(excluding 90” Gooseneck) Pull Force High (working) : 100,000 Lbs. - Snub Force : 40,000 Lbs. - Max Speed : up to 200 ft/min. - Speed @ 30,000 lbs Pull : up to 190 ft/min (+/-5%) Chain Type : Varia-Block III Heavy - Gooseneck (Flared) : Two (2) Piece, 90” Hydraulic Folding Motors : Two (2) Axial piston, variable displacement 3.0 TOP DRIVE/BRAKE SYSTEM - The top drive/static brake assembly consists of two (2) variable displacement, axial piston hydraulic motors, double reduction planetary gear reducers, and spring applied, pressure released, multi-disc brakes. These assemblies are flange mounted to the injector body and drive the carburized drive sprockets and timing gears. - The drive motors are protected by high-pressure filters with reverse flow check valves. Each filter will have a 10 micron, stainless steel, and cleanable element. - Hydraulic load holding counterbalance valves are installed at the motor ports to hold the tubing load (in and out hole) when the brakes are released. 4.0 DRIVE CHAIN DESCRIPTION - Steel plate body construction with full access side openings to enable easy removal of the drive chain and tubing blocks. - The drive chains and injector blocks may be fitted for tubing sizes of 1” OD through 2- 7/8” when fitted with the Varia-Block III chains. - The traction chains are designed to transmit a force of not less than 100,000 Lbs. in the out-hole and 40,000 Lbs. in the in-hole directions from a stalled position. Slippage of the tubing relative to the gripper blocks will not occur at pulling force of 100,000 Lbs. with the surface of the tubing and blocks in a diesel wet condition. The force exerted by the chains on the tubing will not mark the surface of the tubing. - The two (2) drive chains are of the roller chain type with connecting links to allow for replacement of the drive chains and injector blocks while the tubing remains in the injector. - Separate connecting shafts connect the tubing blocks to each of the drive chains instead of the more common single through shaft, which causes adverse stressing of the tubing blocks in the case of misalignment of the drive chains and coiled tubing. - Clearance between the tubing blocks when fully retracted allows for the passage of the various tools that are normally used in coiled tubing strings. The feature also allows easier tubing stab-in into the injector. - The tubing blocks are the new Varia-Block III design. The new design incorporates a longer contact area per block to maintain contact with two (2) roller bearings at all times, and as many as three (3). The new design reduces wear, prolongs life, and should significantly reduce overall maintenance costs of the injector head and some of its parts 5.0 CHAIN TRACTION SYSTEM - Chain traction is achieved by the use of a single skate/roller bearing assembly that applies pressure to the backsides of both drive chains. These roller assemblies are each compressed by single hydraulic cylinders. The 10 (10) hydraulic cylinders are plumbed in two (2) sets of five (5) hydraulic cylinders. If a failure in the hydraulic cylinders or tubing occurs, one (1) set can be isolated from the other and traction maintained on the tubing. Each hydraulic circuit incorporates an accumulator to prevent variations in tubing diameter to vary the hydraulic pressure. Each control circuit is protected by a velocity fuse to prevent loss of control due to hose failure. The two (2) sets of five (5) hydraulic cylinders have one (1) pressure control at the panel since the 10 (10) hydraulic cylinders operate at the same hydraulic pressure. This tubing traction system drastically reduces the tubing damage that is normally associated with excessive roller skate assembly hydraulic pressure. - The roller skate assemblies use large 2-3/8” diameter roller bearings. The use of these large roller bearings with the new chain and block design ensures that two (2) rollers are in contact with each tubing block prior to transition from one (1) bock to the next at all times. This feature prevents pivoting and clattering of the tubing blocks as they pass over the drive chain sprockets and reduces the stress on the tubing caused by the gripping of the tubing blocks on the tubing. The tubing roller bearings are equipped with full lip - seals for greater grease capacity and sealing capability and use large rollers with increased load ratings. 6.0 CHAIN TENSIONING SYSTEM - Chain tensioning is achieved by a direct vertical movement of the bottom drive chain idler sprockets by two (2) pairs of hydraulic cylinders powered by a single hydraulic circuit with back-up accumulator for ease of operation. This feature gives a greater range of drive chain tensioning without reducing the drive chain contact on the drive chain drive and idler sprockets and thus increases the life of the drive chains. 7.0 TUBING GUIDE GOOSENECK - The Heavy-Duty Tubing Guide Gooseneck is a 90” radius with steel roller straightener lower section and steel rollers on upper section. All bearings with grease zerts. - Gooseneck will fold downward for storage by means of a hydraulic cylinder. The cylinder will also act as the stiffener for the tail section of the gooseneck. - Heavy-duty pins and hinges on gooseneck. 8.0 GENERAL - The injector pivots on one (1) side of the injector frame base, a load cell sensor is installed on the other side of the injector. The pivot bearings are lubricated. - The injector is installed in an outer lift frame with steel base, guards, and a four (4) point lifting system, access ladders, and decking of the top of the protection frame. - The injector is equipped with a bottom flange connection and adapter for use with a customer furnished 3.06 15M TOT Over/Under stripper/packer assembly. - Compression cylinder piping is done in all stainless steel tubing to lesson the likelihood of a control line rupture on location. - Velocity fuses are provided in the control circuit lines to prevent loss of control in the event of line failure. Fuse reset valves are provided for each circuit. - All hydraulic connections on the injector are piped to a quick disconnect coupling panel, using bulkhead fittings installed at the bottom front side of the injector. All hoses will be supported by chain and hook arrangement so that hose connections do not carry a heavy load. - Drain in bottom of drain pan, 1-1/2 NPT. - Dual Hydraulic/Electronic load cell attachments - Safety belt hooks at top of injector, recessed below plate. - Chain attachment padeyes on top four (4) corners of frame, directed inward. Automatic brake release with injector motor pressure.
