QGB cylinder matters needing attention and main points of choice

Application note QGB QGB cylinder cylinder use clean and dry compressed air. For the oil cylinder, the need to provide compressed air filtered, lubrication, and maintain long-term lubrication of compressed air, lubricating oil should be used for oil ( Turbine oil) And shall not use the oil, lake seed oil, etc. , to avoid damage to NBR rubber parts. Both adaptable to not give oil cylinder, filtering, no oil compressed air, also can adapt to long-term lubrication of compressed air ( As to the oil and gas cylinder to apply) , but should not be oil sometimes, and sometimes no oil supply, because no to oil and gas cylinder piston rod piston friction pair with self-lubricating materials, cylinder after a certain time in operation, has been formed in the contact surface of the moving parts of a layer of self-lubricating film, sometimes the oil supply will hedge has formed since the lubricating film layer, sometimes less oil will make its friction pair again. QGB cylinder screen refers to when the dust particle diameter of the filter material on the space between the fibers or filter material of the gap between dust big, dust in air flow through the resistance to stay. The effect of inertia force refers to the circulation of air filter cloth can around the fiber, and the larger dust particles under the action of inertial force, still can be carried out in accordance with the original direction of movement, and liao collided and caught. Thermal motion effect refers to the small dust with airflow movement, the light body very close to the air line, can bypass fiber. QGB choice of cylinder QGB cylinder load state and load motion state of load and load factor F, 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 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. QGB cylinder and transmission mechanism of the actual 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. Purpose and installation location to determine the varieties and installation form of cylinder. 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.
