Part abrasion is more serious, and service life is generally relatively low, while increase use and maintenance cost, reduces production efficiency and economic effect
Benefit.Due to the factor that arrival end flows back in Pulp pump running, the abrasion of flow passage components is the most serious with impeller and apron plate,
The rate of wear is 2 to 3 times of other positions.
There are two distinct issues in structure design for the traditional Pulp pump of this applying working condition.First：Tradition
Slurry pump impeller and apron plate between using angie type sealing, it is impossible to realize the sealing of approximate " zero clearance ", sealing effectiveness is paid no attention to
Think, serious wear, backflow are increased after operation a period of time, pump hydraulic performance decline, efficiency reduction, power consumption increase.Second：When need
When adjusting the gap of impeller and apron plate will termination of pumping first, the bolt for compressing bearing assembly is unclamped, by adjustment bolt
Nut moves bearing assembly to adjust gap.This adjustment mode workload is big, especially for being bothered very much for mammoth pump,
And termination of pumping will interrupt whole production procedure, have a strong impact on production efficiency, cause economic loss.
Therefore sealing effectiveness between impeller and apron plate how is improved, and just can be with the case where that need not shut down
The gap of adjustment between the two is the big technical barrier in Pulp pump structure design.
Utility model content

The service life of impeller and apron plate, greatly reduces machine stop times, reduces maintenance and operating cost.
To solve the above problems, the technical solution of the utility model is a kind of applied to adjustable in metal inner lining Pulp pump
The high-efficiency abrasion-proof disk device of section, the device includes the adjustable Wear resistance disk being arranged on apron plate, before the Wear resistance disk is located at
Between backplate and impeller, the Wear resistance disk is provided with cylinder, and the cylinder contacts the regulation outside the pump housing by the hole on apron plate
Bolt, the Wear resistance disk is limited close to impeller and by means of the fixed of regulating bolt upper locking nut by means of the ejection of regulating bolt
It is made away from impeller, sealing mechanism is provided with the hole on described apron plate.
It is preferred that, sealing mechanism includes sealing shroud, and the sealing shroud is located between cylinder and apron plate, the sealing shroud set
It is described on the cylinder and both are combined into one structure, sealing ring of the outer surface provided with multiple tracks annular of the sealing shroud
Sealing ring is spaced apart along the length direction of sealing shroud, and the sealing ring is squeezed in the hole of apron plate, and has Suitable compression
Amount.
It is preferred that, the cylinder combines to form integrative-structure with sealing shroud and sealing ring by the sulfuration process of rubber.
It is preferred that, the material of the Wear resistance disk is rich chromium cast iron.
It is preferred that, the material of the regulating bolt is stainless steel.
It is preferred that, the material of the sealing shroud is elastic caoutchouc.
The utility model beneficial effect is that adjustable high-efficiency abrasion-proof disk device that the utility model is used can be realized
The gap between Wear resistance disk and impeller is adjusted in Pulp pump running, the service life of impeller and apron plate is extended, greatly
Machine stop times are reduced greatly, maintenance and operating cost is reduced.The application of the device can make Pulp pump continuous service in design
Operating point, solve a big technical barrier of pump performance degradation caused by impeller and apron plate abrasion.Wear resistance disk is with before
Unique sealing means are to meet the requirement in the convenient regulation Wear resistance disk of running between backplate, during also can guarantee that use
Slurry is not revealed in pump chamber.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：Such as Fig. 1 and Fig. 2 institutes
A kind of adjustable high-efficiency abrasion-proof disk device applied in metal inner lining Pulp pump shown, the device includes being arranged at apron plate
Adjustable Wear resistance disk 2 on 1, the Wear resistance disk 2 is located between apron plate 1 and impeller 3, and the Wear resistance disk 2 is provided with cylinder
5, the cylinder 5 contacts the regulating bolt 6 outside the pump housing by the hole on apron plate 1, and the Wear resistance disk 2 is by means of regulating bolt 6
Ejection close to impeller and limit it away from impeller by means of the fixation of the upper locking nut 7 of regulating bolt 6, in described apron plate
Sealing mechanism is provided with hole on 1.
Sealing mechanism includes sealing shroud 8, and the sealing shroud 8 is located between cylinder 5 and apron plate 1, the sealing shroud 8 and institute
State cylinder 5 to be structure as a whole, the sealing ring 11 of the outer surface of the sealing shroud 8 provided with multiple tracks annular, the sealing ring 11 along
The length direction of sealing shroud 8 is spaced apart, and the sealing ring 11 is squeezed in the hole of apron plate 1, and has suitable decrement.
