The following points should be paid attention to when using the cylinder.

(1) According to the requirements of the work task, choose the cylinder structure, installation mode and determine the size of the piston rod thrust and tension.

(2) In order to avoid frequent impact between piston and cylinder cover, it is generally not recommended to use full stroke, and the stroke margin is 30-100mm.

(3) When using the air cylinder actuator, it should conform to the normal working conditions of the cylinder, so as to achieve better results. These conditions include working pressure range, pressure resistance, ambient temperature range, usage speed range, lubrication condition, etc.

(4) The assembly is to apply grease on the surface of the relative motion of all seals; pay attention to the direction of action, the piston rod can only bear the axial load; the piston rod does not allow the eccentric load or the lateral load, and the cylinder should not leak out when the cylinder is tested under the pressure of 1.5 times. When installing, ensure that the load direction is consistent with the cylinder axis. When the YX - shaped seal is installed, the installation direction should be paid attention to.

(5) To avoid large collision at the end of the stroke, avoid damaging the mechanism or affecting the accuracy of the cylinder. In addition to the selection of buffer cylinders, additional buffering devices can be used generally.

(6) All air cylinder actuator should be lubricated except that they are not lubricated with oil.

(7) If the pneumatic equipment is idle for a long time, it should be operated and maintained regularly, or the cylinder should be removed and oiled to protect against corrosion and damage.

(8) After the air cylinder actuator is dismantled, the cylinder barrel, piston, piston rod and cylinder head should be cleaned first to remove rust, dirt and dust particles on the surface.

(9) The selected lubricating grease can not contain solid additives.

(10) The sealing material is determined according to the working conditions, the best choice of polytetrafluoroethylene, the material friction coefficient (0.04) is small, corrosion resistance, wear resistance, can work in the temperature range of -80~+200 degrees Celsius.
