Abstract

The invention discloses a magnetic drive pump for liquefied natural gas delivery, which comprises a center shaft, an internal magnetic rotor, a connection seat and an external magnetic rotor. The internal magnetic rotor and the connection seat surround the center shaft, the external magnetic rotor surrounds the internal magnetic rotor, the internal magnetic rotor is fixedly connected with the center shaft, the connection seat is connected with the center shaft through a first bearing, a spacer sleeve is arranged between the internal magnetic rotor and the external magnetic rotor and is fixedly connected with the connection seat, and a seal gasket is arranged at the joint between the spacer sleeve and the connection seat. Besides, the spacer sleeve and the connection seat are connected fixedly and incapable of moving relative to each other, the seal gasket is arranged at the joint between the spacer sleeve and the connection seat, and then static seal between a pump and a medium can be realized and the pump is safe and reliable in structure, so that the possibility of medium leakage is reduced, unsafe factors generated in delivery process of liquefied natural gas are reduced greatly and safety and reliability of the pump in running are improved. In addition, structures below a mounting platform of the magnetic drive pump can be submerged under liquid level completely, and accordingly heat insulation measures to pipelines when the magnetic drive pump is mounted on the ground and auxiliary cost for the pipeline is lowered.

Description

technical field [0001] The invention relates to the technical field of liquefied natural gas transportation, in particular to a magnetic drive pump for liquefied natural gas. Background technique [0002] Natural gas is becoming more and more popular as a clean energy source. Many countries have listed LNG (liquefied natural gas) as the preferred fuel, and the proportion of natural gas in energy supply has increased rapidly. Liquefied natural gas is growing at a high rate of about 12% per year, making it one of the fastest growing energy industries in the world. In recent years, global LNG production and trade have become increasingly active. LNG has become a scarce and clean resource and is becoming a new hot spot in the world's oil and gas industry. At present, with the wide application of liquefied natural gas transportation projects, a large number of pumps are required for its transportation. At present, all the pumps used are mechanical seal pumps, and their technolog...
