Large vertical pump oil bearing water bearing instead
Most favorable price : sales@hellerbearings.com
Vertical pump unit, due to the structure, manufacture, installation error, to flow and so on various aspects reason, main shaft and the impeller by the radial force, runtime pump guide bearing plays a stable the role of pump shaft and impeller. Guide bearing early adoption of rubber material, the water lubrication. With the large-scale development of the pump, the rotating part of unbalanced radial force is growing, although later adopted the better wear resistance of polyurethane and other materials, and USES the clear water lubrication, but the result is bad, bearing material easy to wear, the river water quality is poor when life is only hundreds of hours. Inspection found that is worn bearing wall is embedded with a large number of grains of sand, water device sealing effect is bad, in the river sediment will enter the bearing. So, then widely used in large vertical pump oil lubrication babbitt guide bearing, increase the bearing anti-wear ability. But oil bearing structure complex, high cost and the fatal weakness is below the water sealing device is unreliable, often failure of leaking, and the bearing of flooding damage. Considering the water lubrication guide bearing, as long as the guarantee in the river sediment is not enter, its operation could significantly longer service life. Analyze the problem, and its structure was improved, the oil bearing, bearing water.
