Rise, be fixed on bottom plate bottom, pump is arranged on container entirely through bottom plate；The impeller is mounted in suction inlet, in impeller and pump
There is sealing ring between lid；The lower axle is connected with upper axle by spindle key and spindle set, and lower axle is equipped with the body of sliding bearing；The cunning
Dynamic bearing body includes arc lubrication groove and guide bearing, and the arc lubrication groove is helical form, through the inner surface of whole guide bearing,
High-tension lubrication liquid can effectively enter the whole inner surface of guide bearing, make lubricant effect more preferable, extend the use of guide bearing
Life-span.
The beneficial effects of the invention are as follows：Present invention optimizes shaft design, increases the bearing pointdisposal of axle, diameters of axle ratio was originally
There is increase, critical speed of shaft is far above working speed, it is ensured that pump can operate steadily under very harsh operating mode；Improve
The material of guide bearing, using the match dragon material of import, it substantially prolongs the service life of guide bearing；Increase the lubrication of guide bearing
Groove, arc lubrication groove is helical form, and through the inner surface of whole guide bearing, high-tension lubrication liquid can effectively enter guide shaft
The whole inner surface held, makes lubricant effect more preferable；More than pump housing outlet flange bore 80mm, using double-volute structure, balance footpath
Xiang Li, reduce the vibration of pump；Spindle structure is improved, axle connection is safe and reliable, it is ensured that pump can be transported under very harsh operating mode
Row is steady.
Brief description of the drawings
Fig. 1 is the structure chart of one embodiment of the present of invention；
Fig. 2 is the enlarged drawing of the local I of one embodiment of the present of invention.
Embodiment
The present invention is further described for explanation and embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, vertical submerged pump with long shaft of the invention, including the pump housing 1, pump cover 4, impeller 2, sealing ring 3, lower axle
5th, upper axle 10, support tube 6, the body of sliding bearing 7, bearing bracket stand 12, bottom plate 11, joint member 14, drain pipe 16, motor 15；Pump
Suction inlet along axis direction, discharge opening and diameter parallel；Motor 15 on motor cabinet, and passes through shaft coupling with bolt tightening
Part 14 and pump direct drive, bearing bracket stand are mounted in the top of bottom plate 11, the joint member 14 are connected by bearing 13；The pump housing 1,
Pump cover 4, lower axle 5, support tube 6, upper axle 10, drain pipe 16, pipe flange are formed together with bolt-connection, are fixed under bottom plate 11
Portion, pump are arranged on container entirely through bottom plate 11；The impeller 2 is mounted in suction inlet, has between impeller 2 and pump cover 4 close
Seal ring 3；The lower axle 5 crosses spindle key 8 with upper axle logical 10 and spindle set 9 is connected, and lower axle is equipped with the body of sliding bearing 7；The slip
Bearing body 7 includes arc lubrication groove 17 and guide bearing 18, and the arc lubrication groove 17 is helical form, through whole guide bearing 18
Inner surface, high-tension lubrication liquid can effectively enter the whole inner surface of guide bearing, make lubricant effect more preferable, extend guide bearing
18 service life.The steering of pump is to be rotated clockwise in terms of drive end.
The end face of the upper axle 5 and lower axle 10 processes screw thread, is linked up two axles with a high-strength bolt 19,
Outside adds a spindle set 9 again, limits the mutual rotation between two axles, allows axle connection securely and reliably to ensure pump very
Operated steadily under harsh operating mode.
The motor is vertical machine, and the joint member is flexible coupling, and the vertical submerged pump with long shaft touches liquid
Part uses corrosion resistant austenitic stainless steel.
Axial force and radial load (including caused water pressure, impeller and the rotor in pump operating of the submerged pump of the present invention
Weight etc.), born by guide bearing in institute's dress angular contact ball bearing in bearing box and sliding bearing body.To ensure pump safety
Run well.Bearing lubricates it with butter, and guide bearing is by the hydrodynamic lubrication that is conveyed.Therefore, liquid level necessarily be greater than leaf during work
Take turns center line.
Present invention optimizes shaft design, increase the bearing pointdisposal of axle, diameters of axle ratio also has increase, makes critical turn of axle originally
Speed is far above working speed, it is ensured that pump can operate steadily under very harsh operating mode；The material of guide bearing is improved, using entering
The match dragon material of mouth, substantially prolongs the service life of guide bearing；Increase the lubrication groove of guide bearing, arc lubrication groove is spiral
Shape, through the inner surface of whole guide bearing, high-tension lubrication liquid can effectively enter the whole inner surface of guide bearing, make lubrication
Effect is more preferable；More than pump housing outlet flange bore 80mm, using double-volute structure, radial load is balanced, reduces the vibration of pump；Improve
Spindle structure, the end face of axle and lower axle processes screw thread on described, is joined two axles with a high-strength bolt (spindle key)
Pick up and, outside adds a spindle set again, limits the mutual rotation between two axles, makes axle connection securely and reliably to ensure that pump can be with
