The Working Principle Of Hydraulic Transmission Of Hydraulic Winch

               The hydraulic system consists of a complete hydraulic system mainly composed of the following five parts; 1 power Plant it supplies the pressure of hydraulic system, and the mechanical energy of the output of the motor is converted to the pressure energy of the oil liquid, which pushes the whole hydraulic system to work. As the figure in the hydraulic pump 3 is the power plant, the oil from the tank 1 suction people, and then to the system. 2) executing component; it includes hydraulic cylinder and hydraulic motor, used to convert the pressure of the liquid into mechanical energy to drive the movement of working parts; Fig. 8 is a hydraulic cylinder, driven by pressure oil, drive the grinder worktable to do straight-line movement; 3 The control device includes a variety of valves, such as pressure valve, flow valve and directional valve. Used to control the fluid pressure, flow rate, and flow direction of the hydraulic system to ensure the completion of the desired working motion of the component. Fig. 5 is the overflow valve, used to control the pressure of the system, 4 is the throttle valve, used to enter the flow of the hydraulic cylinder, thereby controlling the movement speed of the worktable; 6 is the reversing valve, used to change the pressure oil path, so that the hydraulic cylinder reversing, to achieve the reciprocating work table 4 auxiliary device refers to a variety of fittings, tubing. Tanks, Shan and pressure gauges. They play an auxiliary role such as connection, storage, filtration, storage pressure and measurement of oil, to ensure reliable hydraulic system. Work stably and lastingly. Figure 2 is a net filter. The role of filter oil; 1 is the fuel tank, used for oil storage and heat dissipation. 5 The working medium refers to the fluid which is under pressure and transmits pressure in the hydraulic system.Hydraulic Winch

              The working principle of hydraulic transmission as shown in the figure of the grinder table hydraulic transmission schematic diagram, hydraulic pump 3 by the motor-driven, from the tank 1 oil suction, and then the pressure can be transported to the oil pipeline, oil through the throttle valve 4 and pipe flow to the reversing valve 6, reversing valve 6 of the spool has a different working position (the figure has three working positions), so the path is different, when the spool is in the middle position, the valve port p. A, B. T is mutually interlinked. The oil circuit leading to the hydraulic cylinder is blocked, and the hydraulic cylinder does not pass the pressure, so the worktable stops moving; If the spool is pushed to the right (right side of the working position), then the valve port P and a, B and t are interlinked, the pressure oil flows through the p mouth to the directional valve 6, through a mouth into the hydraulic cylinder 8 of the left cavity, the piston 9 in the hydraulic cylinder left cavity pressure oil pushing the worktable 10 to the right; the fluid in the right cavity of the hydraulic cylinder flows into the reversing valve through the B of the reversing Valve 6 6, and then back to the oil port T flow back to the tank 1; If the valve core of the reversing Valve 6 is pushed to the left ( Left working position), the piston drives the worktable to the left; therefore the reversing Valve 6 's work position is different, can change the pressure oil The path unceasingly, causes the hydraulic cylinder to be reversing unceasingly, realizes the work table the reciprocating movement which needs.Hydraulic Winch

             According to the different processing requirements, the moving speed of the worktable can be adjusted by the throttle valve $number to adjust the flow through the throttle valve by changing the orifice size of the throttle valve to control the moving speed of the worktable. Table movement, due to different work conditions, to overcome the resistance is different, the different resistance is by the hydraulic pump output oil pressure can be overcome, the system pressure through the overflow valve 5 regulation. When the oil pressure in the system rises above the pressure of the overflow valve, the steel ball on the overflow valve is opened and the oil is discharged back into the tank by the overflow valve. At this time the oil pressure no longer rises, maintain the value. In order to maintain the Pujie of the oil, the filter is set up to remove the impurities in the oil liquid and the system works normally. In short, the working principle of hydraulic transmission is to use the pressure of the liquid to transmit power, the use of actuators to the liquid pressure can be converted to mechanical energy, the movement of working parts. The liquid positive system works, must control and adjust the oil pressure, the flow, the direction, satisfies the work component in the force, the speed and the direction request.Hydraulic Winch
