Water Injection Pump Control

Water injection pump and booster pump control scheme posted in industrial professionals.

Water injection pump control.

Water injection package piping and components. The injection mixes methanol and water to reduce intake temperatures sometimes by up to 100f. Hi all i m currently working on a water injection package for offshore oil gas production facility. Water will corrode an efi pump shut in a very short period of time.

The high pressure high flow water injection pumps are placed near to the de oxygenation tower and boosting pumps. The pump and all the sensors and actuators are controlled by an expanded engine management system. The injection quantity can be varied depending on load engine speed and temperature which helps to keep water consumption to a minimum. The control box that i use is from snow performance.

The water injection rate is 60 000 bpd during early field life this water will be treated sw but as the. The result of the injection is not quick it needs time. It was originally attached to the maf sensor which has a variable voltage of 0 5v. 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.

A simplex high pressure pump skid used for liquid fuels or a simplex low pressure pump skid is used for gas fuels. Demineralized water is injected into the combustion chamber to regulate the flame temperature. Control over the water injection is important. The pump supplies water to the injectors at a pressure of approximately 10 bar.

Water injection has a cooling effect on the engine head valves and cylinder. 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. They fill the bottom of the reservoir with the filtered water to push the oil towards the wells like a piston. Exhaust temperatures egt are largely unaffected at recommended water fuel ratios.

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. Includes the following hardware.
