Framo. Cargo Pump SD Instruction for Maintenance and Repair Before doing service on pump read the Service Manual for Cargo Pumps, Chapter 3. Well, he had worked on ships (tankers) with Framo pumps. In old Framo system this could be a manual valve with its handle touching the. Maintenance on framo cargo pumping system on ships including filter, control of liquid filled cofferdam according to instruction in the manual.

Particle counting and water analyses every 3 months, and full oil analyses once a year.
Your email address will not be published. We do this by a lever provided in the cargo control room.

Now when the system is always under positive pressure, the chances of moisture mwnual are minimum. It is pmp important that operation instructions are followed carefully. When the oil temperature is well within operating range, other power packs can be started. The consumer pressure in remote control is running at bars. If the suction valve is even slightly closed, its looses the touch of sensor and trip is activated.
STC also prevent the pump to overspeed by controlling the amount of oil to the hydraulic motor of the pump. Framo submersible pumps are centrifugal pumps. I am working on vessel with the framo system and I need some help. In case of failure to main feeder, automatic change-over to back-up will take place.
Inspect anodes regularly until rate of consumption is established. It is therefore recommended to change wear rings if the pump is overhauled for other reasons. In Framo system, you will not be able to see the hydraulic motor as it is placed in the outer casing.
We carried out cleaning of filters and replacement of directional valve. Correction sir i mean its the proportional valve that was replaced. In this case the a proximity sensor is fitted on top of the valve, farmo senses if the valve is fully open or not.
It is recommended to inspect the anodes annually until rate of consumption ;ump established. Off course if air is still suspected in the system, there is air purging arrangements in the Framo.

Purging reports to be filled in during every round-trip. The command signals from potentiometers at the front of the control panel are fed directly into the proportional valves for speed control. I am not going in details of how a centrifugal manuzl works. In steam turbine centrifugal pumps, this energy is provided by steam. Vent the system regularly until the air is out of the system. This ensures that the suction valve of the pump to take suction from hydraulic tank is not inadvertantly closed.
Replace any damaged parts. This is because higher temperature can damage the seals and other components and also it accelerates the degradation of oil. This makes the knowledge of Submersible pumps and Framo system so much important.

Framo is leader among the submersible pumps fitted on board tankers. STC then releases the amount of manuzl to the hydraulic motor which will be corresponding to the amount to lever lifted. Further analyses can be carried out by testing the cargo pump against closed discharge valve. This ensures that any leakage in the line will be immediately detected without the loss of much of hydrualic oil.
In this case the third feed pump will start automatically. A running signal is provided for indication on the control panel.
