Description
Technical Field
The utility model relates to a mechanical equipment maintains technical field, concretely relates to multistage centrifugal pump shaft coupling dismounting device.
Background
Because the power plant is long-time, the overload operation, the pump internals can appear in the boiler feed pump damages, when dismantling, must tear the shaft coupling open earlier, and the shaft coupling is interference fit with the pump shaft, and the shaft coupling can be followed the pump shaft and dismantled after needing the heating. Because the shaft coupling excircle variation in size of the multistage centrifugal pump of different models, the commonality of current dismounting device is not enough, and its material is high temperature resistant, yielding during the heating, the fracture, and life is not long, still has its claw that is used for fixing in addition and scratches the condition of shaft coupling.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that the difficulty is dismantled with the pump shaft to the shaft coupling, and pump shaft and shaft coupling are damaged, dismantle inconvenient, waste time and energy, for solving above-mentioned problem, the utility model provides a multistage centrifugal pump shaft coupling dismounting device.
The purpose of the utility model is realized with the following mode:
the utility model provides a multistage centrifugal pump shaft coupling dismounting device, includes the screw thread section of thick bamboo through hydraulic pressure joint connection hydraulic pressure station, screw thread section of thick bamboo one end threaded connection dismantles the dish, and the hydraulic pressure joint is connected to the screw thread section of thick bamboo other end, be equipped with the removal piston in the screw thread section of thick bamboo, the one end that the removal piston is close to hydraulic pressure joint is equipped with a plurality of seal groove, is equipped with O type sealing washer in the seal groove, is equipped with the long banding hole of dismantling of.
At least two sealing grooves are formed.
And a hanging ring is arranged on the outermost side of the disassembling disc and is in threaded connection with the disassembling disc.
The disassembling disc is provided with at least three strip-shaped disassembling holes, the disassembling holes are distributed in the radial direction, and the included angle between every two adjacent disassembling holes is equal.
The threaded cylinder, the movable piston and the disassembling disc are all made of 40 Cr.
Compared with the prior art, the utility model discloses can be through demolising a set and a screw thread section of thick bamboo, ensure that pump shaft and shaft coupling are not damaged, dismantle convenient and fast, labour saving and time saving improves work efficiency, the utility model discloses fall, collision back non-deformable, high temperature resistant, heating cooling back non-deformable, increase of service life.
