4050L Automatic Fuel Oil Supply Unit

4050L Automatic Fuel Oil Supply Unit

Introduction

When the fuel supply device serves the fuel supply of the diesel engine, it can keep the supply pressure stable, so that when the diesel enters the machine, it can meet the temperature and viscosity of the diesel engine, achieve the ideal fuel combustion effect, give full play to the maximum work efficiency, and reduce the exhaust gas and Carbon emissions extend the service life of diesel engines and their parts.

Basic structure

Fuel supply equipment, including fuel supply system, heating system, fuel purification system, viscosity/temperature control system and electrical components. Fuel pump and booster pump fuel supply system component configuration; usually two sets in one case, according to different oil products, emergency diesel pump, low-sulfur fuel pump, etc. can be selected for diesel engine combustion. The heating system is mainly used for heating heavy oil according to the size, selection and configuration of the different heat source systems and diesel engine power of each user.

At the same time, through the fuel fine filter or in parallel with the automatic backwash filter, the fuel viscosity controller adjusts the heat flow by controlling the electric regulating valve to achieve the purpose of controlling the viscosity of the heavy oil. The system is equipped with a three-way switch valve, filter screen, pressure regulating valve, , Flow meter, mixing oil drum, temperature control valve, pressure relief valve and other different types of valves and instruments and electronic control system.

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 flow meter 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 visco meter 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.
