Abstract
A unit construction centrifugal pump with easy-to-disassemble axil, including pump body (1), impeller (2), electric motor (12), coupling (10), connection frame (8), pump shaft (14), mechanical sealing device (3), etc. which is characterized in that the coupling (10) is permanent connected to shaft of the electric motor (12), one end of pump shaft (14) having a flange and being permanent connected with the coupling (10). Using the utility model, when the pump shaft wears just discharges the connecting bolt between pump shaft flange and coupling so as to maintain or replace the pump shaft expediently instead of replacing the whole motor shaft and roter, convenient use and simple structure, which can be widely used in types of horizontal or pipeline construction centrifugal pump.
Description
Technical field:
Axis easily-dismantled type direct connected centrifugal pump the utility model relates to a kind of centrifugal pump, and particularly a kind of axis easily-dismantled type direct connected centrifugal pump is the improvement of prior art.
Background technique:
In the prior art, direct connected centrifugal pump is general main by the pump housing, place impeller, motor in the pump housing, one end has the pump cover of center hole and the link press span of fixedlying connected with motor with pump housing fixed seal connection, the other end, the pump shaft that pass that center hole, an end are fixedlyed connected with impeller, the other end and motor reel is connected as a single entity, be arranged in the center hole, the mechanical seal device of pump shaft outer circumferential face, and composition is put in the pressure plug and the venting that are installed on the pump housing; Because the pump shaft the other end and motor reel are connected as a single entity, that is pump shaft is the motor reel that extends, and product in use, after flimsy pump shaft wearing and tearing, pump shaft must be changed in the lump together with motor reel and motor rotor part, like this, not only cause the loss of stop work and production to the user, and maintenance difficult, the expense costliness, and bring unnecessary loss, particularly when pumping different medium, pump shaft damages then must change whole motor, and waste is big, the user cost height, practicability is relatively poor.
Summary of the invention:
The purpose of this utility model is, not only can be connected but also separable two sections by pump shaft and motor shaft are changed into, thereby a kind of pump shaft convenient maintenance and replacement, axis easily-dismantled type direct connected centrifugal pump that user cost is low are provided.Content of the present utility model is: a kind of axis easily-dismantled type direct connected centrifugal pump, by the pump housing, place the impeller in the pump housing, motor, one end have center hole pump cover and with pump housing fixed seal connection, the link press span that the other end is fixedlyed connected with motor, pass center hole, the pump shaft that one end is fixedlyed connected with impeller, be arranged in the center hole, the mechanical seal device of pump shaft outer circumferential face, the pressure plug and the air relief cock that are installed on the pump housing are formed, its feature part is: going back socket on described motor (12) axle and being connected with the outer end by screw has the coupling of flange plate (13) (10), the other end of described pump shaft (14) also has flange plate (6) fixedly connected or that be connected as a single entity, and this flange plate (6) is bolted to connection with the flange plate (13) of described coupling (10).In the utility model content: also be provided with thermal insulating pad (7) between described flange plate (6) and the flange plate (13).In the utility model content: also be provided with thermal insulating pad (9) between described link press span (8) and the motor (12).Compared with prior art, the utlity model has following characteristics: (1) is when pump shaft wearing and tearing palpus maintain and replace, unloading the bolt that connects two flange plate separates two flange plate, can take out pump easily and take out maintain and replace, and need not change motor, motor shaft or rotor, easy to maintenance, to use into ice and obviously reduce, the product practicability obviously strengthens; (2) structure is very simple, and cost of production is low, and is easy to install, and that product operates steadily, vibrates is little, noise is low, floor space is little, energy consumption is low, efficient is high, can be widely used in various horizontal or pipe type direct connected centrifugal pump.Need not keep in repair, protection, life-span be long.
Description of drawings:
Fig. 1 is the utility model example structure schematic representation.
Embodiment:
Be an embodiment of the present utility model below.Referring to accompanying drawing.A kind of axis easily-dismantled type direct connected centrifugal pump, mainly by the pump housing 1, place the impeller 2 in the pump housing 1, motor 12, be socketed in that 12 on motor is gone up and fixedly connected and there is the coupling 10 of flange plate 13 outer end by 12 on screw 11 and motor, one end have center hole 15 pump cover and with the pump housing 1 fixed seal connection, the link press span 8 that the other end is fixedlyed connected with motor 12, pass center hole 15, one end is fixedlyed connected the other end with impeller 2 have the pump shaft 14 of the flange plate 6 that is connected as a single entity, be arranged in the center hole 15, the mechanical seal device 3 of pump shaft 14 outer circumferential faces, and the pressure plug 5 and the air relief cock 4 that are installed on the pump housing are formed; Described flange plate 6 is bolted to connection with the flange plate 13 of described coupling 10, is provided with thermal insulating pad 7 between described flange plate 6 and the flange plate 13.Be provided with thermal insulating pad 9 between described link press span 8 and the motor 12.During use, actuating motor 12,12 rotations synchronously of pump shaft 14 and motor, this centrifugal pump work.When pump shaft 14 wearing and tearing must maintain and replaces, take off the pump housing 1, impeller 2, unload the connecting bolt of lower flange 6 and flange plate 13, promptly replaceable pump shaft 14 uses maintenance very convenient.
Claims (3)
