Abstract
The utility model relates to a vertical pipeline pump. The discharge outlet of a pump body is horizontally concentric with a suction inlet and vertical with an axle center line. The suction chamber of the pump body is in a half spiral shape. An impeller is the back opening type impeller with a balance hole. An impeller blade and a pump cover are provided with a certain controller gap. A bearing box body and a bearing box adopt thread connection. The inner portion of a sealing chamber is provided with a flow guiding block. The utility model is characterized in that the pump efficiency is high, the axial force generated by the impeller is small, the anti-gas-corrosion performance is strong, the service life of the baring and the mechanical sealing is prolonged, the axial gap adjustment of the pump is convenient, the pump performance can be recovered after abrasion by adjustment, the repair is convenient and the repair expense is low.
Description
Technical field the utility model relates to a kind of pump, especially for the riser pump of fed sheet of a media.
Background technique is applied in the riser pump of industries such as petrochemical industry, smelting, papermaking, medicine, food processing, mainly is to be made of the pump housing, pump shaft, impeller, mechanical seal structure, bearing.The deficiency of this pump is: the axial force that impeller produces is bigger, influences bearing working life, behind the damage in impeller, can't recover its performance, can only change impeller; Washing solution in the closed chamber is moving around axial flow, and the solid particle in the liquid acts in the mechanical seal, reduces the working life of mechanical seal; The adjustment of the axial clearance of pump and the maintenance of parts need be dismantled pump and motor, are not easy to maintenance, increase maintenance cost; The anti-cavitation ability of pump is relatively poor, and efficient is low.
The summary of the invention the purpose of this utility model is the riser pump that a kind of efficient height, long service life is provided, is convenient to installation and maintenance.
The purpose of this utility model is achieved in that a kind of riser pump, comprise: the pump housing, impeller, pump shaft, mechanical seal parts, bearing part, motor frame, it is characterized in that pump housing exhaust port is concentric and perpendicular with shaft axis with the suction port level, pump housing suction chamber is a half-spiral; Impeller is the back of the body unshrouded impeller that has equalizing orifice, has certain controlled gap between impeller blade and the pump cover; Adopt between bearing housing and the bearing box and be threaded; Be provided with baffle in the closed chamber; Motor shaft is connected by coupling with pump shaft.
Lubricating cup is the forced filling oil cup that has joint.
Baffle is the wedge shape projection that is evenly distributed on the closed chamber inwall.
Pump housing top is fixedly connected with the motor frame, and the bottom is connected with the adjustable base of level.
The riser pump that the utility model provides, the design of its pump housing suction chamber has reduced the hydraulic loss of ingress, improves the anti-cavitation ability of pump, and suction port forms standardization with the concentric structure of the pump housing that makes of exhaust port level, is convenient to installation, maintenance.The back of the body unshrouded impeller that has equalizing orifice, can improve the anti-cavitation performance and the efficient of pump, balancing axial thrust to greatest extent, realize predictable seal chamber pressure and thrust load, prolonged the working life of the service cycle and the bearing of mechanical seal, back of the body unshrouded impeller also makes the pump cover cover plate become wear surface, reduces the impact of fed sheet of a media to impeller, reduces wearing and tearing.Bearing housing adopts with bearing box and is threaded, and need not take apart under the condition of pump, can adjust axial clearance exactly, recovers pump performance, and is easy to maintenance, reduces maintenance cost.For can prolonged mechanical working life of sealing, baffle is set in closed chamber, it can change the flow direction of washing solution, make liquid by moving around moving the becoming of axial flow along axial flow, help to keep the suspension of solid particle in the liquid, the erosion effect is reduced to minimum, also have stronger heat radiation simultaneously and get rid of the steam ability, with solid, gas and the heat band tool sealed member of disembarking.Lubricant oil can directly be changed outside pump, and it is convenient to change.The pump housing is fixed on the adjustable base of level, the ability of mouth of pipe load is greatly strengthened, motor shaft is connected by coupling with pump shaft, need not to move pipeline, the pump housing, motor frame and motor during maintenance, just bearing part together can be extracted out in the motor frame together with pump cover, impeller.
Compare with existing pipeline mounted pump, the utlity model has following advantage: the pump efficiency height, the axial force that impeller produces is little, and the anti-cavitation ability is strong, has prolonged the working life of mechanical seal and bearing, the axial clearance of pump is easy to adjust, still can recover its performance by adjusting behind the damage in impeller, during the disassemble or assemble bearing part, need not mobile motor, motor frame, the pump housing and pipeline, be convenient to maintenance, maintenance expenses is low.
Description of drawings Fig. 1 is a structural representation of the present utility model;
Embodiment is described further below in conjunction with accompanying drawing:
As shown in Figure 1, present embodiment provides the riser pump mainly to be made up of the pump housing 1, impeller 21, middle linkage section 6, pump shaft 17, mechanical seal parts, bearing part, motor frame 13.Pump housing exhaust port 22 is concentric and perpendicular with shaft axis with suction port 3 levels, and pump housing suction chamber 2 is a half-spiral, and delivery chamber 4 is a spirality.There is 0.5 millimeter controlled gap in impeller 21 for having the back of the body unshrouded impeller of equalizing orifice between impeller blade and the pump cover 5.Axle sleeve 19 outsides of pump shaft are provided with mechanical seal, and seal form can be filler, single envelope, two envelope, series seal etc., and closed chamber is to be evenly distributed with baffle 20 on the center hole wall of pump cover, and baffle is and hole wall all-in-one-piece wedge shape projection.Bearing part is made up of bearing housing 9, bearing box 15, bearing 8,10, and bearing housing adopts with bearing box and is threaded, and rotates by anti-turn screw 14 restriction bearing boxs, is cast with graduated scale will on the bearing box.The end that is located at the bearing 10 in the bearing box is spacing by bearing pressure ring 16.Be provided with bearing enclosure 7 between bearing housing and the axle.Pump shaft is connected with motor shaft by coupling 12, and motor frame 13 is fixedly connected on the pump housing, and with component covers such as bearing housings within it.Pump housing bottom is connected with base 24.Lubricating cup 11,18 is for having the forced filling oil cup of joint.23 is pump housing choma.
