German hug technik seals, hug technik models, hug technik prices

hug technik seals are devices that prevent fluid leakage, consisting of at least one pair of end faces perpendicular to the axis of rotation. These faces remain in contact and slide relative to each other under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, along with the assistance of auxiliary seals. Mechanical seals where the elastic loading mechanism and auxiliary seal are metal bellows are referred to as metal bellows seals. In light-duty seals, rubber bellows are sometimes used as auxiliary seals; however, since the elastic force of rubber bellows is limited, springs are generally required to supplement the loading force. Mechanical seals are commonly abbreviated as "mechanical seals".

Advantages of hug technik seals

1) Oil seals have a simple structure and are easy to manufacture. Simple oil seals can be molded in a single step, and even the most complex oil seals do not require complicated manufacturing processes. Metal-cased oil seals only require processes such as stamping, bonding, insertion, and molding to combine metal and rubber into the required oil seal. 2) Oil seals are lightweight and consume less material. Each oil seal is a combination of thin-walled metal and rubber components, resulting in minimal material consumption and very light weight for each seal. 3) Oil seals require small installation spaces and have small axial dimensions, making them easy to machine and allowing for compact machine design. 4) Oil seals offer good sealing performance and long service life. They have a certain degree of adaptability to machine vibration and spindle eccentricity. 5) Oil seals are easy to disassemble and convenient to inspect. 6) Oil seals are inexpensive.

Precautions for hug technik seals

1) Preparation and precautions before startup: a, comprehensively check whether the mechanical seal, auxiliary devices, and piping are fully installed and comply with technical requirements. b, perform a static pressure test on the mechanical seal before startup to check for leakage. If there is significant leakage, identify the cause and take measures to eliminate it. If this is ineffective, disassemble, inspect, and reinstall. The static test pressure is generally 2~3 kg/cm². c, manually rotate the pump according to its rotation direction to check if it moves lightly and smoothly. If rotation is difficult or stuck, check for errors in assembly dimensions and whether the installation is reasonable. 2) Installation and shutdown: a, keep the seal chamber filled with liquid before startup. When conveying media that solidify, use steam to heat the seal chamber to melt the media. Manual rotation must be performed before startup to prevent sudden startup from causing fracture of the soft ring. b, for mechanical seals using an external seal oil system, start the seal oil system first. Stop the seal oil system last after shutdown. c, do not immediately stop the cooling water for the seal oil chamber and face seal after stopping a hot oil pump; wait until the oil temperature at the face seal drops below 80 degrees before stopping the cooling water to avoid damaging seal components. 3) Operation: a, if slight leakage occurs after pump startup, observe for a period. If the leakage does not decrease after continuous operation for 4 hours, stop the pump for inspection. b, the pump operating pressure should be stable, with pressure fluctuations not exceeding 1 kg/cm². c, avoid cavitation during pump operation to prevent dry friction and damage to the sealing surfaces. d, regularly check the sealing condition. During operation, if leakage exceeds the standard (no more than 5 drops/min for heavy oil, no more than 10/min for light oil), and there is no improvement trend within 2-3 days, stop the pump to inspect the sealing device.

Causes of failure in hug technik seals

Failures in mechanical seals are generally identified only after phenomena such as abnormal leakage, abnormal wear, or abnormal torque occur. The causes of failure can be broadly categorized into the following four aspects: 1) Incorrect design or selection of the mechanical seal; 2) Poor quality of the mechanical seal; 3) The precision of the machine using or installing the mechanical seal does not meet requirements; 4) Errors in machine operation.
