Embodiment:
The utility model comprises motor 1, well head fixed base, the spiral shell pump housing, delivery pipe, main spindle coupling, it is characterized in that: motor 1 is non-submersible motor, and upward, delivery pipe is divided into outer flexible tube 6 and inner flexible tube 4 to the axle head of the spiral shell pump housing; Separately be provided with soft or hard axle coupling, soft or hard axle coupling is sleeve-like, and its endoporus is half unthreaded hole, half interior threaded hole; Be provided with a gap bridge axis body be made up of lower pipe box 11, Upper shaft sleeve body 8, rib 7, stiff shaft 14, lower flexible axle 10, the Upper shaft sleeve body 8 underpart fit of the sleeve-like of gap bridge axis body fixes a step cover 9, step overlaps fluting on 9 inner round wall and is provided with seal ring, Upper shaft sleeve body 8 inwall also fit fixes the bearing at two intervals, a dynamic step that fits through of stiff shaft 14 overlaps 9, its stage casing stationary fit is through two bearings, the two end part of stiff shaft 14 are provided with outside thread, and on stiff shaft 14 epimere outside thread, the locking nut of fit is by two bearing lockings; Stiff shaft 14 lower end thread spindle screws up in the tapped hole being fixed on a meta soft or hard axle coupling also with nut check, on lower flexible axle 10, axle head is tightly fixed and is linked in meta soft or hard axle coupling unthreaded hole, the underpart 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 coupling, and lower flexible axle 10 naked section is coated with rubber sheath 13; Upper shaft sleeve body 8 epimere step cylindrical is provided with outside thread, the upper end portion even distribution type of four ribs 7 welds with Upper shaft sleeve body 8 hypomere cylindrical, the underpart of four ribs 7 is welded on the epimere cylindrical of lower pipe box 11, and the outside thread of lower pipe box 11 hypomere screws up in the internal 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 coupling, inner flexible tube 4 underpart inner circle screw up be fixed on Upper shaft sleeve body 8 epimere outside thread on implement sealed type connect, outer flexible tube 6 is in outside inner flexible tube 4, rear and lower end portion, four the rib 7 outers drive 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 end-hole screws up sealed type on the outside thread of a three-way body 3 longitudinal pipe lower nozzle and connects; Upper cover 2 is circle ring disk periphery downward disjunctor tubular casing, the internal thread of tubular casing screw up to overlay in three-way body 3 upper end-hole outside thread and by the upper seal ring elasticity of a trapezoidal cross-section three-way body 3 upper end-hole end face, upper cover 2 inwall, through on seal ring inner circle inner flexible tube 4 outer wall, inner flexible tube 4 upper end-hole is in plane on upper cover 2 central hole; Motor 1 main shaft is implemented to be connected with the upper end-hole of upper flexible axle 5 by main spindle coupling, and motor 1, three-way body 3 are separately fixed on well head fixed base.
Well depth can 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 the flexible axle cylindrical total length of tens meters long is exposed, soaked, all will implement bag and paste rubber sheath 13.The long bag of length pastes technology difficulty greatly, as long as sheath position immersion, then total length immersion easily rust, the flexible axle life-span is short.The object arranging gap bridge axis body is: as long as the short a few centimeter length bags of lower flexible axle 10 paste sheaths, and the upper flexible axle 5 of tens meters long protect by inner flexible tube 4 and need not wrap subsides 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 the fixing laminating of sealed type when rigidity outside thread.
Motor 1, three-way body 3 are in above well head respectively.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 floods at the lower sky of bridge shaft object table rank cover 9; the seal ring of step cover 9 protects gap bridge axis body inner bearing and does not soak; the spatial channel at rib 7 interval between outer flexible tube 6 and Upper shaft sleeve body 8 rises for current; after water has crossed upper axis body 8; then enter three-way body 3 by the runner between outer flexible tube 6, inner flexible tube 4; inner flexible tube 4 upper end-hole aerial in three-way body 3 is surrounded by upper seal ring, and water can only be discharged 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 wire soft shaft, 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 consumpiton is large and waste energy, and even accidents caused, motor 1 of the present invention be non-submersible motor, and use common electric machine, does not exist this problem, then relatively energy-conservation.
