Abstract
The utility model provides a thrust device used for submersed pumps (diving pumps, submersible pumps, etc.), which adopts a liquid cushion theory. The utility model has the main structure that pumping structure is arranged on a dynamic salver, and when the submersed pump revolves, the liquid is pumped into a cavity formed by the dynamic salver and a static salver to hold the dynamic salver; and a liquid cushion is formed between the dynamic salver and a pushing plate. The utility model adopts the liquid cushion theory and therefore no direct mechanical friction exists between the dynamic salver and the pushing plate thus overcoming the problems of wearing, crushing, and fusing, etc. to the pushing plate. Moreover, mechanical efficiency of the submersed pump can be enhanced and power loss can be reduced.
Description
The utility model relates to a kind of immersed pump axial thrust brake.
Immersed pump such as submersible pump, oil-immersed pump lift is big more, and axial force is also big more.When axial force is excessive, can make very quick-wearing of thrust disc, even pressure break or fusing.Although people have taked a lot of measures, this problem does not still thoroughly solve, and thrust disc damages and is still an important source of trouble that causes the immersed pump operational failure.The utility model proposes a kind of long-lived immersed pump fluid cushion thrust device at this problem.
As shown in Figure 1, general plotting of the present utility model is: fixing moving pallet 7 on immersed pump motor shaft or pump shaft, on the housing of electric machine casing or pump, decide pallet 10, move pallet 7 and decide to form between the pallet 10 cavity 11 that can dynamically keep fluid pressure, during immersed pump work, in cavity 11, inject liquid by oil hydraulic pump, hold up moving pallet 7, between thrust disc 8 and moving pallet 7, form fluid cushion.Moving, decide to be provided with on the pallet moving pallet and move limit stoper, in case the displacement of stop pallet is too much.
Below be hydraulic pressure pump structure embodiment: on moving pallet 7, offer liquid entering hole 2 near motor shaft or pump shaft position in cavity 11 outsides one side, on moving pallet 7, offer liquid outlet 3 in the inboard sides of cavity 11 away from motor shaft or pump shaft position, liquid entering hole 2 is connected by passage 12 with liquid outlet 3.When moving pallet 7 high speed rotating, because centrifugal action, liquid constantly enters from liquid entering hole 2, flows out from liquid outlet 3, enters cavity 11, causes cavity 11 internal pressures to raise, and holds up moving pallet 7.
Below be the cooperating structure embodiment who forms the moving pallet 7 of cavity 11 and decide pallet 10: the moving pallet 7 that forms cavity 11 adopts maze-type structure with the cooperation place of deciding pallet 10, promptly be processed with some roads concentric annular projection, seal ring movingly 4 that can be mutually nested on the body separately in moving pallet 7 and the cooperation place of deciding pallet 10.
Below be the embodiment who decide pallet upper limit device moving: at moving pallet 7 with decide to process some breach on the seal ring 4 of pallet 10, form restraining groove 5, when moving pallet 7 moves on to certain altitude under the hydraulic pressure, restraining groove 5 begins to reveal cavity 11 internal liquids, cause pressing in the cavity 11 reducing, limited on the moving pallet 7 and moved past the position.
In the very big occasion of axial force, the utility model can also use by plural serial stage, to improve anti-pressure ability
Description of drawings is as follows: Fig. 1 is the utility model structure principle chart, and 1 is motor shaft or pump shaft among the figure, the 2nd, and liquid entering hole, the 3rd, liquid outlet, the 4th, seal ring, the 5th, restraining groove, the 7th, moving pallet, the 8th, thrust disc, the 10th, decide pallet, the 11st, cavity.
Along with the lift of modern immersed pump and flow improve constantly and increase, axial force becomes gradually Be the outstanding problem that this class pump work lost efficacy, what the utility model proposed deals with problems Scheme adopt the fluid pressure balancing axial thrust, have hardly mechanical wear, greatly prolong Work period between twice maintenance. Obviously the utility model is owing to take fluid cushion, the friction resistance Power is minimum, can improve the mechanical efficiency of immersed pump, reduces electric energy loss, be one valuable Advantage.
