Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
Unit loading type multipurpose pipe pump is by motor 1 among Fig. 1, motor cabinet 2, separable type coupling 3, pump cover 4, the pump housing 5, impeller 6, release lining 7, sealing plate 8, cartridge seal 9, guide bearing 10, sealing seat 11, pump shaft 12 compositions such as grade.
Cartridge seal 9 is the single mechanical end face seal of built-in type balance type, by sealing gland 9a, and axle sleeve 9b, positioning hole 9c, limiting board 9D, stop pin 9E, seal ring 9F, stationary ring 9G, revolving part 9H (forming), compositions such as seal ring 9W by parts such as rotating ring and flexible elements.
The endoporus of guide bearing 10 has the axle bush of a thin walled cylinder shape, axle bush bearing material manufacturing, and be fastened in the endoporus, make guide bearing become as a whole.
Sealing seat 11 is a hollow structure, and an annular space (cavity C) is arranged above, and mechanical seal 21 can be installed, and its ring-shaped cylinder face and end face are the locating face of sealing.
For dismounting easily, cartridge seal 9, guide bearing 10, sealing seat 11 all are arranged on the endoporus of pump cover 4, do radial location by the cylndrical surface in this hole, and its end face is done axially locating.Sealing seat 11 is used bolt, and nut is fixed on pump cover 4 upper ends, and the cylindrical flange below the sealing seat 11 is guide bearing 10, and cartridge seal 9 is pressed on the end face of pump cover 4 endoporus.Unclamp the nut on the sealing seat 11, can upwards split out sealing seat 11 along pump shaft 12 by cover parting bolt 24.At this moment, mechanical seal 21 is exposed on the pump shaft 12, and the set screw of release mechanism sealing 21 can be by axial removal mechanical seal 21.Similar with dismounting sealing seat 11, can split out guide bearing 10 and cartridge seal 9 easily by dismounting screw 22 and hole 9y.Rigid coupling 3 is the separable type structure, two half-couplings are fastening with screw 23, it fuses the axle of motor 1 with pump shaft 12, and guarantee mutual coaxality, one space 25 is arranged between the diaxon, the axial length in this space is greater than cartridge seal 9, and the axial height of guide bearing 10 and sealing seat 11 is so that above-mentioned part can split out outside the pump by space 25.
Motor cabinet 2 is parts of a hollow structure, dress motor 1 on it, it links to each other with pump cover 4 down, all use double-screw bolt each other, nut is fixed, and the both sides of motor cabinet 2 have bigger through hole 26, can take out coupling 3 by this hole, sealing seat 11 and guide bearing 10, cartridge seal 9, and mechanical seal 21.
There is an annular chamber 28 the motor cabinet upper end, joins with cooling plate 20 on it, uses 0 RunddichtringO (or pad) sealing between the two, and the outer wall of annular chamber 28 is provided with two screws 29.When carrying high temperature media, can link to each other with the cooling system of peripheral hardware by screw 29, make cooling water shuttling movement in annular chamber 28, with cooling motor seat 2 and motor 1.
Sealing plate 8 is installed between the pump housing 5 and the pump cover 4, by the cylndrical surface and the end face location of the pump housing.The lower flange of pump cover 4 is pressed on the sealing plate 9, the pump housing 5 and sealing plate 8, sealing plate 8 all seals with seal ring with pump cover, formed the water cooling chamber 30 of an annular thus between sealing plate 8 and the pump cover 4, it communicates with two external holes 31 on the pump cover 4, can be connected with the external refrigeration circulatory system through conduit (cooling tube), use water as cooling medium.
It is fixing that the thin nail of the release lining 7 usefulness junction of the edges of two sheets of papers is housed in the interior circular hole of sealing plate 8, and axial clearance 18 is arranged between the inner cylindrical surface of release lining 7 and the pump shaft, plays the throttling hypotensive effect, and this gap is more little, and it is big more to subtract the leakage resistance, and the leakage rate of liquid is also more little.
By shown in Figure 1, by release lining 7, sealing plate 8, cartridge seal 9 forms between the pump cover 4 with a cavity B, by Fig. 1, as seen Fig. 3, Fig. 4 have two to lead to outside radial hole 32 on the interior hole circle wall of pump cover 4, communicate the irrigating catheter that flushing hole 15 can external cartridge seal 9 respectively with two corresponding flushing holes 15 on the pump cover.According to the medium character that pump is carried, temperature, the difference of pressure can be selected different mechanical seal rinsing cooling schemes by the pump related standards.
By shown in Figure 1, a cavity A is arranged between cartridge seal 9 and guide bearing 10, because the seal action of cartridge seal 9, cavity A and cavity B are isolated, between guide bearing 10 and sealing seat 11, form with another cavity C, because have attachment hole 13 on the guide bearing 10, so cavity A communicates with cavity B.Have two circulation ports 14 on the sealing seat 11, according to the situation of pump fed sheet of a media, this two circulation port can be loaded onto conduit respectively and link to each other with the cooling unit of peripheral hardware, and mechanical seal 21 and guide bearing are cooled off with lubricated, and this cooling liquid is also cooled off pump shaft 12 simultaneously.
Under the normal temperature situation, can inject cutting oil through circulation port 14 mechanical seal 21 and guide bearing 10 are cooled off and lubricated.Because the axle bush of guide bearing 10 is in good lubricating status work, so the life-span is long, reliable operation.Because guide bearing 10 acts on reliably, can guarantee the high-axiality of 1 on pump shaft 12 and motor, thereby make pump work more steady, noise is littler, and seal operation is also more reliable, and the user cost of pump is also lower.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used cartridge seal morely, mechanical seal, sealing plate, the release lining, the possibility of using other term do not got rid of in terms such as annular chamber.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
