Description
Technical field
The utility model relates to horizontal type multi-stage pump, proposes to manufacture horizontal multi-stage torque flow pump by torque flow pump principle.
Background technique
Existing horizontal type multi-stage pump product, mainly adopts centrifugal pump structure, the running clearance in high and low pressure chamber in pump, i.e. inlet segment, stage casing and water exit end, the matching gap between they and impeller, realizes sealing with seal ring; Multistage centrifugal pump impeller, can add up and produce very large axial force, therefore, need arrange Balance disc with balancing axial thrust, there is following shortcoming in it: produce same lift, and centrifugal pump impeller diameter more about than torque flow pump diameter 20%, causes pump volume to increase; In the usage requirement environment having variable-flow constant-pressure fluid to carry, centrifugal pump lift changes with the change of flow, can not meet usage requirement.After long-play, pump seal ring, guide blade sleeve position meeting Fast Wearing, cause pump performance to decline; Balance disc and gimbal are that a pair high-speed rotation friction is secondary, and wearing and tearing in running, it is frequent to change very soon.Due to the axial motion produced in Balance disc operation, and after Fast Wearing, rotor can produce larger axial dimension displacement, so the multistage centrifugal pump of class formation, shaft seal should not adopt sealing configuration, can only use soft packing seal, cause pump leakage rate large, efficiency reduces.
Model utility content
The utility model object is to solve the problem, and provides a kind of novel horizontal Multi-stage spiral pump, is specifically realized by following technological scheme:
A kind of novel horizontal Multi-stage spiral pump, comprise the pump housing, be connected with the rotor part of three groups of vortex pump impellers and two bearing suppories, described two bearing suppories are connected to the two ends of the described pump housing, and described rotor part runs through rotationally and to be arranged in the described pump housing and the two ends of this rotor part are connected with described bearing support respectively; The outside of the described pump housing is respectively arranged with water intake, water outlet, the middle part of the pump housing is disposed with the inlet segment chamber, stage casing chamber and the water exit end chamber that interconnect, and described three groups of vortex pump impellers lay respectively in described inlet segment chamber, stage casing chamber and water exit end chamber; Described inlet segment chamber is communicated with described water intake, and described water exit end chamber is communicated with described water outlet; Described inlet segment chamber, stage casing chamber are eddy flow pump type chamber, and the distance apart from corresponding chambers on front side of described vortex pump impeller is 3-5 millimeter, and described vortex pump impeller is provided with corresponding back blades.
Described novel horizontal Multi-stage spiral pump, it designs further and is, is provided with the deep groove ball bearing supporting described rotor part in described bearing support.
Described novel horizontal Multi-stage spiral pump, it designs further and is, described water exit end chamber is connected with the reverse Seal cage of water outlet.
Described novel horizontal Multi-stage spiral pump, it designs further and is, the bearing support being connected to pump housing water outlet direction is connected with described water exit end chamber.
The beneficial effects of the utility model are: the utility model does not establish seal ring, and without sealing running clearance, the running clearance not depositing the pump housing and impeller upon wear increases thus the problem causing pump performance to decline; Impeller establishes back blades, with automatically balancing axial force, correspondingly, eliminates Balance disc and the gimbal of conventional construction, eliminates the structure of balance cylinder simultaneously; Bearing support installs deep groove ball bearing, to bear residual axial force and to ensure that rotor is without axial motion.
Accompanying drawing explanation
Fig. 1 is example structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with Figure of description and embodiment, the utility model is further described:
As shown in the figure, this novel horizontal Multi-stage spiral pump comprises the pump housing 1, is connected with the rotor part 6 of three groups of vortex pump impellers 7 and two bearing suppories 5, two bearing suppories 5 are connected to the two ends of the pump housing, and rotor part runs through rotationally and to be arranged in the pump housing and the two ends of this rotor part are connected with bearing support respectively; The outside of the pump housing is respectively arranged with water intake 11, water outlet 12, the middle part of the pump housing is disposed with inlet segment chamber 2, stage casing chamber 3 and water exit end chamber 4, the three groups of vortex pump impellers interconnected and lays respectively in inlet segment chamber, stage casing chamber and water exit end chamber; Inlet segment chamber is communicated with water intake, and water exit end chamber is communicated with water outlet; Inlet segment chamber, stage casing chamber are eddy flow pump type chamber, distance apart from corresponding chambers on front side of vortex pump impeller is 3-5 millimeter, do not establish seal ring, without sealing running clearance, the running clearance not depositing the pump housing and impeller upon wear increases thus the problem causing pump performance to decline; And vortex pump impeller is provided with corresponding back blades, with automatically balancing axial force, correspondingly, eliminate Balance disc and the gimbal of conventional construction, eliminate the structure of balance cylinder simultaneously.
The deep groove ball bearing 51 of supporting rotor parts is installed to bear residual axial force and to ensure that rotor is without axial motion in bearing support 5.
Water exit end chamber is connected with the reverse Seal cage of water outlet, and because rotor is without axial motion, sealing can as required, dress mechanical seal or packing seal.
Owing to eliminating the stuffing box body for Compositional balance room of conventional construction, the bearing support being connected to pump housing water outlet direction is directly connected with water exit end chamber, makes overall structure more compact.
