Method for manufacturing tank unit
A method for manufacturing a tank unit includes performing a pressure resistance inspection on each of a plurality of high pressure tanks before connecting the high pressure tanks, and connecting a gas flow path to the high pressure tanks that have passed the pressure resistance inspection.
1. A method for manufacturing a tank unit, comprising:
performing a pressure resistance inspection on each of a plurality of high pressure tanks before connecting the high pressure tanks; and
connecting a gas flow path to the high pressure tanks that have passed the pressure resistance inspection, wherein
each of the high pressure tanks has an opening in a top and a bottom of each of the high pressure tanks,
the opening in the bottom is sealed with a plug and a liquid is injected through the opening in the top into each of the high pressure tanks to perform the pressure resistance inspection,
after the plug is removed and inside of each of the high pressure tanks is dried, an end cap is attached to the opening in the bottom, and
the end cap of each of the high pressure tanks is fitted in a bottom connector to connect the high pressure tanks.
2. The method according to claim 1 , wherein
the tops of the high pressure tanks are connected by a top connector when connecting the gas flow path to the high pressure tanks, and
all the high pressure tanks are contained in a smallest rectangular parallelepiped containing the bottom connector and the top connector.
