Why use independent variable hydraulic motor shut-off system software? Although the qualitative analysis of hydraulic motors with small specifications, low cost,hydraulic motor and high efficiency is used as much as possible, the quality management decision of the hydraulic transmission system software is based on the input terminal ( (Diesel engine + variable plunger pump) The output transmission ratio obtained by adjustment is limited by high efficiency, cost and other factors. Therefore,hydraulic motor on some mechanical equipment, you must fully consider the output end and adjust.
Generally, the output torque of the system software is sufficient,hydraulic motor and the output end is adjusted a lot to facilitate the expansion of the output transmission ratio range in the high efficiency area. What are the output adjustment methods and their characteristics? The output adjustment methods include changing the displacement of the hydraulic motor, changing the transmission ratio of the rear-camera industrial equipment gearbox,hydraulic motor and adjusting the number of hydraulic motors on the Internet.
The static four-column hydraulic controller machine equipment is mainly matched with diesel engine applications. The available gear ratio of the diesel engine is about 2~4 (for example, the transmission ratio is from 800-3000),hydraulic motor and the professional ability of variable distance near the center of the circle in high-power work is only 1.15~1.3. Therefore,hydraulic motor the available variable pitch ratio of diesel engines is an important factor in the coverage of the transmission ratio of walking industrial equipment. Variable plunger pump + qualitative analysis of hydraulic motor. The displacement of variable plunger pump varies from about 25% to 100%. After matching with the diesel engine,hydraulic motor the total variable speed ratio is about 8-16, and the total variable pitch ratio is 4-6 about.
This type of method is more suitable for small walking speeds (for example, less than 25km/h, 25/16=1.56km/h=0.43m/s, most of them can maintain low-speed gear walking),hydraulic motor and the traction rope torque change is not very Large (for example, the variation of traction rope torque is less than about 5-10 times),hydraulic motor and small walking power of mechanical equipment, such as cement floor electric forklifts, the load is changed to small forklifts,hydraulic motor small road rollers, etc. 1) Variable piston pump + independent variable hydraulic motor The displacement of the independent variable hydraulic motor varies between 40% and 100%. Therefore, the total speed ratio is about 20-40,hydraulic motor and the total variable pitch ratio is 10~ Around 15. Larger driving speed can cover about 40Km/h (40/40=1Km/h=0.28m/s,hydraulic motor most of them can maintain low-speed gear walking) mechanical equipment.
