The method and device provided by the invention has the beneficial effects that the service life of the magnetic pump is greatly prolonged and exceeds of the common pump, thereby achieving the purposes of reducing the cost and improving the work efficiency.
Description
Technical field
The present invention relates to a kind of encapsulating method and device thereof of magnetic drive pump.
Background technique
Magnetic drive pump is unique leak free advanced safety pump equipment, and pump head is generally arranged, band magnetic impeller, and axle sleeve (magnet ring center), the pump housing, axle, magnetic force outer shroud and motor are formed.Because the Security of magnetic drive pump is so all be applied to high temperature, the conveying of high-risk material, these materials have very high harmfulness, flowability, danger, such as: severe corrosive, radiativity, toxicity, consequence if take place to leak with unimaginable in high temperature etc., magnetic drive pump is in order to guarantee these high temperature, and zero of high-risk material is revealed.Many technology commonly used, design, selection have been subjected to considerable restraint, and traditional magnetic drive pump is because band magnetic impeller, axle, and axle sleeve directly is immersed in the medium and works.So the most frequently used, the most effective plain shaft has born environmental constraint, the tradition magnetic drive pump has been used bearing instead axle sleeve and directly rotary mode design of axle because of technical limitations, and because the severe corrosive of medium, axle, axle sleeve selection also have been subjected to considerable restraint, the magnetic drive pump of conventional art is under numerous technical limitations, fail effectively to solve the technical problem that occurs in using, many methods that are compelled against one's will have been adopted, institute is so that traditional magnetic drive pump is very short working life, the selection difficulty, the maintenance cost height, shortcomings such as inefficiency.
Summary of the invention
For overcoming the defective of prior art, the technical problem to be solved in the present invention has provided a kind of encapsulating method and device of magnetic drive pump.
To achieve these goals, the technical solution used in the present invention is: a kind of encapsulating method of magnetic drive pump, pump is by the pump housing, the pump head of outside, the inner magnetic impeller and the bearing of bearing support and bearing support inside constitute, magnetic impeller middle spindle hole is airtight, form and have only the airtight magnet ring cavity of the downward remaining part of magnet ring mouth; The magnetic impeller magnet ring magnet ring of packing into is indoor, and magnetic impeller magnet ring inwall has just formed a space with bottom, magnet ring chamber media isolated.
A kind of seal arrangement of magnetic drive pump comprises the pump housing, pump head and magnetic impeller, and magnetic impeller middle spindle hole is airtight, forms to have only the airtight magnet ring cavity of the downward remaining part of magnet ring mouth; The annular shaft bearing is set up at center, pump housing magnet ring chamber makes it form impeller magnet ring groove and the annular shaft bearing opening two airtight cavitys of remaining part that make progress in the same way; Magnetic impeller and airtight butt joint of axle, axle is fixed in the bearing support at center, pump housing magnet ring chamber together by bearing, and magnetic impeller magnet ring is positioned at pump housing magnet ring groove simultaneously, has just formed the annular gas separate cavities between magnetic impeller magnet ring inwall and the bearing support outer wall.
Described bearing support is provided with thermal-protective coating.
Described bearing support is provided with lubricating cavity.
The invention has the beneficial effects as follows: with bearing and axle and media isolated, for magnetic drive pump at severe corrosive, reflectivity, toxicity, can use the scope of bearing and the selection of expansion axle to create rigid condition in the media such as high temperature, thereby prolonged the working life of magnetic drive pump greatly, surmount the life-span of conventional pump, reduce cost the purpose of increasing work efficiency thereby reach.

Embodiment
A kind of encapsulating method of magnetic drive pump, pump are by the pump housing, the pump head of outside, and the inner magnetic impeller and the bearing of bearing support and bearing support inside constitute, and magnetic impeller middle spindle hole is airtight, form and have only the airtight magnet ring cavity of the downward remaining part of magnet ring mouth; The magnetic impeller magnet ring magnet ring of packing into is indoor, and magnetic impeller magnet ring inwall has just formed a space with bottom, magnet ring chamber media isolated.
A kind of seal arrangement of magnetic drive pump comprises the pump housing 3, pump head 1 and magnetic impeller 2, and magnetic impeller 2 central shaft holes are airtight, forms to have only the airtight magnet ring cavity 6 of the downward remaining part of magnet ring mouth; The annular shaft bearing is set up at center, pump housing magnet ring chamber makes it form impeller magnet ring groove (chamber) 10 and the annular shaft bearing opening two airtight cavitys of remaining part that make progress in the same way; Magnetic impeller and airtight butt joint of axle, axle 4 is fixed in the bearing support at center, pump housing magnet ring chamber together by bearing 5, magnetic impeller magnet ring 8 is positioned at pump housing magnet ring groove (chamber) 10 simultaneously, has just formed the annular gas separate cavities between magnetic impeller magnet ring inwall 7 and the bearing support outer wall 9.Also be provided with thermal-protective coating on the described bearing support.Also be provided with lubricating cavity on the described bearing support.
According to an aspect of of the present present invention, provide the encapsulating method that is used for a kind of magnetic drive pump: magnetic impeller middle spindle hole is airtight, form and have only the airtight magnet ring cavity of the downward remaining part of magnet ring mouth; The magnetic impeller magnet ring magnet ring of packing into is indoor, and magnetic impeller magnet ring inwall has just formed a space with bottom, magnet ring chamber media isolated.
The axle sleeve at traditional magnetic impeller magnet ring center is removed, added large space, the axis hole at airtight impeller center allows it become and has only magnet ring mouth (or making progress) downwards, the magnet ring inner chamber body that remaining part is airtight; The annular shaft bearing is set up at center, pump housing magnet ring chamber make it form impeller magnet ring groove and annular shaft bearing, in the same way opening (or downwards) two airtight cavitys of remaining part upwards; The magnetic impeller is carried out airtight the butt joint with axle, axle is fixed in the bearing support at center, pump housing magnet ring chamber together by bearing, magnetic impeller magnet ring enters in the pump housing magnet ring groove simultaneously, has just formed the annular gas separate cavities between magnetic impeller magnet ring (pump housing magnet ring groove) inwall and bearing support (the magnetic impeller magnet ring) outer wall.
Adopt method of the present invention and device, owing in the separate cavities air is arranged, and separate cavities Open Side Down with regard to one, again according to the flow characteristic of liquid, liquid level goes up, and the air in the separate cavities just can't flow, and runs off, can't enter separate cavities so be transferred medium, with bearing and the axle and media isolated, for magnetic drive pump at severe corrosive, reflectivity, toxicity, can use the method for bearing and the selection of amplification axle to create rigid condition in the media such as high temperature, thereby prolonged the working life of magnetic drive pump greatly, surmount the life-span of conventional pump, reduce cost the purpose of increasing work efficiency thereby reach.
