Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

The invention provides a replacing method of a hypovalve rotating wheel chamber. The hypovalve rotating wheel chamber rotates by 180 degrees around a center axis thereof through matching between a hand chain block and a corresponding lifting lug, so that the hypovalve rotating wheel chamber is lifted in or out of a machine pit. In the lifting process, according to the method, the positions of the lug are selectively adjusted or matched correspondingly according to the rotating angle and height change in lifting of the hypovalve rotating wheel chamber, so that the rotating wheel chamber regularly rotates according to a peripheral trajectory, and keeps a constant safety distance from other equipment such as a rotating wheel, and the consumed construction period in disassembly of the rotating wheel is shortened and the invested manpower, material resources and financial resources in disassembly of the rotating wheel are saved.

Description

【Technical field】 [0001] The invention relates to the technical field of hoisting of a runner chamber of a water turbine of a bulb tubular unit, in particular to a method for replacing a runner chamber of a lower lobe. 【Background technique】 [0002] The runner chamber of the bulb tubular unit generally includes a connected upper lobe runner chamber and a lower lobe runner chamber. The upper lobe runner chamber and the lower lobe runner chamber are equipped with runners. The standard installation process and sequence are: hoisting the lower lobe runner chamber → hoisting the runner → hoisting the upper lobe runner chamber. Usually, when the lower lobe runner chamber is replaced after the turbine unit is put into operation, the upper lobe runner chamber needs to be disassembled first, and then the lower lobe runner chamber can only be disassembled after the runner is disassembled. This method is convenient for hoisting operation and easy to control the quality, but the maint...
