The utility model discloses well is with complete sets of submerged motor pump application coupler, its characterized in that: is prepared from the following components: the coupler comprises a hoisting support, a sling chain, a guide pillar, a water outlet pipe, a coupler, a water outlet elbow, an electric pump and a fixed support, wherein the main body of the coupler is arranged on the fixed support, and the outlet of the coupler is connected with the water outlet pipe through a flange; the hanging plate of the coupler is arranged at the front end of the water outlet elbow, and the front end of the water outlet elbow is fixedly connected with an outlet flange of the electric pump; the coupler is provided with two guide pillars, the lower ends of the guide pillars are matched with two bosses of the coupler, and the upper ends of the guide pillars are fixed on the side wall of the access hole; the sling extends out of a winch on the hoisting bracket, and the lifting hook is fixedly connected with a hoisting hole of the water outlet elbow; the lower end of the hanging chain is connected with the other hoisting hole of the water outlet elbow.

The utility model discloses, have characteristics such as reasonable in design, simple structure, easily processing assembly, low in manufacturing cost has avoided the overweight charge pump of carry, leads to the coupler to appear fatigue damage in the wedge claw position, causes the accident loss.

Drawings

FIG. 1 is a schematic diagram of a well submersible pump coupler assembly;

in the figure: 1 is a hoisting support, 2 is a sling, 3 is a sling chain, 4 is a guide post, 5 is a water outlet pipe, 6 is a coupler, 7 is a water outlet elbow, 8 is an electric pump, and 9 is a fixed support.

Detailed Description

The complete equipment of the coupler applied by the submersible electric pump for the well is realized in the way, and the following description is specifically made by combining the attached drawings.

See fig. 1, the utility model discloses well submersible pump uses integrated equipment of coupler is by: the device comprises a hoisting support 1, a sling 2, a sling 3, a guide pillar 4, a water outlet pipe 5, a coupler 6, a water outlet elbow 7, an electric pump 8 and a fixed support 9, wherein the main body of the coupler 6 is arranged on the fixed support 9, and the outlet of the coupler is connected with the water outlet pipe 5 through a flange; the hanging plate of the coupler 6 is arranged at the front end of the water outlet elbow 7, and the front end of the water outlet elbow 7 is fixedly connected with an outlet flange of the electric pump 8. Two guide pillars 4 are arranged, the lower ends of the guide pillars 4 are matched with two bosses of the coupler 6, and the upper ends of the guide pillars 4 are fixed on the side wall of the access hole. The sling 2 extends out from a winch on the hoisting bracket 1, and the lifting hook is fixedly connected with a hoisting hole of the water outlet elbow 7. The lower end of the sling chain 3 is connected with the other hoisting hole of the water outlet elbow 7, and plays an auxiliary role in the installation and hoisting process.

When the coupler is installed, the sling 2 slowly extends out of the winch on the hoisting support 1, and the hanging plate of the coupler 6 slowly slides downwards along the guide pillar until the hanging plate of the coupler 6 is attached to the main body. The lifting process is opposite to the lifting process.

The utility model discloses the complete sets of coupler is used to well submerged motor pump, in implementation process, need through moment formula M = F L, calculates the axial length size of outlet elbow 7. The specific principle is as follows: in the running process of the electric pump 8, the reaction force F generated by the lift is smaller than the pre-tightening pressure N generated by the weight of the electric pump 8 between the main body of the coupler 6 and the binding surface of the hanging plate through the force arm, so that the hydraulic performance of the electric pump 8 is ensured to be exerted, if F is larger than N, when the electric pump 8 runs, a large amount of leakage can be generated between the main body of the coupler 6 and the binding surface of the hanging plate, and the use requirement of a user can not be met. Meanwhile, the material and the structural performance of the coupler 6 are also considered, so that the phenomenon that the coupler 6 is fatigue-damaged at the wedge claw position to cause accident loss due to the fact that an overweight electric pump is mounted is avoided.

The utility model discloses, have characteristics such as reasonable in design, simple structure, easily processing assembly, low in manufacturing cost has avoided the overweight charge pump of carry, leads to the coupler to appear fatigue damage in the wedge claw position, causes the accident loss.
