Hydraulic ram BOP is the important component of well drillig
control equipment. It has the features: rapid open, labor-saving
operation, easy maintenance, use for safe and so on.
Ram BOP is mainly composed of housing, side gate, hydro-cylinder,
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 structures, the product has the following
1- The combined type hinge seat makes it's convenient to maintain
and disassemble theproduct.
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
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.
7- The two-way seal of piston rod can prevent the inter-leakage
between well fluid and hydraulic oil. And installation and
dismantling of packing set is convenient.
