Description
Technical Field
The utility model relates to the technical field of floating ring seal disassembly and replacement of centrifugal compressors, in particular to a multifunctional floating ring seal disassembly device.
Background
The floating ring seal consists of an inner floating ring, an outer floating ring, a floating ring seat, a gland, a spring, an anti-rotation pin, an auxiliary O-shaped ring and the like. After the seal oil is injected into the floating ring sealing cavity, the seal oil leaks to the inner side of the inner floating ring and the outer side of the outer floating ring along the gap of the floating ring. The rotor rotates at high speed, and oil sealing in the floating ring gap forms oil film with certain bearing capacity under the action of the rotating shaft, and the oil film lifts the floating ring to lubricate the floating ring and the shaft neck to reduce friction and wear. In addition, the sealing oil also has the functions of lubrication and cooling.
The inner and outer floating rings of the floating ring seal can move radially, so that the rotor can compensate the different concentricity and radial swing of the rotor relative to the box body. The tightness of the surface contact of the floating ring sections depends on the fact that the end faces are mutually attached, and the two compensating rotors are in different concentricity and radial swinging relative to the box body. The tightness of the floating ring section contact is ensured by means of the arc fitting of the end faces, the flatness and the roughness of the two surfaces. The floating ring is pressed against the section by means of a spring and a pressure drop of the working medium. The inner floating ring is generally one because the pressure difference between two sides of the inner floating ring is smaller. The pressure difference at two sides of the outer floating ring is large, and multiple outer floating rings can be selected according to the situation in order to prevent the oil drainage from being excessively large. The function of the anti-rotation pin is to prevent the floating ring from rotating along with the shaft, but the anti-rotation pin does not influence the normal floating of the floating ring. The O-ring is used for preventing sealing oil from leaking from the contact surface between the floating ring and the shell, and is used for assisting sealing.
The sealing effect of the floating ring sealing device is directly related to the floating ring gap, and the floating ring gap is reduced as much as possible from the viewpoints of reducing oil leakage and improving the floating ring efficiency, but too small gap can cause the deterioration of the working condition of the floating ring and even the generation of the floating ring shaft-locking fault.
