Description
Technical Field
The utility model relates to a dismouting device especially relates to a dismouting device that is used for nuclear power plant owner to feed pump rotational speed device.
Background
At present in the dismouting adjustment process of main feed pump rotational speed device, the universal tool that the market was purchased that commonly uses combines actual installation characteristics, has following practical problem:
(1) the installation space of the measuring device is generally narrow, the geometric dimension of the general tool cannot be adapted, and the assembly, disassembly and adjustment are time-consuming and labor-consuming.
(2) The measuring device has small and exquisite and precise structure, the overall dimension of the general tool can not be accurately matched, and the measuring device is easy to damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dismouting device that is used for nuclear power plant owner's water-feeding pump rotational speed device in order to overcome the defect that above-mentioned prior art exists.
The purpose of the utility model can be realized through the following technical scheme:
the utility model provides a dismouting device that is used for nuclear power plant owner to feed water pump rotational speed device, includes the handle, the one end of handle is equipped with the wrench head, the other end of handle is equipped with the hanging hole.
Furthermore, the wrench head is provided with a thread groove.
Further, the opening width of the thread groove is 8mm
Further, the opening thickness of the thread groove is 2.5 mm.
Further, the length of the handle is 100 mm.
Further, the wrench head and one end of the handle are integrally formed.
Further, the opening shape of the thread groove is hexagonal.
Furthermore, the wrench head and the handle are respectively made of titanium alloy or alloy steel.
Compared with the prior art, the utility model has the advantages of it is following:
1) work efficiency is high, and the thickness design accurate adjustment of novel spanner is convenient, and is more laborsaving, and the installation technology and the installation rate have been powerfully guaranteed, compare and use traditional universal tool, can save operating time more than 90%.
2) Considering that the disassembly and assembly speed of the thermal control equipment directly influences the maintenance progress of the main water feeding pump body, the pre-tightening force of the re-assembly equipment can be guaranteed to meet the design requirement.
3) Equipment damages the injury risk and is lower, and factor of safety is high: compared with the method that a universal tool is used for disassembling and assembling the probe of the main feed pump rotating speed device, the method is safer and more reliable.
4) Simple and convenient operation, low cost and repeated use.
