(Summary description)Electric screwdrivers and pneumatic screwdrivers both play their respective roles in our work and are essential assembly tools in modern industrial production. They can improve factory efficiency and product quality, providing us with great help in our work. Of course, every beautiful thing also has some minor flaws, as the saying goes, nothing is without flaws. Electric screwdrivers and pneumatic screwdrivers are the same, each with its own advantages and disadvantages. We can compare them horizontally from the following aspects: 1. Speed: The speed of an electric screwdriver is generally around 1000-2000r/min. Due to the electric spark generated by the motor during operation, the screwdriver is prone to overheating when operated at high frequency for a long time. The speed of a pneumatic screwdriver is generally around 1000-2800r/min, as the motor is driven by high-pressure gas, prolonged high-frequency operation will not cause overheating. 2. Appearance: The casing of electric screwdrivers is mostly made of plastic material, which conforms to ergonomic principles and is lightweight, making it more suitable for long-term operation. The casing of pneumatic screwdrivers is mostly made of metal material, which has a slightly worse hand feel than electric ones, but the metal casing has better anti-static performance. 3. Energy consumption: The energy consumption of an electric screwdriver is 55W/H. Pneumatic screwdrivers use compressed gas as the driving source. As long as the air pipeline is properly arranged, the air consumption of each screwdriver is around 0.28 ㎡/min, which is relatively more energy-saving and environmentally friendly. 4. Torque accuracy: Electric screwdrivers use electronic braking, resulting in higher accuracy, with a general repeatability of less than 3%. Pneumatic screwdrivers use mechanical braking, and changes in air source pressure can affect the stability of the screwdriver's torque, so the error rate is generally around 5% -3%. If an air conditioner is installed, it will be better. 5. Maintenance costs: Electric tools need to replace carbon brushes between 3 to 6 months, and there are also many consumables such as power cords, carbon brushes, bearings, etc. that require high maintenance in the future. Pneumatic screwdrivers have fewer consumables, so as long as you pay attention to maintenance and refueling, you only need to replace the fan blades within a year. In summary, the advantages of electric screwdrivers mainly lie in their convenience, high torque stability, and low price; Disadvantages: high failure rate and easy overheating. The advantages of pneumatic screwdrivers mainly lie in their fast working speed, anti-static properties, low failure rate, long lifespan, and energy-saving and environmentally friendly features; Disadvantages: poor hand feel, torque accuracy needs to refer to the stability of air pressure, and the price per unit is relatively high. Overall, pneumatic screwdrivers are superior to electric screwdrivers, but currently there are many branded merchants in the market, and counterfeit and shoddy knockoffs are also common.
