Abstract

An apparatus and method to enhance the overall performance of mechanical seals in one of the following ways: by reducing seal face wear, by reducing the contact surface temperature, or by increasing the life span of mechanical seals. The apparatus is a mechanical seal (e.g., single mechanical seals, double mechanical seals, tandem mechanical seals, bellows, pusher mechanical seals, and all types of rotating and reciprocating machines) comprising a rotating ring and a double-tier mating ring. In a preferred embodiment, the double-tier mating ring comprises a first and a second stationary ring that together form an agitation-inducing, guided flow channel to allow for the removal of heat generated at the seal face of the mating ring by channeling a coolant entering the mating ring to a position adjacent to and in close proximity with the interior surface area of the seal face of the mating ring.

Mechanical seal having a single-piece, perforated mating ring

Patent Khonsari, Michael; Somanchi, Anoop

A mechanical seal (e.g., single mechanical seals, double mechanical seals, tandem mechanical seals, bellows, pusher mechanical seals, and all types of rotating and reciprocating machines) with reduced contact surface temperature, reduced contact surface wear, or increased life span. The mechanical seal comprises a rotating ring and a single-piece, perforated mating ring, which improves heat transfer by controllably channeling coolant flow through the single-piece mating ring such that the coolant is in substantially uniform thermal contact with a substantial portion of the interior surface area of the seal face, while maintaining the structural integrity of the mechanical seal and minimizing themore »« less

Mechanical seal with textured sidewall

Patent Khonsari, Michael; Xiao, Nian

The present invention discloses a mating ring, a primary ring, and associated mechanical seal having superior heat transfer and wear characteristics. According to an exemplary embodiment of the present invention, one or more dimples are formed onto the cylindrical outer surface of a mating ring sidewall and/or a primary ring sidewall. A stationary mating ring for a mechanical seal assembly is disclosed. Such a mating ring comprises an annular body having a central axis and a sealing face, wherein a plurality of dimples are formed into the outer circumferential surface of the annular body such that the exposed circumferential surfacemore »« less

Magnetic shaft seals prevent hazardous leakage from wastewater agitators

Journal Article Traino, F - Chem. Process. (Chicago); (United States)

The US Department of Energy's laboratory in Miamisburg, OH, operated by Monsanto Research Corporation, processes approximately 45,000 gallons per week of low-level radioactive wastewater to meet Federal Environmental Protection Agency quality standards. Preventing the spread of radioactive contamination throughout the operating area demands effective sealing of all process piping, valves, pumps, and agitators. Rotating shafts of pumps and agitators installed a the start of operations in 1947 were sealed by stuffing glands with graphite impregnated asbestos packing. These pumps proved to be unsatisfactory. In the mid-1970's, new process pumps with mechanical seals and some with magnetic drives were installed. Later,more »« less
GRAPHITE SEALS FOR ROTATING SHAFTS

Journal Article Plutalova, L - Vestnik Mashinostroyeniya

When rubber and other soft seais are inapplicable, especially in the presence of corrosive fluids, polytetrafluorethylene ( fluon'') seals are sometimes used. Its low heat conduction restricts its use to low speeds, pressures and temperatures and the presence of liquid in the clearance. In many critical applications graphite seals are used. The manufacture, advantages, and drawbacks of graphite are discussed. Only two basic types of graphite are made in the Soviet Union compared with dozens of variants in the U.S.A. One type is stronger but less heat-conductive than the second type. Their permissible pressures are 35 and 25 kg/cmu andmore »« less
Development of high temperature, high pressure rotating shaft seals: Final report

Technical Report Heshmat, H.; Shapiro, W.

Rotating shaft seals used in coal gasification equipment are exposed to difficult environmental conditions including temperature from 430/sup 0/C to 816/sup 0/C (800/sup 0/F to 1500/sup 0/F), high pressure (to 10 MPa or 1500 psig), and high levels of particulate contamination (50,000 to 100,000 ppM). The program reported upon was designed to develop long-life seals that would not require external flushing or cooling. The approach taken was to develop unbalanced face that would remain closed and prevent particulate entry into the interface. Wear resistant materials and coatings with low friction coefficients are required. Significant results of the program are enumerated:more »« less
