by working closely with a manufacturer of hydraulic pumps and motors, the ningbo zhongyihas optimised a number of bearings used in sauer-danfoss' newly developed h1 series of axial piston pumps and motors.ningbo zhongyi hydraulic motor co., ltd has any years of expereince about hydraulic motor, piston motor, hydraulic winch, pg电子下载-pg电子游戏 hydraulic steering,axial piston motor etc all kinds of motor production experience, quality assurance, welcome to choose our product.
as a result of the new optimised x-life cylindrical and tapered rolling bearings, overall efficiencies of the h1 pumps and h1 motors have increased by around 2 per cent, resulting in significant improvements in energy efficiency levels across the h1 range.
energy saving potential for the end users of the pumps and motors is significant. for example, by utilising a new h1 hydraulic pump and two h1 hydraulic motors, a wheel loader that has a drive power of 140kw can save around 9kw. projected onto 1,000 wheel loaders operating for eight hours a day, annual savings potential could reach 26,000mwh. this is equivalent to the average energy consumption of more than 6,500 households with three occupants.
this results in approximately 5 million euros (0.21 euros/kwh) or around 16,000 tonnes of co2 per year that can be saved. the latter is approximately equivalent to the annual emissions of 4,200 compact sized cars, each traveling 25,000km per year.
increasingly stringent emissions regulations and rising energy costs are boosting demand for more efficient machines and drive systems, including the optimisation of power train designs for diesel engines in order to reduce vehicle fuel consumption.
