German techagum seals techagum models techagum prices

techagum seals are sealing devices installed to prevent leakage between the pump shaft and the housing. Common shaft seal types include packing seals, mechanical seals, and dynamic seals. The shaft seal of a reciprocating pump is usually a packing seal. When transporting media where leakage is not permitted, a diaphragm reciprocating pump can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly include packing seals, mechanical seals, and dynamic seals.

techagum seal principle

A mechanical seal is a shaft sealing device that achieves leak prevention by keeping one or several pairs of end faces, which slide relative to each other perpendicular to the axis, in contact under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, supplemented by auxiliary seals. A common mechanical seal structure consists of components such as the stationary ring (static ring), rotating ring (dynamic ring), elastic element spring seat, set screws, rotating ring auxiliary O-ring, and stationary ring auxiliary O-ring. Anti-rotation pins are fixed to the gland to prevent the stationary ring from rotating. The rotating ring and stationary ring can also be referred to as compensation rings or non-compensation rings, depending on whether they have axial compensation capability.

techagum seal system composition

1) Seal chamber: In the past, seal chambers housing mechanical seals were stuffing boxes designed for soft packing seals. They are unsuitable for housing mechanical seals, not only because the dimensions are too small and the clearances too narrow, but also because the simple cylindrical shape is inappropriate. Standards for enlarged mechanical seal chambers have been established abroad. In addition, Durametallic Corporation in the United States and the Fluid Engineering Study Group in the United Kingdom are both researching reasonable mechanical seal chamber designs. Their shapes should not only facilitate fluid flow and heat dissipation but also help remove solid particles, creating a favorable environment for the seal. 2) Volatile organic compound (VOC) emission control system: In the past, attention was focused only on eliminating visible fluid leaks, while invisible VOC emissions were neglected, resulting in environmental pollution and posing risks to equipment and personnel. Organizations abroad, such as the Sealing Technology Committee of the Society of Tribologists and Lubrication Engineers (STLE) in the United States, have developed guidelines for controlling volatile emissions in rotating machinery, compressors, and screw systems with mechanical seals, including SP-30 (1994), SP-32 (1990), and SP-33 (1991). SP-30 is implemented in three stages. It clearly defines barrier fluids and buffer fluids, clarifying erroneous and confusing concepts. A barrier fluid is introduced between dual seals to completely block process fluid from leaking into the surrounding environment. The pressure of the barrier fluid is always higher than the pressure of the sealed process fluid. A buffer fluid is used between dual seals as a lubricant or buffer, and its pressure is always lower than the pressure of the sealed process fluid. 3) Auxiliary system integration: Mechanical seal auxiliary systems require integration of cooling, heating, and flushing systems. Pump circulation needs optimization, and issues such as condition monitoring systems are being studied and resolved. The integration of auxiliary systems is specified in the API-682 standard. 4) Gas barrier seal system: In the past, liquid-blocking-liquid or liquid-blocking-gas configurations were commonly used in barrier seal systems. To simplify bulky barrier liquid systems, barrier gases are now used to block liquids or gases. In gas-blocking seal systems, spiral groove gas seals with barrier gas, floating bushings with barrier gas, and other methods can be employed to block gases and liquids.

techagum seal precautions

1) Obtain a fixed quantity of oil seals. 2) From receipt to assembly, oil seals must be kept clean. 3) Before assembly, inspect the oil seals. Measure all dimensions of the framed oil seal to ensure they match the shaft and housing dimensions. Before installing the framed oil seal, clearly compare the shaft diameter with the inner diameter of the oil seal; they must match. The internal dimensions of the housing must be suitable for the outer diameter width of the oil seal. Check whether the lip of the framed oil seal is damaged or deformed, and whether the spring has fallen off or rusted. Prevent the oil seal from being stored flat during transportation, as external squeezing and impact can affect its roundness. 4) Perform machining inspection procedures before assembly. Measure whether the dimensions of the housing and shaft are correct, especially the internal chamfer, which must not have a slope. The end faces of the shaft and housing must be machined smoothly. Chamfers must be free of damage and burrs. Clean the assembly area. There must be no burrs, sand, iron chips, or other debris at the shaft insertion point (chamfer), as these can cause irregular damage to the oil seal lip. It is recommended to use an r angle for the chamfer. 5) Regarding operational technique, use your hands to feel whether the surface is smooth and truly round. 6) Do not tear open the packaging paper of the framed oil seal too early before installation to prevent debris from adhering to the seal surface and entering the working environment. 7) Before installation, apply an appropriate amount of lithium-based grease containing molybdenum disulfide between the lips of the framed oil seal. This prevents dry grinding of the lip during instantaneous shaft startup, which affects the lip's interference fit, and ensures prompt assembly. If the oil seal housing with the installed seal is not immediately mounted, cover it with a cloth to prevent foreign matter from adhering to the seal. Hands or tools applying lithium grease must be clean. 8) Framed oil seals must be installed flat, without tilting. It is recommended to use hydraulic equipment or sleeve tools for installation. Do not apply excessive pressure; the speed must be uniform and slow. 9) Mark the machine on which this batch of framed oil seals is installed for tracking purposes, and carefully monitor the entire process.
