The speed of the cylinder

SMC moving distance divided by the average speed of cylinder is a cylinder cylinder action time ( Usually calculated at time of arrival) 。 As cylinder using speed is refers to the average speed. When a rough calculation, the maximum speed of cylinder generally take average speed. Times. The use of standard cylinder speed range is mostly - mm/s. When the speed is less than the mm/s, due to the influence of the cylinder friction resistance increases, and the compressibility of the gas, can not guarantee the piston for smooth movement, will appear the phenomenon of the park when, referred to as the 'crawl'. When the speed is higher than the mm/s, cylinder seal friction heat production, accelerate the seal wear, cause leakage, shorten the life, also will increase, the impact of the end of the trip affect the mechanical life. Want to cylinder work under low speed, appropriate use of gas-liquid damping cylinder, or through the converter gas and liquid, the use of gas-liquid combination cylinder for low speed control. To work under the cylinder in a high speed, it is necessary to lengthen the length of the cylinder and improve the machining precision of cylinder tube, improve the sealing ring material to reduce the friction resistance, improve the buffering performance, etc.
