What is Hydraulic flushing?
The objective of flushing a hydraulic system is to eliminate sludge, varnish, debris and contaminated or degraded fluid from conductor walls and other internal surfaces and system dead spots. Reasons for performing a system flush include: … Fluid degradation – resulting in sludge, varnish or microbial deposits.
How to flush an Hydraulic System?
In a perfect world, if we needed to perform a system flush, we’d have a power flushing unit available to us. Power flushing involves connecting the system to a purpose-built hydraulic power unit to circulate a low viscosity fluid at high velocities to create turbulent flow conditions (Reynolds number > 2000).
The flushing unit is typically equipped with a pump that has a flow rate several times that of system’s normal flow, directional valves, accumulators, fluid heater and chiller and of course, a bank of filters.
What is hot oil flushing?
Hot-Oil Flushing is a proven cleaning method which we now use worldwide. It gives hydraulic and/or lubrication oil systems a clean start and removes assembled debris preventing premature component failure. Hot oil circulates through (pipe) systems at very high flow rate, turbulent flow can be achieved which dislodges particles that would otherwise cling to the walls during flow. These particles are then removed from the piping as the fluid is circulated through a series of high efficient filtering systems. Our analyses are carried out in accordance with NAS/ISO.
Why carry out Hot Oil Flushing?
80% of equipment failure is proven to be a result of oil and lube system contamination. Maintaining your systems regularly reduces unscheduled down time at the lowest cost possible and also increases the lifetime of your equipment.Our “Hot Oil Flushing method” is carried out by qualified technicians using special rinsing units and analysis equipment. Naturally you receive an analysis report from us afterwards. You can therefore be certain that the desired results are met to the ISO and NAS cleanliness standards. Multinal Group provides hot oil flushing to refineries, onshore and offshore installations, production platforms and turbines, etc. It is also suitable for use in other sectors.
