The invention provides a dry-wear-resistant sealing part. The dry-wear-resistant sealing part comprises a shaft sleeve, the shaft sleeve is sequentially sleeved with a fixing base, a static ring base,a static ring, a movable ring, a spring base, a spring and a movable ring base from left to right, the left end of the movable ring abuts against the right end of the static ring, one end of the spring abuts against the movable ring base, the other end of the spring abuts against the spring base, the spring base and the movable ring base are coated with sealant sleeves, the fixing base and the static ring are spaced, the inner diameter of the static ring seat is larger than the outer diameter of the shaft sleeve, and the two ends of the static ring seat are arranged outside the fixing base and the static ring in a sleeving manner correspondingly, so that a gap is formed between the inner wall of the static ring base and the outer wall of the shaft sleeve, a section of heat dissipation cavity is formed in the gap, multiple clamping teeth are distributed on the outer side of the movable ring, multiple first position clamping grooves are formed in the inner wall of a movable ring mounting groove, the clamping teeth are inserted into the first position clamping grooves, and the widths of the first position clamping grooves are larger than those of the clamping teeth, so that the movable ring can rotate in the spring base; and a linkage clamping structure is arranged between the spring base and the movable ring base. The service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a dry wear-resistant seal. Background technique [0002] Mechanical seals are one of the basic components of machinery with precision and complex structures, and are key components of various pumps, reaction synthesis kettles, turbo compressors, submersible motors and other equipment. However, common mechanical seals need to add lubricating oil from time to time. Once the lubricant is missing, it is easy to wear the seal and cause liquid leakage. Contents of the invention [0003] The present invention aims at at least solving the technical problems existing in the prior art, and particularly innovatively proposes a dry wear-resistant seal, which can withstand dry wear and improve the durability of the seal. [0004] In order to achieve the above-mentioned purpose of the present invention, the present invention provides a dry wear-resistant seal, including a shaft sle...
