In order to increase the load capacity of construction machinery, direct way is to increase its hydraulic system pressure, flow and power. Currently, advanced engineering machinery products rated international pressure, mostly in more than 30 MPa, and with advances in materials science and technology, there are toward the higher pressure even using high pressure hydraulic technology trends in the direction of development; flow rate per minute is usually Hundreds of liters; power over hundreds of kilowatts. Such as Germany Orensttein && Koppe made the world's first largest RH400 full hydraulic excavator bucket capacity of 42 m3, hydraulic oil source for the variable displacement axial piston pump 18, the total flow of up to 10 200 L / min; prime mover of 2 QSK60 diesel engine, repair of the hydraulic motor, the total power of up to 2 014 kW. Standard curve folded edit this section is to avoid the influence of other factors, often measuring a series of standard solutions of different concentrations of the substance in a certain wavelength absorbance. In the vertical axis represents the absorbance or transmittance, the horizontal axis represents the concentration to a standard curve, the hydraulic motor is mounted, for quantitative determination routine. In the quantitative measurement, select the appropriate wavelength for the quantitative determination of important horizontal hydraulic motor for sale, commonly used absorption peak of the absorbance band. With a relatively flat absorption peak at a certain wavelength range, the hydraulic motor, small changes in the absorption intensity by other factors such as small slots and other interference, so the error is also small.
