螺栓拉伸器一般由液壓泵、高壓軟管、壓力表和拉伸體組成。其中液壓泵為動力源，壓力表反映泵的輸出壓力，高壓軟管聯接液壓泵和拉伸體。拉伸體是實現螺栓拉伸的執行元件。主要由活塞缸、活塞、支承橋和拉伸螺母組成。
Bolt stretcher is generally composed of hydraulic pump, high pressure hose, pressure gauge and stretcher. The hydraulic pump is the power source, the pressure gauge reflects the output pressure of the pump, and the high-pressure hose connects the hydraulic pump and the stretching body. The drawing body is the executive component to realize the bolt stretching. It is mainly composed of piston cylinder, piston, supporting bridge and tension nut.
工作時，動力源輸出的高壓油經高壓軟管輸送至活塞缸3，在壓力作用下活塞缸中的活塞上移，帶動拉伸螺母向上移動。拉伸螺母與工作螺栓螺紋聯接，從而拉長工作螺栓，使螺栓伸長達到所要求的變形量，變形控制在彈性變形范圍之內，然后進行預緊或拆卸作業，最后通過液力或者機械回位的方式使工作螺栓回復原來的形狀，完成作業。
When working, the high-pressure oil output by the power source is sent to the piston cylinder 3 through the high-pressure hose. Under the pressure, the piston in the piston cylinder moves up and drives the pull nut to move up. The stretching nut is connected with the working bolt thread, so as to lengthen the working bolt, so that the bolt elongation reaches the required deformation, and the deformation is controlled within the elastic deformation range. Then the pre tightening or disassembly operation is carried out, and finally the working bolt is restored to its original shape by hydraulic or mechanical return to complete the operation.
