Abstract
The present invention relates to an isolation sleeve assembled in a magnetic pump, and a production technology of the isolation sleeve, which solves the problems of large energy loss, poor temperature resistance, great compressive deformation, low accuracy, short service life, unreliable seal and complicated production processing. The present invention is characterized in that a material of epoxide structure resin is adopted as a basal body, and high-tech fiber and textile fabric of the high-tech fiber, such as S4 high-strength glass fiber or aramid fiber, etc. are used as reinforcing agents. The isolation sleeve has a thin side wall and the thick bottom end. The production technology comprises the following steps: firstly, a steel core mold is used for molding the reinforcing agents by continuous wet winding; then at a temperature of 180 DEG C, a steel mold is used for molding, solidifying and molding the wound and molded product. The present invention can effectively reduce energy loss, reliably seal mediums in a pump body and prevent external leakage.
Description
The invention belongs to the part device of the magnetic drive pump of contactless transmission, be specifically related to the separation sleeve and the production technology thereof of magnetic drive pump.
Magnetic drive pump has an outside magnet rotor by the motoring rotation, and an internal magnetic rotor is arranged in it, drives the internal magnetic rotor rotation by the magnetic induction band, drives the pump impeller that is connected with the internal magnetic rotor mechanical then and rotates, and magnetic drive pump is normally moved to be changeed.A separation sleeve is generally arranged between the magnet rotor of medial and lateral, and it is to prevent the critical component of the interior medium of the magnetic force contactless transmission pump housing to external leakage.
The magnetic drive pump application is increasingly extensive, and increasing magnetic drive pump is applied to diminish material (for example toxicant, unpleasant material, carcinogen etc.), the dangerous substance (for example corrosive material, explosive substance, combustible material etc.) of health or ecotope.Along with the reinforcement gradually of environmental protection consciousness, the leakage rate that reduces harmful matter in the pump housing become cause close important.People's an urgent demand further develops high-quality sealing technique, and what stand in the breach is that requirement designs and manufactures high-quality separation sleeve.
But all there are many serious problems in the separation sleeve that adopts at present:
1. the separation sleeve that adopts usually at present by the stainless steel manufacturing, though corrosion-resistant, advantages such as the life-span long, easy processing are arranged, and its deadly defect is to produce the magnetic eddy current when the magnetic line of force passes separation sleeve, makes energy loss bigger, and convert heat energy to and be collected at the separation sleeve surface, elevate the temperature.The magnetic drive pump rotating speed is very high, and that magnetic eddy current characteristics are rotating speeds is big more, and the magnetic eddy current is serious more, makes energy loss big more, and temperature rise is high more, can cause the demagnetization of inner and outer rotors permanent magnet magnetic cylinder when serious; Even when carrying inflammable, explosive medium, produce hidden danger.
2. the separation sleeve of making by pottery, though can not produce the magnetic vortex phenomenon, but ceramic material fragility is big, for durable in use, must increase the wall thickness of goods, make its structure heaviness, particularly because wall thickness makes outside magnet rotor and internal magnetic gap between rotor excessive, magnetic force loss is still very big, and the life-span is not long, dangerous.
3. the someone imagines with plastics and makes separation sleeve, though can not produce the magnetic vortex phenomenon yet, but plastics are thermoplastic material, even the liquid crystal polyester of high polymer, also there is the not characteristic of heatproof, the hurried deterioration of its performance in the time of more than 80 ℃ is difficult to the pressure of bearing pump in-vivo medium, the easy creep of material, easily aging be its deadly defect.
In sum, various separation sleeves in the prior art all can not satisfy the requirement of the high sealing technology of magnetic drive pump.People require the separation sleeve that a kind of energy loss is little, distortion is little, the life-span long, safe and reliable magnetic drive pump is used is provided always, determine but be situated between always with failing.
Task of the present invention is the difficult problem at prior art, designs the separation sleeve that a kind of magnetic drive pump is used, and reaches that the magnetic force energy loss is little, temperature tolerance good, it is little to be out of shape under pressure, the life-span is long, sealing is reliable and production and processing purpose easily.
The technical solution of the present invention centre point is surrounded:
1. the employing of the material of separation sleeve is a matrix with the epoxy construction resin; With S
4High-tech such as high-strength glass fibre or aramid fiber fiber and fabric thereof are strengthening agent.
2. the separation sleeve production technology mainly contains two operations;
(1) it is Wrapping formed to carry out continuous wet method with above-mentioned strengthening agent on the steel core;
(2) under 180 ℃ of high temperature conditions, with punching block above Wrapping formed semi-finished product are carried out molded curing and be shaped to needed separation sleeve.
3. separation sleeve is a hollow bottomed cylindrical shape body.Consider that stressed principal axis of strain is to more than radially big, for fully improving stock utilization, it is identical that the present invention is different from each part wall thickness of stainless steel separation sleeve, and adopt the even structure of wall unevenness, axially two ends are thicker is 3.5 to 4.5mm, and to get thickness be 2 to 3mm and radial wall is thin; Axially all adopt circular arc to be connected with jointing place radially; It is circular-arc that the bottom inside and outside wall also is.
The present invention has outstanding advantage and remarkable progress:
1. energy-saving effect is remarkable
Because adopt tec fiber strengthening agent and polymer matrix composites to make moulding, the magnetic line of force does not pass can produce the magnetic vortex phenomenon; And sidewall is thin, can make the gap of medial and lateral magnet rotor little near the thickness of Stainless Steel Products.Thereby magnetic force loss can be reduced as far as possible, and compare with conventional separation sleeve, average energy-conservation more than 10%.
2. heatproof, withstand voltage properties are good
These goods can be worked under temperature 〉=80 ℃, pressure 〉=2MPa condition safely and reliably, and the life-span is long, and the precision height can guarantee abundant sealing.
3. Security increases substantially
Cause separation sleeve surface heat accumulation, temperature to raise owing to avoid the magnetic eddy current to produce, guarantee Security inflammable, explosive medium transport; And prolong the magnetic cylinder permanent magnet life-span.
4. low production cost is easy to utilize
Separation sleeve of the present invention is suitable for producing in enormous quantities owing to adopt core to twine and the hot moulding solidifying, can reduce production costs greatly.
