Sell Ram type BOP

详情

Ram type BOP is simple and compact and is suited for land and platform applications. The ram in the BOP is pressure energized. The well pressure acts on the ram to increase the sealing force and maintain the seal even with loss of the closing pressure. Ram type BOP can be supplied with the hydraulic locking devices to lock ram hydraulically and hold the ram mechanically closed even when actuating pressure is released. The operating system is interlocked using sequence caps to ensure that the taper lock is retracted before pressure is applied to open the BOP. Ram type BOPs bonnet are opened and closed by hydraulic pressure and the ram change is quick and easy. All operating parts, as well as, the rams and seals can be replaced on site, thus providing a completely reconditioned preventer. Blowout Preventer RING BOP In case of blowout and well-sealing is needed.high pressure oil coming from control system enters the bottom closing chamber from bottom inlet to push piston moving xxxxx movement of piston forces tubber core to move upward along the sphere surface, then supporting ribs get closer to push the internal rubber towards the wellhead center to fulfill the function of sealing drill equipment or the wellhead. When unlocking the seal is needed,hydraulic oil pushes the piston moving downward and the rubber core will reset to its original under its elastic force. Structure Characteristics xxxxx connection between top cap and housing ,top and bottom ends adopt flanges and bolts. 2.Semisphere rubber core has many advantages,such as not easy folding back, big volume of rubber storage.Under the well pressure,the piston pushes the rubber core upward to form a funnel xxxxx funnel effect of rubber core increaseas its sealing performance and life span. xxxxx of the sealing structure The BOP has three important sealing positions:piston external surface seal,piston internal surface seal and mud block
