Description
Technical field
The utility model relates to a kind of slag stock pump, is specifically related to a kind of impeller clearance regulating device of slag stock pump.
Background technique
The slag stock pump is a kind ofly to produce centrifugal force by impeller rotation, and the kinetic energy of solidliquid mixture is increased, thereby is used for carrying continuously the equipment of solidliquid mixture, is widely used in fields such as metallurgy, coal, ore dressing.The slag stock pump generally can be divided into two kinds of horizontal slag stock pump and vertical slag slurry pumps by pump shaft.Common slag stock pump structure comprises pump shaft 1 and the bearing unit that is used to support pump shaft as shown in Figure 1, and bearing unit is installed in the beam barrel 2, and beam barrel 2 is arranged on the support 3; The front end of pump shaft is equipped with the impeller 5 that is arranged in the pump housing 4.During the work of slag stock pump, because rotation impeller 5 rotations of pump shaft 1, thereby produce centrifugal force the solidliquid mixture in the pump housing is extruded from discharge port 7, the solidliquid mixture at material feeding mouth 6 places can be pushed down in the pump housing in the effect of atmospheric pressure simultaneously, thereby finishes the continuous conveying of material.The slag stock pump in the course of the work, since in the solidliquid mixture burn into solid granule of liquid medium wash away and the high speed rotating process in the wearing and tearing of impeller, gap between impeller and the pump case interior lining panel can increase gradually, and then the whole efficiency of slag stock pump is descended.Therefore,, must regularly adjust the gap between impeller and the apron plate, it is remained between 0.75mm ~ 1.00mm in order to guarantee the efficient operation of slag stock pump.
The device of traditional adjustment impeller clearance as shown in Figure 2.The bottom of beam barrel 2 is provided with the adjustment snap ring 8 that is used to adjust beam barrel present position on support 3, and support 3 is provided with and adjusts the adjustment bolt 10 of snap ring 8 screw-thread fit, and the both sides of adjusting snap ring 8 are provided with one respectively and are used to locate the nut 9 of adjusting snap ring 8.When impeller front end excesssive gap need be adjusted, at first unclamp the hold-down bolt 11 that is used for fastening beam barrel 2 and support 3 and be used to locate the nut 9 of adjusting snap ring 8, adjust bolt 10 by rotation then and make 8 reaches of adjustment snap ring, thereby drive pump shaft 1 reach in beam barrel 2 and the beam barrel, thereby make impeller front end gap smaller.When the preceding splaying of impeller is adjusted to after 0, bolt 10 is adjusted in counterrotating again, makes the preceding splaying of impeller increase to 0.75mm ~ 1.00mm.The nut 9 and the hold-down bolt 11 of snap ring both sides adjusted in locking at last, and the axial position of beam barrel 2 is fixed, and can finish the adjustment task.
But in above-mentioned adjustment process, the impeller clearance increases in the process of specified value, owing to do not measure accurately and positioning device, can only roughly estimate by rule of thumb, is difficult to accurate adjustment, also just is difficult to guarantee the whole efficiency of slag stock pump.And the process of adjusting the impeller clearance generally needs shutdown operation, safeguards that the impeller clearance, back do not adjust to suitable scope if shut down, and just delayed the time of producing and safeguarding, reduced efficiency.
The model utility content
The utility model technical issues that need to address provide a kind of slurry pump impeller lash adjusting device, make the impeller clearance can adjust to suitable scope accurately, thereby raise labour efficiency, and keep slag stock pump high-efficient operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of slurry pump impeller lash adjusting device, comprise the adjustment snap ring that is arranged at beam barrel bottom and be arranged on the support and the adjustment bolt of adjusting the snap ring screw-thread fit, be positioned at the both sides of adjusting snap ring on the described adjustment bolt and be provided with one respectively and be used to locate the nut of adjusting snap ring; It is characterized in that: described support and the corresponding end face of adjustment bolt head are provided with and adjust the dial of bolt concentric; The exterior edge face of described adjustment bolt head is provided with the index line that is used to indicate the dial scale.
Because the technological progress of having adopted technique scheme, the utility model to obtain is as follows.
The utility model is simple in structure, and is easy to operate, when adjusting the impeller clearance, can more accurately the impeller clearance be adjusted to suitable scope, saved maintenance time, improved efficiency.

Fig. 3: structural representation of the present utility model.
Fig. 4: the front view of dial in the utility model.
Wherein: 1. pump shaft, 2. beam barrel, 3. support, 4. pump case, 5. impeller, 6. material feeding mouth, 7. discharge port is 8. adjusted snap ring, and 9. nut is 10. adjusted bolt, 11. hold-down bolts, 12. dials.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further to describe in detail:
A kind of slurry pump impeller lash adjusting device, its structure comprise and adjust snap ring 8 and adjust bolt 10 as shown in Figure 3.Adjust the bottom that snap ring 8 is fixedly connected on beam barrel 2, adjust bolt 10 and pass support 3 and adjust snap ring 8 screw-thread fit, be positioned at the both sides of adjusting snap ring 8 on the adjustment bolt 10 and be respectively arranged with two nuts 9, be used for the location and adjust snap ring.
A dial 12 is installed on the exterior edge face of support 3, and dial 12 is a ring, its center of circle and the axis coinciding of adjusting bolt 10.The structure of dial as shown in Figure 4, dial is marked with graduation line, and a circumference is divided into 100 little lattice.Be carved with an index line on the head end of adjusting bolt, this index line has obvious color, to make things convenient for indicating graduation.The pitch of supposing adjustment bolt 10 is d, adjusts little lattice of bolt 10 every rotations, and the impeller clearance will increase or reduce 0.01 * d, can realize the meticulous adjustment of impeller clearance like this.
