Abstract
The utility model relates to a guide vane anti-rotation device which comprises an anti-rotation body cavity, four anti-rotation rib, an anti-rotation block, a bolt, a guide vane body and a seal ring. The guide vane anti-rotation device is characterized in that the anti-rotation block is fixedly connected with the guide vane body through the bolt, the four anti-rotation ribs are evenly distributed in the anti-rotation body cavity, and the seal ring is disposed between the guide vane body and the anti-rotation ribs. The guide vane anti-rotation device has the advantages that the anti-rotation ribs are matched with the anti-rotation block to effectively prevent the guide vane body from rotating; the anti-rotation block is connected with the guide vane body through the bolt, the anti-rotation block and the guide vane body can be demounted independently, and maintenance and replacement are facilitated; the guide vane anti-rotation device is simple in structure, convenient to use, safe and reliable.
Description
Technical field
The utility model relates to drainage machinery field, specifically a kind of stator anti-rotation device.
Background technique
Submersible pump refers to the pump of working environment below the water surface, it must be full of liquid in suction pipe and pump, after turn on pump before turn on pump, impeller High Rotation Speed, liquid wherein, along with blade rotates together, under the effect of centrifugal force, flies away from impeller and outwards penetrates, the liquid speed in pump case explosion chamber penetrating is slack-off gradually, pressure increases gradually, and then from pump discharge, discharge tube flows out.Now, around being thrown toward due to liquid, blade center forms the vacuum low-pressure district that not only there is no air but also there is no liquid, liquid in liquid pool is under the atmospheric effect of pond face, in suction pipe inflow pump, liquid is exactly so continuously from liquid pool, be pumped up and continuously from discharge tube, flow out.
Submersible pump unit is by: water pump, submersible motor (comprising cable), conduit pipe and control switch four is most of forms.Submersible pump is single-suction multilevel vertical centrifugal pump; Submersible motor is airtight water-filling wet type, vertical three-phase squirrel-cage induction motor, and motor is connected by pawl formula or singly-bound cartridge type coupling with water pump; The three core cable of different size is equipped with; Starting equipment is air-break switch and the self-coupling decompression air-operated apparatus of different capacitance grade, and the steel pipe that conduit pipe is different-diameter is made, and adopts flange to connect, and high-lift electric pump adopts gate valve control.
Stator great majority are used in the refluence situation in hydraulic machinery, the movable guide vane of picture water turbine, fixed guide vane, and the stator in water pump, because the stator Main Function in water pump is to control flow and form circular rector, therefore need to prevent that diffuser from freely rotating in water pump, also lack a kind of stator anti-rotation device that can play to stator anti-rotation effect at present.
Model utility content
The utility model, just for above technical problem, provides a kind of stator anti-rotation device that can play to stator anti-rotation effect.
The utility model is achieved through the following technical solutions.
A kind of stator anti-rotation device, comprise anti-rotation body cavity, anti-convulsion, Anti-rotary block, bolt, diffuser, seal ring, it is characterized in that being bolted between Anti-rotary block and diffuser, anti-convulsion is arranged in anti-rotation body cavity, between diffuser and anti-convulsion, seal ring is set.In anti-rotation body cavity, be evenly distributed with four anti-convulsions.
Anti-convulsion described in the utility model coordinates Anti-rotary block, effectively prevents the rotation of stator, and be bolted between Anti-rotary block and diffuser by four anti-convulsions, can dismantle separately, is conducive to inspect and change.
This stator anti-rotation device is simple in structure, easy to use, safe and reliable.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
1-anti-rotation body cavity, 2-anti-convulsion, 3-Anti-rotary block, 4-bolt, 5-diffuser, 6-seal ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of stator anti-rotation device, comprise anti-rotation body cavity 1, anti-convulsion 2, Anti-rotary block 3, bolt 4, diffuser 5, seal ring 6, it is characterized in that by bolt 4, fixing between Anti-rotary block 3 and diffuser 5, anti-convulsion 2 is arranged in anti-rotation body cavity 1, between diffuser 5 and anti-convulsion 2, seal ring 6 is set.In anti-rotation body cavity 1, be evenly distributed with four anti-convulsions 2.
Anti-convulsion 2 described in the utility model coordinates Anti-rotary block 3, effectively prevents the rotation of diffuser 5 by four anti-convulsions 2, and by bolt 4, is connected between Anti-rotary block 3 and diffuser 5, can dismantle separately, is conducive to inspect and change.
This stator anti-rotation device is simple in structure, easy to use, safe and reliable.
Claims (2)
1. a stator anti-rotation device, comprise anti-rotation body cavity, anti-convulsion, Anti-rotary block, bolt, diffuser, seal ring, it is characterized in that being bolted between Anti-rotary block and diffuser, anti-convulsion is arranged in anti-rotation body cavity, between diffuser and anti-convulsion, seal ring is set.
2. a kind of stator anti-rotation device according to claim 1, is characterized in that being evenly distributed with in described anti-rotation body cavity four anti-convulsions.
