Abstract
The utility model relates to a new vertical multistage cylindrical fixing device for a condenser pump impeller and a shaft, which comprises an impeller and a pump shaft. The utility model is characterized in that the pump shaft is provided with a groove, and two semicircular impeller snap rings which are combined are arranged in the groove; the upper end surface of the impeller is attached to one side of the two semicircular impeller snap rings which are combined; the other side of the two semicircular impeller snap rings which are combined is provided with a snap ring gland connected with the impeller by a bolt; the pump shaft is provided with a key connected with the impeller; a ring formed from the two semicircular impeller snap rings which are combined is positioned on the inner side of the upper end surface of the impeller and in a semi-groove on the inner side of the gland of the snap rings. The utility model has the advantages that the looseness between the impeller and the shaft is avoided by the structural improvement of the fixing device for the impeller and the pump shaft, and the impeller and the shaft are more reliably connected.
Description
Technical field
The utility model relates to a kind of fixing device, the particularly a kind of novel vertical multi-stage cartridge type condensate extractionpump impeller and the fixing device of axle.
Background technique
The impeller of present existing vertical multi-stage cartridge type condensate extractionpump is to realize with the conical ring cover with the fixed structure of axle, but there is following shortcoming in it: impeller because of be subjected to gravity and when starting the stressed direction of liquid all downward, and because the startup of pump when frequent, it is loosening with being connected of axle to be easy to that impeller takes place, serious will cause can't running well of pump, influences the normal operation of whole production.
Summary of the invention
To be the impeller that solves vertical multi-stage cartridge type condensate extractionpump in the prior art with axle overlap with conical ring the purpose of this utility model fixedlys connected existing the problems referred to above, provide a kind of novel vertical multi-stage cartridge type condensate extractionpump impeller with spool fixing device.The utility model designs a kind of novel vertical multi-stage cartridge type condensate extractionpump impeller and the fixing device of axle, comprise impeller, pump shaft, it is characterized in that: fluted at pump shaft, two semicircle impeller snap rings that are harmonious are arranged in groove, the impeller upper-end surface is affixed on a side of two semicircle impeller snap rings that are harmonious mutually, opposite side at two semicircle impeller snap rings that are harmonious has a snap ring gland to connect impeller by bolt, has key to connect impeller on pump shaft.The ring of two semicircle impeller snap ring formations that are harmonious is positioned at half groove of the inboard, upper-end surface and the snap ring gland inboard of impeller.The utility model has the advantages that by improvement, avoided loosening between impeller and the axle, make impeller be connected more reliable with axle to impeller and pump shaft fixture structure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated,
Accompanying drawing is a structural representation of the present utility model,
Embodiment
Comprise impeller 1, pump shaft 2 among the figure, it is characterized in that: at pump shaft 2 fluted 3, two semicircle impeller snap rings 4 that are harmonious are arranged in groove 3, impeller 1 upper-end surface is affixed on a side of two semicircle impeller snap rings 4 that are harmonious mutually, opposite side at two semicircle impeller snap rings 4 that are harmonious has a snap ring gland 5 to connect impeller 1 by bolt 6, has flat key 7 to connect impeller 1 on pump shaft 2.The ring of two the semicircle impeller snap ring that is harmonious 4 formations is positioned at half groove 8 of the inboard, upper-end surface and snap ring gland 5 inboards of impeller 1.
Through the improvement of impeller 1,, give impeller 1 by 7 transmitting torques of the flat key on the pump shaft 2 by the axial force that two semicircle impeller snap rings 4 bear impeller 1 with pump shaft 2 fixed structures.Avoided loosening between impeller 1 and the pump shaft 2, it is more reliable that impeller 1 is connected with pump shaft 2, good through using effect.
Claims (2)
1, a kind of novel vertical multi-stage cartridge type condensate extractionpump impeller and the fixing device of axle, comprise impeller, pump shaft, it is characterized in that: fluted at pump shaft, two semicircle impeller snap rings that are harmonious are arranged in groove, the impeller upper-end surface is affixed on a side of two semicircle impeller snap rings that are harmonious mutually, opposite side at two semicircle impeller snap rings that are harmonious has a snap ring gland to connect impeller by bolt, has flat key to connect impeller on pump shaft.
2, by the described a kind of novel vertical multi-stage cartridge type condensate extractionpump impeller of claim 1 and the fixing device of axle, it is characterized in that: the ring of two semicircle impeller snap ring formations that are harmonious is positioned at half groove of the inboard, upper-end surface and the snap ring gland inboard of impeller.
