شرح مانع الانفجار نوع كاميرون-CAMERON U II Blowout Preventer
The Cameron U II BOP takes all of the features of the U shindig preventer and adapts them for subsea use in the18-3/4-,10000 and,15000 psi WP sizes.Like all other Cameron preventers, the preventer rams in the U II BOP are pressure amped . Wellbore pressure acts on the rams to increase the sealing force and maintain the seal in case of hydraulic pressure loss.
Seal integrity is actually bettered by increased well drag pressure.
Other features of the U II BOP include
- Internally ported hydraulic superstud attaching system ensures that superstud lading is constantly accurate and indeed.
- Bonnet seal carrier is available to exclude the need for high makeup necklace on bonnet superstuds and nuts.
- Hydraulically operated locking mechanisms, wedgelocks, lock the ram hydraulically and hold the rams mechanically closed indeed when actuating pressure is released. The operating system can be interlocked using sequence caps to insure that the wedgelock is repudiated before pressure is applied to open the BOP
- A pressure balance chamber is used with the wedgelocks to exclude the possibility of the wedgelock getting uncorked due to hydrostatic pressure.
- Other features include hydraulically opening bonnets, forged body and a wide selection of rams to meet all operations
