Discussion on the working principle and advantages of various types of tension device shortcomings When the tension device on the market's performance advantages to distinguish has the following kinds, ranging from high to low can be roughly divided into servo type tension device, electronic type tension device, magnetic damping tension device, mechanical tension device! The operation principle of the servo tension device: Through the angular displacement sensor tension arm angle is converted into electric pulse signal to drive the servo motor automatic operation, tension switch echo agile, stable output tension, almost all firmly, manufacturing high precision end product! Advantages: from the traditional forced wire feeding method is changed into automatic wire feeding method, tension very stable, minimum tension of up to 1g, and with tension stable system, can automatically complete the tension stable equilibrium. Disadvantages: by the motor characteristics influence, using proposition in the 6m/s line speed following.
