Description

A kind of vertical anticlogging immersible pump
Technical field
The present invention relates to immersible pump field, specifically refer to a kind of vertical anticlogging immersible pump.
Background technology
Immersible pump is the visual plant of deep-well water lift.During use, whole unit pulls the plug work.Subsoil water is extracted Earth's surface is domestic water, speedily carry out rescue work in mine, industry cools down, field irrigation, seawater lift, steamer adjust carry, it may also be used for fountain scape Seeing, hot water immersible pump is used for hot spring bathing, could be applicable to extract subsoil water from deep-well it can also be used to river, reservoir, water channel Deng water lift engineering.It is mainly used in field irrigation and alpine region people and animals' water, is also available for central air-conditioning cooling, source pump, cold pump Unit, city, factory, railway, mine, building site draining use.
Immersible pump technology maturation, use on existing market are reliable, but when the underwater environment that mud is more or aobvious Obtain somewhat unable to do what one wishes, still cannot enter the pump housing, life-time service from bottom along current by the substantial amounts of mud of rejection all the time, go back It is the inside of immersible pump to be impacted, reduction of service life.The mire that particularly some mud packing ratios are thicker, owing to entering Mud is pressed close at the mouth of a river, immersible pump just brings into operation when, can be picked up by substantial amounts of mud in bottom, simultaneously also can be with very Many sandstone or strip twister enter immersible pump, once bulk deposition or enwind impeller and motor can be caused damage.And And the bearing coordinated with power transmission shaft in existing immersible pump mostly uses rolling bearing, if equipment high speed for a long time is transported Turning, the long-time contact with power transmission shaft of rolling bearing easily causes abrasion.
Summary of the invention
It is an object of the invention to provide and a kind of can intercept the vertical anti-of sandstone, cutting twister and the design of floated axle The immersible pump of blocking.
The present invention is achieved through the following technical solutions: a kind of vertical anticlogging immersible pump, including passing sequentially through bolt even Top shell, electric machine casing, oil sealing cavity and the wheel cavity connect, is provided with motor, the transmission on described motor in described electric machine casing Axle through oil sealing cavity and coordinates with the impeller being provided with in wheel cavity, and described wheel cavity is communicated with lifting pipe, wheel cavity Bottom is bolted the water inlet base connected with wheel cavity, and described water inlet base is provided with zinc-plated gauze, intakes at the end The rotor being connected with impeller axle it is additionally provided with in Zuo.
Described electric machine casing, oil sealing cavity all connect with wheel cavity, and the power transmission shaft on described motor runs through oil sealing cavity And penetrate in wheel cavity then, and being marked with machine oil in oil sealing cavity, machine oil plays lubrication by contacting with power transmission shaft and seals Effect, and be equipped with sealing member at oil sealing cavity both ends open to ensure that the muddy water in wheel cavity will not be entered by space Electric machine casing, in order to avoid motor damage.And it is provided with, in the water inlet base of wheel cavity bottom, the rotor being connected with impeller concentric shafts It is the blockage resisting ability in order to strengthen equipment, by the drive of power transmission shaft, rotor is worked with impeller simultaneously, and rotor is at a high speed Rotate and the twister in the muddy water that water inlet base enters can be cut off, it is to avoid impeller is wound and causes motor damage Problem.And being provided with zinc-plated gauze at water inlet chassis interior is the effect playing primary filter, zinc-plated material can provide fine Resistance to corrosion, and zinc-plated gauze can utilize the silt and sandstone that less aperture came in drainage, prevents bigger stone Head damages the impeller of high-speed rotation in entering wheel cavity.The whole process drawn water and principle are prior art, at this no longer Repeat.
