The impactor basic structure in general by the gas distribution mechanism, both inside and outside the cylinder, piston components.

By changing the inlet and exhaust direction, can realize the piston in the cylinder continuously reciprocating movement, thereby also can constantly repeated impact drill bit, this is the most simple impactor principle and process.

Speed depends mainly and the impacter frequency, size and physical mechanical properties of rock drilling. The general speed of 20 revolutions per minute or so to choose good, speed is too high will cause bit severely wear and drilling efficiency is reduced, because of DTH hammer in Qigong is impacting breaking rock, rotary speed to change bit alloy shock rock breaking position, to avoid duplication of broken, therefore, reasonable speed should be guaranteed in the best impact spacing range.

The United States of America well learn Kang burr believed in hard rocks two impact between optimal angle is 11 DEG, which advocates the drill spindle speed in the range of 18 ~ 30R / min. There is also the domestic scholars think, the drilling rate selection in 20 ~ 50 rpm it is more reasonable to use low speed, hard rock, soft rock selection for higher speed.

沖擊器的基本結(jié)構(gòu)一般由配氣機構(gòu)、內(nèi)外缸、活塞幾部分組成。

 通過不斷改變進排氣方向**可實現(xiàn)活塞在氣缸內(nèi)的不斷往復(fù)運動，從而也能不斷反復(fù)沖擊鉆頭，這**是沖擊器工作的**原理和過程。

 轉(zhuǎn)速的高低主要和沖擊器的沖擊頻率，規(guī)格大小以及鉆巖的物理機械性質(zhì)有關(guān)。一般轉(zhuǎn)速選用每分鐘20轉(zhuǎn)左右為好，轉(zhuǎn)速過高會造成鉆頭的嚴(yán)懲磨損和鉆進效率的降低，由于氣功潛孔錘進是以沖擊碎巖的，回轉(zhuǎn)速度為改變鉆頭合金的沖擊破巖位置，避免重復(fù)破碎，因此，合理的轉(zhuǎn)速應(yīng)保證在**優(yōu)的沖擊間隔范圍之內(nèi)。
美國水井學(xué)會康伯爾認(rèn)為在硬巖中兩次沖擊之間的**優(yōu)轉(zhuǎn)角為11°，因而主張鉆機立軸轉(zhuǎn)速在18～30r/min。也有國內(nèi)學(xué)者認(rèn)為，鉆速選擇在20～50轉(zhuǎn)/分是比較合理的，對于硬巖層選用低轉(zhuǎn)速，對于軟巖層選用較高轉(zhuǎn)速。
