The work of cylinder speed control method selection techniques

Cylinder is divided into the high-speed operation and low speed operation cylinder, cylinder of the two cylinders have different using occasions, cylinder need to accurate speed control in the process of movement. Under the new western style move to introduce the cylinder under the working speed control method selection skills. Cylinder work speed of high-speed movement of the cylinder, should choose diameter of inlet pipe, the load change, can choose speed control valve or gas-liquid damping cylinder, to achieve a slow, steady speed control. Cylinder work speed is commonly - mm/s. Cylinder control valve selection considerations: requirements when the journey ends to avoid impact on the smooth movement, cylinder should be chosen with the buffer device; For large inertial load, and in the end of the cylinder stroke install hydraulic buffer or deceleration circuit design. Horizontal cylinder driving load, recommend using exhaust throttle speed regulation; Vertical installation cylinder lifting load, recommended intake throttle speed regulation. Use should be regularly check each part of the cylinder in the presence of abnormal phenomenon, the connecting parts for loose, such as the activities of the cylinder parts of the shaft pin type installation should add lubricating oil regularly. Piston work input speed depends mainly on cylinder compressed air flow, cylinder into the vent size and the size of the tube diameter. According to the work requirements and conditions, correct selection of the type of cylinder. For cylinder to travel no impact on the terminal phenomenon and impact noise should choose buffer cylinder; Light weight, requirements, choose the light cylinder; Required to install a space narrow and short journeys, optional thin cylinder; , transverse load, optional belt guide rod cylinder; Brake precision demanding, choose the lock cylinder; , do not allow the piston rod rotation, optional with functions of stem not rotary cylinder; High temperature environment to choose heat cylinder; , in a corrosive environment, need to choose the corrosion resistance of cylinder. In harsh environments such as dust, need piston rod out of the dust cover installation.
