Lubrication is a prime requirement for all steam turbines, compressors, pumps, turning equipment or hydraulically operated plants as it adds to the life and efficiency of the machine by reducing wear and tear of its parts. The lubricating oil forms a thin film of oil between the moving shaft and its bearing which

results in lesser friction and correspondingly less heat generation at the shaft, thereby keeping the working temperature of machine parts within safe operating limits.

Bearings are made of a lead, antimony and tin; copper, tin, and lead; or copper and lead depending upon their use. These are soft surfaces that are very susceptible to damage.

So these lube oil systems must be very clean before these systems are put in service. This is where our oil flushing services are needed.

SYGMA flushing systems are flexible – engineered & configured for specific purpose to cause cavitating flow, which fluidizes particulate matter and pumps the flushing fluid through an advanced filtration system. Carbon steel systems can be chemically cleaned prior to oil flushing in order to assure optimum cleanliness.

Flushing coupled with online oil analysis to ensure that the level of system cleanliness meets hydraulic component and system specifications will lead to extended system life.

Maintaining flow parameters are very important in oil flushing. For lube oil flushing of any systems, SYGMA engage detail engineering to develop turbulent flow through all the loops, branches with velocity of 5 to 10 meters per second. The turbulent flow will sweep out the particles that collect along the boundary layer of the pipe by the turbulent flow’s diffused patterns. This principle is even more important in oil flushing when system oil, a more viscous fluid than flushing oils, is used in the circulation loop. Under these conditions a higher flow rate plus heating the oil will be needed to lower oil’s viscosity. The combination of these procedures, coupled with an advanced filtration system, produces a clean system that will meet or exceed the most stringent particle count criteria set for lubricating, seal and hydraulic oil systems.

SYGMA oil flushing methods complying with major standards – SAE (Society of Automotive Engineers, Inc.), ISO (International Standards Organization) and NAS (National Aerospace Standard). The typical class that we flush to is NAS 7 or ISO 16/13.
