Solve the turbine bearing oil leakage
(1)   Fixed parts of the seal wool felt circle and the journal of the moving parts of the junction is easy to form a gap, so that oil gap can be drilled to the formation of oil spills. Wool felt circle bearings at both ends of the cover seal has a sealing elastic, high-speed rotation of the spindle, the greater flexibility of seal wool felt circle seal, the higher the temperature generated by friction with the spindle, the more likely to make felted wool circles aging and loss of elasticity. Unit in operation, the spindle has a certain swing amount, so the loss of elasticity of wool felt circle with the journal to form a fixed gap, without loss of elasticity or complete loss of elasticity of wool felt circle with the journal will form transient gap , so that oil gap can be drilled. This is the leakage exists or not, and a difference in the extent of an important reason for the gap amount executions to the axis of the swing amount.

(2) the existence of oil spills: oil spill a major source of high-speed movement of the lubricant in the bearing body in the air to drive the air into the oil and oil bubbles formed, and the elevation of the oil bubble beyond the gap can stick the gap elevation (unit operation to the maximum allowed oil level design bearings at both ends of wool felt covered under the ring).

The secondary source of oil spills are small thrust plate at the discharge of oil spray arc, just landed near the spindle seals the spindle neck, and, in fact, is also a radial thrust bearing than the radial bearing lubricants, oil bubble storey much, and the thrust plate discharges of oil, namely, radial thrust bearing and the difference between radial bearings radial thrust bearing there is a spill the source. This is the fundamental causes of the leakage of the radial thrust bearing.
The formation of the oil bubble technology solve the leakage
According to the above theory with the facts of the oil spill causes of the comparative analysis, I think: as long as the bearing lubricating oil does not solve the formation of oil bubbles to eliminate the source of the oil spill, completely avoidable spill than the fixed parts and moving parts The seal does not produce oil spill clearance easy and reliable solution to the bearing oil spill.
