High-pressure large-torque axial sealing and lubricating system

Abstract

The invention relates to a high-pressure large-torque axial sealing and lubricating system. A second-stage packing box, second-stage packing and a second-stage gland are arranged on the periphery of the upper portion of a transmission shaft, a first-stage packing box, first-stage packing, an oil separating ring and a first-stage gland are arranged on the periphery of the lower portion of the transmission shaft, the lower end of the second-stage packing box is connected into the first-stage packing box in an inserted mode through middle nut studs, and the second-stage packing box and the first-stage packing box are provided with lubricating oil inlets respectively. The lubricating system comprises a main oil station, an oil supplementing station, a satellite station and a distributor. The main oil station internally comprises a main oil tank, an oil supplementing pump, a main oil filling pump and a main filter, an outlet of the main filter is connected to the satellite station, and the satellite station delivers lubricating oil to lubricating oil inlets through the distributor. By means of the design, the high-pressure large-torque axial sealing and lubricating system is compact in connection and reliable in oil supplying performance, the oil can be automatically supplemented, grading pressure partition and grading lubricating are beneficial to even distribution of radial sealing force and lubrication, abrasions are reduced, and the high-pressure large-torque axial sealing and lubricating system has the advantages of being good in sealing effect and high in operation stability.

Description

technical field [0001] The invention relates to a high-pressure and high-torque axial sealing and lubrication system. Background technique [0002] Packing seal is generally made stuffing box on the box body, put the packing rich in compressibility and resilience into it, rely on the axial pressing force of the gland to convert into radial sealing force, and use the elastic deformation of the sealing packing to compensate The wear of the sealing surface isolates the sealed space from the outside world, blocks the leakage gap, and prevents the medium from leaking out so as to play a sealing role. It is widely used in the sealing of rotation, reciprocation and various static states. It has the characteristics of simple structure, convenient operation and replacement, wide source of materials, easy processing, low cost, wide application range and reliable sealing. But as a dynamic seal, its disadvantage is precisely because the elastic deformation of the packing compensates th...

Problems solved by technology

[0003] In order to overcome the fact that the wear caused by friction directly affects the sealing performance and service life of the packing seal when the ordinary packing seal is used in the dynamic seal in the prior art, and the structural design of the lubrication system matching the above sealing device is complicated and the reliability of the oil supply For poorer problems, the present invention provides a high-pressure, high-torque axial seal and lubrication system. The high-pressure, high-torque axial seal and lubrication system has a compact structure, not only reliable oil supply performance, but also automatic oil replenishment and step-by-step pressure division. And lubrication is conducive to the uniform distribution and lubrication of radial sealing force, reducing wear, good sealing effect, long service life and high operation stability
