Description
Technical field: the utility model relates to a kind of deep-well pump, particularly a kind of Sewage deep well pump belongs to the plumbing mechanical field.
Background technique: Sewage deep well pump be a kind of be power with the motor, thereby drive the rotation of pump shaft impeller, phreatic water is got to the electronic deep-well pump on ground with centrifugal force.Present all kinds of submerged type pollution discharge pumps, when extracting fed sheet of a media, whole pump must be inserted in the fed sheet of a media, particularly when extracting mordant medium, because the problems such as material, sealing and insulating properties of pump self, cause water pump damage, working life to shorten easily, and the generation of situations such as people of getting killed of leaking electricity, and, keep in repair quite difficult in case appearance damages, and flow is generally less, is difficult to satisfy the needs of big flow.
Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Sewage deep well pump is provided, and it is simple in structure, compact, adopt the merogenesis dismounting, water-outlet quantity is big, high working efficiency, and do not need whole water pump inserted in the fed sheet of a media, can prolong the working life of pump.The utility model mainly comprises: filter screen, impeller base, impeller, the water flowing bearing support, nylon bearing, following tubular axis, water service pipe, long shaft-linking sleeve, base plate, outlet pipe, the motor undersetting, last tubular axis, the motor upper bracket, coupling, packing gland, bushed bearing, bearing, bearing gland, steel bushing, round nut, motor, the impeller fixed base, its Placement is: filter screen is connected with the impeller fixed base, impeller base is connected with the impeller fixed base, nylon bearing is connected with impeller base by hexagon socket head cap screw, following tubular axis passes nylon bearing, one end of following tubular axis is connected with impeller by locating stud, the other end is connected with last tubular axis by the internal thread of long shaft-linking sleeve, following tubular axis is connected with the inner ring of nylon bearing, the outer ring of nylon bearing is connected with the water flowing bearing support, last tubular axis passes packing gland, bearing, steel bushing, round nut, be connected with motor by coupling, bearing gland is connected with bearing, round nut is connected with last tubular axis, the upper end of motor upper bracket is connected with motor, the lower end is connected with the motor undersetting, the upper end of base plate is connected with the motor undersetting, the lower end is connected with deep well well head ground level by fang bolt, the water flowing bearing support is connected with the tube wall of water service pipe, filter screen, water service pipe, base plate, outlet pipe, the motor undersetting, the motor upper bracket, bushed bearing, motor all connects with form of flanges, and outlet pipe is arranged at motor undersetting one side.
During work, motor is placed in topmost, vertically insert pump in the fed sheet of a media, the degree of depth will guarantee that impeller immerses in the fed sheet of a media fully, by base plate whole pump is fixed on the deep water well head ground level, connect power supply, actuating motor, thereby tubular axis and tubular axis impeller rotation down in the drive, fed sheet of a media rotates through impeller, is admitted to water service pipe by action of centrifugal force, continuous rotation along with impeller, fed sheet of a media also constantly is admitted to water service pipe, and the water level of water service pipe constantly raises, and finally delivers to specific discharging place continuously through outlet pipe.But pump shaft starts 3.5 times of the torques of torque bearing pump own, can guarantee normal operation, positions such as each position tool withdrawal groove of pump shaft add all adopts circular arc excessive man-hour, and pump shaft and impeller are all done the dynamic balancing adjustment, the degree of unbalancedness of every fulcrum is at every meter 0.02, and the impeller degree of unbalancedness is 0.01.The Manufacturing material of Sewage deep well pump can be selected according to the character of actual fed medium, generally speaking, pump shaft all adopts stainless steel, characteristics are the intensity height, and are corrosion-resistant, and wear resistance is good, long service life, the multiple tracks bearing adopts lubricity and wear resistance nylon bearing preferably, and is not easy to wear, the life time that can prolong pump.If fed sheet of a media does not have specific (special) requirements to the material of pump, can select common materials such as carbon steel, cast steel, cast iron, spheroidal graphite cast iron for use as required, to reduce cost.
Sewage deep well pump is simple in structure, the dismounting of employing merogenesis, operation, easy maintenance, and bore is big, and water-outlet quantity per hour can reach the 1300-10000 ton, and lift can reach 3-12 rice, high working efficiency, and stronger suction capacity is arranged, and bottom valve need not be installed.In addition, impeller is that three single circle strings are curved leaf, pump seat, motor cabinet supports with four vertical rod skeletons, good stability, the degree of depth can also shorten or extend as required voluntarily, be suitable for the occasion of the interim change of the needs degree of depth, motor places the top of pump, separates with fed sheet of a media fully, so can avoid dielectric corrosion, the generation of the accident that can eliminate danger.
