Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises bearing support 1, bearing housing 2, thrust-bearing 4 and balancing drum 15, balancing drum 15 be positioned at vertical pump the pump housing, be socketed on the vertical pump transmission shaft 14, with transmission shaft 14 interlocks.Bearing support 1 is fixed on the pump housing, and transmission shaft 14 is by passing in the bearing support 1, and is passed by the other end.Be arranged with bearing housing 2 on the transmission shaft 14 in the bearing support 1, the bottom of bearing housing 2 is provided with dovetail groove 18, has first oil through 16 on the bearing housing 2 and communicates with dovetail groove 18.On bearing housing 2, be connected with locking nut 3.Between bearing support 1 and the locking nut bearing housing 2 more than 3 is bearing chamber, and inside is provided with the thrust-bearing 4 that is sheathed on the bearing housing 2.Between bearing support 1 and the locking nut bearing housing 2 below 3 is accumulator, the middle and lower part of bearing housing 2 is positioned at accumulator, be provided with outside thread, locking nut 3 was connected with bearing housing 2 by outside thread, also can bring sub-fraction lubricant oil into bearing chamber in addition, most of lubricant oil is to be realized by first oil through 16 on the bearing housing 2, when pump operation, the dovetail groove 18 of rotation makes lubricant oil pass through first oil through 16 and arrives thrust-bearing 4 tops for lubricant oil provides centrifugal force.Thrust-bearing 4 tops are provided with the bearing gland 6 that is fixed in bearing support 1.Have second oil through 17 that communicates with accumulator on the bearing support 1, above bearing support 1, be connected with dustproof dish 7, have air relief cock 9 on it.Bearing gland 6 is placed in the space of dustproof dish 7 and bearing support 1 formation, also is provided with in this space and adjusts nut 8, and it is fixed on the bearing housing 2, is used for fixing and adjusts bearing housing 2.Be equipped with water-cooling tube 11 in the accumulator, do not communicate with accumulator, be provided with two warter connections 13 of one-in-and-one-out on bearing support 1, water-cooling tube 11 links to each other with external cooling water source by two warter connections 13, forms closed circuit in accumulator.Bearing support 1 is provided with the oil ga(u)ge 10 of observing the accumulator oil mass, can show oil level, can observe the height of oil level in the accumulator by oil ga(u)ge, determines whether and need refuel in accumulator.Also have the plug 12 of oil extraction on the bearing support 1, lubricant oil in accumulator has been used a period of time, when containing impurity, can open plug 12 bleeds off the oil that accumulator contains impurity, add new clean lubricant oil again, when especially just beginning to refuel, need to feed lubricant oil two or three time, could be with processing and transportation, deposit in the process fine impurity in the grease chamber and all take out of, by the time lubricant oil becomes after the cleaning, the plug 12 of screwing on again, at this moment the lubricant oil that adds again is only to thrust-bearing and provides lubricated.Bearing support 1 is provided with platinum resistor temperature measuring element 5, its with bearing chamber in thrust-bearing 4 contact, can directly measure the temperature of thrust-bearing 4, when the temperature of thrust-bearing 4 exceeds setting value, the signal that platinum resistor temperature measuring element 5 measures can send alarm signal after changing, the assurance thrust device is worked under good state.When observing oil level in the accumulator by oil ga(u)ge 10 when low, can open air relief cock 9, inside lubricating oil filling, lubricant oil can flow in the accumulator by first and second oil through 16,17 on bearing support 1 and the bearing housing 2.
Working principle of the present utility model is:
The utility model is as balanced controls, and the axial force that vertical pump produces balances 90～95% by balancing drum 15, because the variation of vertical pump operating mode and the error of Axial Force Calculating, axial force can not complete equilibrium, and remaining axial force is just born by thrust-bearing 4.When pump turns round, the lubricant oil that the dovetail groove 18 of rotation stirs in the accumulator, lubricant oil in dovetail groove 18 passes through action of centrifugal force, arrive thrust-bearing 4 tops by first oil through 16 on the bearing housing 2, be positioned at bearing housing 2 external thread sections of thrust-bearing 4 bottoms, also bring less amount of lubrication oil into bearing chamber by outside thread, and unnecessary lubricant oil can flow back in the accumulator by second oil through 17 on the bearing support 1.Thereby formed the lubrication oil circulation loop, thrust-bearing 4 has been carried out lubricated fully effectively.As long as vertical pump is moving, the selflubricating of thrust-bearing just can not be interrupted.When vertical pump starts, open external cooling water source, cooling water enters in the water-cooling tube 11, can take away the heat of lubricant oil.
The utility model has realized that the condensate pump end thrust born by self, greatly reduce cost and occupy the space, the condensate pump that can be used for 300MW～1000MW fire (nuclear) electricity, and bigger extending space arranged, the vertical pump that can also be used for other field, the small-sized diagonal pumps that also can be used for fire (nuclear) electricity are first-class.
