During work, described impeller is followed main shaft and is rotated together, thereby by centrifugal force the lubricant oil of support bottom is got to the oil inlet pipe place, and flow to the junction plane place of main shaft and interior circulation bearing through oil inlet pipe and described oil inlet hole, and this junction plane is lubricated, and the deep fat that lubricated back produces flows in the fuel tank of described support bottom, and is cooled off by described cooler.
Because during the hydraulic turbine generator startup-shutdown; the rotating speed of main shaft is all lower; it is also fewer that impeller is stamped the lubricant oil that comes so; thereby cause the oil slick thickness at junction plane place of main shaft and interior circulation bearing not enough; so not only can influence lubrication effect; and can influence working life of bearing inevitably, and the tile kilning phenomenon takes place even, be badly in need of solving the problems of the technologies described above for this reason.
The model utility content
Technical problem to be solved in the utility model is to provide circulation bearing lubrication assistant structure in a kind of hydraulic turbine generator main shaft, so that there is the lubricating oil oil film of adequate thickness at main shaft and interior circulation bearing junction plane place when guaranteeing the hydraulic turbine generator startup-shutdown.
The technical solution of the utility model is as follows: circulation bearing lubrication assistant structure in a kind of hydraulic turbine generator main shaft, the main shaft (1) that comprises rotation, this main shaft (1) is carried on radially on the bearing shell (2), this radially bearing shell (2) docked by last half-watt and following half-watt and fixedly form; Described radially bearing shell (2) is located on the bearing support (4), and bearing support (4) and bearing cap (5) thus be connected to form annulus fixed radial bearing shell (2), it is characterized in that: outside described bearing support (4), be provided with an oil pump (6), the oil outlet end of this oil pump is by oil pipe (7) and joint (8), and joint (8) is connected in the oil inlet hole on the described bearing cap (5); Oil inlet hole on the described bearing cap (5) directly links to each other with repairing hole (2a) on the half-watt on the bearing shell (2) radially, and the inside and outside wall of half-watt is run through in this repairing hole (2a).
The utility model has been set up an oil pump (6) outside described bearing support (4) on the basis of conventional construction, the oil outlet end of this oil pump is by oil pipe (7) and joint (8), and joint (8) is connected in the oil inlet hole on the described bearing cap (5); Oil inlet hole on the described cover (5) is communicated with repairing hole (2a), and the top of circulation bearing (2) in described is opened in this repairing hole (2a), and runs through the inside and outside wall of circulation bearing (2) in this.
Adopt above technological scheme; before the hydraulic turbine generator startup-shutdown; the operator can inject the lubricant oil of capacity in advance by described oil pump (6) to the junction plane place of main shaft and interior circulation bearing; thereby form the lubricating oil oil film of adequate thickness at this junction plane place; can not only guarantee to influence lubrication effect well like this; and can guarantee working life of bearing effectively; and avoid taking place the generation of tile kilning phenomenon fully; just solved the defective of conventional construction well by little change; easy to implement; have good technology and economic value, be suitable for extensively promoting the use.
As preferably, described repairing hole (2a) is radial hole.
For the ease of installing, described oil pump (6) is fixed by oil pump seat (9) and the bottom of support (4).
Beneficial effect: the oil pump in this lubrication assistant structure (6) controlled processing procedure order before the hydraulic turbine generator startup-shutdown is opened automatically; and by this oil pump (6) in advance to the lubricant oil of the junction plane place injection capacity of main shaft and interior circulation bearing; thereby form the lubricating oil oil film of adequate thickness at this junction plane place; can not only guarantee to influence lubrication effect well like this; and can guarantee working life of bearing effectively; and avoid taking place the generation of tile kilning phenomenon fully; just solved the defective of conventional construction well by little change; easy to implement; have good technology and economic value, be suitable for extensively promoting the use.
