VOITH electro-hydraulic converter DSG-B10113The mean time between failures (MTBF) exceeds 600 years.
This means that the electro-hydraulic converter has extremely high reliability, which can ensure long-term stable operation of the equipment, significantly reduce unplanned downtime, thereby improving productivity and reducing costs caused by downtime losses
The working life of DSG-B10113 electro-hydraulic converter is affected by various factors, as follows:
environmental factors：
temperatureExcessive ambient temperature can accelerate the aging of internal insulation materials in electro-hydraulic converters, reduce insulation performance, and thus affect their service life. The standard design ambient temperature for this electro-hydraulic converter is -20 to+80 ° C, exceeding this range may have adverse effects on its lifespan.
humidityExcessive humidity can accelerate the aging of internal insulation materials and may also cause rusting of metal components, reducing the reliability and lifespan of equipment. When the relative humidity exceeds 60%, the lifespan of the electro-hydraulic converter may be significantly shortened.
pollutantPollutants such as dust and corrosive gases in the air can accelerate equipment wear and corrosion. For example, air containing sulfides can accelerate the corrosion of metal materials, affecting the performance and lifespan of electro-hydraulic converters.
material properties：
insulating materialThe performance of insulation materials directly affects the lifespan of electro-hydraulic converters. High performance insulation materials have low dielectric loss and good heat resistance, which can effectively improve the reliability and service life of equipment.
metal materialThe mechanical properties such as tensile strength, yield strength, hardness, and corrosion resistance of metal components in electro-hydraulic converters, such as control pistons and valve cores, have a significant impact on the lifespan of the equipment.
Operating conditions：
workloadLong term overload operation can cause an increase in internal temperature of the electro-hydraulic converter, accelerate material aging, and shorten its service life. Its input pressure can reach 70 bar. If the actual working pressure exceeds the rated value for a long time, it will cause damage to the equipment.
electromagnetic interferenceElectromagnetic interference can have adverse effects on the electronic control part of electro-hydraulic converters, leading to unstable equipment operation and shortened lifespan.
Vibration and ShockIntense vibration and impact can cause the internal components of the electro-hydraulic converter to loosen and wear, affecting its performance and lifespan.
maintenance：
regular inspectionRegularly inspecting the electro-hydraulic converter can promptly identify and address potential issues such as wear and looseness of components, prevent equipment failures, and extend its service life.
Cleaning and lubricationKeep the electro-hydraulic converter clean to prevent dust and pollutants from entering the interior, while proper lubrication can reduce friction between components and lower wear.
Maintenance qualityHigh quality maintenance can ensure the normal operation of the electro-hydraulic converter and extend the service life of the equipment. If not properly maintained, it may lead to a decrease in equipment performance or even malfunction.
