Description
Technical Field
The utility model relates to a sealing device, exactly a mud pump sealing device.
Background
At present, the slurry pump has the defects of poor packing sealing wear resistance and corrosion resistance due to the fact that a medium has particles and is corrosive, and shaft seal leakage frequently occurs. The mud pump packing seal is modified into a K-type combined seal, the K-type combined seal comprises a framework oil seal, a water distribution ring, a silicon carbide shaft sleeve and an oil seal box, the sealing performance of the K-type combined seal is enhanced, and the machine seal water can flush impurity particles in the oil seal box and reduce abrasion. The running effect is good in the using process, the shaft seal leakage condition is reduced, but the conditions of sealing water leakage of an external machine and brittle fracture of a silicon carbide shaft sleeve exist.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a slush pump sealing device, the device can strengthen the leakproofness, avoids the quick-witted water leakage that seals, increases seal strength, prolongs the life of pump.
In order to solve the above technical problem, the utility model discloses a following technical means:
the utility model provides a slush pump sealing device, includes the axle sleeve, sets up the oil blanket box on the axle sleeve, the oil blanket box be equipped with the oil blanket chamber along the direction of axle sleeve, the oil blanket chamber is equipped with the opening at the terminal surface of oil blanket box, the oil blanket intracavity is equipped with the adjacent skeleton oil blanket that sets up of the formula of arranging, the axle sleeve is equipped with the clamp plate in the one end that is equipped with the open-ended of oil blanket box, clamp plate seal oil blanket chamber, the clamp plate is equipped with the shaft hole, the clamp plate passes.
Compared with the prior art, the outstanding characteristics are that:
the utility model discloses with the sealed middle water ring cancellation that divides of K type, change for the skeleton oil blanket, it is sealed together to increase more, strengthens the leakproofness to cancel the machine and seal water, avoid the machine to seal water leakage. And the shaft sleeve is made of stainless steel, so that the strength is improved, and the service life of the pump is prolonged. Can satisfy different slush pump sealing effects, the axle sleeve adopts stainless steel material, and the skeleton oil blanket replaces the water ring that divides and can play the sealed effect of reinforcing, the dependable performance, long service life, small, with low costs, has extensive application space and market prospect.
The further preferred technical scheme is as follows:
the framework oil seal is a self-tightening framework oil seal.
The main function of the framework oil seal in the device is to prevent medium leakage, the purpose of using the framework oil seal is to cancel machine seal water, and the framework oil seal is mainly subjected to friction in the device, so that the self-tightening framework oil seal with better wear resistance and corrosion resistance is adopted.
