Measures for extending the lifespan of screw pumps (extending the lifespan of underwater bearings)
By measuring the moisture content of the grease, we can manage the wear condition more precisely!
Water and sand are entering the sliding parts from the oil seal area, accelerating wear, which increases the gap between the sleeve and the metal, leading to issues such as contact with the impeller and potential failures. Since it is underwater and requires open inspection, which incurs costs, it is not easily noticed. However, this can be resolved by implementing a structure called the "Underwater Bearing Sliding Part Wear Detection System," which allows maintenance from land. By measuring the water content in the grease, the degree of wear can be managed more precisely. 【Features】 - By providing a grease return piping on the primary side of the oil seal, the sealing performance lasts for about four years. - A system has been established that allows for the detection of wear from land through the observation of returning grease. → Underwater Bearing Sliding Part Wear Detection System - The measurement of water content in the grease allows for more detailed management of wear. *For more details, please refer to the PDF document or feel free to contact us.
