SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to provide a vertical water pump guide bearing with an annular water supply device, so that a water pump shaft stop and the guide bearing are sufficiently lubricated and cooled before a water pump is started, the starting stability of a unit is ensured, the service lives of the guide bearing and a water pump shaft are prolonged, and the overhaul and maintenance cost is reduced.
The technical scheme is as follows: the water pump comprises a water pump shaft and a water pump shaft stop, wherein the water pump shaft stop is arranged on the outer side of the water pump shaft, a guide bearing is arranged on the water pump shaft stop, a sealing element is arranged on the guide bearing, a water supply device is arranged in the sealing element, a plurality of water outlets are annularly arrayed at positions of the water supply device corresponding to the surface of the water pump shaft stop, and cooling water is sprayed to the surface of the water pump shaft stop through the water outlets, so that the surfaces of the guide bearing and the water pump shaft stop are lubricated and cooled before the water pump is started.
Sealing member internally mounted have annular water supply installation, realize that the water pump starts the preceding fully lubricated cooling of guide bearing and water pump axle shelves surface, avoid dry friction to take place between guide bearing and the water pump axle shelves surface, guarantee that the unit starts stably, the life of extension guide bearing and water pump axle shelves reduces overhaul maintenance cost.
The top of the annular water supply device is provided with a plurality of water inlets which are respectively communicated with the sealing element water inlet pipe.
The water inlet is communicated with the sealing element water inlet pipe, so that lubricating and cooling water is uniformly sprayed to the surface of the water pump shaft baffle through the water outlet after being introduced into the annular water supply device through the sealing element water inlet pipe.
And after the lubricating and cooling water is introduced into the annular water supply device through the sealing part water inlet pipe, the lubricating and cooling water is uniformly sprayed to the surface of the water pump shaft bumper through the water outlet.
The annular water supply device is arranged in the sealing piece through a connecting bolt, lubricating and cooling water is filled in the annular water supply device, and after the lubricating and cooling water is introduced into the annular water supply device through the water inlet pipe of the sealing piece, the lubricating and cooling water is uniformly sprayed to the surface of the water pump shaft stop through the water outlet.
The annular water supply device is positioned above the guide bearing.
The guide bearing and the sealing element are arranged at the outlet shaft of the water outlet flow passage through bolts.
The working principle is as follows: after the lubricated cooling water lets in annular water supply installation through the sealing member inlet tube, evenly spray to water pump axle shelves surface through the delivery port, realize the water pump before starting to guide bearing and water pump axle shelves surface abundant lubricated cooling, avoid the dry friction to take place between guide bearing and the water pump axle shelves surface, guarantee that the unit starts stably, the life of extension guide bearing and water pump axle shelves reduces the overhaul maintenance cost.
Has the advantages that: the utility model can realize the sufficient cooling and lubrication of the water pump starting guide bearing and the water pump shaft stop, ensure the stable starting of the unit, prolong the service life of the guide bearing and the water pump shaft stop and reduce the overhaul and maintenance cost.
