W-440 Oil Rig Mud Pump Details

Frame
The machine 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 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 the 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 ordtoase the corrosion resistance. The three hydraulic cylinders of a
pump are interchangeable.
Liner
W440/446(500HP) pumps have 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
It adopts a power-driven spraying system
