Scraper hydraulic system of a complete hydraulic system consists of five parts, namely, power components, actuators, control components and auxiliary components (Annex) and hydraulic oil. The role of dynamic element dynamic components of the original motivation of the mechanical energy into fluid pressure energy, refers to the hydraulic system of pumps, hydraulic automation equipment, which provides power to the entire hydraulic system. Design of the hydraulic pump gears are generally pumps, vane pumps, piston pumps and screw pumps. Action actuators actuators (such as hydraulic cylinders and hydraulic motors) is the pressure of the liquid can be converted to mechanical energy to drive the load for a linear reciprocating motion or rotary motion. Control element control element (ie the various hydraulic valves) to control and regulate fluid pressure, flow rate and direction in the hydraulic system. Depending on the control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valve comprises a pressure relief valve (safety valve), valves, sequence valves, pressure switch, etc; the flow control valve includes a throttle valve, regulating valve, flow diversion valve and the like; directional control valve includes a check valve, hydraulic control check valves, shuttle valves, valve and the like. Depending on the control, hydraulic valves can be divided off control valve, fixed value control valves and proportional control valve. Auxiliary components Auxiliary components, including fuel tanks, oil filters, coolers, heaters, accumulators, pipe and pipe fittings, seals, quick connectors, high-pressure valve, hose assembly, pressure joints, pressure gauge, oil level gauge , oil temperature meter. Hydraulic oil hydraulic oil in the hydraulic system of the working medium energy transfer, hydraulic automation equipment at home and abroad, there are a variety of mineral oil, emulsion oil hydraulic molding Hop categories. . 2 cutoff valve 3, the hydraulic automation equipment manufacturers, 8 meter hose 4. 5. 6. thermometer gauge 9. 7. relief filter parameter measurement method Step 1: measuring the pressure, first detected hose connector and double loop three-way valve threaded connections tightened on. Open valve 2, 3 relief valve shut, cutting off the oil return passage, then you can read the measured pressure points (the actual operating pressure of the system) directly from the pressure gauge. Step 2: measuring the flow rate and temperature - pressure relief valve 7 slowly release the handle, and then close the valve 1. Re-adjust the relief valve 7, so that the pressure gauge 4 reads the measured pressure value, then the 5 meter reading is the actual flow rate value of the measured point. Meanwhile thermometer 6 may show oil temperature. Step 3: measuring the speed (velocity) - regardless of pump, motor or cylinder whose speed or velocity depends only on two factors, namely, the flow rate and the geometry of its own (or displacement area), so long as the measured motor or cylinder output flow (as input to pump flow), divided by the area of ??displacement or obtain speed or speed hydraulic automation equipment, subfamily (online consultation), hydraulic automation equipment from Texas subfamily hydraulic machinery automation equipment Limited.
