FH系列反夯锤
产品概念

产品介绍 FH系列反夯锤 用途 :振动起拨套管、振动起拨钻杆、冲击裂管等。 作用原理 :对起拔套管、起拔钻杆提供振动力和向钻杆方向的冲击力,从而使套管、钻杆、管道等产生松动,实现用更小的力而起拔出来。对管道原位置换的裂管头提供冲击力,能将水泥管的钢筋击断,能将波纹管的钢带击断,从而提高换管成功率。 连接 :前端通过减振装置与钻杆连接,从钻杆内送气,并由钻杆提供拉力。减振装置可有效地减小冲击力通过钻杆传递到钻机动力头,从而保护钻机不受冲击而损坏。后端与套管、钻杆或拉扩头相连接,并将冲击力传递到其上。 Use

FH系列反夯锤
用途:振动起拨套管、振动起拨钻杆、冲击裂管等。
作用原理:对起拔套管、起拔钻杆提供振动力和向钻杆方向的冲击力,从而使套管、钻杆、管道等产生松动,实现用更小的力而起拔出来。对管道原位置换的裂管头提供冲击力,能将水泥管的钢筋击断,能将波纹管的钢带击断,从而提高换管成功率。
连接:前端通过减振装置与钻杆连接,从钻杆内送气,并由钻杆提供拉力。减振装置可有效地减小冲击力通过钻杆传递到钻机动力头,从而保护钻机不受冲击而损坏。后端与套管、钻杆或拉扩头相连接,并将冲击力传递到其上。

Used for: Vibration pull casing, vibration pull drill pipe, impact crack pipe, etc.

Principle of action: It provides vibration force and impact force to the direction of drill pipe to loosen the casing, drill pipe or a other pipe, so as to pull out with less force. Provide impact force to the crack pipe head of the in-situ replacement of the pipe, can break the steel bar of the cement pipe, can break the steel belt of the bellows pipe, so as to improve the success rate of tube replacement.

Connection: The front end is connected to the drill pipe through a damping device, and the air is supplied from the drill pipe, and the drill pipe provides tension. The damping device can effectively reduce the impact force transmitted through the drill pipe to the power head of the drill rig, thus protecting the drill rig from impact and damage. The rear end is connected to the casing, drill pipe or extender head, and the impact force is transmitted to it.
