This neotype effect is: the novel pump has the advantages that maintenance personnel are reduced, force is uniformly applied when the pump is maintained, and the completeness of two ends and end covers of the pump is guaranteed. And the maintenance rate of the submersible pump is improved.

Description

Special cross wrench for submersible pump maintenance

Technical Field

The utility model belongs to special spanner, concretely relates to immersible pump maintenance cross special spanner.

Background

In-situ leaching mining, deep water submersible pumps are used in a liquid pumping well, the Guerz 8GS55A and 8GS75A submersible pumps used in our factory are used, and more than 500 deep water submersible pumps are maintained every year. In the past, when the submersible pump is maintained, the end covers at two ends of the submersible pump are disassembled by using pipe tongs and iron bars. The stress of the end cover of the pump is not uniform when the pipe tongs and the iron bar are used for disassembling the end cover, and the two ends of the pump in the past have problems. Both ends of the pump and the end cover are deformed under the condition of uneven external force. The two ends of the pump and the end cover can not be tightly combined, and the pump to be maintained is an unqualified submersible pump. After the submersible pump is used, the labor cost and the production cost are increased.

Novel content

This novel defect to prior art provides a immersible pump maintenance cross special spanner.

This is novel to realize like this: a special spanner for repairing a submersible pump cross comprises a base frame assembly, a handle assembly and a spanner tooth assembly, wherein the handle assembly is used for applying force from the outside, and the spanner tooth assembly is used for applying force to a target nut or screw.

The wrench special for repairing the submersible pump cross is characterized in that the base frame component is a base frame with a circular outer profile.

The wrench special for repairing the submersible pump cross is characterized in that the handle assembly is a force rod arranged on the base frame.

The wrench for repairing a submersible pump cross as described above, wherein the force rod extends outwardly from the sidewall of the base frame.

The wrench special for repairing the submersible pump cross is characterized in that the wrench comprises four force rods which are uniformly distributed on the side wall of the base frame.

The wrench special for repairing the submersible pump cross is characterized in that the wrench tooth component is a wrench tooth arranged at the center of the base frame.

The special spanner for repairing the cross for the submersible pump is characterized in that the spanner comprises four spanner teeth which are uniformly arranged on the base frame.

This neotype effect is: the novel pump has the advantages that maintenance personnel are reduced, force is uniformly applied when the pump is maintained, and the completeness of two ends and end covers of the pump is guaranteed. And the maintenance rate of the submersible pump is improved.

Drawings

Fig. 1 is a schematic view of a maintenance device for a motor of a submersible pump.

Fig. 2 is a right side view of fig. 1.

In the figure: 1 a base frame; 2, a force rod; 3, wrenching teeth.

Detailed Description

1 principle of operation

As shown in figure 1, the force rod and the wrench tooth are fixed on the base frame to form a whole. The force rod and the wrench tooth are vertical and symmetrical. The wrench teeth are inserted into 4 holes of the end covers by utilizing 4 holes of the end covers at the two ends of the submersible pump, and the holes are just matched. The maintenance personnel grasp two of the force rods to form diagonal force. The uniform force ensures the integrity of the end caps of the submersible pump and both ends of the submersible pump.

2 procedure

The shell of the submersible pump is fixed on a maintenance platform, and the plate teeth are sleeved according to the upper hole of the end cover of the submersible pump and are tightly attached to the end cover. The maintenance personnel hold two of the force rods, rotate in the anticlockwise direction, and loosen the end covers to disassemble the submersible pump. And rotating the end cover clockwise to assemble the submersible pump.
