Fuel Oil Supply and Booster Module

Fuel Oil Supply and Booster Module

1. Fuel Oil Supply and Booster Module Preface
The fuel oil supply and booster module 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. Fuel Oil Supply and Booster Module Basic Structure
This fuel oil supply and booster module 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. Fuel Oil Supply and Booster Module Working principle
Diesel or heavy oil respectively from the service tank is entered into the oil supply unit, the 3-way switch valve, through the coarse filter before to supply pump, two as spare for oil pump. For oil pump exported equipped with a pressure regulating valve can be adjusted for the pump working pressure and outlet is equipped with pressure controller, pressure gauge to check the oil pump working condition. Fuel after fine filter to filter the flowmeter to mix oil drum, unit filter is installed in parallel of manual and automatic filter, import and export have their respective valve, normal use automatic filter, by-pass filter used for backup.
Mixing barrel with liquid level controller is used to detect mix oil drum level, low level alarm signal to the control box. System of diesel engine oil, hot oil into the mixing barrel, mixes with cold oil for oil pump input, produce oil and gas, by mixing barrel at the top of the automatic exhaust to crude oil service tank, and is equipped with emergency hand exhaust to the bottom of the oil supply unit. After the fuel mixture degassing in the mixing barrel into the booster pump, two as spare booster pump; Outlet is equipped with pressure controller, pressure gauge to check the oil pump working condition.
After booster pump to the fuel oil heater heating (steam or heat conduction oil heat exchange), heating fuel after a viscometer to measure viscosity, viscosity and viscosity controller feedback signal detection. By electric valve control of heat flow of feed, best viscosity control fuel into the diesel engine fuel injection pump, extra fuel system at the time of the return pipe and oil return back pressure regulating valve back to unit mix oil drum, mixed with oil in the cold mixing barrel and fuel supply pump cycles. System equipped with pressure gauge and relief valve at the exit, display fuel outlet pressure and adjust the fuel pressure into the machine. But above all fuel oil supply unit set oil supply, purification, cyclic heating and complex viscosity/temperature control function.

4. Troubleshooting of Fuel Oil Supply and Booster Module

Number

Alarm phenomenon

Possible reasons

Elimination method

1

Standby power to start the alarm

Main power loss

Check the main power power switch

2

Oil supply pump electric lose alarm

Motor protector failure

Reset or replace protector

3

Booster pump electric lose alarm

Motor protector failure

Reset or replace protector

4

Standby oil supply pump start alarm

(1)Motor protector failure

(2)Oil supply pressure controller failure

(1)Reset or replace protector/contactor

(2)Change pressure controller

5

Standby booster pump start alarm

(1)Main booster pump lost electricity

(2)Booster pump pressure controller failure

(1)Reset or replace protector/contactor

(2)Change of pressure controller

6

Ultra high temperature alarm

(1)Actual temperature is higher than the set temperature above 10 in temperature panel

(2)Pressure type temperature controller failure

(3)Temperature instrument failure

(1)Check the pressure type temperature control or replacement

(2)Check the temperature gauge or replacement

7

Filter blocking alarm

(1)Differential pressure between before and after the filter too high caused by filter blocking, filter impurities can't automatic discharge

(2)Filter differential pressure controller failure

(1)Manual removal filter cleaning

(2)Change the filter pressure controller

8

low level warning

(1)Exhaust berry oil level below the float

(2)Liquid level floating ball stuck or damage

(1)Check whether liquid level float impurities stuck or replacement

(2)Exhaust berry oil level higher

5. Certificates of Fuel Oil Supply and Booster Module: ABS, BV, DNV.GL, KR, RINA, NK, LR and CCS approvable.
