Abstract

An energy-storing type compensator of a stirrer belongs to the technical field of mechanical sealing and comprises a press sleeve, a bearing press cover, an end cover, an expansion joint assembly and a shaft sleeve, a bearing inner sleeve, a bearing, an oil storage sleeve internally provided with lubricating oil and a mechanical seal, wherein the shaft sleeve, the bearing inner sleeve, the bearing, the oil storage sleeve internally provided with lubricating oil and the mechanical seal are arranged in the expansion joint assembly. Two ends of the expansion joint assembly are respectively connected with the bearing press cover and the end cover, the shaft sleeve is arranged in the expansion joint assembly, the bearing inner sleeve and the oil storage sleeve are respectively sleeved at two ends of the shaft sleeve, the bearing is installed on the bearing inner sleeve, the mechanical seal is installed in a cavity defined by the bearing press cover, the expansion joint assembly, the bearing inner sleeve, the bearing and the oil storage sleeve, and the press sleeve is connected with the end portion of the bearing inner sleeve. When the energy-storing type compensator works, the shaft sleeve is installed on a driving shaft of the stirrer, and the end cover is fixed on a stirrer machine body. The compensator organically combines the mechanical seal and the expansion joint assembly, is compact in structure, convenient to disassemble and stable and reliable in use and resolves the problem of sealing of rotating shafts of such equipment, thereby being suitable for sealing of vertical rotating shafts with swinging and axial jumping.

Description

technical field [0001] The invention belongs to the technical field of mechanical seals, in particular to an agitator energy storage compensator. technical background [0002] In the existing agitator, the seal of the rotating shaft basically adopts two forms of packing seal and mechanical seal. The packing seal has disadvantages such as high leakage rate, short service life, frequent maintenance, friction between the packing and the shaft (or sleeve), friction resistance, large power loss, and wear of the shaft (or sleeve). Since there is no effective sealing means, packing seals are still commonly used. Using a single mechanical seal should be a reasonable sealing solution in theory. However, the agitator itself has a large swing, and after a long running time, there will be axial displacement. The mechanical seal itself has high requirements on the operation accuracy of the equipment, and cannot adapt to the operating conditions of the agitator, and is very unstabl...
