Semiautomatic Fuel Oil Supply Plant

Semiautomatic Fuel Oil Supply Plant

1. Semiautomatic Fuel Oil Supply Plant Preface
Semiautomatic fuel oil supply plant is services for the fuel supply of diesel engine, can supply pressure stably for diesel fuel into the machine, meet the temperature and viscosity requested by diesel engine, to achieve the desired fuel burning effect, give full play to the maximum working efficiency, reduce exhaust of diesel engine and carbon, prolong the service life of diesel engine and parts.
This device is an individual and whole unit module, through the combination of various components requested by the system, let the users greatly improve their work efficiency during the design, construction, installation and debugging. Facilitate the operation of the turbine staff management and maintenance at the same time.
2. Semiautomatic Fuel Oil Supply Plant Basic Structure
Semiautomatic fuel oil supply plant with fuel oil supply system, heating system, fuel purification system, viscosity/temperature control system and electrical components. Oil supply system part configuration for oil pump, booster pump, usually for one case with two sets of each, according to different oil products, diesel engine burning optional emergency diesel pump, low sulfur oil pump and so on.
Heating system according to the different heat source system by each user and the size of a diesel engine power, selection and configuration, it is mainly used for heavy oil heating. At the same time, through the fuel fine filter or with automatic backwash filter in parallel purification, fuel oil viscosity controller by controlling the electric control valve regulating heat flow so as to achieve the aim of controlling heavy oil viscosity, system configuration has the 3-way switch valve, strainer, pressure regulating valve, flow meter, mix oil drum, temperature control valve, relief valve and other different types of valves and instruments and electric control system composition.
3. Semiautomatic Fuel Oil Supply Plant Principle Description
The semiautomatic fuel oil supply unit is composed of oil supply pumps, circulating pumps, flow-meter, mixing tank, primary fuel filter, semiautomatic cleaning 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 80C 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.
4. Electrical control system fault and processing of Semiautomatic Fuel Oil Supply Plant
(1) Automatic running self checking of standby starting:
According to the step of normal working start the 1# oil supply pump and 1# booster pump after the fuel supply system is stable, then the 2# oil supply pump and 2# booster pump controller switch is in standby position, close # 1 running pumps when pressure drops to the set point 2 # standby pump will start automatically. At the same time control box alarm indicator panel "standby oil supply pump start" or "standby booster pump start" red light is shining, the standby pump automatically start and have alarm signal output. Conversely, said standby starting system fault.
(2) Starter box fault and repair:
In normal operation working, the running of one group of green light is bright, and the another set of lights in the standby state will be off.
When the green lights running off, a loss of electric alarm:
Check the three-phase power supply is normal.
Check oil pump motor is normal, and then open the start box to check whether the motor protection device automatically jump off, to be removed after the failure, reswitch on the protective device.
When there is a green running lights and no loss of electric alarm:
Check the three-phase power supply is normal.
Check whether the control switch is in the normal working condition.
Check whether the AC contactor and motor protector of oil pump is normal
When the set of standby pump does not start automatically:
Check whether the position of the standby switch is normal.
Check whether there is any damage to the miniature circuit breaker and the intermediate relay in the start box.
Check whether the external pressure controller is damaged or the oil to the pressure control for dirty is blocking.
