Diesel switch

  • Changeover from preheated HFO to cold MDO/ MGO and vice versa represents a risk of fuel pump sticking or seizure due to the very small clearances in the fuel pump.
  • The Diesel Switch is able to do the changeover in a controlled way so that rapid temperature deviations are avoided. 
  • The changeover between HFO and distillate fuels can give problems for the fuel equipment, the process will need a high degree of automation to avoid incidents. MAN Diesel now offers the Diesel Switch, which ensures the necessary the flexibility and safety when changing between HFO and MDO/MGO.

The principle of the Diesel Switch- 

  • MAN Diesel recommends to reduce the load to 25-40% to control the changeover. 
  • The Diesel Switch ensures a controlled and safe changeover independent of the engine load. 
  • The Diesel Switch operates on a combination of the temperature at the engine and the time.
  •  If the fuel temperature at the engine inlet exceeds 2 degrees/minute the Diesel Switch will give an alarm and put the process on hold.
  •  The process will be logged in the Diesel Switch so that it can be used as documentation to port authorities after the changeover.

The Diesel Switch offers:

  • Touch screen control panel
  • Control handle for the changeover
  • Safety
  • Data logging
  • Changeover valve 
  • Magnetic coupling
  • Integrated sensor for actual position 
  • Integrated sensors for end positions
  • Integrated connection box
  • Manual override 
  • Controlling an MGO cooler or chiller
  • Data logging of temperatures and pressures 
  • Remote operation with second touch screen

    I'm truly intrigued with your composing aptitudes and furthermore with the design on your weblog. Is this a paid subject or did you adjust it yourself? Whichever way keep up the decent quality composition, it is uncommon to see a pleasant blog like this one nowadays. Magnetic coupling

Differences between MC/MC-C and ME/ME-C engines

The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators

Main engine interlocks

Interlocks are provided so that the engine can be started or reversed only when certain conditions have been fulfilled. When there is a remote control of engines, it is essential to have interlocks. This reduces the possibility of engine damage and any hazards to the operating personnel. Turning gear Interlock . This device prevents the engine from being started if the Turning gear is engaged. Running Direction Interlock . This prevents the fuel from being supplied if the running direction of the engine does not match the Telegraph. Starting Air Distributor in end position . This prevents starting from taking place if the shifting of the Distributor has not been completed. Main Lube. oil pressure, Piston cooling pressure, Jacket water pressure, and important parameters must be above the required minimum. Auxiliary Blower Interlock . The Auxiliary Blower is provided in case of Constant pressure turbo charging. Air Spring pressure Interlock . In case of the present generation

Why is a man hole door elliptical in shape?

Any opening in a pressure vessel is kept to a minimum and for a man entry an elliptical hole  is lesser in size than the corresponding circular hole. More over it is prime concern to have a  smoothed generous radius at the corners to eliminate stress concentration. Hence other  geometrical shapes like rectangle and square are ruled out.  To compensate for the loss of material in the shell due to opening, a doubler ring has to be  provided around the opening. The thickness of the ring depends on the axis length along the  dirrection in which the stresses are maximum and the thickness of the shell. It is important to  align the minor axis along the length of the vessel, as the stress in this direction is  maximum. Longitudinal stress: Pd/2t where P= pressure inside the vessel, d= diameter of the arc, t=  thickness of the shell plating  Circumferential stress: Pd/4t  More over a considerable material and weight saving is achieved as minor is along the  direction of maximum stress.
