In order to ensure efficient and safe operation of this type of hydraulic cargo pumping system, a sound knowledge regarding its functioning is imperative. This course familiarizes the participant with all aspects of the system and enables them to operate it safely and efficiently. The participants are exposed to the layout of the hydraulic circuit; explanation of the working of the power packs; oil cleanliness aspects and its importance; troubleshooting aspects - dealt with logically, systematically and in detail; the various safety features of the circuit - various alarms / trips and the emergency overrides. The working of centrifugal pumps, both in parallel and in series, are also covered along with the capacity curves for the pumps and their interpretation and use for optimal cargo discharge. Stripping operation, cargo pump evaluation curves, analysis of purging results and use of the emergency portable pumping equipment also form part of this course.
The construction of the cargo pump is also covered in detail and various basic maintenance procedures (renewal of wear rings or cargo seals) explained. Two videos, one detailing cargo pump maintenance and the other dealing with operational aspects (loading / discharging / stripping / tank cleaning etc). are also shown. Finally, the participants are provided hands-on practice on the dismantling of the FRAMO cargo pump, replacing wear rings, cargo seals, mechanical oil seal and also the hydraulic motor bearings. They are also exposed to hands-on dismantling and troubleshooting the Flow Control Valve FCV-800 which functions as a ‘governor’ for the cargo pump. In summary, this course provides a forum for theory lecture delivery, exercises, hands-on dismantling / reassembly training and group discussions leading to improvement in competency and confidence in handling the FRAMO hydraulic and cargo equipment.
