Hydraulic oil is the working medium that transfers energy in the hydraulic system. Auxiliary componentsĪuxiliary components include fuel tanks, oil filters, coolers, heaters, accumulators, oil pipes and pipe joints, sealing rings, quick-change joints, high-pressure ball valves, hose assemblies, pressure measuring joints, pressure gauges, oil level gauges, Oil thermometer, etc. According to different control methods, hydraulic valves can be divided into on/off control valves, fixed value control valves and proportional control valves. Directional control valves include check valves, hydraulic control check valves, shuttle valves, reversing valves, etc. Pressure control valves include safety valves (safety valves), pressure reducing valves, sequence valves, pressure relays, etc.įlow control valves include throttle valves, regulating valves, diverting and collecting valves. According to different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Control componentsĬontrol components (ie various hydraulic valves) control and regulate the pressure, flow and direction of the liquid in the hydraulic system. The function of the executive components (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy and drive the load to perform linear reciprocating or rotational movement. The structure of hydraulic pumps usually includes gear pumps, vane pumps, plunger pumps and screw pumps. The pressure energy refers to the oil pump in the hydraulic system, which provides power for the entire hydraulic system. The function of the power element is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. The complete hydraulic system of pond dredge for sale includes five parts, namely power components, executive components, control components, auxiliary components (accessories) and hydraulic oil. The hydraulic system is a systematic project, which is highly professional and comprehensive. The hydraulic system of the Leader dredger is distributed throughout the dredger and is the core control system of the entire ship.
