How much do you know about cylinders?

The cylinder is used every day. When it comes to selection and application, everyone must be very familiar with it, and even can tell a lot about it. To be sure, there are some learning is neglected by myself. Today, I have specially sorted out some. Maybe you already know some, but it's no harm to learn something new from the past. Parallel cylinders should pay attention to the fact that the distance between the two parallel cylinders must be greater than 40mm, otherwise the magnetic switches of the two cylinders will interfere with each other, resulting in misoperation.
Shortening the wiring length of the magnetic switch has no effect on the function application, but if the wiring is too long, the current will be very large when the switch is turned on, thus shortening the service life of the switch. If the wiring must be very long, contact maintenance boxes must be used for more than 5 meters. Special environment use precautions, strong magnetic environment to use with strong magnetic field switch cylinder.
In places with a lot of dust and water droplets or oil droplets, a telescopic protective cover should be used on the cylinder rod side. In an environment with iron powder and iron filings near the left, if it is not protected, the magnet will absorb the iron powder and iron filings to gather around it, weakening the magnetic force in the cylinder and causing the magnetic switch to not operate. Note-the shaft of the single-axis cylinder will rotate unless it is a single-axis cylinder with anti-rotation, the shaft of the single-axis cylinder will rotate during the movement, which may cause the bolt connection of the piston rod head to be loose.
The piston rod must not be subjected to radial force. The piston rod can only be subjected to axial pushing and pulling force. Don't let the rod be subjected to lateral force if it feels thick and strong. Once subjected to lateral force, the guide rod and the inner wall of the cylinder will produce different forces., Which greatly shortens the service life of the cylinder. If there is a radial force, be sure to add a guide rod or slide auxiliary, or directly choose a cylinder with a slide and guide rod. The cylinder with its own guide rod and slide rail will be more expensive than myself, but the volume of its own is much smaller. According to the detailed status of the choice on the line.
