Generally speaking, the required cleanliness level to target during flushing is half the level during normal operation. For example, if the normal operation level is ISO 15/13/11, flush to an ISO14/12/10. Requirements for cleanliness levels of both solid particles and moisture should be achieved. Special flanges, manifolds and connectors may be needed to assemble the components to be cleaned in series.

Carlube is the UK's largest independent producer of oils for the automotive industry, offering an extensive range of lubricants to meet the ever changing demands of modern vehicles. Authorize a technical specialist to manage and approve the performance and documentation of flushing procedures. The specialist should also handle cases of procedure deviation from suppliers. The authorization should be independent of discipline with respect to technical and commercial departments (piping, instrumentation, purchasing, etc). Do you need to change the gearbox oil? I thought modern cars do not need this doing. I've never changed gearbox oil in any car and never had a gearbox problem.As such, for a period after a flush, oil analyses should be performed regularly on critical machinery to ensure that healthy conditions have been restored. Early detection of a problem could be the difference between costly downtime and a nuisance condition that could have been easily corrected. There is some risk associated with the high-velocity flush. Circulation of a fluid at high velocity with particulate contaminants can damage sensitive components (pumps, heat exchangers and valves). Also, such high pressures and flow can affect system filters. It is necessary to bypass flow- or contaminant- sensitive components. Resikonya bila saluran pelumasan tersumbat, mesin bakal overheat bahkan bisa ngejam lantaran gesekan komponen bergerak di dalam mesin tidak terlumasi dengan baik.

Develop a plan for how to systematically control hook-up of subsystems into the main system. The important issue is to prevent spreading infections between systems. Document results as part of the total flushing procedure.Filter housings can be left in place if filter elements are removed. Components that restrict the flow rate, and thereby increase the pressure drop, should be isolated from the flushing circuit and cleaned individually. The system assembler must clean these components according to specified procedures if cleanliness certificates are not available from the supplier. Cleanliness certificates should not be considered valid if the cleaning has not been performed to these requirements.

To ensure proper cleaning is achieved in all parts of the system and to avoid damage to sensitive components, certain parts should be by-passed or dismantled during cleaning. Each component or subsystem should be cleaned to the required cleanliness level as a part of a flushing circuit or in separate circuits. Partitioning of the overall system is typically needed to achieve this. The flushing fluid should be compatible with the fluid used during normal system operation as specified by the client. The viscosity of the fluid at different temperature levels should be specified. As a guideline, standard flushing units normally provide sufficient turbulent flow if the viscosity is in the 10 to 15 cSt range at 104°F (40°C). Ideally, the flushing fluid should obtain that viscosity at no higher than 158°F (70°C).

The fluid temperature should be monitored and controlled to verify that the oil viscosity provides sufficient turbulent flow in all parts of the flushing loop and at values within the specification for the actual flushing pumps.
