摘要

For LNG terminals with underground storage tanks, it is economically required to reduce equipment such as pumps to simplify the system. If the primary in-tank pump could be developed with a capacity of approximately 100ton/h and total head of approximately 1000m, it wou be possible to elimiante the secondary pumps. In this case, the high head and large capacity of the primary pump will cause an excess axial thrust load on the rotor, so the following research was performed to resolve this problem.
