FORGING QUALITY IN THE FUNCTION OF THE CONSISTENCY OF THE TOOLS IN THE PROCESSING OF THE WHEEL SLEEVES OF MOTOR VEHICLES
Bearing in mind that the wheel sleeves of motor vehicles are exposed to strong dynamic loads, and knowing that these are very responsible parts of the constructions, the need for permanent researches of the influence of certain variables on the process of production of them is imposed. The prepared part which, in this case, is obtained by forging f...

FRACTURES OF METALLIC PARTS
The fracture of a part or element of a construction can also be defined as a macroscopic separation of the material that leads to the loss of a solid body load. The fracture is the end result of plastic deformation and occurs when all the potential of the material in terms of elastic and plastic deformation is exhausted. This is the worst case of e...

HOW TO DETERMINE THE CAUSE AND SOURCE OF HYDRAULIC OIL VARNISHING
While performing ordinary oil condition monitoring on industrial systems, we can often notice that hydraulic oil has changed its color. The source of the problem can be very difficult to locate and is often consequence of complex chemical processes in hydraulic oil. Finding the root cause of oil varnishing in hydraulic machine design and its operat...

ANALYSIS OF WATER EVAPORATION IN TWIN SCREW COMPRESSORS USING CFD
Twin screw compressors are extensively used in applications which require pressures higher then allowable pressure in oil free compressors but would benefit from oil free operation such as food processing, pharmaceutical industry etc. The major limitation for achieving high pressures is due to prohibitively high temperature increase in oil free ope...

FINDING THE ACTUAL CAUSES OF HYDRAULIC CYLINDER FAULT
Hydraulic cylinder malfunctions are very common causes for the failure of the operation of the hydraulic system. Most common causes are in cylinder’s seal failure, whereby the error by replacing the seals can be relatively quickly eliminated. In the case of frequent occurrence of the same failure, the problem should be more carefully addresse...

QUALITY TESTING OF THE OPERATING MACHINES CABINS
The basic objective of machine structure testing is to reduce the number of structures without satisfactory quality, which are either discarded as scrap or sent for additional machining. The non-destructive testing can detect surface and internal errors in structures, depending on the applied testing method, which enables total quality of the produ...
