Description
Technical field
The utility model belongs to the industrial pump field, particularly relates to advancing side under a kind of and going out vertical centrifugal pump.
Background technique
At present, enter down the pump cover top that side goes out vertical centrifugal pump and also be provided with independently bearing support structure, cause the centrifugal pump lower-upper length bigger, structure is not compact.And the mode of centrifugal pump main shaft by the lengthening main shaft directly link to each other with motor, and the ability of offset angle displacement and radial displacement is relatively poor, directly with the conduct vibrations of motor to centrifugal pump, be unfavorable for that the long-term stability of body is moved.Centrifugal pump is mainly wall-hanging installation in addition, and the flexibility of mounting type is relatively poor.Adopt rigidly connected mode that centrifugal pump is installed, its damping performance is relatively poor, is unfavorable for the long-term stability operation of unit.
Summary of the invention
The utility model provides a kind of compact structure for solving the technical problem that exists in the known technology, operates steadily, the following of good reliability advance side and go out vertical centrifugal pump.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: advance side under a kind of and go out vertical centrifugal pump, comprise the pump housing, pump cover, impeller, axle, base, hitch, mechanical sealing assembly, bearing, it is characterized in that: hitch is connected by elastic component with base, the pump housing is packed on the hitch, be connected by bolt between the pump housing and the pump cover, be provided with bearing bore and Seal cage in the pump cover, be installed with diaphragm coupling on the axle from top to bottom successively, bearing, mechanical sealing assembly and impeller, wherein Bearing Installation is in bearing bore, mechanical sealing assembly is positioned at Seal cage, by first seal ring seal, pass through second seal ring seal between the impeller and the pump housing between impeller and the pump cover.
The utility model can also adopt following technological scheme: described elastic component comprises connecting bolt, steel bushing, elastomer block, elastic sleeve, steel bushing is the cylindrical part that has disk, steel bushing is sleeved on the bolt, and the flange of steel bushing and the head adjacent of bolt, steel bushing is set with elastic sleeve outward, in the hole that elastic sleeve and interior steel bushing thereof and bolt are installed on hitch, elastomer block is sleeved on outside the elastic sleeve, and respectively is provided with an elastomer block up and down at hitch.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, promptly is connected by elastic component between hitch and the base, can reduces unit vibration, thereby help to turn round steadily, reliably; The layout of bearing support structure is saved in bearing bore, Seal cage and pump cover integrated design, makes axial arrangement compacter; Shaft extension and motor shaft extension are connected by the lengthening diaphragm coupling, have substituted the structure of common extension shaft, and its compensating axial, angular displacement ability are big, and energy absorbing, vibration isolation.This structural configuration is compact, can overhaul under the situation of not tearing motor, motionless pipeline open, can better meet user's requirement.Except that vertical installation, also can realize wall-hanging installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the schematic representation of pump cover, bearing bore, Seal cage integral structure; Fig. 3 is the structural representation of elastic component.
Among the figure: 1, the pump housing; 2, pump cover; 3, impeller; 4, second seal ring; 5, first seal ring; 6, axle; 7, bearing; 8, bearing gland; 9, lengthening diaphragm coupling; 10, base; 11, hitch; 12, mechanical sealing assembly; 13, elastic component; 13-1, elastomer block; 13-2, steel bushing; 13-3, elastic sleeve; 13-4, connecting bolt; 14, escape pipe.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1 to Fig. 3, advance side under a kind of and go out vertical centrifugal pump, comprise the pump housing 1, pump cover 2, impeller 3, axle 6, base 10, hitch 11, mechanical sealing assembly 12, bearing 7, hitch is connected by elastic component 13 with base, the pump housing is packed on the hitch, be connected by bolt between the pump housing and the pump cover, be provided with bearing bore and Seal cage in the pump cover, be installed with lengthening diaphragm coupling 9 on the axle from top to bottom successively, bearing, mechanical sealing assembly and impeller, common formation rotor assembly, wherein Bearing Installation is in the bearing bore of pump cover, mechanical sealing assembly is positioned at the Seal cage of pump cover, by 5 sealings of first seal ring, seal by second seal ring 4 between the impeller and the pump housing between impeller and the pump cover.
Wherein, the static components of mechanical sealing assembly is installed in pump cover in the hole of impeller, and moving ring assembly is located on axle by the wheel hub of impeller, and middle cavity place has drain boles, and drain boles is provided with escape pipe, and the liquid of leakage can be discharged from escape pipe 14.
In addition, motor is fixed in the top of hitch, and the motor shaft extension is stretched by lengthening diaphragm coupling 9 with pump shaft and is connected.
Described elastic component comprises connecting bolt 13-4, steel bushing 13-2, elastomer block 13-1, elastic sleeve 13-3, steel bushing is the cylindrical part that has disk, steel bushing is sleeved on the connecting bolt, and the disk of steel bushing and the head adjacent of connecting bolt, steel bushing is set with elastic sleeve outward, in the hole that elastic sleeve and interior steel bushing thereof and bolt are installed on hitch, elastomer block is sleeved on outside the elastic sleeve, and respectively is provided with an elastomer block up and down at hitch.
Hitch of the present utility model and base are weldment, and hitch is welded by last lower steel plate and four angle steel, and simple in structure, service clearance is big.Because axial arrangement is compact, therefore, under motionless motor situation, pull down the bolt that unclamps behind the lengthening diaphragm coupling between the pump cover and the pump housing, just whole rotor assembly can be taken out, repair or replace part.
Adopt the lengthening diaphragm coupling to be connected between pump shaft and the motor shaft, its compensation radially, the angular displacement ability is big, and energy absorbing, vibration isolation, and the additional load that acts on the connection device is little.Fixed by elastic component between hitch and the base, its elastic element all has weakening preferably, reduces the ability of noise, in addition, axial dimension is short, and bearing can effectively equilbrium running produces radially reaches axial load, thereby has guaranteed operating steadily of pump.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
