A propeller hydraulic assembly control system and control method

Abstract

The invention discloses a propeller hydraulic assembling control system and control method. The propeller hydraulic assembling control system is characterized in that an engineering machine, a multifunctional PCB board, an analog input and output terminal board, a digital input terminal board, a first proportional pressure valve, a second proportional pressure valve, a first pressure sensor, a second pressure sensor, a displacement sensor, a relay output terminal board, and a relay, a first hydraulic oil passage is arranged on an impeller hub to supply radial pressure to the impeller hub, and a second hydraulic oil passage is arranged in the axial direction of the propeller shaft, the first hydraulic oil passage is provided with a first hydraulic oil pump, the first proportional pressure valve, and the first pressure sensor, and the second hydraulic oil passage is provided with a second hydraulic oil pump, the second proportional pressure valve, and the second pressure sensor. By means of the control system, during the propeller installation, the automation process of the propeller hydraulic assembling can be realized, so that the time and manpower are saved, the assembling efficiency is improved, and the labor intensity is alleviated.

Description

Technical field [0001] The invention relates to a propeller hydraulic assembly control system and control method. Background technique [0002] At present, most large ships in the world use hydraulic keyless connection to fix the relative position of the propeller core and the propeller shaft. The hydraulic keyless connection is to make the propeller shaft and the propeller core form an interference fit within the elastic range of the material through the action of high pressure oil. With the aid of the interference fit, a huge contact friction force is generated, so that the propeller and the shaft are reliably connected together to achieve transmission. The function of the torque issued by the host. The hydraulic keyless connection of the propeller not only has good assembly quality, strong reliability, but also convenient disassembly and assembly work, which provides a strong guarantee for the navigation performance of the ship and the safety of the cargo and personnel on the...

Problems solved by technology

[0003] Although the propellers of newly-built large ships at home and abroad mostly adopt hydraulic keyless installation, most shipyards still manually control the installation oil pressure during installation, and the degree of automation of the supporting equipment for propeller keyless installation is not high, which not only makes the installation quality of propellers unsatisfactory. Guaranteed, but also increases the cost of shipyard input
