Problems solved by technology
The cost of deep well pumps is generally relatively high, and the installation is time-consuming and laborious. Once the installation requirements are not met, the replacement of parts or even the pump body will cause major economic losses to the shipyard, and may even cause delays in delivery, which greatly affects the production of the shipyard. and construction

The invention provides a deep-well pump and liquid tank installation precision control method. The deep-well pump includes a pump body and a motor to be connected with the top of the pump body. The method comprises the following steps: step 1, unloading the pump body from a transport cart; step 2, coarsely centering a guide ring and an air chamber flange; and step 3, finely centering the guide ring and the air chamber flange, installing the pump body on the liquid tank, and installing the motor on the pump body. Through the method, the precision of the whole process of pump body transporting and hoisting and pump body and liquid tank installing can be controlled, the precision indexes of the deep-well pump are controlled within a controllable range, and the precision of deep-well pump and liquid tank installation can be improved.
Description
technical field [0001] The invention relates to a liquefied gas marine deep well pump, in particular to a method for controlling the installation accuracy of a liquefied gas marine deep well pump and a liquid tank. Background technique [0002] The liquefied gas carrier 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 Due to the low temperature of the gas, the common liquid injection and extraction technology is no longer applicable. This work must be done with the help of a special device. At present, deep well pumps are mainly used to solve the technical problems of exchanging cryogenic liquids in liquid tanks and hulls. As modern society pays more and more attention to safety issues, the safety of liquefied gas carriers has become a subject that must be solved. During the loading and unloading process of liquefied gas ships, various leaks are most likely to occur, which will affect the safety of liquefied gas ships. [0003] It is a relatively lo...
