Due to the change of shipping market conditions, conditions of a shipowner applying a high-power low-speed diesel engine are different, the current transportation volume is small, the high-power low-speed diesel engine is frequently operated in a low-load state and is long in time, the period for replacing vulnerable parts such as a sealing ring and a shaft seal is shortened, and the damage rate is greatly increased due to the fact that a motor of an auxiliary blower is operated under low load for a long time. Because the motor and the fan are heavy, the replacement frequency is high, the phenomena of lifting danger and poor installation effect often occur, and more faults are caused, so that the problem that the effect of lifting and installing the auxiliary air blower needs to be solved at present is solved.
According to the maintenance of the auxiliary blower, wearing parts such as a seal ring and a shaft seal need to be replaced according to a replacement period. When the auxiliary blower needs to be hoisted during replacement, taking 6S60ME-C as an example, the weight is 520Kg, and the traditional mode of a motor hoisting ring or a hoisting belt is used, so that not only is the construction of workers difficult, but also certain safety accident risks exist, and after the blower is installed, the horizontal installation effect is difficult to ensure, the load of a bearing of the auxiliary blower motor is increased, and the secondary damage of the auxiliary blower motor is easy to occur under the condition of low-load operation. This not only results in economic loss of purchased parts from shipowners, but is susceptible to credit risk for ship delay, which can affect the image of my host products.
The original auxiliary air blower is fixed only by a flange, when the air blower runs, the stress of the mounting flange is large under the action of rotating force, and the mounting flange is hoisted by using a hanging strip or a hoisting ring, so that the stability is poor, the swing is easy, and the replacement of parts or the mounting and centering are very difficult.
Therefore, companies are urgently required to innovate and invent a novel hoisting method of a main engine auxiliary blower and a novel auxiliary tool, so that the current situation that safety accidents may occur when the auxiliary blower and parts are disassembled from a ship is changed, the assembly quality of the parts is improved, the probability of secondary damage of a blower motor is reduced, the construction efficiency is improved, and the disassembly time is shortened.
