The speed of the cylinder

As we know, in the process of the operation of the cylinder, the rate at which it may produce a certain change, this is mainly because its at run time, because of the speed of the piston is in a state of constant change, making the speed will change accordingly. Usually, we can will be um the maximum speed of the cylinder. In fact, different buffer type cylinder, its maximum velocity at different location. If it is air cushion cylinder, such as the maximum speed of more than is in the end of the trip. If air cushion, the maximum velocity is more into the buffer before the trip. So, about the speed of cylinder, we usually is how to calculate? For this problem, we can understand it, because of its no external load, we can assume that the exhaust exhaust side for sound, at the same time air pressure reaches A certain standard, calculate the speed known as the theory reference, A formula to calculate u = * S/A, in this formula, we will u as A theory reference speed, S exhaust circuit synthesis effective cross-sectional area, A representative exhaust side effective cross-sectional area of the piston. Of course, this is concluded that the theoretical value, and the actual situation will there is a certain gap. However, when the outside world without load, very close to the theoretical value and its speed. Therefore, we think no load when the maximum velocity of cylinder can be seen as a u. When the load increases, the maximum speed will slowly decrease, usually in the calculation, the selection of its average speed. , if is to estimate the maximum velocity is about the average velocity. Times. Normally, if cylinder to ensure normal operation, the speed will remain in a range, if the speed is too small, that is the creep phenomenon. And when the speed is too large, the friction between the seals get bigger, the aging speed, serious, even there will be a flat, which affect the normal use of cylinder. Zhengzhou zhongyuan flywolf pneumatic components factory, its main products are as follows: cylinder, cylinder components, pneumatic components, pneumatic valves, solenoid valves, pneumatic fittings, pneumatic actuators, such as the diameter of the cylinder.
