What are the working principles and structures 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.4, maintenance costs:Less supplies, as long as pay attention to regular filling, special pneumatic maintenance, refueling, generally in a year without changing parts.
1 rpm: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.2 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.)
Pneumatic screwdrivers operate with compressed air as power. Some are equipped with a device for regulating and limiting torque, which is called fully automatic adjustable torque type. For short (automatic pneumatic screwdriver), some do not have the above adjustment device, but only use the switch knob to adjust the amount of air intake to control the speed or torque. Semi automatic, non adjustable torque type. Short acting (semi-automatic pneumatic screwdriver). Mainly used in various assembly operations. A pneumatic motor, Chuida device or deceleration device components. Because of its fast speed, high efficiency, low temperature rise, has become the indispensable tool for assembling industry. Product sources are divided into two channels: domestic and imported. The form of semi automatic Chuida, automatic torque control. Operation start mode has lower press, hand press type, respectively.
