Transcription

1 ir Cooler Mobile C-LNH 8-1 with hydraulic motor Symbol General The C-LNH air cooler series is designed specifically for mobile hydraulic systems where high performance and efficiency are required and physical size must be minimized to allow easy installation. Product Features C-LNH coolers use a combination of high performance, pressure-resistant cooling elements and hydraulic drive motors in order to ensure long, troublefree operation of hydraulic systems in the mobile sector. l Compact, efficient, high performance l Cooling range kw l Hydraulic motors from 6.3 to 22 cm³/rev pplication Field Gearbox cooling and hydraulic systems in all mobile machines and vehicles, such as l Mobile cranes l Concrete mixers and pump trucks l Road paving machines l Construction machines (excavators, wheel loaders) l gricultural machines l Municipal machines Operation data Fluids Viscosity Temperature range Pressure resistance of the cooling element Fan Motor* Noise levels ccessories * Calculation of the required oil volume: V g x n Q = [l /min] 10 3 x η vol l Oils (mineral oils, synthetic oils, high viscosity oils, biological oils, phosphate ester) l Water glycol (cooling fluid) 2,000 mm²/s (standard) l Minimum / maximum ambient temperature: -20 C to +0 C (standard) l Maximum temperature of the medium: +130 C Please contact the technical sales department in the event of deviating temperatures. Notice! Fan switching frequency at max. fan speed (max. volume of air) must be avoided when operating a cooler at which the temperature difference between the medium inlet at the cooler and the ambient temperature can be greater than +50 C. Quick changes in the temperature of the cooling element material can lead to a significant reduction in service life or to direct damage of the cooling element due to thermal shock. Please contact the technical sales department to receive information about controlled fan drives. l Dynamic operating pressure: 16 bar l Static operating pressure: 21 bar xial fan in suction version (standard) xial fan in blowing version on request (note: approx. 10 % less cooling capacity) Hydraulic l motor Reversible direction of rotation l max. outlet side pressure: 150 bar l max. drain pressure: 5 bar l max. operating pressure: 6.3 / 1 cm³/rev = 300 bar, 22 cm³/rev = 20 bar l Operating fluid: Mineral oil to DIN 5152/25; DIN51511 Viscosity range: mm²/s (recommended mm²/s) Temperature range: up to + 80 C Filtration: ISO/DIS 06, Class 19/17/1, β bar, Class 21/19/16, β 25 < 10 bar See Technical Data. The noise levels are only reference values as the acoustic properties of a room, connections and reflection have an effect on the noise level. l Integrated pressure bypass valve (IBP) or integrated thermal pressure bypass valve (IBT) (cannot be retrofitted, also see Options) l Thermostats l ir filter grid or air filter mat l Vibration damper V g = motor displacement [cm³/ rev] n = fan speed [rpm] η vol = volumetric efficiency = 90 % at operating pressure of 150 bar (Calculation also possible in simulation software KULI) 1

2 Options Integrated pressure bypass valve (IBP) / Integrated thermal pressure bypass valve (IBT) The bypass channel is integrated in the cooling element. If a particular pressure is exceeded, the IBP opens the bypass channel, thereby protecting the cooling element from too high a pressure. Furthermore, the IBT only opens the cooling element path once a particular temperature has been reached. TEX The C-LNH is also available for operation in gas and dust explosive areas. Corrosion protection CPL The CPL version (Corrosion Protection Level) is suitable for aggressive ambient conditions, such as industrial atmospheres, high humidity or high salt content, which place great demands on the corrosion resistance and robustness of the materials used. Thermal bypass hydraulic motor / variable speed The thermal valve is a pilot-operated pressure relief valve with temperaturedependent pressure control and is mounted on the hydraulic motor instead of the provided end cap. The pressure setting of the valve automatically changes depending on the temperature and thus controls the motor speed. In addition to the actual temperaturecontrolled pressure setting, maximum pressure relief and a recharging valve are fitted as a bypass check valve. The setting temperature values can be from +0 C to +70 C and the pressure can be controlled up to +100 C. Please contact us for the designing of the thermal valve. ll hydraulic motors can be equipped with thermal bypass. The minimum oil pressure at which the valve starts to work is 8 bar, i.e. this must be taken into consideration for the rest of the operating pressure range of the motor.
