Germany gmt seals gmt model gmt price

gmt seals are devices that prevent fluid leakage, consisting of at least one pair of faces perpendicular to the axis of rotation that 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, together with 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 also used as auxiliary seals; since the elastic force of rubber bellows is limited, springs are generally required to supplement the loading force. Mechanical seals are commonly abbreviated as "mech seals".

gmt 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 sections such as the bottom, waist, cutting edge, and sealing lip. Typically, in its free state, the inner diameter of a 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 seal lip and the contraction force of the self-tightening helical spring exert a certain radial tightening force on the shaft. After a period of operation, this pressure will rapidly decrease or even disappear; thus, the spring can compensate for the self-tightening force of the oil seal at any time.

gmt seal usage instructions

1) When the gearbox lubricating oil volume is ≤7 liters, the additive amount per liter of lubricating oil is 20‐30ml; 2) When 7‐15 liters, the additive amount is 15‐20ml per liter of lubricating oil; 3) When >15 liters, the additive amount is 10ml per liter of lubricating oil; 4) Oil seals not in immediate use should be stored properly to prevent contamination with oil, dust, or exposure to direct sunlight. 5) When the shaft diameter wears into a "V" shaped groove, causing the contact pressure between the new oil seal lip and the shaft to drop so that it can no longer seal oil, the displacement method can be used to compensate.

gmt seal failure causes

Mechanical seal failures are generally only identified after phenomena such as abnormal leakage, abnormal wear, or abnormal torque appear. 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) Incorrect machine operation.
