German EA END-Armaturen seals, EA END-Armaturen models, EA END-Armaturen prices

EA END-Armaturen seals are sealing devices designed to prevent leakage between the pump shaft and the housing. Common types of shaft seals include packing seals, mechanical seals, and power 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 consist of packing seals, mechanical seals, and power seals.

EA END-Armaturen seal principle

Since there is an oil film controlled by the oil seal lip edge between the oil seal and the shaft, this oil film has fluid lubrication characteristics. Under the action of liquid surface tension, the stiffness of the oil film causes the end in contact with air to form a meniscus, preventing the leakage of the working medium and thereby achieving sealing of the rotating shaft. The sealing capability of the oil seal depends on the thickness of the oil film on the sealing surface; if the thickness is too great, the oil seal will leak; if the thickness is too small, dry friction may occur, causing wear on the oil seal and shaft; if there is no oil film between the sealing lip and the shaft, it is easy to cause heating and wear. Therefore, during installation, some oil must be applied to the sealing ring, and it must be ensured that the skeleton oil seal is perpendicular to the shaft axis. If it is not perpendicular, the sealing lip of the oil seal will wipe the lubricating oil off the shaft, which will also lead to excessive wear of the sealing lip. During operation, it is ideal for a small amount of lubricant in the housing to seep out slightly to achieve the state of forming an oil film at the sealing surface.

EA END-Armaturen seal function

The general function of a skeleton oil seal is to isolate the components requiring lubrication in the transmission parts from the output parts, preventing lubricating oil from leaking. It is typically used on rotating shafts and is a type of rotating shaft lip seal. The skeleton acts like reinforcing steel in concrete components, providing reinforcement and allowing the oil seal to maintain its shape and tension. According to the skeleton type, it can be divided into inner skeleton oil seals, outer skeleton oil seals, and exposed inner and outer skeleton oil seals. Skeleton oil seals are made of high-quality nitrile rubber and steel plates, offering stable quality and long service life. They are widely used in automobiles, motorcycle crankshafts, camshafts, differentials, shock absorbers, engines, axles, front and rear wheels, and other parts. 1) Prevent sand, dust, water vapor, etc., from entering the bearing from the outside; 2) Restrict the leakage of lubricating oil from the bearing. The requirements for oil seals are that the dimensions (inner diameter, outer diameter, and thickness) must comply with regulations; they must have appropriate elasticity to properly grip the shaft and achieve a sealing effect; they must be heat-resistant, wear-resistant, strong, resistant to media (oil or water, etc.), and have a long service life.

EA END-Armaturen seal precautions

1) Before designing the groove, please carefully read the product descriptions for each series to distinguish whether the product uses an integral groove or a split groove; during the installation of the seal, avoid sharp edges, and installing bore seals into an integral groove requires the use of installation tools; designers must consider parameters such as groove dimensional accuracy, surface roughness, and extrusion gap. For details, please refer to the product usage instructions, diagrams, and dimension tables. 2) Before installing the seal, ensure that there are no impurities or cracks in the sealing groove, and apply operating oil to the sealing groove and the seal surface respectively; install the seals gradually in order; avoid sharp edges during installation, align the seal properly, and avoid twisting and skewing; if it is a split groove, tighten the pressure cover last.
