Description
Technical field
The utility model relates to technical field of motors, in particular to a kind of magneto.The utility model further relates to one kind
Three float-ball type aerators.
Background technique
In modern aquaculture industry, oxygen increasing equipment is a kind of common ancillary equipment, common in these oxygen increasing equipments
Be three floating ball paddle aerators, it generally includes speed reducer, three pull rods being fixedly connected on speed reducer and fixation
It is connected to the floating ball of three pull rod outer ends, speed reducer is driven by three-phase motor, and the shaft of speed reducer connects impeller.Aerator
In use, since the rated speed of three-phase motor is certain value, in order to obtain suitable wheel speed, speed reducer subtracts
Speed ratio is most important, and used speed reducer usually has primary speed-down, double reduction on the market, using the deceleration of primary speed-down
Machine is limited by manufacturing cost and reduction ratio, causes the diameter of central gear smaller, and teeth tooth is away from less than normal, in operational process
In, it is easy to cause and grits one's teeth, so that later maintenance frequency is high, maintenance cost is high；And the speed reducer of double reduction is used, in speed reducer
Interior filling lubricating oil, at work, speed reducer fever to generate gas in speed reducer, lead to pressure increase in speed reducer,
A possibility that if gas can not be discharged in time, and there are oil leaks.In conclusion the three of existing three-phase motor additional deceleration machine are floating
The service life of ball paddle aerator is low, pollution is big.
, there is the magneto for oxygen increasing equipment, it may be assumed that direct current on the market in the problem that in view of speed reducer is used
Motor, it has many advantages, such as that electricity damage, copper loss are low, energy saving, is not necessarily to speed reducer, can meet revolving speed required for impeller, well
Three-phase motor combination speed reducer is solved the problems, such as oxygen increasing equipment.But existing magneto, shell are usually adopted
It is produced in batches with aluminium or iron, and using casting technique, the shell of casting and forming, it is also necessary to anti-oxidant treatment is carried out,
Exactly extend the service life of magneto, and the use environment of oxygen increasing equipment is: seawall, contact is seawater, in this ring
In border, seawater itself is a kind of strong corrosive medium, meanwhile, the rotation of magneto impeller, generated wave, wave, tide,
Stream, steam generate low frequency toward combined stress and impact, in addition marine microorganism, aufwuch and their metabolism to metal component again
Product etc. all generates direct or indirect acceleration, since the surface of magneto, machine to corrosion process: from magneto
Shell start to corrode, such as galvanic corrosion, spot corrosion, crevice corrosion.Since oxidation resistance is poor, in addition oxygen increasing equipment makes
With environment, so that the service life of the magneto of aluminium, iron is not still grown.Moreover, existing be used for oxygen increasing equipment forever
Magneto, only realizes sealing between machine shaft and shell by oil sealing, and poor sealing performance is easy water inlet, leads to nothing
Method normal use.
In numerous materials, in conjunction with factors such as cost performance, anti-corrosion capabilities, the technical staff in oxygen increasing equipment thinks, no
Rust steel be it is optimal for magneto shell manufacture material, still, the characteristic of stainless steel, and prevent it from aluminium,
Iron is equally produced in batches using lower-cost casting technique, the work of the existing production motor housing using stainless steel
Skill is unable to satisfy its use environment for being used for oxygen increasing equipment.
In addition, existing motor is provided with multiple tracks oil sealing for waterproof, this leads to the increase of manufacturing cost, also causes
The load of machine shaft increases.
Summary of the invention
The utility model will solve that existing underwater magneto oxidation resistance is low, and poor sealing performance, service life is short,
The low technical problem of failure rate.

24。
The gap 24 is 0.6-1.0mm.
It makes an explanation below to the working principle of the three float-ball type aerators of the utility model:
The three float-ball type aerators of the utility model, three floating balls 3 swim in sea, give and support to magneto 5, control
Device processed is in the top of main support 1, far from sea, and passes through the protective cover 18 of stainless steel, plays protection effect, pass through control
The control of device generates spray to stir to seawater, reaches oxygenation so that magneto 5 is maintained at the revolving speed of 150 turns/min
Purpose, in the present embodiment, fixed shaft 11 is fixed on motionless on main support 1 with rotor 8, fixed 6 phase of shell with stator 7
Shaft 11 is rotated, impeller 4 is set on shell 6, and when work, a part of impeller 4 is in seawater, in this case,
2/3rds parts of the shell 6 of the magneto 5 with impeller 4 are sunk under sea, one third be partially in sea it
On, that is to say, that gap (that is: the gap between 9 centre bore of shaft 11 and upper housing) is in sea at only the one of shell 6
On, this also can prevent seawater from impregnating flooded condition caused by this gap always while seawater realizes cooling to shell 6
Generation especially increase sealing mechanism 14 to further decrease the water inlet probability of magneto 5, rotating ring piece 16 is fixed on
On shell 6, with 6 synchronous rotary of shell, stationary ring piece 15 is bonded with rotating ring piece 16 always by the effect of spring 17, due to stationary ring piece 15
It is fully-flattened with the end face that rotating ring piece 16 fits, it is very smooth and flat, it is the opposite grinding contact of two planes when rotated, from
And sealing function is played, to prevent seawater from entering gap, moreover, stationary ring piece 15 and rotating ring piece 16 are the material of two kinds of different hardness
Matter generallys use wolfram steel and steel, in this way, the two opposite grinding, wear rate is lower, ensure that service life well；Finally, in order to
The sealing effect for further increasing sealing mechanism 14 has been arranged sealing shroud 19 outside sealing mechanism 14, and makes 19 inner wall of sealing shroud
Gap 24 between 14 outer wall of sealing mechanism is maintained at suitable distance, neither influences the normal rotation of shell, also prevents sea
Water touches the contact surface position between stationary ring piece 15 and rotating ring piece 16, so that sealing performance is further improved, to improve
The service life of three float-ball type aerators, later period failure rate is low, and maintenance cost is low.
In actual use, magneto 5 is run, and gas is generated in shell 6, by shaft 11 and upper housing 9 it
Between gap be emitted into chamber 25, and magneto 5 is being shut down, and after cooling, resorption can be generated in shell 6, at this point, in chamber 25
Gas can be back in shell 6, to reach a balance, if the gas in chamber 25 is inadequate, outside air passes through
Gap 24 enters chamber 25, to guarantee the amount of the resorption air after cooling of shell 6, due to the one third position of magneto 5
It sets on sea, so, water will not enter in motor, even if there is water entrance in gap 24, due to the air of 6 resorption of shell
It is most of from chamber 25, it is understood that there may be few portion of air come from the external world, so, the permanent magnetism of the utility model
Motor 5 must not have the case where water inlet when being applied to three float-ball type aerators.
Above to a kind of magneto provided by the utility model embodiment and its three floating balls with the magneto
Formula aerator is described in detail, and specific case used herein carries out the principles of the present invention and embodiment
It illustrates, the revealed technical solution of the utility model that the above embodiments are only used to help understand；Meanwhile for ability
The those skilled in the art in domain have change based on the idea of the present invention in specific embodiments and applications
Place, in conclusion the content of the present specification should not be construed as the limitation of the utility model.
