Description
Technical field
The utility model relates to a kind of centrifugal pump rotor, is specifically related to a kind of centrifugal pump rotor sink.
Background technique
Centrifugal pump rotor operationally, because the friction of bearing can produce a large amount of heat, causes centrifugal pump rotor in operation process, make bearing heating up rapidly, causes bearing life to reduce, and the whole rotor part of centrifugal pump can be made to damage cause working time serious.
A kind of electric tool being beneficial to rotor heat radiation is disclosed in Chinese utility model patent (Authorization Notice No.: CN202640312U), comprise housing and be arranged on the rotor in housing, described rotor one end is fixedly connected with commutator, described rotor is provided with Air System relative to the other end of commutator connecting end, and this Air System is connected with rotor.
This electric tool being beneficial to rotor heat radiation; although a large amount of heat, dust granules and the high temperature gas flows of generation can be discharged fast smoothly; but because bearing is through whole centrifugal pump rotor device; so single fan blade cannot realize dispelling the heat to whole bearing, truly bearing cannot be protected.
Model utility content
The purpose of this utility model is the defect for above-mentioned prior art, provides a kind of centrifugal pump rotor sink, can be good at dispelling the heat to whole bearing.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of centrifugal pump rotor sink; comprise rotor body (1); it is characterized in that: described axle (18) is through whole rotor body (1); the front end and back end of described axle (18) is respectively equipped with fan blade a(4) and fan blade b(15); described fan blade a(4) by protective housing a(8) protection; described fan blade b(15) by protective housing b(12) protection, described protective housing a(8) lower end is provided with exhaust outlet a(9), described protective housing b(12) lower end is provided with exhaust outlet b(11).By establishing fan blade at axle two ends, realizing lowering the temperature to bearing, adding the stability that bearing uses, extend bearing working life, avoid the damage that bearing is unnecessary, thus avoid the unnecessary shutdown of centrifugal pump, add the working efficiency of centrifugal pump.
As further improvement of the utility model, the fan blade a(4 described in it) and axle (18) between flat key a(7 is installed) and circlip for shaft a(6); Described fan blade b(15) and axle (18) between flat key b(13 is installed) and circlip for shaft b(14).Enable fan blade stably along with axle rotates, the rotation not affecting on the one hand axle also achieves the cooling to bearing on the other hand, extends bearing working life, avoids the damage that bearing is unnecessary.
As further improvement of the utility model, axle described in it (18) extends bearing support a(10) and axis body b(19), the front end of described axle (18) is by bearing gland a(5) and bearing support a(10) fix; The end of described axle (18) is by bearing gland b(16) and bearing support b(19) fix.
As further improvement of the utility model, bearing gland a(5 described in it) and bearing support a(10) between be provided with locking nut (3).
As further improvement of the utility model, the top of rotor body described in it (1) is provided with suspension (17).
As further improvement of the utility model, bearing support a(10 described in it) front end and tail end fix respectively by bearing (2) and axle (18).
The beneficial effects of the utility model are: can dispel the heat to whole bearing; reduce bearing temperature; add the stability that bearing uses; extend bearing working life; avoid the damage that bearing is unnecessary; thus avoid the unnecessary shutdown of centrifugal pump, add the working efficiency of centrifugal pump.
