Germany tuenkers seals tuenkers model tuenkers price

tuenkers seals can be divided into two major categories: static seals and dynamic seals. Static seals mainly include three types: gasket seals, sealant seals, and direct contact seals. According to working pressure, static seals can be further divided into medium-to-low pressure static seals and high-pressure static seals. Medium-to-low pressure static seals commonly use gasket seals made of softer materials with wider widths, while high-pressure static seals use metal gaskets made of harder materials with very narrow contact widths. Dynamic seals can be divided into two basic types: rotary seals and reciprocating seals. Additionally, depending on whether the sealing element contacts the components moving relative to it, they can be classified as contact seals and non-contact seals; based on the sealing element and contact position, they can be divided into circumferential seals and face seals, with face seals also known as mechanical seals. Centrifugal seals and spiral seals in dynamic sealing achieve sealing by imparting power to the medium during machine operation, hence they are sometimes referred to as power seals.

tuenkers seal construction

The skeleton oil seal structure consists of three parts: the seal body, the reinforcing skeleton, and the self-tightening helical spring. The seal body is divided into the bottom, waist, cutting edge, and sealing lip according to different parts. Typically, in the free state, the inner diameter of the skeleton oil seal is smaller than the shaft diameter, meaning it has a certain "interference fit." Therefore, after the oil seal is installed in the seal housing and on the shaft, the pressure from the oil seal cutting edge and the contraction force of the self-tightening helical spring generate a certain radial clamping force on the shaft. After a period of operation, this pressure will rapidly decrease or even disappear, so the spring can continuously compensate for the self-tightening force of the oil seal.

tuenkers seal usage guide

1) When the gearbox lubricating oil volume is ≤7 liters, the addition amount per liter of lubricating oil is 20‐30ml; 2) 7‐15 liters, the addition amount is 15‐20ml per liter of lubricating oil; 3) >15 liters, the addition amount is 10ml per liter of lubricating oil; 4) Oil seals not in temporary use should be properly stored to prevent contamination with oil, dust, or exposure to sunlight. 5) When the shaft diameter wears into a "V" shaped groove, causing the new oil seal lip contact pressure with the shaft to drop and fail to seal oil, the displacement method can be used to compensate.

tuenkers seal installation and shutdown

1) Before starting, ensure the seal chamber is filled with liquid. For media that solidify, use steam to heat the seal chamber to melt the medium. Manual rotation must be performed before starting to prevent sudden startup from causing the soft ring to shatter. 2) For mechanical seals using an external pump seal oil system, start the seal oil system first. Stop the seal oil system last after shutdown. 3) 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.
