Abstract
The invention relates to a large-scale pump storage group generator motor two-way pump tile structure, and the two sides of the pump tile are designed with same pump grooves, thereby realizing the purpose that only one piece of pump tile can satisfy the structure need when the generator motor rotates to two opposite directions.
Description
Technical field: the present invention relates to a kind of large-scale pumped storage power unit generation motor two-way pump tile structure
Background technique: conventional hydraulic turbine generator is because only towards a direction rotation, so only at side design pump groove.Large-scale pumped storage power unit generation motor overlooks being rotated counterclockwise sometimes because the needs of self structure overlook turning clockwise sometimes, if Design of Hydrogenerator routinely realizes circulation with the pump watt ability of establishing one times more.If like this, a pump watt place guide bearing size is added be twice, it is very many to cause the guide bearing loss to increase, and the size of guide bearing place frames also can strengthen, and influences the design size of whole unit and the increase of design cost.
Summary of the invention: the objective of the invention is to disclose a kind of large-scale pumped storage power unit generation motor two-way pump tile structure simple in structure.Technological scheme of the present invention is: a kind of large-scale pumped storage power unit generation motor two-way pump tile structure, design measure-alike left pump groove (2) and right side pump groove (3) in the both sides of pump watt (1), overlook when turning clockwise when unit, right side pump groove (3) plays the effect of pump; When unit is overlooked when being rotated counterclockwise, left pump groove (2) plays the effect of pump, be used to realize that when generator motor during only watt just can satisfy the structure needs with a pump, lubricating to cool off for the thrust-bearing outer circulation provides circulation power to opposite both direction rotation.When the sense of rotation of generator motor is clockwise for overlooking, the internal surface of pump watt can make deep fat pump concentrated flow to the left moving with the high pressure oil that contact surface produced of axle, pass through external pipeline system, the flow direction is arranged in the outer cooler of oil groove, stay again and get back in the thrust bearing oil sump, finish once circulation.When the sense of rotation of generator motor is counterclockwise for overlooking, the internal surface of pump watt can make deep fat pump concentrated flow to the right moving with the high pressure oil that contact surface produced of axle, by external pipeline system, flows to and is arranged in the outer cooler of oil groove, stay again and get back in the thrust bearing oil sump, finish once circulation.Large-scale pumped storage power unit generation motor two-way pump tile structure both provided circulation power for the lubricated cooling of thrust-bearing outer circulation, simplified the structure again.

Embodiment
As Fig. 1, Fig. 2, large-scale pumped storage power unit generation motor two-way pump tile structure shown in Figure 3, design measure-alike left pump groove 2 and right side pump groove 3 in the both sides of pump watt 1, to overlook when turning clockwise when unit, right side pump groove 3 plays the effect of pump; Overlook when being rotated counterclockwise when unit, left pump groove 2 plays the effect of pump, is used to realize when generator motor during to opposite both direction rotation, only watt just can satisfy the structure needs with a pump, and lubricating to cool off for the thrust-bearing outer circulation provides circulation power.
Claims (1)
1. large-scale pumped storage power unit generation motor two-way pump tile structure, it is characterized in that: design measure-alike left pump groove (2) and right side pump groove (3) in the both sides of pump watt (1), overlook when turning clockwise when unit, right side pump groove (3) plays the effect of pump; When unit is overlooked when being rotated counterclockwise, left pump groove (2) plays the effect of pump, be used to realize that when generator motor during only watt just can satisfy the structure needs with a pump, lubricating to cool off for the thrust-bearing outer circulation provides circulation power to opposite both direction rotation.
