Savings potential for hydraulic plants with ADDINOL HV Eco Fluid
Hydraulic systems of modern injection moulding machines pose ever increasing demands on hydraulic fluids. Some years ago hydraulic oils of type HLP used to be standard; nowadays advanced products with improved temperature as well as friction behaviour are applied more and more often. ADDINOL Lube Oil GmbH, Leuna, offers HV Eco Fluid – a hydraulic fluid which increases the efficiency of hydraulic systems and decreases the energy consumption of plants. In long-term tests, i.e. in an injection moulding machine, the operator could prove savings of up to 5 % together with ADDINOL. Stationary hydraulic plants are being applied in almost all industrial sectors. One typical application calling for high performance and absolute precision are injection moulding machines in plastics industry. Efficiency and compactness of such machines are increasing, they are supposed to be available all the time and to achieve reduced tolerances and improved surface qualities. This in turn means increased requirements on the hydraulic fluids which transmit forces, lubricate and protect. Conventional hydraulic fluids are more prone to ageing Smaller oil volumes, higher pressures and rising operating temperatures are extreme operating conditions requiring more than conventional hydraulic fluids. Furthermore, all lubricants and hydraulic fluids are subject to ageing during their application which means they react with oxygen. Oil ageing means a decrease of performance and an increase of viscosity which has direct effects on the efficiency of the pump. Thus stable viscosities over the whole operating period are expected because they influence the overall efficiency of the pump and energy consumption. Pressure build-up necessary for the operation of the injection moulding machine is not effected as required, the hydraulic fluid needs to be changed and shorter operating intervals increase the costs. Increased efficiency – reduced energy consumption The innovative hydraulic oil ADDINOL HV Eco Fluid is based on high-grade mineral oils and a special additive technology. It meets DIN 51524/3 (HVLP), DIN EN ISO 6743-4 (HV), ISO 11158 (HV), AFNOR NFE 48603 (HV), CETOP RP 91 H (HV) as well as requirements of all leading OEM. Compared to conventional HVLP, HV Eco Fluid achieves a higher efficiency of the hydraulic altogether which means: higher power under full load, faster reaction of the system and decreased energy consumption. Proven cost reduction In order to prove the performance and the reduced energy consumption under practical conditions ADDINOL documented the application of HV Eco Fluid 46 in an injection moulding machine. The plant of type Krauss-Maffei 650 (6.50 kN clamping force) is operated by a well-known company in the plastics industry producing parts for automobile industry such as handle bars and covers for engine compartments. Operating hours per year amount to roughly 7,500 hours; oil filling is 1,500 litres. Before, conventional hydraulic oil HLP 46 had been used. During application the operator of the injection moulding machine measured and documented energy consumption. Before and after the oil change the same kinds of injection moulding parts were produced by the machine. For both parts energy consumption under constant conditions (identical cycle times etc.) was determined and calculated for every piece moulded. In the time monitored the same number of parts was manufactured. Therefore the energy consumption per injection moulding part could be determined very exactly. Ten months after the start the notes were analysed for the first time. For the operation with ADDINOL HV Eco Fluid 46 energy consumption was reduced by 4.8 % which resulted in a significant reduction of operating costs. The fluid has been applied since February 2009 without any failures or problems. Energy consumption is still measured to monitor the product’s sustainability over longer periods – with positive results.
