دھاتی پروسیسنگ / دھات کاری

میٹلز پروسیسنگ انڈسٹریز بڑے، اہم اثاثوں کو استعمال کرتی ہیں، جن کی وشوسنییتا (reliability) ان کے کاروباری ماڈل کے لیے بالکل ضروری ہے۔ پروسیسنگ کے آلات کے ایک ٹکڑے کی غیر نشاندہی شدہ خرابی جیسے رولنگ مل گیئر باکس، یا 1000 ٹن ایکسٹروڈر پریس میں نہ صرف آلات کی مرمت اور لائن ڈاؤن ٹائم کی لاگت شامل ہے، بلکہ مصنوعات کے معیار پر بھی شدید اثر پڑ سکتا ہے۔ آج پہلے سے کہیں زیادہ، بے کارگی (redundancy) بھی کم ہے۔ تیل کا تجزیہ قابل اعتمادی پر مبنی دیکھ بھال کے پروگرام کا ایک اہم پہلو ہے، اور بہت سے بڑے سست رفتار نظاموں کے لیے، یہ تحفظ کی پہلی لائن ہے۔

Contamination of oil is big problem. Contamination can come in the form of debris and wear particles, but water can also be a critical contaminant. The cost of downtime is extremely high in metals processing plants. Therefore quick turnaround of test results is essential to keeping a plant up and running.

Wear

Particle count- a high particle count or a rapid increase in particles can foreshadow an imminent failure.

Particle composition - it is often important to understand the elemental composition of particles in order to find out where they came from. Optical Emission Spectroscopy gives the user elemental information for up to 32 elements, from Li to Ce (varies with application).

Particle type - The size, shape and opacity of particles is used to determine if they are from cutting wear, sliding wear, fatigue wear, nonmetallic or fibers. This allows operators to determine the type of wear debris, wear mode and potential source from internal machinery components.

Ferrous wear - Ferrous wear measurement is a critical requirement for monitoring machine condition. The high sensitivity magnetometer measures and reports ferrous content in ppm/ml, and provides ferrous particle count and size distribution for large ferrous particles.

Chemistry

Total Acid Number (TAN) - TAN is measured to determine the corrosive potential of lubrication oils. If the TAN gets too high the oil can induce corrosion of machine parts and should be changed.

Viscosity - The main function of lubrication oil is to create and maintain a lubrication film between two moving metal surfaces. Insuring the viscosity is within recommended ranges is one of the most important tests one can run on lube oil.

Contamination

Water- Water contamination in industrial oils can cause severe issues with machinery components. The presence of water can alter the viscosity of a lubricant as well as cause chemical changes resulting in additive depletion and the formation of acids, sludge, and varnish.
