German teku seals teku models teku prices

teku 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), isolating lubricated parts from output parts in transmission components 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. Generally, when people refer to oil seals, they often mean this type of tc skeleton oil seal.

teku seal features

1) No need to measure the working length of the seal during installation; 2) The shaft can be adjusted at any time; 3) There will be no leakage issues at startup because the seal has been pre-tested; 4) During installation, only the bolts securing the gland need to be tightened, making it easy to ensure assembly quality; 5) Protects the sealing surface from contamination or damage due to operational errors before installation or startup; 6) Can be readjusted after thermal expansion of machinery equipment; 7) Self-centering through fit; 8) Easy to remove the seal for cleaning and inspection without disassembling the pump equipment. All mechanical seals recommended in the API682 standard use cartridge-type mechanical seals.

teku seal startup preparation

1) Conduct a comprehensive inspection of the mechanical seal, as well as auxiliary devices and pipeline installations, to ensure completeness and compliance with technical requirements. 2) Perform a static pressure test on the mechanical seal before starting to check for leaks. If there is significant leakage, identify and eliminate the cause. If ineffective, dismantle and reassemble. Typically, the static pressure test uses 2~3 kg/cm². 3) Rotate the pump according to its direction to check if it moves smoothly and evenly. If rotation is difficult or stuck, inspect whether the assembly dimensions are incorrect or if the installation is unreasonable.

teku seal installation precautions

1) Pay close attention to avoiding installation deviations during installation. Tighten the gland after aligning the coupling, ensuring even tightening of bolts to prevent tilting of the gland face. Use a feeler gauge to check each point, with an error not exceeding 0.05 mm. Check the clearance between the gland and the outer diameter of the shaft or sleeve (i.e., concentricity). Ensure uniformity around all points, with an allowable deviation not exceeding 0.01 mm. 2) Compress the spring according to specifications, avoiding excessive or insufficient compression. The required error should be within 2.00 mm. Excessive compression increases end-face specific pressure, accelerating wear. Insufficient compression results in inadequate specific pressure, failing to achieve proper sealing. 3) After installing the rotating ring, pressing it against the spring should allow it to automatically return. 4) Installation position requirements: To ensure stable operation, long life, and low leakage performance of the mechanical seal, correct installation on the machine is crucial. Before installing the mechanical seal onto the machine, carefully compare it with the overall assembly drawing to confirm that all parts are ready. Pay attention to any abnormalities such as scratches or defects on the sealing surfaces of friction pairs, sealing rings, etc. Also, check for scratches on the shaft or sleeve surfaces, flanges, and other components in contact with packing, sealing rings (O rings), etc. If abnormalities are found, replace or repair them before use. During actual installation, do not bring unnecessary parts to the site. If parts remain after installation, it indicates missing installations; if parts are insufficient, it means unnecessary parts were assembled, serving as a self-check during installation.
