Abstract
The utility model discloses a double-seal mechanical sealing assembly, which comprises a shaft, a pump shell, a movable ring base, movable sealing rings, a hard alloy ring, a static ring sealing element, static sealing rings, a sealing cover, an O-shaped ring and a spring, wherein the two ends of the sealing assembly respectively are respectively sealed by the movable sealing rings and the static sealing rings, and the sealing assembly is made of wear-resisting hard alloy. According to the utility model, as the two ends of the sealing assembly are respectively sealed by the movable ring and static ring sealing system, in working, the inner pressure generated by the movement of the shaft at high speed can not cause inner leakage and outer leakage; due to the wear-resisting property of the hard alloy ring, the wear to the sealing assembly can be effectively reduced, and the service life of the whole assembly is improvedprolonged; and as no inner leakage and outer leakage are caused to pollute water, cooling water can be recycled, and the sealing assembly is environment-friendly.
Description
Technical field
The utility model relates to the black box of a kind of seal arrangement of pump with mechanical seal, particularly a kind of pump with mechanical seal.
Background technique
The material that the workshop circulation is carried uses mechanical seal, and cooling water is taken away heat by mechanical seal die cavity cooling and lubricating, and outside framework oil seal is used at sealing water position, because the two-stage electric motor rotating speed is very fast, outside framework oil seal weares and teares easily, causes leaking frequently, and the processing with environment-protective water is produced in impact.
Summary of the invention
The purpose of this utility model is: for the problem of above-mentioned existence, provide a kind of mechanical sealing assembly of dynamic and static ring double-sealing.
The technical solution adopted in the utility model is:
A kind of mechanical sealing assembly comprises axle, pump case, rotating seat, rotary packing ring, carbide ring, stationary ring Sealing, stationary seal ring, sealing cover, O type circle, spring.
Described assembly is a bilateral symmetry type assembly, and sealing cover is fixed by the two ends of bolt and pump case, cavity of inner formation; Mesopore is stamped in sealing, and axle passes pump case by the mesopore of sealing cover, and is coaxial with pump case;
The position of sealing cover vertically, stationary seal ring is enclosed within on the axle outward, the stationary ring Sealing is enclosed within on the stationary seal ring outward, the stationary ring Sealing is rubber parts, stationary seal ring is step ladder circular ring, rotary packing ring links to each other with stationary seal ring by carbide ring, and carbide ring is embedded in the rotary packing ring, is coated on the axle, rotary packing ring is the cylindrical body ring part, there is a projection position at the close carbide ring of inwall, is used for the assembling carbide ring, and rotating seat is enclosed within on the axle outward, be enclosed within the rotary packing ring in one end, spring fitting forms a precompressed radially to assembly parts in the telescopic cavity that is formed by rotary packing ring and rotating seat, strengthen sealability.Projection is arranged in the middle of the rotating seat.
All parts are installed in the cavity that is formed by pump case and sealing cover, and arrange with the Central Symmetry of rotating seat, thereby form the mechanical sealing assembly of two ends double-sealing.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, because the dynamic and static ring sealing system has all been adopted at two ends, when work, because the high-speed motion of axle, the interior pressure that causes can not cause interior leakage and leak.
2, the antiwear characteristic of carbide ring effectively reduces the wearing and tearing of Sealing, has improved the working life of whole assembly.
3, owing to do not understand interior leakage and leak and cause the pollution of water, cooling water can recycle, environmental protection.
