特点/Characteristics:

1.钳头结构为开口型,进入和退出工作位置快捷方便,整体式钳头的强度和刚度好;

Opening type,convenient and prompt to enter and slide off the working position,with an integral tong head of great strength and rigidity;

2.主、背钳都采用三颚板夹紧机构,保证了对管柱的最小伤害。主钳前两颚板为摆动式,后颚板为滚子爬坡式,拆装极为方便,最佳的切径比设计,保证了夹紧可靠;背钳为液缸推动夹紧的三颚板结构,可以夹管柱本体,也可夹接箍,结构简单,夹紧可靠;

Three-jaw-plate clamping device is adopted in the master tong and back tongs, which can ensure minimum string damage. Front jaw of master tong is swing type,rear jaw is roller climbing type, convenient to assemble and disassemble,the best design of diameter ratio,ensure the reliable clamping, Three-jaw-plate structure is adopted in the master tong and back tongs,this structure is hydraulic cylinder pushing and clamping style,it can clamp the body of the tubular,and also can clamp the coupling,with simple structure and reliable clamping.

3.只需更换硬质合金涂层牙块(在管柱上留有低应力点状痕迹,无直条状牙痕,简称“无牙痕”牙块。推荐用于3Cr、9Cr、13Cr、22Cr、25Cr 油套管)或细齿牙块(在管柱上留有微小的直条状牙痕,简称“微牙痕”牙块)分别达到不同的微损伤效果;

Only needs to change the Hardware alloy coating die(low stress point-like mark left on the tubular column,no straight strip tooth mark,No tooth mark die for short.it is recommended to use on 3Cr、9Cr、13Cr、22Cr、25Cr tubing and casing or fine tooth die(tiny straight strip tooth mark left on the tubular column, Micro tooth mark die for short.)

4. 采用四档转速,调速范围广,额定扭矩大;

Four-gear rotation is adopted for large speed regulation range,and the rated torque is large;

5. 采用安全门联锁装置,安全门打开,钳头不能运转,安全可靠;

Safety door interlock device is adopted, when the safety door is open,the tong head will not revolve,it is safe and reliable.

6.主、背钳整体框架式结构,背钳浮动式联接,主、背钳可调距离大,减少上卸扣对管柱的损伤;

The overall frame structure is adopted in the master tong and back tong,floating connection of the backup tong,distance between the master tong and backup tong can be adjusted,damage can be reduced to the tubular column in make up and break out operation.

7.与双泵液压站配套使用,实现初始以20~25rpm 的转速上扣,到台肩扭矩后以1~6rpm 的转速紧扣;

To be used along with Double pump hydraulic power station,it can realize a rotate speed of 20 ~ 25rpm when make up in the beginning,then fastening at a speed of 1~6rpm after reaching the shouldering torque.

8.配套扭矩、转速测试系统和专用双泵液压站可精确控制上扣扭矩和转速,能适时显示、控制、储存、打印扭矩等参数;适用于FOX、VAM TOP、BGT1、3SB、NSCC、WSP 等扣型油套管上扣。

To be used along with Torque and rotational speed test system and Double pump hydraulic power station can precisely control the make up torque and rotation speed,it can display、control、storage、print torque parameters and etc.,and it can apply to the make up of FOX、VAM TOP、BGT1、3SB、NSCC、WSP type of tubing and casing.

注:此动力钳使用低应力牙块起下特殊扣油管时必须按照《无牙痕油管钳下管柱操作规程》作业。

Note:When low stress die of this power tong is used to the make up and break out of the special threads tubing, Downhole String Operation Instruction of Non-marking Tubing Tong must be kept when in operation.
