W-447 Oil Rig Mud Pump Details
Frame
The Mud Pump Oil Rig frames are welded with steel plates and
processed to
eliminate stress after welding, therefore. There are reinforced
plates at the seats
of the crankshaft and main bearing so that they have good stiffness
and strength.
Crankshaft
The crankshaft of the Mud Pump Oil Rig is in a balanced structure
with welded forged parts. It
is light and can operate smoothly without vibration. Both sides of
the
crankshaft are equipped with double-aligning spherical roller
bearings to ensure stability in operation and to improve its
bearing capacity.
Pinion Shaft
It is made of forge alloy steel, herringbone gears (integral) are
machined
on the shaft and it adopts a medium hard tooth surface. There is a
shaft
extension at both ends, where bell pulleys or chain wheels may be
installed.
Crosshead
The crosshead is made of a one-piece cast with nodular cast iron,
so the
crosshead has good abrasion resistance. The structure of top and
bottom
guidance is adopted for crossheads to regulate the concentricity by
adding a gasket at the bottom guidance. The extension rods are
connected
to the crossheads by flange bolts with pin holes, to ensure the
concentricity of the crosshead and the extension rods. The packing
adopts
a double-layer sealing structure, which realizes good seal
performance.
Fluid Cylinder
The cylinder is made of forge alloy steel and adopts a straight-way
structure. The hydraulic cylinder has a small size and higher
volume
efficiency. The cylinder surface is processed by chemical plating
in tortoise the corrosion resistance. The three hydraulic cylinders
of a
pump are interchangeable.
Liner
W440/446(500HP) Mud Pump Oil Rig has the same liner O.D. The liners
are
mounted tightly on the end face of the hydraulic cylinder by using
squareness
capping and bolts. Sealing between the liner and the hydraulic
cylinder is
realized by rectangular rubber gaskets.
Lubrication System
The pump adopts forced lubrication. In the oil tank, there is a
gear oil
pump, which transmits pressure oil to crossheads guidance as well
as the
bearings, to realize forced lubrication and cooling.
Spraying System
Mud Pump Oil Rig adopts a power-driven spraying system
