Abstract
The utility model provides a sand-leakproof sealing device, which comprises a rubber seal ring and a sealing friction disc, wherein the rubber seal ring is annular and concave inside, and the sealing friction disc and the rubber seal ring are closely connected. When in operation, the rubber seal ring rotates along with a shaft while the sealing friction disc maintains stationary; and the rubber seal ring can also be polygonal, is mounted on the shaft and rotates along with the shaft when in operation. The rubber seal ring and the sealing friction disc are abraded to a certain extent after a certain period of operation as friction is performed therebetween; and the rubber ring is tightly attached to the friction disc due to elasticity thereof and external force, thereby greatly prolonging the service life.
Description
Affiliated technical field:
The utility model relates to a kind of seal arrangement, the definite husky seal arrangement of a kind of sand suction pump leakproof of saying so.
Background technique
Continuous development along with the sand suction pump technology, its sealing durability also needs further raising, at present, mostly the leakproof sand of known sand suction pump is directly to be enclosed within on the axle by rubber sleeve, husky pump shaft high speed rotating when work, and rubber seal is motionless, axle and seal ring bad student friction, because rubber seal does not have external force and presses, will be gapped after friction a period of time, seal ring does not just have the effect of sealing, the grains of sand will enter from the gap in the bearing, damage bearing, at this moment just must take husky pump greatly about one month at present normal working life, change seal ring, so just influence working efficiency, and the cost height, make troubles to use.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art exactly, improves a kind of improved seal arrangement, and it is rational in infrastructure that it is had, cooperate tightly, and good sealing effect, and increase working life more than 4 times.
The technological scheme that its technical problem that solves the utility model adopts is: the husky seal arrangement of a kind of leakproof, form by rubber seal and seal friction dish, it is characterized in that: described rubber seal is a ring, and in the annulus is spill, seal friction dish and rubber seal are combined closely, rubber seal and axle rotation together when work, the seal friction dish is motionless, and described rubber seal also can be polygonal.
Rubber seal is installed on the axle, rotates together with axle during work.Rub between rubber seal and the seal friction dish, after work a period of time, rubber seal and friction disk all have certain wearing and tearing, because rubber ring is flexible, also can be attached to tightly on the friction disk so there is external force to push down it again, so just increase its working life widely.
Description of drawings:
Fig. 1 is the rubber seal plan view
Fig. 2 is the rubber seal rear view
Fig. 3 is the cross section enlarged view of rubber seal
Fig. 4 is a seal friction dish plan view
Embodiment
In husky pump installation process, rubber seal shown in Figure 1 is inserted in the axle, be fixed on earlier in the husky pump housing the seal friction dish is shown in Figure 2, another side at the husky pump housing also earlier fixes the seal friction dish, one side being loaded onto the axle sleeve of rubber seal goes in the pump housing, then the another side direct-axis at the pump housing is inserted in rubber seal by opposite direction, one side is installed pump case, compress with screw, another side is installed impeller along screw thread, rubber seal is tightly pushed down, between rubber seal and friction disk, put into moderate lubrication oil.Axle and rubber seal synchronous high-speed rotation during work, rub between the edge of rubber seal and the friction disk, after work a period of time, friction disk just returns and is ground with circular groove, because rubber seal is flexible, there is external force to press again,, continues to play seal action so the edge of rubber seal also can paste in the groove tightly.
Claims (2)
1, the husky seal arrangement of a kind of leakproof, be made up of rubber seal and seal friction dish, it is characterized in that: described rubber seal is a ring, and is spill in the annulus, seal friction dish and rubber seal are combined closely, and the rotary seal friction disk is motionless together for rubber seal and axle when work.
2, the husky seal arrangement of leakproof according to claim 1, it is characterized in that: described rubber seal is a polygonal.
