1. The rotary BOP is designed with double elastomeric seal for long lifespan and high pressure for both dynamic seal and static seal.
2. Dispensing with hydraulic control system, the petroleum equipment adopts oil pump and water pump for lubrication and cooling.
3. The swivel assembly and the elastomeric seal for the rotary BOP can be disassembled and assembled integrally for rapid installation and replacement of the petroleum blowout preventer.
4. The lubricating oil for the offshore rig is forced to lubricate the bearing of the rotation control device, ensuring good reliability and long lifespan of the bearings.
5. Convenient and reliable, the combination of the hydraulic cylinder and locking device makes for easy assembly and disassembly of the clamp for the rotary BOP.
