The oil seal of the steam driven feedwater pump is an important component that ensures the separation of the oil system and the water system, preventing lubricating oil from leaking into the working medium of the pump and preventing the working medium from entering the oil system. In a steam driven feedwater pump, the oil seal is usually located at the bearing, which is a key component supporting the rotation of the rotor and requires lubricating oil to reduce wear and heat dissipation.
When installing oil seals, it is necessary to ensure the accuracy of the fit between the oil seal and the shaft or bearing, as well as the sealing performance between the oil seal and the oil seal seat. The function of the oil seal spring is to provide sufficient pressure to ensure close contact between the oil seal and the shaft or bearing, thereby achieving a good sealing effect.
To ensure the performance and lifespan of the oil seal, it is necessary to regularly maintain and inspect it. This includes checking the wear of the oil seal, the pressure of the spring, and the sealing performance of the oil seal seat. If the oil seal is found to be damaged or severely worn, it should be replaced in a timely manner.
During the operation of the steam driven feedwater pump, attention should also be paid to the cooling and heat dissipation of the oil seal. Because the oil seal generates heat during rotation, if the heat cannot be dissipated in time, it may cause softening or damage to the oil seal material. Therefore, a cooling system is usually installed near the oil seal to maintain the working temperature of the oil seal within an appropriate range.
