Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of deep well pump, the sealing in more particularly to a kind of deep well pump
Structure.
Background technology
Deep well pump is that motor and water pump direct-connected integrated pull the plug the water lift equipment of work, has simple in construction, unit effect
Rate is high, and noise is small, safe and reliable to operation, it is convenient to install and maintain the advantages of.Must be hydraulically full in suction line and pump before turn on pump, open
Impeller rotates at a high speed after pump, and liquid therein rotates, under the influence of centrifugal force, flies away from impeller and outwards penetrate together with blade
Going out, the liquid of the injection speed in pump case diffuser casing is gradually slack-off, and pressure gradually increases, and is then flowed out from pump discharge discharge pipe,
Both vacuum low-pressure areas without air without liquid now are formed because liquid is thrown toward surrounding at blade center, liquid pool
In liquid flow into pump in the presence of the atmospheric pressure of pond face.The motor shaft in deep well pump is typically prevented by mechanical seal at present
Only liquid enters pump body, but traditional sealing structure only realizes sealing by the cooperation of stationary ring and rotating ring, therefore close
It is poor to seal effect, because deep well pump is motor and water pump direct-connected integrated pulls the plug work, sealing structure is once damaging directly to lead
It is bad to send a telegraph machine burning.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided a kind of performance is more stable
And the sealing structure in the more preferable deep well pump of sealing effectiveness.
The purpose of this utility model can be realized by following technical proposal：A kind of sealing structure in deep well pump, including
Seal receptacle, motor shaft and it is arranged at motor shaft Upper shaft sleeve, it is characterised in that rotating seat, dynamic is disposed with described axle sleeve
Ring, stationary ring and stationary seat, throw-out collar is provided with described stationary seat, flow guide sleeve is provided with described seal receptacle, described pushes away
Spring is provided between ring and flow guide sleeve, gland is provided with described seal receptacle, is set between described gland and flow guide sleeve
There is the stop pin for preventing that flow guide sleeve from rotating.
Sealing structure its technique effect in this deep well pump is：Throw-out collar is made by rotating seat, rotating ring, quiet by the elastic force of spring
Ring and stationary seat extruding are arranged in axle sleeve, to realize sealing effectiveness, and mechanical seal can be made to form an overall structure more
It is more preferable to step up to gather sealing effectiveness, after stationary ring and rotating ring are lost because of friction, due to passing through spring compression, spring production between the two
Raw axial elastic force makes stationary ring and rotating ring remain and be brought into close contact, and flow guide sleeve is wherein provided with seal receptacle, will by screw
Gland is connected with seal receptacle and flow guide sleeve is fixed in seal receptacle, and stop pin is provided between gland and flow guide sleeve, by anti-
Shipping and reselling on another market can prevent flow guide sleeve rotation from making its performance more stable.
In sealing structure in a kind of above-mentioned deep well pump, sealing ring is provided between described rotating seat and axle sleeve.
In sealing structure in a kind of above-mentioned deep well pump, drive ring is provided with above the gland.
In sealing structure in a kind of above-mentioned deep well pump, O is provided with the contact surface of described flow guide sleeve and gland
Type circle one.
In sealing structure in a kind of above-mentioned deep well pump, O is provided with the contact surface of described seal receptacle and gland
Type circle two.
Compared with prior art, the sealing structure in this deep well pump to the improvement in tradition machinery sealing structure by making it
It is more stable with performance and the advantages of sealing effectiveness is more preferable.
