Description
Technical field
The utility model relates to a kind of agricultural irrigation equipment, specifically a kind of flexible axle irrigation pump.
Background technique
Flexible axle pump in the market be a kind of pump head under water, power is connected on the drive wheel of motor on the road surface or motor, the centre utilizes the flexible axle transmission of vibrating head principle to come a kind of submersible pump of transmission, on the one distolateral wall of pump case water intake is arranged, the other end sidewall is provided with a water outlet, connect upward draining with the straight tube of binding water pipe, bearing seal is rubber seal, because of water outlet on the sidewall of pump case, just with the 90 degree dead angles that are directed to of impeller water outlet, water pump is when working like this, and water will be flushed on the pump wall according to the guiding of impeller, return at sidewall and get rid of, the resistance that has strengthened water has like this consumed part power.The bearing waterproof adopts rubber water sealing, water seal directly and the pump shaft friction, rubber water sealing damages very soon under the background of different temperatures different quality, is easy to just enter into bearing chamber through the one section water that rubs, it is bad that bearing length is corroded.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of flexible axle irrigation pump is provided, the technological scheme that its technical problem that solves the utility model adopts is: structure of the present utility model comprises pump case, impeller, bearing bracket, elbow, bearing, water pump spindle, the water inlet protective housing, mechanical seal, sealing gland, the flexible axle connecting head, line shaft, flexible pipe, flexible axle, motive power wheel, it is characterized in that water pump spindle is arranged in the sealing gland, water pump spindle is provided with two bearings, between the outer end of bearing water pump spindle and sealing gland, be provided with mechanical seal, one end of water pump spindle is provided with impeller, impeller is half-opened impeller, impeller is screwed on the water pump spindle by the dextrorotation button, impeller is arranged in the pump case, pump case and sealing gland joint are provided with seal ring, the pump case of impeller outer end is provided with into water protective housing, on the pump case of impeller one side opening is set, the pump case opening of impeller one side is connected with elbow, be provided with flexible axle in the flexible pipe, the two ends of flexible axle are provided with the flexible axle connecting head, the flexible axle connecting head of one end is inserted in the water pump spindle and by nut and is connected with water pump spindle, the flexible axle connecting head of the other end is inserted in the line shaft and by nut and is connected with line shaft, line shaft is arranged in the bearing bracket, also be provided with bearing between line shaft and the bearing bracket, the outer end of line shaft is connected with motive power wheel.
The utility model is in order to reduce the resistance of water, the pump case of flexible axle irrigation pump is adopted the scroll casing type design, water outlet is designed in the direction downstream of blade guiding, elbow of recycling comes to change arbitrarily as required the direction of water outlet, can also be as required different flows is selected the elbow of different bores, bearing seal adopts mechanical seal of the interior installation of bearing chamber to come waterproof, the little and long service life of frictional force.Working principle: drive line shaft by motive power wheel and rotate, rotate thereby the rotation of line shaft rotation drive flexible axle drives water pump spindle, the water pump spindle rotation is discharged the rotation of impeller with the underground water of extraction by the rotation of impeller through bend pipe.
The beneficial effects of the utility model are, the utility model elbow weep hole is arranged on the pump case sidewall of direction downstream, the resistance of water and the frictional force of sealing have been reduced greatly, give full play to machine power, and can change drainage direction arbitrarily according to needs very much, be a kind of be the energy-conservation convenient mechanical facilities of irrigation and drainage that use again.
