Abstract
A vertical type pump used bearing box bearing thin oil lubricating device is composed of a bearing box body, a dynamic sealing ring, an oil guiding sleeve, an angular contact ball bearing, etc. The oil guiding sleeve is arranged for collecting the thin oil thrown out by a lower bearing rolling element and guiding into an upper bearing rolling element; the reverse acting spiral groove seal is arranged on the inner cylindrical surface of the dynamic sealing ring matched with an oil sealing sleeve; a return chute is formed on a bearing cover; a return chute is formed in the bearing box body for enabling the oil spilled from the upper part bearing to return to an oil collecting chamber of the bearing box; and the oil collecting chamber of the lower part of the bearing box adopts the large-cavity structure. The vertical type pump used bearing box bearing thin oil lubricating device can ensure that the upper and the lower part bearings are lubricated effectively, and cool the thin oil, thereby prolonging the bearing's service life. As long as an oil cup of an oil level indicator has oil level display, and 1/2 of the lower bearing rolling element is immerged in the oil, the upper part bearing can be lubricated without oil leakage.
Description
Technical field:
The utility model relates to a kind of vertical pump bearing housing bearing thin oil lubrication device, to improve the stability and the reliability of vertical long shaft pump operation, can be widely used in industries such as metallurgy, petrochemical industry, mining and carry sewage.
Background technique:
The bearing housing that major axis pump in the existing pump industry uses roughly adopts three kinds of structures: the one, only with a thrust-bearing, bear the axial force that the rotor weight of pump and when operation produce by thrust-bearing, whole rotor part does not have radial location, there is dynamic unbalance owing to rotor part in the pump operation process, rotor part can swing, cause the pump operation vibration big, cause bearing wear fast; Two are to use two thrust-bearings, adopt grease lubrication, behind the long-play, because temperature rises, fall into the bearing housing bottom after the fusing of top grease, cause after the upper bearing de-oiling the too high and scaling loss of temperature; The 3rd, a thrust-bearing is adopted in the bottom, and the bearing housing structure of a radial ball bearing is adopted on top, adopts the thin oil lubricant mode, and lower bearing is immersed in the oil, but upper bearing is lubricated not good, and operation a period of time rear bearing lost efficacy, and working life is short.
Summary of the invention:
The purpose of this utility model will provide a kind of vertical pump bearing housing bearing thin oil lubrication device exactly, and it can overcome the bearing housing middle (center) bearing lack of lubrication of existing major axis pump well, the problem that working life is short.The purpose of this utility model is to realize like this, a kind of vertical pump is made up of bearing housing, oil sealing cover, rotary packing ring, Oil Guide cover, angular contact ball bearing, deep groove ball bearing, bearing gland, bearing housing gland with the bearing housing bearing thin oil lubrication device, it is characterized in that: in bearing housing, be provided with main shaft, the upper end of main shaft is with the Oil Guide cover, described Oil Guide cover small column is with deep groove ball bearing on the surface, and the inner chamber that the step end face that the Oil Guide cover is provided with forms is in angular contact ball bearing among half parcel; The lower end of main shaft is with the oil sealing cover, is with rotary packing ring on the external cylindrical surface of oil sealing cover, is with angular contact ball bearing on the rotary packing ring outer round surface, and the inner cylinder that described rotary packing ring cooperates with the oil sealing cover is provided with the sealing of reverse acting spiral groove; Be provided with bearing gland above the deep groove ball bearing, described bearing gland is provided with oil-return groove; Bearing housing inside is provided with the oil-return groove that the oil that upper bearing is spilt is got back to the bearing housing gathering room, and bearing housing bottom gathering room adopts big cavity configuration.The automatic cycle of thin oil in two bearings up and down can guarantee lubricated effectively top and the bottom bearing in the utility model bearing housing, can make the thin oil cooling again, and bearing life is long.As long as the lubricating cup of oil level indicator has oil level to show that then lower bearing rolling element 1/2 is immersed in the oil, just can realize the lubricated of upper bearing.Adopt the sealing of rotary packing ring reverse acting spiral groove, guarantee not take place oil leakage phenomenon.
