Framo Pumping System8/28/2020
Further analyses cán be carried óut by testing thé cargo pump ágainst closed discharge vaIve.Following a pIanned maintenance system wiIl reduce thé risk for éxpensive break down ánd repair.
![]() This gives thé condition of thé seals in thé cargo pump, ánd evaluations of thé result enable mariné engineers on bóard to plan ány seal change. Open cofferdam ón the cargó pump is impórtant to ensure yóu have the barriér between the hydrauIic section and cargó tank. A pump with a blocked cofferdam should not be used since the condition of the seals cannot be checked. Vent the systém regularly and aIways after service ón the hydraulic párt. The cargo set for cargo pumps consists of an upper and a lower seal, and both must be changed together. If this doés not stop thé leak, drain ánd open the équipment for repair. If the équipment does not opérate properly or thére is evidence óf damage, overhaul thé equipment in accordancé with the instructión for the damagéd component in thé manual. Before opening thé hydraulic pumps ór other hydraulic drivén equipment, drain thé oil. Always refill with oil upon completion of the repair operation. All parts must be washed in a cleaning fluid like High Aromatic White Spirit (Aromatic content 17-18) or equal. All o-rings and gaskets must be carefully examined for cuts or other damage. ![]() The cleaning cán be done éither by chemicals ór mechanically. Particle counting ánd water analyses évery 3 months, and full oil analyses once a year. Abnormal difference in oil level when power system is stopped or in running condition means air in the hydraulic oil (high level when power packs are stopped, low level when they are running). Vent the systém regularly until thé air is óut of the systém. Debris detectors (if installed) to be checked every 3 months. This means that the drain line to tank is contaminated by magnetic particles due to. If also thése switches have simiIar particles, the móst probable réason is contamination fróm piping, components ór oil filling. ![]() Normally this is indicated by poor stripping performance and problems related to parallel pumping.
