Detailed description of the invention:
The present invention includes motor 1, the fixing seat of well head, the spiral shell pump housing, conveying pipe, main spindle coupling, it is characterised in that: motor 1 is non-submersible motor, and upward, conveying pipe is divided into outer flexible tube 6 and inner flexible tube 4 to the axle head of the spiral shell pump housing；Being additionally provided with soft or hard axle shaft coupling, soft or hard axle shaft coupling is sleeve-like, and its endoporus is half unthreaded hole, half internal thread hole；It is provided with a gap bridge axis body being made up of lower pipe box 11, upper shaft body 8, rib 7, stiff shaft 14, lower flexible axle 10, the upper shaft body 8 bottom fit of the sleeve-like of gap bridge axis body fixes a step set 9, step overlaps fluting on 9 inner round wall and is provided with sealing ring, upper shaft body 8 inwall also fit fixes the bearing at two intervals, a piece dynamic step that fits through of stiff shaft 14 overlaps 9, its stage casing stationary fit two bearings of traverse, the both ends of stiff shaft 14 are provided with external screw thread, and on stiff shaft 14 epimere external screw thread, the locking nut of fit is by two bearing lockings；Stiff shaft 14 lower end thread spindle screws up in the screwed hole being fixed in position soft or hard axle shaft coupling and with nut check, on lower flexible axle 10, axle head is tightly fixed and is linked in the soft or hard axle shaft coupling unthreaded hole of middle position, the bottom of lower flexible axle 10 implements to be connected with the upper external thread of shaft end of the spiral shell pump housing by the next soft or hard axle shaft coupling, and lower flexible axle 10 naked section is coated with rubber sheath 13；Upper shaft body 8 epimere step cylindrical is provided with external screw thread, the upper end even distribution type of four ribs 7 welds with upper shaft body 8 hypomere cylindrical, the bottom of four ribs 7 is welded on the epimere cylindrical of lower pipe box 11, and the external screw thread of lower pipe box 11 hypomere screws up in the female thread of spiral shell pump housing pump case pipe 12 upper end；Upper flexible axle 5 is implemented to be connected with stiff shaft 14 upper shaft by upper soft or hard axle shaft coupling, inner flexible tube 4 bottom inner circle screws up implements sealed connection on the external screw thread being fixed on upper shaft body 8 epimere, outer flexible tube 6 is in outside inner flexible tube 4, posterior end portion, four the rib 7 outers tight fit of outer flexible tube 6 hypomere inner circle fit gap bridge axis body is enclosed within pump case pipe 12 epimere cylindrical, and outer flexible tube 6 upper port screws up sealed connection on the external screw thread of a three-way body 3 longitudinal pipe lower nozzle；Upper cover 2 is circle ring disk periphery one tubular casing of downward disjunctor, the female thread of tubular casing screw up in three-way body 3 upper port external screw thread and the upper sealing ring elasticity of a trapezoidal cross-section is overlayed three-way body 3 upper port end face, upper cover 2 inwall, through on sealing ring inner circle inner flexible tube 4 outer wall, inner flexible tube 4 upper port is in plane on upper cover 2 medium pore；Motor 1 main shaft is implemented to be connected with the upper port of upper flexible axle 5 by main spindle coupling, and motor 1, three-way body 3 are separately fixed on the fixing seat of well head.
Well depth may be up to tens meters, if a flexible axle directly docks with well head motor 1 main shaft, shaft bottom spiral shell pump housing axle head, then tens meters long flexible axle cylindrical total length is exposed, soaked, will implement bag patch rubber sheath 13.Length long bag patch technology difficulty is big, as long as one position immersion of sheath, then total length immersion easily rust, the flexible axle life-span is short.The purpose arranging gap bridge axis body is in that: if a few centimeter length bags patch sheath that lower flexible axle 10 is short, and the upper flexible axle 5 of tens meters long is protected by inner flexible tube 4 and need not be wrapped patch sheath.That gap bridge axis body is inner flexible tube 4 simultaneously is easy for installation, keep away water-stop provides structural condition.
Outer flexible tube 6, inner flexible tube 4 are plastic tube, and its plasticity makes it screw up can sealed fixing laminating when rigidity external screw thread.
Motor 1, three-way body 3 are respectively at above well head.Motor 1 main shaft drives spiral shell pump housing axle head to rotate by upper flexible axle 5, stiff shaft 14, lower flexible axle 10; the water that the spiral shell pump housing pumps overlaps the lower sky of 9 and floods on bridge shaft object table rank; the sealing ring of step set 9 protects bearing in bridge shaft body and does not soak; the spatial channel at rib 7 interval between outer flexible tube 6 and upper shaft body 8 rises for current; after water has crossed upper axis body 8; then entered three-way body 3 by the runner between outer flexible tube 6, inner flexible tube 4; inner flexible tube 4 upper port aerial in three-way body 3 is surrounded by upper sealing ring, makes water can only discharge from the side runner of three-way body 3.Inner flexible tube 4 plays a part upper flexible axle 5 and water segregation.Flexible axle is conventional products, is a kind of Bowden cable, flexible, thus whole piece flexible axle coordinate inner flexible tube 4, outer flexible tube 6 can coiling agglomerating, convenient transportation and lightweight.
When prior art submerged pump when water leakage, electric leakage, power consumption is big and wastes the energy, and even accidents caused, motor 1 of the present invention is non-submersible motor, uses common electric machine, is absent from this problem, then relatively energy-conservation.
