Power Swivel

DSL135 power swivel (hereinafter referred to as “this Product”), of which central pipe rotates under driving force of hydraulic variable motor through gear reduction system, is featured by compact structure and designed weight of 1,200 kg, making it applicable to drilling or work-over derricks. 

This Product can provide smooth and shock-free torque, have the maximum static load of 1,350kN at zero speed. 

This Product is applicable to assembly/disassembly of long and single drilling rods without using spinning chain, pipe wrench and Kelly spinner and, by reducing the startup/shutdown times of drilling rig, this Product can help improve the efficiency of drilling rig and reduce the wear of pump, winch and other drilling equipment. 

This Product is configured with closed loop hydraulic system, of which remote hydraulic control operating device is equipped with hydraulic control proportional handle in order to adjust the flow and direction of hydraulic oil. This Product’s central pipe can realize infinitely speed change of revolving speed. 

This Product also covers the functions as common swivels. While central pipe enters revolving or static state, drilling fluid will enter the drilling rod through goose neck, wash pipe and central pipe for circulating. 

This Product is composed of two parts, i.e. YSL135 hydraulic swivel and DKYC320/34.5Y hydraulic power control device, all of which are mounted on the entire skid body, sturdy and compact. 

This Product is featured as follows: 

1) Provide smooth and shock-free torque and reduce damage on drilling string; 

2) Fit many well drilling and work-over derricks; 

3) Allow use of longer drilling sting lengths; 

4) Torque limit can be set;

5) Substitute traditional rotary swivel; 

6) Wholly mounted on skid body for easy transport. 

This Product is applicable to: 

1) Ideally suited for use in fishing and workover operations, such as cutting of internal/external casing, tubing or drill pipe; drilling out plugs, packers, or cements; milling operations; or scraping casing, whenever shock-free, controlled torque is essential to eliminating the potential danger of twist-offs or damage to cutting tools. 

2) Drilling operation: with compact and light-weight structure, this Product can be used in minor and medium-sized drilling operation, including drilling of oil well, gas well, as well as drilling of water well, pier piling and laying of foundation. 

3) Drilling sampling: this Product can also be used for drilling sampling. With reasonable and stable torque, this Product can well protect the coring tool or tubular columns against damage, and support drilling of rock core at any length.
