Abstract

PURPOSE:To perform inspection work in a short time with small torque by perform detaching work as tension is loaded on a main flange stud. CONSTITUTION:After guide screws 102 are set on brackets 101 and nut parts 104 of a base stand 103 are incorporated, the base stand 103 is lifted up to the lower end of a pump casing 20. A nut detachable fitting body 107 is trans ferred upward, a nut detachable unit 112 is made to approach the edge of a main flange stud 24 and an attaching nut 25 is attached and detached. At this time a screw part is threadedly engaged with the tensile screw part of a main flange stud 24 and prescribed pressure is loaded in an oil pressure cylinder. Therefore, since tensile load is given on the main flange stud 24, attachment and detachment work of the attaching nuts by which a main flange is fixed at the time of maintenance and inspection of an internal pump can easily be performed in a short time.
