Description
Technical field
The invention belongs to the technical fields of automobile water-cooling, and in particular to a kind of contactless water seal mover.
Background technique
In the inside of auto pump, automotive water seal is installed, pump shaft is sealed, automotive water seal includes one group of phase interworking
The water seal mover and water seal stator of conjunction, water seal mover and motor axis connection, as motor shaft rotates together, water seal stator then with water
Pump case is fixed, and water seal is used to prevent the recirculated water in pump from leaking out from the gap of motor shaft.Seen automobile currently on the market
Water seal, the envelope overwhelming majority is all direct contact seal, is primarily present deficiency below: 1, in long-time in use, rotating ring and quiet
Only the contact position of ring is gradually worn, until can not achieve automatic compensation, generates gap, water seal effect is caused to decline, due to rotation
Ring and stationary ring will necessarily contact friction, even if being changed to the better material of wear resistance, can also gradually wear out in use, temporary solution
It does not effect a permanent cure.Moreover, need entire sealing structure for water that will remove, the water seal more renewed when water seal is once worn up to a certain degree,
Cost is also relatively high.
Summary of the invention
The technical problem to be solved by the present invention is to solve the above shortcomings of the prior art and to provide a kind of contactless water seals
Structure of mover, even if, liquid practical with structure enters water seal, what can also be discharged when mover stops operating is contactless
Water seal mover.
To realize the above-mentioned technical purpose, the technical scheme adopted by the invention is as follows:
A kind of contactless water seal mover, in which: including mover body, mover body structure in a ring, on mover body
Surface is provided with the water seal piece of several ring shapes, and water seal piece is arranged concentrically, and diameter is different, and the lateral surface of mover body is set
It is equipped with the portion of being screwed, mover body is sealedly and fixedly connected by the portion that is screwed with mover seat, if mover body is provided with
Dry leak paths, leak paths run through mover body up and down, and for leak paths upper end opening between two water seal pieces, leak is logical
For road lower ending opening in the lower surface of mover body, water flow can flow to lower ending opening from leak paths upper end opening, in mover body
It is provided with transversal chamber, transversal chamber is horizontally through leak paths, transversal intracavitary to be equipped with transversal plate and spring, spring one end and mover
Main body is fixedly connected, and the other end is connect with transversal plate, and transversal plate is laterally disposed, is provided on the plate body of transversal plate and leak paths
One-to-one hole, when mover body is stood, the hole on transversal plate is aligned with leak paths, is kept leak paths unimpeded, is worked as mover
Main body is servo-actuated stroma rotation, and transversal plate is traversing under centrifugal force, and the hole on transversal plate is staggered with leak paths, and leak paths are closed
It closes.
To optimize above-mentioned technical proposal, the concrete measure taken further include:
Above-mentioned water seal piece is low wide and up narrow ring slice.
The above-mentioned outside smooth curved in water seal piece top.
Above-mentioned transversal chamber is provided with spring cavity close to the side of mover body ring heart, and spring is mounted in spring cavity, bullet
Spring in a relaxed state when, the hole on transversal plate is aligned with leak paths, spring in a stretched state when, hole on transversal plate with
Leak paths are staggered.
Above-mentioned mover body is stainless steel production.
Above-mentioned water seal piece is stainless steel production.
Above-mentioned water seal piece is equidistant with one heart on mover body to be laid, and there are two leaks for tool between two adjacent water seal pieces
Channel upper end opening.
Above-mentioned transversal plate is that glass or stainless steel make.
Above-mentioned water seal piece and mover body integrally casting.
The contactless water seal mover of the utility model, upper part and corresponding stator non-contacting seal have prevented pressure
The water of power enters the junction of water seal and motor shaft from water seal mover top, when water pump is rotated, water seal mover top
Water seal piece and stator not in contact with, only from it is close, the water outside water pump can be gradually from the gap into water seal mover upper surface
Between water seal piece, into after full water, water can be gradually to the gap between second water seal piece for gap between first water seal piece
Overflow into, since water seal piece upper end is bent outwardly, the water in water seal piece gap water pump rotation provide centrifugal force effect under,
Mobile trend outside the oriented water seal piece of meeting, therefore, after the pressure that water is offset by first and second water seal piece gap, liquid
Body only can be very slowly to third, the 4th water seal piece gap filling, the water seal piece gap setting of contactless water seal mover
The leak paths that can be opened when water pump stops operating in the case where can not having water in water pump leak out water, guarantee
Ponding is not had in water seal.The water seal mover of the utility model is due to discord stator contact, longer life expectancy.
