Description
Technical field
The utility model is related to monopole centrifugal blower technical field, specially a kind of monopole centrifugal blower
Rotor.
Background technology
Monopole centrifugal blower is energy in desulfurization removing nitric fume treatment, municipal sewage, biochemical treatment of industrial wastewater
Rich and influential family is consumed, while is also key equipment, invests and operating cost is accounted in preliminary project investment and later stage system O＆M and accounted for greatly very much
Than, thus improve efficiency and the stability of equipment into equipment manufacturer assault fortified position the problem of.And rotor belong to single-stage high-speed from
The core component of heart air blower is the principal element for influencing device efficiency and stability.
For monopole centrifugal blower often because of the variation of operating mode, operating point off-design value can cause efficiency to reduce,
Rotor oscillation overflows.If rotor stability is not high, it may result in rotor oscillation and be so large that abradable gas seal or oil sealing, very
To impeller is caused to be damaged with stator grazing, so as to generate serious consequence.Conventional structure single-stage high-speed air blower replaces vulnerable part
Sealing gland and oil sealing need to disassemble gear case body, lead to heavy workload, and hoisting difficulty is high.And after replacing sealing gland or oil sealing, by
It is poor in reassembling property of rotor, rotor unbalance value is caused to change, and aggravate rotor unstability.
Utility model content
The purpose of this utility model is to provide a kind of monopole centrifugal blower rotor, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical solution：A kind of monopole centrifugal blower rotor,
Including pull rod, locking nut, locating shim, impeller, high speed shaft and thrust disc；Pull rod one end connection high speed shaft, thrust disc,
The pull rod other end sequentially passes through impeller, locating shim and locking nut.
Preferably, the wheel nose end face is provided with counterweight screws threaded hole, and the impeller wheel back of the body is equipped with duplicate removal ring and opens
Slot, and axial and circumferential positioning is carried out by two-sided key connecting with high speed shaft spindle nose.
Preferably, high speed shaft spindle nose outer diameter A end uses multistage, non-contact type ladder labyrinth seal structure, thereafter B ends and oil
Envelope cooperation, high speed shaft C-terminal and E ends coordinate respectively with journal bearing, and F ends coordinate with thrust bearing, and D ends coordinate with low-speed gear,
High speed shaft right end is coupled by screw with thrust disc.
Preferably, it is radially fixed to be carried out between the thrust disc, high speed shaft, pull rod, impeller, locating shim and locking nut
Position.
Compared with prior art, the beneficial effects of the utility model are：The utility model is skillfully constructed, simple in structure, respectively
Coordinate compact between a component, impeller simultaneously can be with duplicate removal and exacerbation, convenient for dynamic balancing.The impeller wheel back of the body is using end face fixed-double bonds
The friction reliability design of+end face ensures the repeatability positioning of impeller.High speed shaft is using multistage, non-contact type ladder labyrinth seal
Gas is effectively reduced with oil enveloping structure and oil is revealed.Entire rotor portions all parts are ensured same with high speed shaft by radial positioning
The heart effectively reduces rotor oscillation amplitude, improves rotor stability.When rotor is dismounted and overhauled, only needing first will from gear-box tail portion
Thrust disc is dismantled, then left side stationary part, locking nut, locating shim, impeller, sealing gland and oil sealing are dismantled successively, it is possible to
Entire rotor is taken out from left side, and without disassembling gear-box, oil sealing and sealing gland are easily changed, easy to operate.
