Germany industriefabrik seals industriefabrik model industriefabrik price

industriefabrik seals are a typical representative of oil seals; the term "oil seal" generally refers to skeleton oil seals. The function of an oil seal is generally to isolate components requiring lubrication in transmission parts from the external environment, preventing lubricating oil leakage. The skeleton acts like reinforcing steel in concrete components, providing reinforcement and enabling the oil seal to maintain its shape and tension. According to structural form, they can be divided into single-lip skeleton oil seals and double-lip skeleton oil seals. The secondary lip of a double-lip skeleton oil seal serves a dust-proof function, preventing external dust, impurities, etc., from entering the machine interior. According to skeleton type, they can be divided into inner-covered skeleton oil seals, exposed skeleton oil seals, and assembled oil seals. According to operating conditions, they can be divided into rotating skeleton oil seals and reciprocating skeleton oil seals. Used for gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles, and other parts.

industriefabrik seal features

1) No need to measure the seal working length during installation; 2) The shaft can be adjusted at any time; 3) No leakage occurs at startup because the seal has been pre-tested; 4) During installation, only the clamping seal cover bolts need to be fitted, making assembly quality easy to ensure; 5) Protects the sealing surface from contamination by debris or damage due to operational errors before installation or startup; 6) Can be readjusted after thermal expansion of the machinery; 7) Self-centering through fit; 8) Seals can be easily removed for cleaning and inspection without disassembling the pump equipment. The API682 standard recommends the use of cartridge mechanical seals for all mechanical seals.

industriefabrik seal startup preparation

1) Comprehensively check whether the mechanical seal, auxiliary devices, and pipeline installations are complete and comply with technical requirements. 2) Perform a static pressure test before starting the mechanical seal to check for leakage. If there is significant leakage, identify the cause and eliminate it. If still ineffective, disassemble for inspection and reinstall. Generally, the static test pressure is 2~3 kg/cm². 3) Rotate the pump according to its direction of rotation to check if it moves lightly and evenly. If rotation is difficult or stuck, check whether assembly dimensions are incorrect or installation is unreasonable.

industriefabrik seal precautions

1) Obtain a fixed quantity of oil seals. 2) Keep clean from receipt of the oil seal to assembly. 3) Before assembly, inspect the oil seal; measure whether the dimensions of each part of the skeleton oil seal match the shaft and housing dimensions. Before installing the skeleton oil seal, clearly compare the shaft diameter with the inner diameter of the oil seal to ensure they match. The internal dimensions of the housing must suit the outer diameter width of the oil seal. Check whether the lip of the skeleton oil seal is damaged or deformed, and whether the spring has fallen off or rusted. Prevent the oil seal from being stored flat during transport, subjected to external squeezing and impact, which could destroy its roundness. 4) Perform machining inspection procedures before assembly; measure whether the dimensions of the housing and shaft parts are correct, especially the inner chamfer, which must not have a slope. The end face machining of the shaft and housing must be smooth; chamfers must have no damage or burrs. Clean the assembly area; there must be no burrs, sand, iron chips, or other debris at the shaft insertion point (chamfer), as these will cause irregular damage to the oil seal lip. It is recommended to use a r angle for the chamfer. 5) Regarding operational technique, use your hand to feel whether it is smooth and truly round. 6) Do not tear open the packaging paper of the skeleton oil seal too early before installation to prevent debris from adhering to the seal surface and entering into operation. 7) Before mounting, apply an appropriate amount of lithium-based grease with molybdenum disulfide between the lips of the skeleton oil seal to prevent dry grinding of the lip during instantaneous shaft startup, which affects the lip interference fit, and assemble as soon as possible. If the oil seal seat with the installed seal is not immediately mounted, it is recommended to cover it with a cloth to prevent foreign matter from adhering to the seal. Hands or tools applying lithium grease must be clean. 8) Skeleton oil seals must be installed flat, without tilting. It is recommended to use hydraulic equipment or sleeve tools for installation. Pressure should not be too high; speed must be uniform and slow. 9) Mark the machine where this skeleton oil seal is installed for tracking purposes, and pay close attention to the entire process.
