Renjith Rajendran May 29, Very comprehensive and useful information in simple language This ensures that any leakage in the line will be immediately detected without the loss of much of hydrualic oil.
These tests are normally carried out and analysed by a Framo service engineer either at a predocking inspection or special attendance for this activity. On each ship, there could be few locations for emergency stop for Hydraulic system. The oil can then be refilled either from the standby tank or spare manula whichever available.
Do not use any cleaning fluid containing chlorinated hydrocarbons. Correction sir i mean its the proportional valve that was replaced. The following preventive maintenance is recommended for optimum life of the system. Bernard Argenio May 11, MR Fraom 16, One of the feed pumps must always be running when the power packs are not in operation. Correct operation is also an important parameter to keep the maintenance cost at an acceptable level. Failure in one system is not likely to interfere with other systems.
If the suction valve for the high pressure pump is fram, the power pack will trip. The built in pressure transmitters give a mA bar feedback signal to the instruments on the control panel. Ensure proper air venting. Learn the difficult concepts of sailing described in a easy and story-telling way.
One of the feed pumps must always be running when the system is not in operation and if it stops, the protection pressure low alarm is initiated. STC of the pump controls the speed of the pump by allowing pujp the required amount of hydraulic oil to pass through to the hydraulic motor. Framo pumps are fraom pumps. In these cases we need to fill the cofferdam with some liquid DOP in case of loading TDI so that cofferdam is not blocked with the cargo.
The feeders and DC power supplies are monitored by relays provided with status lamps.
Thank you very much for this useful and easy to read post. Framo Cargo Pumping Tagged: If a shut down function is initiated, the PLC will give shut down command to the power packs in sequence. Awesome explanation Sir crystal clear Thankful for all topics you have explained Thank you very pup sir.
Framo Hydraulic Cargo Pumping System on Ships
Inspection intervals for the zinc anodes assembled on ballast pumps and other pumps depends mainly on time of exposure, water level in tank, water corrosivity and temperature. Debris switches to be checked if alarm is indicated.
Air if any is auto released to the Hydraulic tank while recirculation. Thanks to you for your useful bloging post.
Maintenance on Framo Cargo Pumping System
Thx sir, the concept of framo system explained very well. Pankaj mehta Apr 17, When i tried to increase the system pressure to bars the indication of the system pressure started to fluctuate. There is hydraulic seal that prevents hydraulic oil leakage to the cargo side.
I learned a lot and answered my questions Mwnual any of the seal is leaking, it need to be replaced with new seal after the discharging and tank cleaning of the tank. Same goes for when the surrounding temperature is higher. The hydraulic oil is made to pass through a oil cooler to cool the oil before delivery on deck.
Short, crisp and full of value. As you might have guessed, there is something in the Framo pump to prevent that.
All samples to be taken at Framo oil sampling point. This test requires calibrated manometers and accurate measurements. This is exactly what Speed torque controller does. The consumer pressure in remote control is running at bars.
