Abstract
The present invention relates to an improved magnetic pump which is characterized in that components of sliding bearings for forming three pairs of friction pairs in a pump, a pump shaft, a moving ring, a fixed ring, a support ring, etc. are all made of corindon ceram materials. The corindon ceram has the advantages of high hardness, abrasion resistance and little abrasion loss to the friction pair, and thus, the service life of the magnetic pump is prolonged. In addition, the corindon ceram also has the advantages of high temperature resistance, low heat expansion coefficient, slow heat conduction and capability of bearing dry friction. Through experiments, the magnetic pump with the structure is overhauled after no-load running for 4 hours, and the components are unwounded. Thus, the limitation that the magnetic pump must operate with liquid and the no-load running of the pump is strictly prohibited is overcome. The improvement is a big progress of the magnetic pump technology.
Description
The present invention relates to a kind of improved magnetic drive pump.
Placing between the same pump shaft of impeller, pump cover and the separation sleeve of magnetic drive pump pump chamber has three pairs of friction pairs, and a sliding bearing that is mounted in the impeller endoporus forms movingly with pump shaft; Two rotating rings that are mounted in the impeller front-end face form the end face motive sealing with the ring of deciding on the pump cover; The 3rd, the end face of sliding bearing forms end-face friction with the supporting ring end face on the separation sleeve behind the impeller.The selection of material of these three pairs of friction pairs is one soft one to fight recklessly rightly for a long time, and pump shaft, fixed ring and supporting ring generally adopt corundum ceramic, and sliding bearing and rotating ring are then used teflon.The teflon thermal expansion coefficient is big, transmission of heat is fast, under the situation of dry friction, give birth to heat, expand in order to prevent friction pair, and component are out of shape, the regulation magnetic drive pump must be with the liquid operation in the use, by pump liquid friction pair is implemented pressure lubrication and cooling, but in the actual motion, the situation of magnetic drive pump aneroid idle running happens occasionally, and this just causes the damage of magnetic drive pump inevitably.
The purpose of this invention is to provide a kind of magnetic drive pump that allows no-load running.
The sliding bearing that solves key of the present invention and be impeller and the same pump shaft of rotating ring, fixed ring be the same with supporting ring all to adopt the corundum ceramic manufacturing.
Accompanying drawing is a structural drawing of the present invention, below in conjunction with accompanying drawing content of the present invention is described in further detail.
Magnetic drive pump is made up of motor (1), link press span (2), separation sleeve (3), pump cover (4), magnet steel cup (5), impeller (6) and pump shaft (7).Magnet steel cup (5) is installed on the motor shaft, places the magnet steel chamber between the same separation sleeve of link press span (2) (3), and magnet steel cup (5) is provided with outer steel (8).Impeller (6) and pump shaft (7) place the pump chamber between the same separation sleeve of pump cover (4) (3), be provided with interior magnet steel (9) in the impeller (6), impeller (6) by sliding bearing (10,11) same pump shafts (7) movingly the end bearing of And by pump shaft (7) on the supporting ring of being located at separation sleeve (3) (12), the other end of impeller (6) then by end face motive sealing supporting, be made up of rotating ring (13) on the impeller (6) and the ring of deciding on the pump cover (4) by this end face motive sealing.All all use high strength, corrosion-resistant material manufacturing with the part of medium contact in the pump chamber, wherein the material of pump cover (4), impeller (6) and separation sleeve (3) is engineering plastics, the material of sliding bearing (10,11), pump shaft (7), rotating ring (13), fixed ring (14) and supporting ring (12) is a corundum ceramic, and the corundum ceramic part surface should carry out mirror finish.
Corundum ceramic material hardness height, wear-resistant, high temperature resistant, thermal expansion coefficient is low, transmission of heat is slow, with three pairs of friction pairs of this material magnetic drive pump, wearing and tearing are slow, the working life of having improved magnetic drive pump, in addition, the magnetic drive pump of said structure is opened and inspect after no-load running in 4 hours test, part is excellent, thus the problem of forbidding no-load running that has solved that magnetic drive pump for many years exists always.Undoubtedly, this improvement is a much progress of magnetic drive pump technology.
Claims (1)
1, a kind of magnetic drive pump, one end of impeller is bearing on the supporting ring of being located at separation sleeve by pump shaft, the other end of impeller is by the end face motive sealing supporting that ring is formed of deciding on rotating ring on the impeller and the pump cover, sliding bearing on the impeller forms movingly with pump shaft, and the material of pump shaft, supporting ring and fixed ring is a corundum ceramic, the invention is characterized in: the material of sliding bearing (10 and 11) and rotating ring (13) also is corundum ceramic.
