Description
Technical field
The present invention relates to adjustable guide bearing mechanism more particularly to the adjustable guide bearing machines of large-sized vertical shaft open type water pump
Structure.
Background technique
Large-sized vertical shaft open type water pump generallys use radial support of the sliding bearing as rotor, generally uses twice guide shaft
It holds, is mounted on top cover top together, another road is mounted on lower part in hub in the diffuser of impeller.
In the prior art, the installation method that upper and lower guide bearing uses are as follows: top guide bearing building-site is adjusted in guide bearing
Hole is positioned with installation fastening bolt behind the concentric and gap of pump shaft and with positioning pin, lower guide bearing and diffuser is beaten using seam allowance,
Bolt fastening.
Because of the design feature that large-sized vertical shaft open type water pump has its special, diffuser need to couple with blade wheel chamber in clipping room
Good latter hangs in pump hole, and installation personnel can not descend fine tuning blade wheel chamber in pump hole to adjust relative to the radial position of diffuser
The clearance evenness degree of completeblade and blade wheel chamber, only by adjusting the radial position of rotor or integrated regulation diffuser and impeller
Room radial position adjusts the clearance evenness degree of blade and blade wheel chamber, and after adjustment gap can occur for rotor and lower guide bearing inner hole not
Uniform situation, building-site can not generally solve the problems, such as this.It needs to agree to by management and owner, lower guide bearing is returned factory will
Seam allowance size Che little Hou is sent to building site again, and lower guide bearing and diffuser are coupled after adjusting and is positioned with flange is stamped with diffuser
Pin, lower flange do not limit but radially, influence guide bearing to the guiding role of pump shaft.And such way heavy workload, it needs to return
Repair in shop is multiple, affects building-site installation；Raw water pump design size has been changed simultaneously, the construction time has been delayed, to product
Quality impact, or even can not by check and accept, and influence the duration.Therefore a kind of easy to adjust, building-site construction is needed
Measure small adjustable guide bearing mechanism.
Summary of the invention
Goal of the invention: for overcome the deficiencies in the prior art, the present invention provides a kind of large-sized vertical shaft open type water pump
Adjustable guide bearing mechanism, to realize building-site convenient working.
Technical solution: the adjustable guide bearing mechanism of the present invention includes lower guide bearing and locating ring, positioning bolt, locking screw
Female and positioning pin；The lower flange of lower guide bearing is locked by the way that positioning bolt and locking nut and locating ring circumferencial direction are fixed, under
The upper flange of guide bearing is fixed in diffuser on hub upper flange, and with positioning finger setting.
Locating ring is fixed in diffuser on hub lower flange by the fixed seam allowance of locating ring and locating ring fastening bolt.
The upper flange of lower guide bearing is bolted in diffuser on hub upper flange, and with positioning finger setting.
Working principle: for the present invention in water pump installation process, lower guide bearing is good laggard with one heart in water pump rotor mounting and adjusting
Row installation and adjustment, adjust lower guide bearing and pump shaft it is concentric after, with locating ring, positioning bolt, locking nut and positioning pin
Positioning and stop are carried out to lower guide bearing.
The utility model has the advantages that guide bearing mechanism in the prior art, to guarantee to lead under diffuser by the machining accuracy of lathe
Then lower guide bearing is loaded in diffuser in factory by seam allowance, and matches by the concentricity of bearing fit shelves and blade wheel chamber's centre of sphere
Positioning pin is beaten, lower guide bearing need to be returned factory and process seam allowance and again by building-site when pump shaft is concentric inconsistent with guide bearing
With beating positioning pin after the adjustment of scene, it is time-consuming arduously, also need to be designed, the examination & approval of management.Compared with prior art, this hair
Bright adjustable guide bearing mechanism, can be conveniently disposably in the concentric of building-site adjustment lower guide bearing and pump shaft, with playing positioning
Pin improves the convenience of water pump installation and removal, reduces installation and maintenance construction workload.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the adjustable guide bearing mechanism of the present invention；
Fig. 2 is scheme of installation of the present invention.
Specific embodiment
As shown in Figure 1, adjustable guide bearing mechanism includes lower guide bearing 1 and locating ring 2, positioning bolt 3, locking nut
4, positioning pin 5.The lower flange 1-2 of lower guide bearing 1 passes through positioning bolt 3 and locking nut 4 and 2 circumferencial direction fixing lock of locating ring
Tightly, the upper flange 1-1 of lower guide bearing 1 is fixed in diffuser on hub upper flange a by fastening bolt, and is positioned with positioning pin 5.
In-site installation in use, three diffuser, blade wheel chamber and impeller entirety are connected after hang in pump hole, adjust water
It is flat that pump shaft and impeller is connected with one heart, after impeller and blade wheel chamber gap are adjusted, according to the state after adjusting, it will position
Circle fastening bolt 2-1 and the fixed seam allowance 2-2 of locating ring are fixed in diffuser on hub lower flange b, and lower guide bearing 1 is hung in installation
In to diffuser in hub, according to pump shaft state adjusted, the gap of lower guide bearing 1 inner hole and pump shaft is adjusted, lower guide bearing 1 is made
Inner hole uniformly and meets the requirements with pump shaft gap, and 1 upper flange 1-1 of lower guide bearing and hub upper flange a bolt in diffuser are consolidated
It sets, stops seam allowance and spot welding locking nut, the method on lower guide bearing 1 under lower guide bearing 1 with positioning bolt 3 and locking nut 4
Positioning pin 5 is accomplished fluently between blue 1-1 and diffuser cooperation flange.There are unilateral with diffuser bearing guard c for the upper seam allowance of lower guide bearing 1
The adjustment gap of 0~5mm.There are the adjustment gaps of unilateral 0~8mm with locating ring bearing guard d for the lower seam allowance of lower guide bearing 1.
