Extraction and penetration method of rotor of rail-guided hydraulic feeding power generator

Abstract

The invention discloses an extraction and penetration method of a rotor of a rail-guided hydraulic feeding power generator. The method comprises the steps of arranging a first support and a second support which are movable at the two ends of the rotor, arranging a rail on the ground, and arranging a third support, a clamping device and a hydraulic push rod on the rail. The first support and the third support are pushed or pulled to make alternate circulation motion on the rail by reciprocating motion of a piston rod of the hydraulic push rod, so that the rotor moves forwards or backwards, andthe penetration and extraction motion of the rotor of a power generator set is achieved. The extraction and penetration method of the rotor is simple in process and high in safety; the rotor moves stably; and the extraction and penetration of the rotor can be completed without the traction of a travelling crane and a lifting device in an extraction and penetration process of the rotor.

Description

technical field [0001] The invention relates to the technical field of generator set installation and maintenance, in particular to a method for pulling through a rotor of a rail-guided hydraulic propulsion generator. Background technique [0002] Whether it is the maintenance of a new generator set or an old generator set, pumping through the rotor is one of the important procedures for generator maintenance. At present, the commonly used methods of pumping through the rotor in the industry include the dummy shaft method and the slider method. The false shaft method is usually extended by steel structural parts on both sides of the rotor, and then the two cranes are very synchronized and slowly put in and pumped through the rotor, which puts forward very high requirements for the driver and the traffic director. The slider method is a relatively mature method of pumping through the rotor, and it is also one of the main methods currently used in generators to pump out the r...

AI Technical Summary

Problems solved by technology

[0003] The dummy shaft method and the slider method are used to move the rotor by driving. There is no guiding mechanism in the forward direction of the rotor, and soft steel wire ropes or slings are used between the driving and the rotor. During the movement, the stator is easy to shake, which makes the central axis of the rotor Offset, causing the rotor to collide with the stator, and the safety is not enough

At the same time, the weight of the rotor is relatively large, and the speed needs to be strictly controlled during the process of pumping through the rotor. It is difficult to meet the requirements even if the commonly used crane is used at a low speed.

The false shaft method requires the two cranes to be very synchronized, which further increases the risk of pumping through the rotor.
