Pneumatic wrench principle

Taizhou fengleiyi machinery&electronic co.,ltd. is a professional manufacturer of pneumatic tools for design, development, production, sales and service. It is located in the middle of China Gold Coastline. Water, land and air transportation is convenient, network, communication and information is developed. Of the coastal business in Zhejiang coastal city - Taizhou here is an important birthplace of China's stock cooperative economy. The company was founded in 2010, the predecessor of Taizhou Yuyu Pneumatic Tools Co., Ltd. Existing staff of more than 300 people, more than 30 professional senior technical staff.

   At present, the main production of industrial-grade assembly of pneumatic tools, is committed to the production industry, cutting-edge products, including professional-level specifications of the gun wind approved, wind guns, especially oil-type, hydraulic pulse pneumatic tools is the industry's cutting-edge products. The company's products are mainly used for automobile, motorcycle, electric car, bicycle assembly and maintenance of motor engines, generators, agricultural machinery, air compressors, small machinery and other products for the assembly of the world's automotive, pipe, ship and other industrial manufacturing and automotive After-sales service market widely used, and exported to Europe and the United States and the Middle East and other countries.

   Pneumatic torque wrench is a high-pressure air pump as the power source of the torque wrench. Is driven by one or two powerful pneumatic motors with a torque multiplier with three or more turnaround gears. By adjusting the gas pressure to control the torque size, to allow specific torque requirements to be set, each tool is equipped with a dedicated air pressure first to the torque of the control chart and calibration report. And for further application, pneumatic torque wrench can also be used with torque sensors, the output torque is more accurate. After obtaining the required torque, use a suitable circuit system to manually or automatically turn off the air supply. The following are the same as the "

   Pneumatic torque wrench is a hand-held rotary pneumatic tools, you can accurately set the torque for the nut and bolt locking or disassembly work; control part of the regulator and power management system through the realization of the mechanical part of the planetary gear reduction mechanism [1] The operation of the pneumatic torque wrench is quiet - less than 85dB (A), absolutely no impact, reducing the damage to the tool, sleeve and lock, these two factors can make the use of tools to operate Comfortable, reduce fatigue, improve safety, torque up to 300,000Nm.

   Pneumatic torque wrenches provide precise torque control - ± 5% repeatability, with sensor + solenoid valve switch, repeatability up to ± 2%. Pneumatic torque wrench with its small size, light weight, the unit weight output power, can achieve high torque output, small reaction force, environmental pollution, low cost advantages, widely used in aerospace, mining, petrochemical, railway, Heavy vehicle assembly and maintenance, heavy equipment handling and many other areas, especially in the production line assembly has been widely used, especially the need for high torque occasions. Category: Pneumatic wrenches are generally divided into two categories, one is conventional is also a very ordinary impact wrench, one is a pulse pneumatic wrench, the difference between the two is that the former can not be fixed torque, while the latter can. Pneumatic torque wrench belongs to the latter.
