Device and method for drying marine underwater motor

Abstract

A device for drying a marine underwater motor is installed on a deck of a marine working mother ship provided with a gas storage tank. The underwater motor is provided with a compensator port and a motor cavity oil injection exhaust port. The device for drying the marine underwater motor comprises a main gas pipe, an auxiliary gas tank, an auxiliary gas pipe, a gas heater and a hot gas pipe. One end of the main gas pipe is connected with the output end of the gas storage tank, and the other end of the main gas pipe is connected with the input end of the gas storage tank. The auxiliary gas tank is a sealed metal structural component, and a gas flow control valve is arranged at the output end of the auxiliary gas tank. One end of the auxiliary gas pipe is connected with the output end of the auxiliary gas tank, and the other end of the auxiliary gas pipe is connected with the input end of the gas heater. The gas heater comprises a tube body and electric heating tubes which are arranged inside the tube body. One end of the hot gas pipe is connected with the output end of the gas heater, and the other end of the hot gas pipe is connected with the motor cavity oil injection exhaust port of the underwater motor. The device and method for drying the marine underwater motor have the advantages of being low in maintenance cost, short in working cycle and capable of being used for drying the underwater motor on a marine operation site.

Description

technical field [0001] The invention relates to a maintenance device for underwater equipment, in particular to a drying equipment and method for an underwater motor at sea, and belongs to the technical field of marine engineering. Background technique [0002] Our country has a vast territorial sea, and the development of marine resources has increasingly become the leading industry of our economy. The marine strategy has become the core national interest of our country. Ocean development cannot lack advanced underwater operation equipment, and no matter how reliable the equipment is, it will inevitably need to be repaired. [0003] When the underwater trenching machine used for subsea operations dives into deep water, the underwater motor of the jet flushing pump will be damaged by the storage capsule of its pressure compensator, which will cause water to enter the underwater motor, and its insulation will drop to 6 megohms Or even below, so that it cannot work normally. ...

AI Technical Summary

Problems solved by technology

Although this traditional repair method is effective, it needs to transport the jetting pump back to the factory, so the transportation is inconvenient and expensive, and the construction period of offshore operations is delayed

[0004] After searching the prior art documents, it has not been found that the same or similar literature reports as the subject of the present invention have been found so far.
