鉆桿接頭的扣型：內(nèi)平式：主要用于外加厚鉆桿。其特點(diǎn)是鉆桿通體內(nèi)徑相同，鉆井液流動阻力小；但外徑較大，容易磨損。貫眼式：主要用于內(nèi)外加厚鉆桿。其特點(diǎn)是鉆桿有兩個內(nèi)徑，鉆井液流動阻力大于內(nèi)平式，但其外徑小于正規(guī)式。正規(guī)式：主要用于內(nèi)加厚鉆桿及鉆頭、打撈工具。其特點(diǎn)是接頭內(nèi)徑加厚處內(nèi)徑小于管體內(nèi)徑，鉆井液流動阻力大，吉林小型樹坑機(jī)，在三種扣型中相對流動阻力比較大，但外徑**小，強(qiáng)度較大，吉林小型樹坑機(jī)，吉林小型樹坑機(jī)。上述三種類型接頭均采用V型螺紋，但扣型、扣距、錐度及尺寸等都有很大的差別。

工作時，電動機(jī)使飛輪加速旋轉(zhuǎn)以儲蓄能量，同時通過螺桿、螺母推動滑塊向下運(yùn)動。當(dāng)滑塊接觸工件時，飛輪被迫減速至完全停止，儲存的旋轉(zhuǎn)動能轉(zhuǎn)變?yōu)闆_擊能，通過滑塊打擊工件，使之變形。打擊結(jié)束后，電動機(jī)使飛輪反轉(zhuǎn)，帶動滑塊上升，回到原始位置。螺旋壓力機(jī)的規(guī)格用公稱工作力來表示。更大規(guī)格的螺旋壓力機(jī)用液壓系統(tǒng)驅(qū)動飛輪，稱為液壓螺旋壓力機(jī),比較大規(guī)格的有125兆牛。后來又出現(xiàn)用電機(jī)直接驅(qū)動飛輪的電動螺旋壓力機(jī)，它的結(jié)構(gòu)緊湊，傳動環(huán)節(jié)少，由于換向頻繁，對控制電器要求較高，并需要特殊電機(jī)。
