Installation method of deep well pump and liquefied gas ship

Abstract

The invention provides a mounting method of a deep-well pump and a liquefied gas carrier. The mounting method of the deep-well pump mainly comprises the steps of mounting a bearing device, mounting a shaft seal device and mounting a coupler. The deep-well pump manufactured through the mounting method is high in mounting precision. The liquefied gas carrier comprises a liquid tank, and the liquid tank is connected with the deep-well pump manufactured through the mounting method of the deep-well pump. The upper end of a middle pipe of the deep-well pump is connected with a gas chamber flange arranged at the top of the liquid tank. A guide ring supporting component is arranged at the top of a liquid collecting well at the bottom of the liquid tank and provided with a guide ring. The lower end of a pump cylinder of the deep-well pump penetrates the guide ring and then stretches into the liquid collecting well. By means of the liquefied gas carrier, liquefied gas leakage or other risks possibly happening in the liquefied gas loading and unloading process of the liquefied gas carrier can be avoided.

Description

technical field [0001] The invention relates to a deep well pump, in particular to a deep well pump installation method and a liquefied gas ship. Background technique [0002] The liquefied gas ship is used to load and transport liquefied gas in a low temperature state. Due to the low temperature of the gas, the common liquid injection and extraction technology is no longer applicable. At present, liquefied gas ships mainly use deep well pumps to solve the exchange between the low-temperature liquid in the liquid tank and the hull. With the improvement of people's safety awareness, people pay more and more attention to the safety of liquefied gas ships. During the loading and unloading process of the liquefied gas carrier, various leaks are most likely to occur, which affects the safety of the liquefied gas carrier. The low installation accuracy of existing deep well pumps is the main reason for the leakage of liquefied gas ships during loading and unloading. Therefore, ho...
