転可能状態となる。When the pump 5t is installed in the cylindrical perl 2, the cylindrical perl 2 is filled with an inert gas such as elementary gas, and the pump 5t is lowered from the top in a T-shape. When the pump 5 reaches the lowest position, its own weight pushes down the bracket 6t against the force of the spring 9 to open it, as shown in FIG. After the inert gas is removed, the pump 5 is ready for operation.
