Рам ПБ

Ram BOP is mainly composed of housing, side gate, hydrocylinder,cylinder cap, piston, piston rod, lock shaft, sealing parts, ram, etc. Oil well’s sealing or opening is achieved by moving ram, which is driven by piston rod and piston with hydraulic force. Compared with products of other struc tures , the produc t has the following characteristics: 1. The combined type hinge seat makes it’s convenient to maintain and disassemble the product. 2. In order to guarantee the reliable sealing, the shaft sealing parts are locked by stainless plates and screws. 3. Seal ring of the side gate adopts reinforced rubber material to guarantee side gate’s lifespan and its reliable seal. 4. The ram structure makes it’s easy to change the rubber core and fore rubber core on the ram. The floating top rubber core can increase the seal reliability. A leading block, which mounted on the foreside of ram assembly, makes the drilling tools have automatic centering function. 5. The horizontal secondary seal equipment of side gate piston rod and sealing leakage hole not only guarantee the exchange ability of the side gate, but make leakage checking and secondary sealing operation be convenient. 6. Guide rib in the ram chamber of the housing can limit the moving direction of the ram.
