Water Injection Pump Control

Hi all i m currently working on a water injection package for offshore oil gas production facility.

Water injection pump control. This normally occurs when the engine is heavily loaded and running at full power however may occur outside of these times in specialized engines or applications. Water injection package piping and components. The system comprises of sea water sw lift pumps and sw treatment filtration deaeration. Water injection has a cooling effect on the engine head valves and cylinder.

The injection quantity can be varied depending on load engine speed and temperature which helps to keep water consumption to a minimum. Exhaust temperatures egt are largely unaffected at recommended water fuel ratios. Demineralized water is injected into the combustion chamber to regulate the flame temperature. It was originally attached to the maf sensor which has a variable voltage of 0 5v.

The pump and all the sensors and actuators are controlled by an expanded engine management system. Includes the following hardware. Water injection pump and booster pump control scheme posted in industrial professionals. The pump supplies water to the injectors at a pressure of approximately 10 bar.

A simplex high pressure pump skid used for liquid fuels or a simplex low pressure pump skid is used for gas fuels. Control over the water injection is important. They fill the bottom of the reservoir with the filtered water to push the oil towards the wells like a piston. It must be injected only when conditions within the engine would otherwise be sufficient to cause detonation or other undesirable effects.

Now the technology of water methanol injection is useful as an effective way to increase power and control detonation for vehicles that offer turbocharged or supercharged systems. The water injection rate is 60 000 bpd during early field life this water will be treated sw but as the. The high pressure high flow water injection pumps are placed near to the de oxygenation tower and boosting pumps. Water will corrode an efi pump shut in a very short period of time.

The control box uses the regulators voltage as a reference to control a 0 12v output to the pump to vary the water pressure for injection. The result of the injection is not quick it needs time.
