Abstract
The utility model relates to a vertical plastic lined self-sucking pump which belongs to the technical field of an industrial pump. The self-sucking pump is characterized in that a diversion lobe is arranged between a liquid inlet pipe and a liquid storage cavity; a diversion device is arranged between the liquid storage cavity and a liquid inlet cavity; a conical outer sleeve is arranged on a pump shaft; an opening of a liquid outlet pipe is provided with a check valve; an inverse conical oral ring impeller is adopted. The impeller of the utility model is an inverse sucking type impeller, no high pressure area exists in the liquid inlet cavity, the sealing performance is good, the outer sleeve of the pump shaft is fixed and is immobilized, the liquid flow in the liquid inlet cavity is stable, the efficiency of the pump is improved, and the cavitation can be avoided. The diversion lobe is adopted for leading liquid to be entered, which can prevent a bearing box from being shocked. The opening of the liquid outlet pipe is provided with the check valve which can prevent siphonage.
Description
The utility model relates to industrial pump structure, belongs to the industrial pump technical field.
Existing industrial vertical pump, constitute by motor, coupling, pump shaft, impeller, the pump housing, pump seat, bearing, bearing housing, sealing, gas-liquid separation chamber, liquid inlet pipe, drain pipe etc., in order to satisfy the chemical industry corrosion resistant requirement of pump, except general metal pump, developed stainless steel pump, clad lining (moulding) pump, nonmetal pump etc.The clad lining pump has good mechanical property again owing to both satisfied the requirement of anticorrosion anti-corruption.So obtained to apply more widely, but because all there is certain problem and shortage in the unreasonable structure of pump itself at aspects such as leakage, wearing and tearing, efficient and working lifes.
The purpose of this utility model is to provide the vertical lining of a kind of anticorrosion, good airproof performance, long service life to mould self-priming pump.
The purpose of this utility model is to realize by the improvement to existing vertical lining pump, vertical lining is moulded self-priming pump and is comprised the pump housing, pump shaft, coupling, motor, bearing, bearing housing, gas-liquid separation chamber, liquid inlet pipe, drain pipe, safety check, it is characterized in that self-priming pump is provided with shunt, the shunting lobe, taper pump shaft overcoat and inverted cone choma impeller, shunt is arranged between admission chamber and the reservoir compartment, the shunting lobe is arranged between liquid inlet pipe and the reservoir compartment, the outer set upper side of taper pump shaft is connected on the shunt, is provided with the gap between between taper pump shaft outer casing inner wall and the pump shaft and lower end and the back shroud of impeller.Said safety check is made of the valve seat in tape guide hole and the valve plug of guide, the even tap hole that distributes more than 2 around the axis hole of shunt.
The utility model novel and reasonable structure is manufactured easily, adopts inverted cone choma impeller, the impeller mouth up, reversed bay-type does not have the zone of high pressure in reservoir compartment, the admission chamber, helps the sealing of pump.Shunt and fixed taper pump shaft overcoat have been adopted; feed liquor intraluminal fluid levelling is steady, reduces cavitation phenomenons, and the shunting lobe has good buffer function; the protection bearing avoids being subjected to powerful the impact, and the medium that enters in the gap between pump shaft overcoat and the pump shaft plays the effect of sealing voluntarily.The fluid mouth of pipe is provided with safety check, avoids the generation of siphonage.
Accompanying drawing 1 is a structural representation of the present utility model, 1 pump housing, 2 impellers, 3 pump shafts, 4 pump shaft overcoats, 5 shunts, 6 seal rings, 7 liquid inlet pipes, 8 bearing housings, 9 shunting lobes, 10 bearings, 11 coupling, 12 motors, 13 safety check, 11 admission chambers, 15 reservoir compartments, 16 gas-liquid separation chamber among the figure.
Accompanying drawing 2 is a diversion structure schematic representation of the present utility model, 17 tap holes, 18 axis holes among the figure.
Accompanying drawing 3 is a shunting valve structure schematic representation of the present utility model, 19 leaf lobes, 20 bodys among the figure.
Accompanying drawing 4 is an inverted cone choma blade wheel structure schematic representation of the present utility model, 21 back shrouds, 22 chomas among the figure.
Accompanying drawing 5 is a pump shaft jacket structure schematic representation of the present utility model.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing:
The choma of impeller is designed to inverted cone, adopts metal frame and plastics to make integral type.The suction runner of impeller becomes to go up section big, and following section is little.Shunt adopts metallic plastic-lining to make, and some equally distributed tap holes are set around the axis hole.Shunting lobe, safety check adopt overall plastic material to make.Taper pump shaft overcoat is made of plastics.The contacted flow passage components of self-priming pump and medium all serve as a contrast system plastics or overall plastic making.
Claims (3)
1, a kind of vertical lining is moulded self-priming pump, comprise the pump housing, pump shaft, coupling, motor, bearing, bearing housing, gas-liquid separation chamber, liquid inlet pipe, drain pipe, safety check, it is characterized in that self-priming pump is provided with shunt, shunting lobe, taper pump shaft overcoat and inverted cone choma impeller, shunt is arranged between admission chamber and the reservoir compartment, the shunting lobe is arranged between liquid inlet pipe and the reservoir compartment, the outer set upper side of taper pump shaft is connected on the shunt, is provided with the gap between between taper pump shaft outer casing inner wall and the pump shaft and lower end and the back shroud of impeller.
