, only have the liquid friction of magnetic fluid inside, therefore power consumpiton is low, and long service life is easy to safeguard.Depend primarily on the consumption of magnetic fluid sealing life, and magnetic fluid when not affecting equipment and running well, can add by adding magnetohydrodynamic plant, to make up the loss of magnetic fluid.Instantaneous overvoltage, when pressure falls after rise, magnet fluid sealing can heal automatically.
