Abstract
The utility model discloses a wear resistant sleeve for a stirring shaft of a coal mining paste filling pump and belongs to a wear resistant sleeve for a filling pump. The wear resistant sleeve comprises a wear resistant sleeve body for the stirring shaft, a washer, two stirring shaft seals, a transparent taper reduction sleeve and a flange, wherein the wear resistant sleeve body for the stirring shaft is arranged on the stirring shaft; a seam allowance of the flange is provided with the two stirring shaft seals and the washer; the washer is located between the two stirring shaft seals; the transparent taper reduction sleeve is connected with the flange by using a bolt; and the stirring shaft is arranged in the flange. The wear resistant sleeve body for the stirring shaft is made of YG8 (tungsten steel), the hardness of the YG8 is only lower than that of diamond, and the YG8 has favorable wear resistance and heat resistance and cannot be worn, so that the surface finish of the wear resistant sleeve is well kept and the service life of each stirring shaft seal is greatly prolonged. The wear resistant sleeve has the advantages that the wear resistant sleeve body for the stirring shaft is simple in processing technique, cannot be worn, and the surface finish of the wear resistant sleeve can be well kept when the wear resistant sleeve works; and the stirring shaft seals are simple in structure and convenient to dismount and maintain.
Description
Technical field
The utility model relates to a kind of filling pump wear-resistant sleeve, particularly a kind of coal mine paste filling pump stirring shaft wear-resistant sleeve.
Background technique
At present, in the processing mode of paste body filling pump stirring shaft with wear-resistant sleeve: one, for the wearing and tearing of the alleviating wear-resistant sleeve impact on the stirring shaft sealing, use the mode of multiple-sealed combination, but this form sealing configuration is loaded down with trivial details, working life is short, detachable maintaining is complicated etc.; Two, use the wear-resistant sleeve of Biao Mian Du Chrome, the easily wearing and tearing of this structural type wear-resistant sleeve surface, working life is not long, and seal ring will soon damage when wear-resistant sleeve damages; Three, use the high alloy cover, the easily wearing and tearing of the surface of high alloy cover, after surface abrasion, seal ring will soon damage.
The model utility content
The purpose of this utility model is that a kind of coal mine paste filling pump stirring shaft wear-resistant sleeve will be provided, the working life that solves seal ring short, detachable maintaining hard problem.
Originally be that model utility realizes by following technical approach: this wear-resistant sleeve comprises: stirring shaft wear-resistant sleeve, packing ring, stirring shaft sealing, stirring shaft, transition are overlapped and flange thoroughly, the stirring shaft wear-resistant sleeve is arranged on stirring shaft, and the flange stop portion is installed two stirring shaft sealings and a packing ring; Packing ring is between two stirring shaft sealings, and transition is thoroughly applied mechanically bolt and is connected with flange, and stirring shaft is arranged in flange.
beneficial effect, owing to having adopted such scheme, the stirring shaft wear-resistant sleeve is arranged on stirring shaft, the flange stop portion fills the stirring shaft sealing successively, packing ring, the stirring shaft sealing, again bolted mode being applied mechanically in transition thoroughly is connected with flange, at last stirring shaft is arranged in flange, stirring shaft makes the stirring shaft wear-resistant sleeve along the stirring shaft seal rotary in work, the material of stirring shaft wear-resistant sleeve is YG8, be wolfram steel, YG8 has very strong hardness, the hardness of YG8 only this in diamond, good antiwear heat resisting is arranged, YG8 belongs to never wornout material, can well guarantee the surface finishment of wear-resistant sleeve, make large leap ahead in working life of stirring shaft sealing.
When stirring shaft was worked, the stirring shaft wear-resistant sleeve had improved the life-span of stirring shaft seal ring greatly along the stirring shaft seal rotary, has reached purpose of the present invention.
Advantage: the processing technology of stirring shaft wear-resistant sleeve is simple, never wornout, can well guarantee surface finishment when work; Stirring shaft place sealing configuration is simple, detachable maintaining convenient.
