The use of cylinder requirements

) 'Cylinder' general working conditions is: the surrounding environment and medium temperature, pressure of work. ~。 Mpa（ Gage pressure) 。 Beyond this range, the use of special sealing materials should be considered and very dry air. ) Before installation should be in. Under free times the working pressure, there is no leakage. ) In the whole work of load change is big, have enough output allowance cylinder should be used. ) In order to avoid impact damage parts. ) Pay attention to the reasonable lubrication, in addition to the cylinder lubrication system should be set up correctly and adjust the oil mist detector, otherwise will seriously affect the motion performance of the cylinder can't even work. ) Cylinder must pay attention to when using the piston rod strength problem. Due to the threads of the piston rod head impact damage, the piston rod is thrust load under most situations, thin rod lever stability and must be considered when horizontal cylinder piston rod out caused by weight of the piston rod head drooping. Also note when installation stress direction, the piston rod is not allowed to bear radial load. ) The piston rod head, in the big inertia load movement stops, often accompanied by shock, due to the impact and easy to cause damage to the piston rod head. When use, therefore, should check the load inertia force, the setting load stop block device and buffer device, and eliminate unreasonable force acting on the piston rod under. Second, the key points of the selection of the cylinder) According to the load status of cylinder and the load motion load and load factor F is determined, then according to the principle of using air pressure is the pressure should be less than %, according to the air pressure determined using pressure P. The single-acting cylinder according to the rod diameter and diameter ratio. , double-acting cylinder rod diameter and diameter ratio. ~。 Primary, and according to the formula can be obtained by the cylinder diameter D, the value of D for standardization. Such as D size is too big, can use mechanical force. ) Cylinder and transmission mechanism based on the actual running distance to primary cylinder stroke, for ease of installation and debugging, to calculate the distance to intensify ~ mm advisable, but not too long, so as not to increase the gas consumption. ) According to the purpose and the installation location to determine the variety of cylinder and installation form. Refer to relevant manual or product samples. ) Piston ( Or cylinder) Mainly depends on the movement speed of cylinder inlet and outlet and the tube diameter, are chosen based on cylinder into the vent connection thread sizes. In order to obtain a slow and steady movement can adopt gas-liquid damping cylinder. Normal movement speed of the cylinder. ~ m/s or so, should choose buffer cylinder of high-speed movement of the cylinder or buffer are added into the loop.
