aps seals are the customary term for general seals, simply referring to lubricating oil seals. They are mechanical components used to seal grease (oil is the most common liquid substance in transmission systems, and also refers to general liquid substances), isolating the parts requiring lubrication in the transmission components from the output parts to prevent lubricating oil leakage. Seals used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. The representative form of oil seals is the TC oil seal, which is a double-lip oil seal with a self-tightening spring fully covered by rubber. The term oil seal generally refers to this type of tc skeleton oil seal.

aps seal advantages

1) The oil seal structure is simple and easy to manufacture. Simple oil seals can be molded in one step; even the most complex oil seals do not have complicated manufacturing processes. Metal skeleton oil seals only require processes such as stamping, bonding, inlaying, and molding to combine metal and rubber into the required oil seal. 2) Oil seals are lightweight and consume less material. Each oil seal is a combination of thin-walled metal and rubber parts, consuming very little material, so each oil seal is very light. 3) The installation position of the oil seal is small, the axial dimension is small, it is easy to process, and makes the machine compact. 4) The oil seal has good sealing performance and a long service life. It has certain adaptability to machine vibration and spindle eccentricity. 5) Oil seals are easy to disassemble and convenient to inspect. 6) Oil seals are inexpensive.

aps seal precautions

1) Preparation and precautions before startup: a. Comprehensively check whether the mechanical seal, as well as auxiliary devices and pipeline installations, are complete and meet technical requirements. b. Perform a static pressure test on the mechanical seal before startup to check for leakage. If there is significant leakage, identify the cause and eliminate it. If still ineffective, disassemble, inspect, and reinstall. Generally, the static pressure test pressure is 2~3 kg/cm². c. Rotate the pump according to its direction of rotation to check if it is light and uniform. If rotation is difficult or immobile, check whether the assembly dimensions are incorrect and whether the installation is reasonable. 2) Installation and shutdown: a. Keep the seal chamber filled with liquid before startup. When transporting solidified media, use steam to heat the seal chamber to melt the medium. Manual rotation must be performed before startup to prevent sudden startup from causing the soft ring to shatter. b. For mechanical seals utilizing an external seal oil system, start the seal oil system first. Stop the seal oil system last after shutdown. c. After stopping a hot oil pump, do not immediately stop the cooling water for the seal oil chamber and face seal. Wait until the oil temperature at the face seal drops below 80 degrees before stopping the cooling water to avoid damaging the seal parts. 3) Operation: a. If there is slight leakage after the pump starts, observe for a period of time. If continuous operation for 4 hours does not reduce the leakage, stop the pump for inspection. b. The pump operating pressure should be stable, with pressure fluctuations not exceeding 1 kg/cm². c. During pump operation, avoid cavitation to prevent dry friction of the sealing surfaces and seal damage. d. Frequently check the sealing condition. During operation, if leakage exceeds the standard (not more than 5 drops/min for heavy oil, not more than 10/min for light oil), and there is no improvement trend within 2-3 days, stop the pump to inspect the sealing device.

aps seal functions and applications

Engine: Crankshaft - front and rear crankshaft oil seals; Valve - valve oil seals (engine repair kit o O-rings) (distributor oil seal, water pump oil seal, balance shaft oil seal, oil pump oil seal...); Camshaft - camshaft oil seal; Transmission: Transmission - front and rear transmission oil seals; Shift lever oil seal (transmission repair kit o O-rings) (Transfer case - front and rear transfer case oil seals); Rear axle: Half shaft - rear half shaft oil seal; Differential - (front/rear) pinion oil seal; Rear wheel oil seal; Front wheel oil seal; Steering gear oil seal (steering gear repair kit o O-rings); Power steering booster oil seal (front half shaft oil seal). Oil seals are required wherever there is liquid lubricating oil inside a rotating housing that connects to the exterior. Some are made of rubber, some of metal, but most are steel-reinforced rubber, such as rear crankshaft oil seals, front and rear transmission oil seals, left and right half shaft oil seals, front main reducer oil seals, and air compressor crankshaft oil seals.
