German elbe dichtungen seals elbe dichtungen models elbe dichtungen prices

elbe dichtungen seals are a type of friction seal or stuffing box used to prevent liquid leakage between the shaft and bearings of compressors or other fluid handling equipment. They are also sealing devices designed to prevent leakage at the pump shaft and housing. Common types of shaft seals include packing seals, mechanical seals, and power seals. The shaft seal of a reciprocating pump is typically a packing seal. When transporting media where leakage is not permitted, diaphragm reciprocating pumps can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly consist of packing seals, mechanical seals, and power seals.

elbe dichtungen 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 different parts such as the bottom, waist, cutting edge, and sealing lip. Typically, in its free state, the inner diameter of the skeleton oil seal is smaller than the shaft diameter, meaning it has a certain amount of "interference fit." Therefore, after the oil seal is installed on the seal seat and shaft, the pressure from the oil seal's cutting edge and the contraction force of the self-tightening helical spring exert a radial clamping force on the shaft. After some time of operation, this pressure will quickly decrease or even disappear, so the spring can continuously compensate for the self-tightening force of the oil seal.

elbe dichtungen seal usage guide

1) When the gearbox lubricating oil volume is ≤7 liters, the additive amount per liter of lubricating oil is 20‐30ml; 2) 7‐15 liters, the additive amount per liter of lubricating oil is 15‐20ml; 3) >15 liters, the additive amount per liter of lubricating oil is 10ml; 4) Unused oil seals should be stored properly 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 issue can be remedied by shifting the position.

elbe dichtungen seal maintenance

1) Control of shaft seal pressure: High shaft seal pressure can cause steam to escape from the shaft seal, leading to water ingress into the oil and deteriorating turbine oil quality. Excessively high shaft seal pressure may trigger the safety valve of the equalizing tank, wasting working medium and damaging equipment. Low shaft seal pressure may cause a drop in unit vacuum, allowing cold air to enter the shaft seal or even the cylinder, resulting in cooling of the shaft seal section or inside the cylinder, seriously threatening equipment safety. 2) Impact of abnormal shaft seal temperature on the unit: When the shaft seal temperature is too high, especially before starting the unit, excessive heat can cause intense heating at the shaft end gland and rotor gland sections, leading to localized stress concentration and deformation. This may alter the gap between the rotor and cylinder, increasing shaft seal steam leakage and differential expansion, potentially causing dynamic and static friction. When the shaft seal temperature is too low, the shaft end gland and rotor gland sections are cooled, similarly causing localized stress concentration, altering the gap between the cylinder and rotor, increasing shaft end leakage, and reducing differential expansion. Additionally, excessively low shaft seal temperatures may result in water-carrying steam in the shaft seal supply, causing water hammer in the supply pipeline. In severe cases, this can lead to water ingress into the turbine.
