Cylinder product series
Japanese SMC standard cylinder, the inner surface of the steel tube cylinder should also be plated with hard chromium to reduce frictional resistance and wear. And can prevent rust. In addition to using high-carbon steel pipes, the cylinder barrel material is also made of high-strength aluminum alloy and brass. Some small cylinders use stainless steel tubes. For cylinders with magnetic switches or cylinders used in corrosion-resistant environments, the cylinder barrel should be made of stainless steel, aluminum alloy or brass.
There are many types of buffer devices installed in SMC cylinders. The above is just one of them. Of course, measures can also be taken on the pneumatic circuit to achieve the purpose of buffering. Combined cylinders generally refer to gas-liquid damping cylinders, gas-liquid boosting cylinders, etc. formed by the combination of cylinders and hydraulic cylinders. As we all know, the working medium usually used in cylinders is compressed air, which is characterized by fast movement, but the speed is difficult to control. When the load changes greatly, it is easy to "crawl" or "self-propelled";while the working medium used in hydraulic cylinders is It is generally considered that incompressible hydraulic oil is characterized by not being as fast as the cylinder, but the speed is easy to control. When the load changes greatly, appropriate measures are taken, and generally "crawling" and "self-propelled" phenomena will not occur. The clever combination of air cylinders and hydraulic cylinders, complementing each other's strengths, has become a commonly used gas-liquid damping cylinder in pneumatic systems. The working principle of the gas-liquid damping cylinder is shown in Figure 42.2-5. In fact, the cylinder and the hydraulic cylinder are connected in series, and the two pistons are fixed on the same piston rod. The hydraulic cylinder does not need a pump to supply oil, as long as it is filled with oil, a hydraulic check valve, a throttle valve and an oil replenishing cup are installed between the inlet and outlet. When the right end of the cylinder is supplied with air, the cylinder overcomes the load and drives the hydraulic cylinder piston to move to the left (the left end of the cylinder is exhausted). At this time, the left end of the hydraulic cylinder drains the oil, the one-way valve is closed, and the oil can only flow into the right chamber of the hydraulic cylinder through the throttle valve and In the oil cup, if the throttle valve port is opened wide at this time, the oil will be discharged from the left chamber of the hydraulic cylinder smoothly, and the two pistons will move faster. On the contrary, if the throttle valve port is closed small, the oil will be discharged from the left chamber of the hydraulic cylinder. If blocked, the movement speed of the two pistons will slow down. In this way, by adjusting the opening size of the throttle valve, the movement speed of the piston can be controlled. It can be seen that the output force of the gas-liquid damping cylinder should be the difference between the force (thrust or pulling force) generated by the compressed air in the cylinder and the damping force of the oil in the hydraulic cylinder.
