Performance characteristics of pneumatic screwdrivers
Energy consumption:The use of compressed air as power source as long as the air consumption of air pipeline is reasonable for each of about 0.28 square meters with about /min, relatively more energy saving and environmental protection.Maintenance cost:Less supplies, as long as pay attention to regular filling, special pneumatic maintenance, refueling, generally in a year without changing parts.Advantage：Mainly lies in the work speed, high safety, anti-static, low failure rate, long life, energy saving and environmental protection;Shortcoming:Compared to electric noise, the accuracy of torque error comparison of electric should be large, so the operation is not flexible to pipe.
Rotational speed:Speed is generally less than 500-8000r/min, because the motor is driven by high-pressure gas, the operation of high-pressure air will take away the friction of parts of the heat generated, so long hours of high-frequency operation will not be hot.Torque accuracy:Mechanical brake, and changes in pressure will affect the stability of the torque of the screwdriver, so the error is greater, and the repeatability is about 5%-3%. (if the air conditioner is installed, it will be better.)
