| Hydraulic and pneumatic supercharging cylinder pressure system theory | Hydraulic and pneumatic supercharging cylinder type hydraulic transmission principle of work, grinding machine, hydraulic transmission principle diagram worktable pump by motor driving, from the fuel tank in oil absorption, then the oil pressure is transported by throttle valve and pipe, oil pipe flow to the directional control valve, reversing valve valve core.the have different working position (three working location), therefore, when access valve core position in the middle, the mouth. P.A.B.T to each of the hydraulic cylinder, hydraulic cylinder by removing all oil pressure oil, so the workbench couldn't stop. If the valve is the core to the right place at the right job push (at), and A mouth valve, B and P T, pressure oil shed by P mouth by A directional control valves, into the hydraulic cylinder piston left, left in the hydraulic cylinder pressure oil of workbench drive to the right, Hydraulic cylinder of oil by right of the directional control valve b into the mouth, and the directional control valve oil tank; T flow back mouth, If the valve spool directional control valve to push (left), piston driven work position to the table, Thus reversing valve work position different, can change the oil pressure, hydraulic cylinder access constantly, in order to realize the commutation of workbench need reciprocating motion.
According to the different requirements of the processing speed, working through the throttle to adjust, change the size of the opening by the throttle to adjust the flow through the throttle valve to control the movement of workbench.
Table motion, due to the different work conditions, to overcome the resistance is different, the resistance is different from the oil pump output pressure to overcome the pressure of the system through the overflow valve adjusting. When the system pressure to seek higher than the set pressure relief valve discharge valve, the ball is open, the relief valve row back oil tank. Now no longer increases, maintain pressure setting value.
To keep the oil PuJie Settings, the dirt, oil filter system impurities working normally.
Anyhow, hydraulic transmission working principle is to use the liquid pressure to transfer power, Using the liquid pressure components can convert energy, drive working parts movement. Hydraulic system, it is necessary to work is oil pressure, flow, direction control and adjustment, to meet the work parts in strength, speed and direction. |
