● 用途Application 

本产品适用于燃用高粘度燃料油的船舶主、辅机和陆用电站的燃油系统。

单元为压力式燃油供油系统，具有热效率高、结构紧凑、外形美观，大大缩短造船周期。单元具有滤器自动反冲洗、自动粘度控制、泵自动切换、自动除气、PLC自动/手动控制、故障报警等功能，是船舶动力装置实现分布式集中监控的必备设备。

The fuel oil supply and booster module is used for fuel oil system including land power station and marine main engine, auxiliary engine burning high viscosity heavy fuel oil.

The Fuel Oil Supply and Booster Module is pressure-style fuel oil supply system. It has high thermal efficiency, compact structure, beautiful appearance, and cutting down the shipbuilding period. The unit is provided with automatic back-flushing of filter, automatic viscosity control, automatic pump alternative, automatic exhaust, PLC auto/hand control, automatic error alarm, and so on function. It is the essential equipment of vessels driving device making distributed central monitoring.

●原理概述Principle Description

全自动供油单元由燃油供给泵、循环泵、流量计、混油筒、粗油滤器、自清油滤器、燃油加热器、燃油粘度控制系统、PLC控制箱、仪表、阀件及附件等组成。

重油在日用油柜被加热至≥80℃进入单元燃油进口，经油滤器粗滤后，由供给泵供给混油筒，经与主机回油混合后，由循环泵增压至加热器加热降低粘度，自动清洗滤器精滤后，燃油加热的温度由粘度控制系统自动控制，符合主机燃用粘度的燃油输入主机。

The automatic fuel oil supply and booster module is composed of oil supply pumps, circulating pumps, flowmeter, mixing tank, primary fuel filter, self cleaning fuel filter, fuel oil heater, fuel oil viscosity control system, PLC electric controller, instruments, valves, attachments, and so on.

The heavy fuel oil is heated to more than 80 Celsius degree in the daily oil tank and that enters the inlet of fuel oil supply unit, by primary fuel filter. Then the fuel oil is supplied to mixing tank by supply pumps. By mixture with main engine return oil, circulating pump has increased the pressure to the heater to reduce the viscosity. The self cleaning filter finishes the filtering. Then the heavy fuel oil heating temperature is controlled by viscosity control system, and the fuel oil fitting for main engine enters the main engine.
