Description

[0001] Shaft seal replacement jig [0002]

The present invention relates to a jig device for shaft seal replacement. And more particularly, to a jig for replacing a shaft seal, which allows a shaft seal replacement operation to proceed more safely and quickly.

Generally, a shaft seal system is used as a device for sealing the shaft of a pumping power plant.

1, the shaft sealing device 1 includes a fixed support 10 positioned on the upper side and formed in a ring shape, a movable ring 10 mounted on the lower side of the fixed support 10, And a shaft seal 30 made of carbon and positioned at a lower portion of the moving ring 20. [

Here, the fixed support portion 10 is provided with a bolt fastening portion 12 in which a second fastening hole 12a is formed to fasten a bolt (not shown).

The shaft seal 30 must be replaced after a period of use.

Conventionally, the entirety of the fixed support 10 and the movable ring 20 is lifted by about 30 cm to replace the shaft seal 30, and the disassembling operation of the shaft seal 30 proceeds.

However, since the entirety of the fixed support portion 10 and the movable ring 20 reaches about 1,100 kg, it is not easy to lift the worker in a narrow space where the waist can not be opened.

In addition, when the conventional method of lifting the fixing support 10 at three points using a screw jig bolt (not shown), the fixing support 10 is immersed in water and the screw jig bolt fastening part is corroded much Therefore, there are many cases where the bolt is damaged due to the corrosion and weight of the bolted portion when lifted, and there is a risk that there is a considerable risk due to corrosion.
