Abstract
The utility model discloses a device for sealing magnetic fluid for water pump, its characterized in that: including axle and magnetic conduction seat not, the magnetic conduction seat is not fixed in epaxially and becomes an airtight space with the axiform, including two bearings in the airtight space, the bearing inlays in the axle and not between the magnetic conduction seat, still include four permanent magnet in the airtight space, two permanent magnet in the outside inlay and form two O type sealing washers on the magnetism boots, are full of the magnetic current body in the clearance between permanent magnet and the axle. The device makes the magnetic current body be full of in the space of setting for under the effect of even stabilizing magnetic field, sets up multistage " O type sealing washer " to reach sealed effect, it is sealed respond well, and can not leak gas.
Description
Technical field
This utility model relates to water pump field, particularly a kind of water pump device for sealing magnetic fluid.
Background technology
The seal form of current water pump is the operating mode that mechanical seal or packing seal, mechanical seal or gland sealed the most all can not meet that present water pump produces, and frequently results in and leaks and packing seal and the damage of mechanical seal.
Utility model content
For solving the problems referred to above in existing water pump packing field, the purpose of this utility model is to provide a kind of good seal, the water pump device for sealing magnetic fluid that will not leak gas.
For achieving the above object, this utility model offer techniques below scheme:
A kind of water pump device for sealing magnetic fluid, including axle and not magnetic conductance seat, described not magnetic conductance seat is fixed on axle and forms a confined space with axle, two bearings are included in described confined space, described bearing is embedded in axle and not between magnetic conductance seat, also include in described confined space that four permanent magnets, two, outside permanent magnet are embedded on magnetic boots two O RunddichtringOs of formation, in the seal clearance between permanent magnet and axle, be full of magnetic fluid.
Preferably, described not magnetic conductance seat is provided with an O RunddichtringO.
Preferably, described permanent magnet is provided with pole tooth teeth groove near axle side.
This utility model has the advantages that (1) this device good seal, will not leak gas, modern times Magneticfluid Seal Technique is applied in water pump, thus solve problems of the prior art；(2) when magnetic fluid injects the gap in magnetic field, it can be full of whole gap, forms a kind of " the O RunddichtringO of liquid "；(3) under the effect of uniform steady magnetic field, make magnetic fluid riddle in the space of setting, it is established that multistage " O RunddichtringO ", thus reach the effect sealed；Every grade of sealing ring typically can bear the pressure reduction more than 0.15～0.2 atmospheric pressure.Total pressure-bearing is pressure reduction sums at different levels, is typically designed as 2.5 atmospheric pressure, and the most pressure progression with liquid round section joint ring increases and increases.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be done simple introduction below, apparently, accompanying drawing in describing below is embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Accompanying drawing 1 is the front view of this utility model embodiment.
In accompanying drawing, 1 is axle, and 2 is not magnetic conductance seat, and 3 is bearing, and 4 is permanent magnet, and 5 is magnetic boots, and 6 is O RunddichtringO, and 7 is seal clearance, and 8 is magnetic fluid.
Detailed description of the invention
Below by specific embodiment, this utility model is further described.
A kind of water pump is with device for sealing magnetic fluid as shown in Figure 1, including axle 1 and not magnetic conductance seat 2, wherein, magnetic conductance seat 2 is not fixed on axle 1 and forms a confined space with axle, including two bearings 3 in this confined space, bearing 3 is embedded in axle 1 and not between magnetic conductance seat 2, also includes four permanent magnets 4 in this confined space, two, outside permanent magnet is embedded on magnetic boots 5 two O RunddichtringOs 6 of formation, is full of magnetic fluid 8 in the seal clearance 7 between permanent magnet and axle.
Alternatively, it is also possible to be provided with an O RunddichtringO on not magnetic conductance seat.
At permanent magnet, pole tooth teeth groove can also be set near axle side, be more beneficial for sealing the flowing of magnetic fluid in space.
Principle of the present utility model and embodiment are set forth by specific embodiment used herein, and the explanation of above example is only intended to help to understand method of the present utility model and core concept thereof.The above is only preferred implementation of the present utility model, should be understood that, finiteness due to literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, on the premise of without departing from this utility model principle, it is also possible to make some improvement, retouch or change, it is also possible to above-mentioned technical characteristic is combined by rights；These improve retouching, change or combine, or the most improved design by utility model and technical scheme directly apply to other occasion, are regarded as protection domain of the present utility model.
