Carlube Flushing Engine Oil 4.55 Litres

Product Information

Charged Particle (Electrostatic) Separators—Some suppliers have demonstrated success at removing varnish from machine surfaces and stripping out submicron soft contaminants that can contribute to varnish and sludge. Each flushing loop should be unique and traceable. Create individual drawings or use suitable piping and instrumentation diagrams (P&IDs). Mark position of sampling points for temperature, flow and oil samples. Use large duplex filters (Beta 3= 200 or higher) with differential pressure indicator to allow filter changing without interrupting flushing. If water removal is desired, include a filter with water-absorbing capabilities. Typically, for chemical flushes an oil soluble solution composed of naphthenic base with detergents, dispersants and corrosion inhibitors is added to the in service turbine oil, sometimes water based fluids with cleaners are used as well. The treat rate is approximately 10% used at 48 hours before the outage. Supplemental filtration is required during the flush to accommodate the increased volume of contamination released. After the in-service oil and cleaner are drained from the system, there must be a sacrificial flush to rinse the remaining cleaner from the system. Quite often, multiple charges of the flushing oil may be used to dilute the cleaner in the system and minimize the impact on the new oil.

ENGINE FLUSHING. IS IT EVEN WORTH IT AND IF YES - Castrol

Special flanges, manifolds and connectors may be needed to assemble the components to be cleaned in series. Flush the system with a lower viscosity fluid that is similar to the fluid to be used. A Reynolds number between 2,000 and 4,000 should be selected to achieve enough turbulence to remove particles from the lines. Stroke valves frequently to ensure they are thoroughly flushed. The fluid should be filtered and the flushing should continue until reaching one level beyond the system’s target cleanliness levels. For example, if the target is ISO 15/13/11, continue to flush the system until ISO 14/12/10 is reached.

For new or rebuilt machines to remove contamination resulting from manufacture, service or overhaul. The fluid system can be contaminated due to dirty assembling elements, corroded surfaces, water, oxidation products and incompatible elastomers such as seals, sealants and coatings. Also, during the assembly process, dirt is ingested and debris is generated due to threading, joining, welding, etc. Just because the changeover has been completed does not mean that you are “out of the woods.” Your system will need to be closely monitored for a while to make certain that the flushing was thorough. Taking the time to verify that the system is fully flushed and purged of the old fluid prior to introducing the new fluid will go a long way toward ensuring a healthier hydraulic system. This might not apply to every engine flush, but it applies to AMSOIL Engine and Transmission Flush. It delivers results after just one application. And it only takes 10-15 minutes to use. In normal conditions, a water-absorbing filter should be sufficient, assuming the moisture levels are low. Certain synthetic fluids must be dehydrated with oil purifiers.

Contaminants circulating throughout the engine can lead to oil breakdown and increased viscosity – and higher-viscosity oil requires more energy to circulate throughout the engine. Ten percent of the old contaminated or depleted lubricant may be enough to use up most of the additives of the new oil. This enables flushing decisions to be made or modified in real-time in response to oil analysis data. In addition to laboratory testing of oil samples, various inspections of the machines’ internal surfaces, including gearing, bearings, and tanks, can help confirm the successful execution of the flush program. As seen in Figure 1, turbulence can have a significant influence on loosely attached solid debris lingering in crevices or in the sidewall perimeter low-flow area. Turbulence in the system shortens the time and improves the quality of the flushing activity. To properly achieve particle removal, the fluid must be turbulent. The indexless Reynolds number measures turbulence. In general, a number greater than 4,000 represents turbulent flow, and a number less than 2,000 represents laminar flow. Hydraulic and circulation system designers strive to create laminar flow conditions. For gearbox and bearing housings fed with a central system, turbulence is necessary. For stand-alone housings, the effect of turbulence and the ability to direct the force of the fluid facilitates movement of soil.

Factors for Effective Flushing

Although the situations above may induce the reader to perform a flush between every oil change, there are times when no flush is required between oil changes. Here are those instances that do not require a flush between oil changes: Many flush strategies involve the use of a program of flush tactics until the original offending contaminant has been scoured from the machine as well as both the flush and rinse fluids. The flush and rinse fluids often contain fluid chemistry that must be thoroughly removed before the lubricant is replaced and the machine is returned to service. Power flushing - A variation of recirculation, where the oil level in the sump is reduced and a high-velocity fluid is applied to mechanically dislodge, lift and entrain particulate debris. Power flushing suspends and transports particles; absorbs air, chemical products and water from the system; and releases the contaminants to a filter. 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.
