Description
Technical field
The utility model relates to a kind of dual-gripper formula rotary case pump.
Background technique
Rotary case pump is to occur in recent years and a kind of small flow of extensively promoting the use of, high-lift new pump, claims rotary-jet pump again.Present existing rotary case pump, its rotor is cantilever structure, be that rotor is connected with transmission shaft, radial force that the total weight of rotor and transmission shaft and rotor are produced in high speed rotating and axial power are only born separately by transmission shaft bearing, this structure causes the dynamic load burden of transmission shaft bearing excessive, causes the on-stream mechanical failure that very easily takes place of rotor.
The model utility content
The technical problems to be solved in the utility model is: in order to overcome the problem as described in the background art that existing rotary case pump exists because of the self structure defective, and a kind of dual-gripper formula rotary case pump through architecture advances is provided, the rotor both sides axle head of this rotary case pump all is subjected to the excellent support, spacing of bearing, and running is stable and reliable.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of dual-gripper formula rotary case pump, include the pump housing, end cap, medium turnover section member, rotor, transmission shaft and liquid collecting pipe, end cap, medium turnover section member is fixedlyed connected with the two ends of the pump housing respectively, rotor is arranged in the pump housing, transmission shaft is fixedlyed connected with the rotor axle head in end cap enters the pump housing, transmission shaft is by the bearing supporting that is arranged at end cap, another axle head of rotor is fixedlyed connected with an end of a hollow shaft, hollow shaft is by the bearing supporting that is arranged at corresponding position in the pump housing, the other end of hollow shaft is communicated with the liquid inlet channel of medium turnover section member, and the joining portion seals by Sealing, described liquid collecting pipe from rotor internal cavity via the outlet that extends to medium turnover section member in the hollow shaft, affixed with medium turnover section member static state.Hollow shaft in this dual-gripper formula rotary case pump and transmission shaft have supported rotor jointly, bear the weight of rotor and radial force and the axial force that the rotor high-speed rotation is produced, and simultaneously, hollow shaft also becomes the passage that medium flows into rotor internal cavity.
The described bearing that is arranged at supporting hollow shaft in corresponding position in the pump housing adopts ball bearing, with the good confinement rotor axial displacement takes place in running up.
The described bearing that is arranged at pump housing end cap supporting drive shaft also adopts ball bearing, and is provided with in pairs, to carry axial force and the radial force that rotor produces better in running up.
The beneficial effects of the utility model are: this dual-gripper formula rotary case pump is compared with the rotary case pump of existing rotor cantilever structure, the both sides axle head of its rotor all is subjected to the excellent support, spacing of bearing, rotor two side bearings are born the weight of rotor and radial force and the axial force that rotor is produced jointly in high speed rotating, thereby the operation process of rotor is stable, reliable, is difficult for breaking down.
