RAM BOP

Ram bop 4568

S - Shaped Ram BOP The design and manufacture of S-shaped Ram BOP is according to API Spec 16A standard. S-shaped Ram BOP can be equipped with rams of various sizes. Structure Features: ● Body and side door are made of alloy steel; ● Use seal rings assembly to improve sealing of side door; ● Use floating type ram. Front ram rubber is separated from top ram rubber, making it more reliable in sealing and easier to change; ● Use buried oil way inside body. Loading hinge is separated from hydraulic hinge; ● Compact hinge structure makes it easy to assemble and disassemble; ● Use arc-shaped body chamber with four round corners as transition section to reduce stress peak value whenever bearing the pressure; ● Ram cavity can be fitted with ram assembly of same type BOP made abroad; ● Flange grooves are stainless steel lined. U - Shaped Ram BOP U-Shaped Ram BOP is designed and manufactured according to API Spec 16A standard and GB/T20174 Drilling and production equipment-Drill-through equipment, and is equipped with rams of various sizes. With the best quality front ram rubber, top ram rubber and flange sealing stacks, U-shaped ram BOP can work during the extreme working condition including extremely high or low temperature and extreme chemical environment. Structure Features: ● The pressure-bearing components are forged, so it has better strength and impact toughness; ● Floating sealing is applied to the cylinder cover and the open/close of the cover is realized by hydraulic power, so it is quick and convenient for changing rams; ● The auxiliary oil cylinder affords a smaller volume with same function; ● The ram rubber has massive storage volume, and it adopts self-contained sealing; ● The standard configuration includes a manual locking device, which ensures the ram is closed tightly in case there is a hydraulic pressure loss; ● Both the manual and hydraulic locking device and the auxiliary oil cylinder can be installed flexibly into different positions according to customers’ requirements, and the installation positions can be changed easily.

ROTARY TABLE

Rotary table 042 2722

otarytable’s parts mainly include rotary device body, cast base, input shaft assembly, locking device, main bushing device, and upper cover, etc. The rotary table is a cast steel piece, drilling tool and casing string can pass it through the hole in its center. To rotate the drill string, there are 2 grooves on the upper rotary table, and the 2 pin on upper main bushing device are seated in these two grooves. The base of rotary table device is on the primary and secondary combination bearings, which is supported on the bottom base through the off circle of bearings. The upper section of off circle of combination bearings acts as the primary bearing, which bears all load from drill column and casing string. The lower section of off circle acts as the secondary bearing, which is mounted on lower drilling platform via lower base circle to support the jumping-up from shaft bottom. The rotary table rotates using a pair of bevel gear pair. The Big teeth circle is installed on rotary table.The small bevel gear is fitted on one side of shaft which is in turn supported on the two bearings seated in the bearing pedestals. A flange and double row sprocket are fitted on the other side, making up an input shaft assembly. A locking device which brake the rotary table to rotate towards the left and right is installed on the top of turntable. One of the left and right ratchet pawls is fed into one of the 28 slot positions of rotary table by the joystick when the rotary table is braked. Main bushing device consists of two sections, the upper section includes two outshots seated in the grooves of rotary table.The big and small gears are all made from alloy steel. The main bushing as a whole is steel casting.The turntable is lubricated fully, and sealed safely.
