German bormann neupert seals, bormann neupert models, bormann neupert prices

bormann neupert seals are a common term for general seals, simply referring to lubricating oil seals. They are mechanical components used to seal grease (oil is the most common liquid in transmission systems, and also refers to general liquids). They isolate lubricated parts in the transmission from 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 oil seals commonly referred to are usually this type of tc skeleton oil seal.

Introduction to bormann neupert seals

A mechanical seal is a shaft sealing device for rotating machinery, such as centrifugal pumps, centrifuges, reaction vessels, and compressors. Since the drive shaft passes through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment. The medium in the equipment leaks outward through this gap. If the pressure inside the equipment is lower than atmospheric pressure, air leaks into the equipment. Therefore, a shaft sealing device is required to prevent leakage. There are many types of shaft seals. Due to advantages such as low leakage and long service life, mechanical seals are the primary shaft sealing method for these equipment worldwide. Mechanical seals are also known as face seals. National standards define them as: "A device that prevents fluid leakage, formed by at least one pair of faces perpendicular to the rotation axis, which maintain contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of a compensation mechanism, along with auxiliary seals."

Structure and composition of bormann neupert seals

1) Main components: rotating ring, stationary ring, cooling device, and compression spring (depending on the specific equipment). 2) Auxiliary seals: O-rings (including O-shape, X-shape, U-type, wedge shape, rectangular flexible graphite, PTFE-covered rubber O rings, etc.). 3) Elastic compensation mechanism: springs, thrust rings, spring seats, keys, or various screws. 4) Classification: single-face, double-face; balanced, unbalanced; arbitrary rotation direction, fixed rotation direction.

Installation precautions for bormann neupert seals

1) During installation, pay close attention to avoid installation deviations. Tighten the pressure cover after aligning the coupling. Bolts should be tightened evenly to prevent tilting of the pressure cover face. Check all points with a feeler gauge; the error must not exceed 0.05 mm. Check the fit clearance (i.e., concentricity) between the pressure cover and the outer diameter of the shaft or shaft sleeve. It must be uniform around the circumference. Check all points with a feeler gauge; the allowable error must not exceed 0.01 mm. 2) Compress the spring according to regulations. Excessive or insufficient compression is not allowed. The required error is 2.00 mm. Excessive compression increases the specific face pressure, accelerating face wear. Insufficient compression results in inadequate specific pressure, failing to achieve sealing. 3) After installing the rotating ring, it should automatically spring back when pressed against the spring. 4) Installation position requirements: To ensure stable operation, long service life, and low leakage performance of the mechanical seal, correct installation on the machine is crucial. When installing the mechanical seal on the machine, compare it carefully with the general assembly drawing before installation to confirm that all parts are ready. Pay attention to any abnormalities such as scratches or damage on the sealing friction faces and O-rings. Also check for scratches on the surfaces of the shaft or shaft sleeve in contact with packing and O-rings (O rings), as well as on flanges and other components. If any abnormalities are found, replace or repair before use. During actual installation, do not bring more parts than needed to the site. If parts remain after installation, it indicates missing installations. If parts are insufficient, it means parts were assembled in unnecessary places, serving as a self-check during installation.
