静扭式风扳机不同于冲击式风扳机。它的特点是在进气压力不变的情况下,可以得到比较精确的拧紧扭矩,并且不受时间及被拧物的条件(硬性联结、弹性联结或软性联结)所影响。但在机壳上承受的反作用扭矩等于拧紧扭矩,因此扭矩较大的静扭式风扳机大都组合起来或者安装在一个固定装置上使用,而不像冲击式风板机那样机动灵便。 Static torsional wind trigger is different from the impact of the wind trigger. Its characteristic is that it can get more accurate tightening torque under the condition of the same inlet pressure, and it is not influenced by the time and the condition of the screwed object (rigid connection, elastic connection or soft connection). However, the reaction torque on the housing is equal to the tightening torque, so most of the torsion torque type of static and dynamic wind-driven trigger are combined or installed on a fixed device to use, rather than the impact of the wind machine as flexible.
