Abstract
The utility model discloses a liquid conveying mechanical device used in chemical equipment. The suspension self-adjusting vertical vortex pump is on the basis of the structure of a present vertical vortex pump. The lower part of a pump shaft is changed into a straight through shaft, and an impeller is sheathed at the lower part of the pump shaft by slide fit. In addition, the inner of a pump cover is additionally provided with a lower guide bearing which is used for supporting the lower end of the pump shaft. The suspension self-adjusting vertical vortex pump not only has the advantages of simple structure, easy manufacture and low manufacture difficult but also has the advantages of stable running, reliable operation and long-term safe running when the utility model is operated.
Description
The utility model relates to a kind of thing liquid conveying mechanism device.It is widely used among the chemical industry equipment.
Peripheral pump is a kind of small flow, high-lift transfer pump.Existing vertical peripheral pump is made up of overcurrent part, drive part and hermetic unit.Wherein overcurrent part is formed by flow passage components such as the pump housing, pump cover, impeller and by their formed ring runners.Drive part then is made up of parts such as motor cabinet, pump shaft, bearings.Hermetic unit is made up of parts such as Stuffing box, filler, pads.There are two deficiencys in present vertical vortex pump structure.As can be seen from Figure 1 one be pump impeller (3) the upper-end surface with the axle (2) the shaft shoulder lean on mutually.The lower end surface of impeller (3) then is locked in impeller (3) on the axle (2) by impeller nut (4).And on pump cover (6), be provided with an adjusting screw (5).This just structure, the impeller both ends of the surface just can only be decided by the axial dimension of axle (2), the pump housing (7), pump cover (6), adapter parts such as (8) with the gap of pump cover (6) inwall and the pump housing (7) inwall respectively, again because the axle of vertical peripheral pump is all longer, therefore the control of its axial dimension is just very difficult, can cause impeller two side clearances to be difficult to adjust like this, can't make impeller be in optimum Working.The lower end of the axle in the existing structure is not provided with bearing in addition, makes the lower end of axle be in cantilever position.So the lower end of axle can be subjected to bigger radial force when work.Thereby axle is produced amount of deflection, and cause the impeller beat.When the impeller beat is serious, can make the friction that bumps between the impeller and the pump housing, even stuck phenomenon.Thereby cause the accident parking.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and provide that a kind of easy processing, manufacture difficulty are low, simple in structure, running steadily, reliable operation, the vertical peripheral pump of suspension self-regulated that two side clearances of the impeller and the pump housing can evenly be adjusted automatically.
The purpose of this utility model reaches by following measure: the vertical peripheral pump of this suspension self-regulated is on the architecture basics of existing vertical peripheral pump, and one changes the step axle of pump shaft bottom into diameter straight-through axle; It two is contained in the bottom of pump shaft with impeller set, allow it with pump shaft between cooperate to adopt and be slidingly matched, and on the end face of impeller, be drilled with the balance through hole.It three sets up down guide bearing in pump cover, allow down the lower end of guide bearing supporting pump shaft.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structural drawing of existing vertical peripheral pump bottom.
Fig. 2 is the structural drawing of the utility model bottom.
Fig. 3 is the structural drawing of the utility model integral body.
The utility model is described in further detail below in conjunction with embodiment: the vertical peripheral pump of this suspension self-regulated is made up of flange plate (2), connecting plate (11), adapter (8), the pump housing (7), pump shaft (2), upper and lower guide bearing (1,9), impeller (3), pump cover (6).Wherein flange plate (12) is positioned on the connecting plate (11).Take over (8) and be connected between the pump housing (7) and the connecting plate (11), and adapter (8) covers the middle part and the top of whole pump shaft (2).The bottom of pump shaft (2) is isometrical straight-through axle.And impeller (3) is drilled with balance through hole (10) on its end face.Last guide bearing (1) is installed in the pump housing (7).And guide bearing (9) is installed in the pump cover (6) down, and allows lower bearing (9) that the lower support of pump shaft (2) is lived.Also adopt to be slidingly matched in addition and impeller (3) is sleeved on the centre of pump shaft (2) bottom.
This peripheral pump is in case under the drive of motor, and its impeller will rotate with pump shaft.The liquid that is transferred simultaneously also has necessarily impeller and upwards pressure.So impeller can upwards float automatically, is in state of suspension.Because the impeller end face is drilled with the balance through hole, can make the pressure autobalance of the upper and lower end face of impeller again.Will make impeller in when work like this, its both ends of the surface automatically and the axial clearance between the pump housing, pump cover remain evenly.Thereby greatly reduce the positioning tolerance that part is made.Having increased time guide bearing in addition significantly reduces the beat of impeller and pump shaft bending deflection.Thereby improved the efficient of pump.Make the operation of pump long-term safety.
The utility model has following advantage compared to existing technology: this suspension self-adjusting vertical volute pump not only Simple in structure, handling ease, manufacture difficulty are low. And it can automatically regulate impeller two in the running Side clearance is even. Make pump stability of rotation, reliable operation, long-term safety running.
Claims (1)
1, a kind of vertical peripheral pump of being made up of flange plate (12), connecting plate (11), adapter (8), the pump housing (7), pump shaft (2), last guide bearing (1), impeller (3), pump cover (6) of suspension self-regulated is characterized in that the bottom of pump shaft (2) is the straight-through axle with diameter; Impeller (3) is sleeved on the bottom of pump shaft (2), and has balance through hole (10) on the end face of impeller (3); Descend the axis of guide (9) to be positioned at pump cover (6) in addition, the following axis of guide (9) is supporting the lower end of pump shaft (2).
