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...

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...

Two different system modelling can be distinguished in life cycle assessment: attributional and consequential. Attributional modelling is used to describe the present state of the examined system and is characterised with use of allocation, no substitutions, market average suppliers, and cut-off principle. Consequential modelling is used to describ...

Production planning and control, as one of the managerial responsibilities in any production industry, have become increasingly complex during the last few decades particularly in the SME`s. Shortening of lead-time has been addressed as a major competitive edge. This paper presents the CAE approach to arriving at PPC decision in a SME`s for furnitu...

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...

Waste water is taken from the place of origin to the receiver with the prior treatment of sewage consisting of a set of pipes, canals and structures. Sewerage is done by domestic (sanitary) and industrial wastewater.Treatment (conditioning) of wastewater is a procedure for reducing pollutants to those quantities or concentrations by which purified ...

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...

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...
