Abstract
The utility model relates to a deep well water pump with a flexible shaft, comprising a swing pipe, a flexible shaft, a water pump body and a water delivery flexible pipe. The utility model is characterized in that a retractable support frame which can position the water pump body on a well wall is arranged below the water pump body, the water outlet of the water pump body is far away from an impeller, the water outlet is connected with the water delivery flexible pipe at a position except the maximum diameter of the impeller; the water delivery flexible pipe is provided with an elbow which can reduce the impact of water flow in the pipe at the turning of a well head, the casing of the elbow is fixed at the position of the well head, and the swing pipe is a lengthened wear resistant casing pipe for the flexible shaft. The pump with the structure can reduce the rotating vibration of the flexible shaft in the swing pipe; the utility model has the advantages of long service life, convenient installation and pulling out, and safe working.
Description
The utility model relates to a kind of improved flexible axle deep well water pump.
China Patent No. is that 92202978.4 " flexible axle dive under water centrifugal agricultural clean waterpump " discloses a kind of water pump, it is characterized in that a flexible axle is arranged in the water pump swing pipe, the lower end links to each other with the water pump vane transmission shaft, the upper end links to each other with power, water pump directly pulls the plug, effluent pipe mouth is towards the well head direction, connect by water delivery hose,, directly hang because of water pump and pull the plug though this pump has solved the field irrigation problem of low water level area and areas without electricity, flexible axle rotates in swing pipe, produce violent trip and shake, because an effluent pipe mouth part is above the impeller of pump, the impact of water is big to the impeller influence in the outlet pipe, the shake of impeller is rotated flexible axle in swing pipe, the You Zhengeng that produces is violent, swing pipe easy to wear, even can rub swing pipe, water pump is fallen in the well, caused very big economic loss.
Task of the present utility model provides a kind of minimizing flexible axle and changes the line of production in the swing pipe inward turning and give birth to violent trip and shake the flexible axle deep well water pump of long service life.
Task of the present utility model is finished as follows: this flexible axle deep well water pump includes swing pipe, flexible axle, water pump body and water delivery hose, it is characterized in that: the retractable supporting frame that makes it to locate on the borehole wall is arranged under the water pump body, the water outlet of water pump body away from impeller on the position outside the impeller maximum diameter, water outlet connects water delivery hose, water delivery hose has its housing to be fixed on the elbow that the reduced in-pipe flow on the pithead position impacts at the well head turning, swing pipe is the wear-resisting flexible axle sleeve pipe of a lengthening.
The utility model is not depended merely on and is hung the water pump body location, because the supporting frame effect is arranged, reduce the vibration of water pump body, the outlet of water pump body is away from impeller in addition, the effect of well head place, water delivery hose top elbow, and the impact force of water is to the ill-effect of impeller when having reduced water delivery, weaken the bladed disk vibration that the impact because of water causes, and the trip that flexible axle is rotated in the swing pipe attenuating of shaking prolongs its working life, and installs and extract simple and convenient.Swing pipe adopts the wear-resisting flexible axle sleeve pipe of the lengthening of a Gent system, and wear resistance is good, and frictional force is little; can protect flexible axle effectively, and then also have energy-conserving action, no interface in the middle of this swing pipe; anti-sealing goes into to wash away lubricant oil in the pipe, reduces the wearing and tearing of water pump body inner bearing, makes this pump work safe and reliable.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the longitudinal profile schematic representation of the flexible axle deep well water pump that provides of the utility model;
In Fig. 1,1, flexible axle, 2, swing pipe, 3, water pump body, 4, impeller, 5, supporting frame, 6, water outlet, 7, water delivery hose, 8, elbow.
Flexible axle 1 and swing pipe 2 are hung water pump body 3 and are pulled the plug during installation, supporting frame 5 is located water pump body 3 by the borehole wall, water pump body when work vibration is reduced, and the water outlet 6 of water pump body 3 is away from impeller 4, the effect of the elbow 8 at well head place, water delivery hose 7 top, weaken the vibration of the impeller 4 that the impact because of water delivery causes, swing pipe adopts the oscillating column pump flexible axle sleeve pipe of a lengthening, because these 4 improvement, makes flexible axle 1 in the living violent trip minimizing of shaking of changing the line of production of swing pipe 2 inward turnings, the work peace is reliable, long service life.
