Technical field

The present invention relates to hydraulic speed regulation system technical field, specially a kind of Modular Flexible hydraulic speed regulation system.

Background technique

The effect of hydraulic system is to increase active force by changing pressure.One complete hydraulic system is by five part groups At i.e. dynamical element, executive component, control element, auxiliary element (attachment) and hydraulic oil.Hydraulic system can be divided into two classes: liquid Press transmission system and hydraulic control system.Hydraulic Power Transmission System is to transmit power and movement as major function.Hydraulic control system Hydraulic system output is then set to meet specific performance requirement (especially dynamic property), usually said hydraulic system is main Refer to Hydraulic Power Transmission System.

One complete hydraulic system is made of five parts, i.e. dynamical element, executive component, control element, auxiliary member Part (attachment) and hydraulic oil.Dynamical element, the effect of dynamical element are that the mechanical energy of prime mover is converted into the pressure energy of liquid, Refer to the oil pump in hydraulic system, it provides power to entire hydraulic system.The structure type of hydraulic pump generally has gear pump, blade Pump, plunger pump and screw pump.Executive component, the effect of executive component (such as hydraulic cylinder and hydraulic motor) are by the pressure energy of liquid Mechanical energy is converted to, straight reciprocating motion or rotary motion are made in driving load.Control element, control element (i.e. various hydraulic valves) Pressure, flow and the direction of liquid are controlled and adjusted in hydraulic system.According to the difference of control function, hydraulic valve can be divided into pressure Force control valve, flow control valve and directional control valve.Pressure-control valve includes overflow valve (safety valve), pressure reducing valve, sequence valve, pressure Power relay etc.；Flow control valve includes throttle valve, adjustment valve, flow divider-combiner etc.；Directional control valve includes check valve, hydraulic control Check valve, shuttle valve, reversal valve etc..According to control mode difference, hydraulic valve can be divided into bang-bang control valve, setting control valve and ratio Example control valve.Auxiliary element, auxiliary element include fuel tank, oil filter, cooler, heater, accumulator, oil pipe and pipe fitting, Sealing ring, quick-release connector, high-pressure ball valve, hose assembly, pressure measuring tie-in, pressure gauge, oil level indicator, oil thermometer etc..Hydraulic oil, it is hydraulic Oil is the working media that energy is transmitted in hydraulic system, there is several major class such as various mineral oil, emulsion and Synthetic Hydraulic Oil.
