Abstract
The invention discloses a novel plastic-lined centrifugal pump, and relates to the technical field of pump valves. The novel plastic-lined centrifugal pump comprises a pump body, an impeller, a plastic pump cover, a pulling rod, an intermediate support, a hollow shaft, a bearing box combination, a locking nut and a mechanical seal, wherein the impeller is arranged in the pump body and locked at one end of the hollow shaft through the pulling rod, the other end of the pulling rod is locked on the hollow shaft through the locking nut, torque is transferred through the square opposite sides at the shaft ends of the hollow shaft to drive the impeller to rotate, and a movable ring part of the mechanical seal is fixed on the impeller in an interference fit mode. The novel plastic-lined centrifugal pump is reasonable in design, convenient to disassemble, safe and reliable.
Description
Technical field
The present invention relates to pump valve technical field, be specifically related to a kind of novel plastic-lining centrifugal pump.
Background technique
Existing common plastic-lining centrifugal pump has two kinds, A type: impeller, axle sleeve, impeller nut are Split type structure (seeing accompanying drawing 1), between its impeller and impeller nut, impeller and axle sleeve, need two seals, and leak point is many, and the safety and reliability of pump operation is poor; Type B: impeller, axle sleeve, impeller nut, impeller shaft are also overall structure, but impeller shaft and pump shaft are by taper fit and transmit knob apart from (seeing figure attached 2), its impeller shaft and pump shaft all need precision machining, required precision is high, and after this kind of actual use of pump, when pump needs repairing, taper fit place, because the reasons such as environment corrosion or machining accuracy are interlocked and cannot dismantle, brings great trouble to operator, can only scrap dismantling the parts that but can also use.
Summary of the invention
The object of this invention is to provide a kind of reasonable in design, convenient disassembly, safe and reliable novel plastic-lining centrifugal pump.
In order to solve existing problem in background technique, the present invention is by the following technical solutions: it comprises the pump housing, impeller, plastics pump cover, pull bar, intermediate support, hollow shaft, bearing housing combination, locking nut, mechanical seal, in the described pump housing, be provided with impeller, impeller fixes on hollow shaft one end by a Draw bar lock, the pull bar the other end is locked on hollow shaft by locking nut, hollow shaft transmits knob distance by the square opposite side of axle head, impeller is rotated, and mechanical sealing linkage ring part is fixed on impeller by interference fit.
The present invention compares with A, two types of common plastic-lining centrifugal pumps of B:
Compare with the common plastic-lining centrifugal pump of A type, the present invention is by becoming integrated type impeller by plastic-lining centrifugal pump impeller, impeller nut, axle sleeve Combination Design, removed two seals between the first plastic-lining centrifugal pump impeller and impeller nut, impeller and axle sleeve, reduce leak point, improved the safety and reliability of pump operation.
Compare with the common plastic-lining centrifugal pump of Type B, impeller of the present invention and hollow shaft transmit knob distance by opposite side, easily fill readily removablely, very convenient, have greatly reduced operator's working strength.And during maintenance, only need change and damage parts, reduce waste, improve plastic-lining centrifugal pump life-cycle effect and cost rate.

Fig. 1 is the structural representation of the common plastic-lining centrifugal pump of A type;
Fig. 2 is the structural representation of the common plastic-lining centrifugal pump of Type B;
Fig. 3 is structural representation of the present invention;
Fig. 4 is the structural representation of impeller;
Fig. 5 is the structural representation of steel combination inserts.
Embodiment
As shown in Figure 3, a kind of novel fluoroplastic pipeline pump, it comprises the pump housing 1, impeller 2, plastics pump cover 3, pull bar 4, intermediate support 5, hollow shaft 6, bearing housing combination 7, locking nut 8, mechanical seal 9, in the pump housing 1, there is impeller 2, impeller 2 is locked in hollow shaft 6 one end by a pull bar 4, pump cover 3 is by being fixed in the pump housing 2, pull bar 4 the other ends are locked on hollow shaft 6 by locking nut 8, hollow shaft 6 transmits knob distance by the square opposite side of axle head, impeller is rotated, during dismounting, the locking nut 8 of the locking pull bar 4 at hollow shaft 6 rear portions is come loose and unloaded, impeller 2 just can be extracted out and unload from hollow shaft 6 very like a cork, mechanical seal 9 rotating ring parts are fixed on impeller 2 by interference fit, by impeller integral design, corrosive liquids can not touch metal hollow axle 6, therefore before and after impeller, do not need to arrange again static seal.
As shown in Fig. 4-5, described impeller 2 is formed by the compacting of steel combination inserts outsourcing plastics, and steel combination inserts is welded by the sub-inserts of three independent processing, on its neutron inserts A10, leaves screw thread, for pull bar 4 locking impellers 2.
Claims (2)
1. a novel plastic-lining centrifugal pump, it is characterized in that, it comprises the pump housing, impeller, plastics pump cover, pull bar, intermediate support, hollow shaft, bearing housing combination, locking nut, mechanical seal, in the described pump housing, be provided with impeller, impeller fixes on hollow shaft one end by a Draw bar lock, and the pull bar the other end is locked on hollow shaft by locking nut, and hollow shaft transmits knob distance by the square opposite side of axle head, impeller is rotated, and mechanical sealing linkage ring part is fixed on impeller by interference fit.
2. centrifugal pump according to claim 1, it is characterized in that, described impeller is formed by the compacting of steel combination inserts outsourcing plastics, and steel combination inserts is welded by the sub-inserts of three independent processing, on its neutron inserts A, leave screw thread, for pull bar locking impeller.
