German araymond seals, araymond models, araymond prices

araymond seals refer to devices that prevent fluid leakage, formed by at least one pair of end faces perpendicular to the rotation axis maintaining contact and sliding relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, in conjunction with auxiliary seals. When the auxiliary seal of the compensation ring is a metal bellows, it is called a bellows mechanical seal. There are mainly the following four types of components: a. Primary sealing elements: rotating ring and stationary ring. b. Auxiliary sealing elements: O-rings. c. Clamping elements: springs, thrust rings. d. Drive elements: spring seats and keys or fixing screws.

araymond 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 seals have been pre-tested; 4) During installation, only the seal cover bolts need to be tightened, making it easy to ensure assembly quality; 5) Protects the sealing surfaces 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.

araymond seal startup preparation

1) Thoroughly inspect the mechanical seal, as well as the auxiliary devices and piping, to ensure they are fully installed and comply with technical requirements. 2) Perform a static pressure test on the mechanical seal before startup to check for leaks. If significant leakage is observed, identify the cause and take measures to eliminate it. If this proves ineffective, disassemble the seal for inspection and reinstall it. The static pressure test pressure is generally 2~3 kg/cm². 3) Rotate the pump manually in its direction of rotation to check for smooth and uniform movement. If rotation is difficult or stuck, check whether the assembly dimensions are incorrect and whether the installation is reasonable.

araymond seal precautions

1) Before designing grooves, please carefully read the product descriptions for each series to distinguish whether the product uses an integral groove or a split groove; during the seal installation process, avoid sharp edges; installing rod seals into integral grooves 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 instructions, diagrams, and dimension tables. 2) Before installing the seal, ensure that there are no impurities or cracks in the seal groove; apply operating oil to both the seal groove and the seal surface; install the seal gradually in sequence; 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.
