Abstract
The utility model discloses a sealing structure of a sand pump. The sealing structure comprises a main shaft, an impeller, a shaft sleeve, a sealing disk and a first sealing ring, wherein the impeller is fixedly installed at one end of the main shaft; the main shaft is sleeved with the shaft sleeve; the shaft sleeve is matched with a shaft on the outer side of a shaft hole of the impeller in an airtight manner; the shaft sleeve is sleeved with the sealing disk; and the first sealing ring is located between the shaft sleeve and the main shaft. The sealing structure is characterized in that an annular groove is formed in one end of a shaft hole of the sealing disk along the periphery of the main shaft; an annular second sealing ring is embedded in the groove; a sealing cover is arranged at an opening part in the axial direction of the groove; and a third sealing ring is arranged between the inner side wall of a shaft hole of the sealing cover and the periphery of the shaft sleeve. The sealing structure has the benefits as follows: the sealing structure is reasonable in design and simple, and the sealing rings are reasonably arranged between the sealing cover and the sealing disk and the shaft sleeve as well as between the shaft sleeve and the main shaft, so that pump off of the sand pump can be effectively prevented.
Description
technical field
The utility model relates to a kind of sealing mechanism field of pump, specifically a kind of sealing configuration being applied on sand suction pump.
Background technique
The sand suction pump adopting in engineering requires very high to the tightness of drive bearing.Seal bad, easily occurring to inhale sky manifests, traditional sealing means just adopts multiple seal rings to seal main shaft and axle sleeve bearing, this kind of technology fails effectively to solve the sealing problem between axle sleeve and seal disc, not High Rotation Speed and to flowing down fortunately of sealing, there will be strong friction and the collision of current, grains of sand stream and bearing, cause the damage of bearing, have a strong impact on the life-span of husky pump.
Model utility content
For above-mentioned problems of the prior art, the utility model has increased a sealing cover, and and seal disc and axle sleeve between be provided with seal ring, thereby effectively prevented gas leakage, can effectively solve because sealing the bad loss causing.
The utility model is that the technological scheme that realizes its object employing is: a kind of sealing configuration of husky pump, comprise main shaft, be fixedly installed in the impeller of main shaft one end, be placed on main shaft and with impeller shaft hole outside the axle sleeve of shafts air-tight fit, be placed on the seal disc on axle sleeve, and be positioned at the first seal ring between axle sleeve and main shaft, it is characterized in that: one end of the axis hole of described seal disc is provided with annular groove along main shaft periphery, described groove is embedded in annular the second seal ring, described groove opening portion is vertically provided with sealing cover, between described sealing cover axis hole madial wall and axle sleeve periphery, be provided with the 3rd seal ring.
As optimization: in the middle of described sealing cover, anchor ring is provided with ring-like projection and seal disc annular groove is chimeric.
As optimization: the 3rd seal ring arranging between described axle sleeve and sealing cover be arranged two in parallel.
The beneficial effects of the utility model: the utility model is reasonable in design, simple in structure, between sealing cover and seal disc and axle sleeve and between axle sleeve and main shaft, be all rationally provided with seal ring, can effectively prevent that sand pump from finding time, prevent that the grains of sand from flowing into closed chamber, causes the loss of husky pump.
