We produce fuel oil supply unit mainly used in diesel engine heavy fuel oil quality improvement and supply . It is easier for user management control and operation, which is more convenient for design and installation deb ing .In the aspect of the technique and process ，we adopts domestic and overseas advanced design idea, by means of advanced instruments and equipment to complete production .This equipment has reached the world advanced level with perfect fault detection and alarming system.The unit is with compact structure ,reliable work ,high automation and easy to maintain . The operating  principle is as follows :The fuel oil from daily light oil tank and daily heavy oil tank of fuel through unit 
         inlet  three-way valve, pass  the strainer from the supply pump to mix oil cylinder （collection chamber）and then by circulation booster pump to achieve boost pressure to enter into heater to heat,. Through viscosity test control system, control the steam regulating valve by installed on the heater steam inlet  to achieve control fuel oil viscosity within the set range. 
       Heating fuel oil is sent to carry out automatic backwash filter ，after finishing fine filtration  ，and is conveyed to fuel oil supply unit. Then the rest of fuel oil will return to mix oil cylinder by return port and mixed with fuel from supplement of supply pump and enter into the next circulation process .
In order to ensure to supply oil to marine diesel engine continuously ,there are two entire system as spare and can be mixed to use each other . 
Filter adopts the German BOLL automatic backwash filter. It is the most advanced domestic and foreign markets, most reliable performance fuel fine filter, the filter fineness reaching 10 μ. It solves disadvantage that after fine filter work a long time ， it need stop to clean & replace filter cartridge from the design aspects，which ensure the continuity of filter work &  consistency of filter fineness . The filter Cartridge service life is very long and It never replaces filter . 

The fuel oil viscosity control adopts imported EMERSON viscometer. This equipment is with structure compact, high technology level. It is the most competitive price viscometer in the current markets. The menu selection and operating system display is intuitive ,clear and easy to operate . Automatic or manual operation can be arbitrary selection. It can be adjusted according to actual condition and set temperature. Under setting control conditions, when there is a deviation, it can balance deviation in a fast and accurately  . It can be arbitrarily set alarm condition. The alarm status can be chosen unlock alarm, automatic lock alarm and manual lock alarm.

Electrical control box ,  based on the features of fuel oil supply unit and  combined with most of the crews operation habit, is designed by ourselves & with strictly supervision to produce . The electric control box can meet the requirements of various vessels with line concise, high automation and meet the requirements of unmanned engine room. This system control box use Schneider components, with two sets of independent system control circuit, two sets of control circuit of the electric power supply separately independent switchboard and emergency switchboard, two sets of power system, which can be mutually standby, and can be used in combination and the  isolated between lines for  safe maintenance. When the equipment broke down ,they can be automatic conversion with perfect fault detection and alarm system. All functions can be achieved by PLC procedural operation according to the customer’s requirements.
