The cylinder bowl is slow in the 60-6. The others are very good. Is there any solution
The hydraulic servo system is widely used in industrial control with its unique advantages such as fast response speed, high load stiffness and large power control. Electro-hydraulic servo system by using the electro-hydraulic servo valve, transforms the electrical signal of small power for high power hydraulic power, so as to realize the servo control of some heavy machinery equipment. The diagram shows an electro-hydraulic servo system that is continuously controlled for pipe flow. In the large-diameter fluid pipeline 1, the Angle theta change of valve plate 2 will be used to regulate the flow of qT. The disc rotation is actualized by the hydraulic cylinder driving gear and rack. The input quantity of this system is the given value xi of the potentiometer 5. Have certain voltage corresponding to the given value of xi, 7 loss to the amplifier, the amplifier converts voltage signal to the electromagnetic coil current signal to the servo valve, the valve core accordingly produce certain amount of opening xv. Valve opening xv allows hydraulic oil to move into the hydraulic cylinder and push the hydraulic cylinder down. The oil in the lower chamber of the hydraulic cylinder is returned to the tank by the servo valve. The downward movement of the hydraulic cylinder causes the gears and rack to drive the valve plates to deflect. At the same time, the hydraulic cylinder piston rod also drives the contact point of the potentiometer 6. When the voltage corresponding to x is the same as the voltage corresponding to xi, the difference between the two voltages is zero. At this point, the output current of the amplifier is zero, the servo valve is closed, and the hydraulic cylinder is positioned in the corresponding qT position.
Remember, there is no relationship between the speed and pressure of the hydraulic machine. Flow determines the speed, you put the cut-off valve or control valve to open a few bigger, more generally, the tube like the faucet that thing up on the road.
Whether the cylinder sealing ring is worn out, the leakage is caused, the part of the intercepting is not normally a problem, the leading part can check the stem is the card
