Hydraulic system of crude oil outward transportation device

Abstract

The invention discloses a hydraulic system of a crude oil outward transportation device and belongs to the field of hydraulic control. The hydraulic system of the crude oil outward transportation device comprises a hose winch hydraulic system, a discharging pipe extending and retracting hydraulic system and a discharging pipe lifting hydraulic system. The hose winch hydraulic system comprises winch motors and a winch control module. The discharging pipe extending and retracting hydraulic system comprises a discharging pipe motor and a discharging pipe extending and retracting control module. The discharging pipe lifting system comprises a first discharging pipe oil cylinder, a second discharging pipe oil cylinder and a discharging pipe lifting control module. The hydraulic system further comprises a controller. The controller is electrically connected with a first three-position four-way electromagnetic reversing valve and a second three-position four-way electromagnetic reversing valve. The controller is arranged to achieve that when the controller controls the first three-position four-way electromagnetic reversing valve through a first electrical signal to enable the winch motor to work, the controller controls the second three-position four-way electromagnetic reversing valve through a second electrical signal to enable the discharging motor to work. The hydraulic system of the crude oil crude oil outward transportation solves the problem that synchronous working of the crude oil outward transportation device is difficult.

Description

technical field [0001] The invention belongs to the field of hydraulic control, in particular to a hydraulic system of a crude oil export device. Background technique [0002] The crude oil export device is an important part of the offshore floating production storage and offloading device (Floating Production Storage and Offloading, FPSO), which is used to transport the crude oil stored in the FPSO to the shuttle tanker. [0003] The crude oil export device generally includes a hose winch and a pipe discharge device. The hose winch is used to retract the oil delivery hose wound on it, and the pipe discharge device is used to enable the oil delivery hose to be recovered on the hose winch in sequence. . Usually, the hose winch is equipped with a hose winch hydraulic system for driving the drum of the hose winch to rotate, and the pipe arrangement is equipped with a pipe extension hydraulic system for driving the extension and retraction of the pipe arrangement. The calandri...
