2. Structure Features 2.1 Power End Features
a. The Frame The frame is made of welded steel plate and stress relief treated to
obtain the good rigidity and high strength. The place where the crankshaft bearing is
fitted is strengthened by using ribbed plates. The frame is furnished with the necessary oil
basin and oil way system for cooling and lubricating purpose.
b. The Pinion Shaft The pinion shaft is made of forged alloy steel on which a
herringbone gear with the medium-hard tooth surface is machined. For easy maintenance,
the single row radial long cylindrical roller bearing with inner ring (without sides) is
used. The both ends of the pinion shaft extend out, so that the sheave or the sprocket can
be mounted on either end.
c. The Crankshaft The crankshaft is made of cast alloy steel and furnished with
herringbone gear, connecting rod and bearing. The tooth form of the big-geared ring is
herringbone gear. The gear bore and the crankshaft surfaces are interference fitted and
they are both fastened with bolts and lock nuts. The big end of the connecting rod is
mounted on three eccentric straps of the crankshaft through single row short cylindrical
roller bearings and the small end on the crosshead pin through double row long
cylindrical roller bearing. Double row radial spherical roller bearings are mounted at both
ends of the crankshaft.
d. The Crosshead And Crosshead Guide The crosshead and crosshead guide are
made of homebred meehanite cast iron featured by good abrasion resistance and long
service life. Upper and lower guides are used for mud pump, so that the concentricity can
be adjusted by adding shims beneath the lower guide. The connection between the
crosshead and the extension rod is made by using bolted flange. The rigid connection
ensures the concentricity of the crosshead and the extension rod. The coupling is used for
connecting the extension rod to the piston rod. The lightweight coupling enables the
extension rod and the piston rod to connect to each other easily and reliably.
e. The Extension Rod Packing. The extension rod packing is duplex seal structure
to provide the good seal result.
f. The Power End. The power end uses the combined lubricating system of forced
lubrication and splash lubrication.

2.2 Fluid End Features
a. Cylinders Cylinders are made of forged alloy steel, three cylinders of each pump
are interchangeable. Valve-over-valve (through type cylinder) design reduces the
cylinder volume and promotes the volumetric efficiency. At customers’request,
the cylinder surface may be nickel plated to improve the abrasion resistance.
b. Discharge pulsation dampener, shear relief valve and discharge block are
furnished at the outlet. F-800 pump suction inlet with 10" flange and F-1000
pump suction inlet with 12" flange. c. Valve Assembly The suction valve and the discharge valve for F-800 and F-1000
mud pumps are interchangeable. F-800 and F-1000 mud pump uses API 6# valve
pots.
d. Liners Bi-metal liners are used. The sleeve is made of wear-resistant cast iron, the
surface hardness is HRC60~65. Therefore, liners feature wear resistance,
corrosion resistance and high surface finish. Liners are put in from the cylinder
cover bore in the front of the cylinder and fixed with liner cage, cylinder cover
plug and cylinder cover when installing.
e. Pistons And Piston Rods They are slide fitted, sealed with rubber seal ring and
finally fastened with lock nuts to prevent the piston from looseness and to play a
role in sealing.
Cylinders, liners, pistons, valves, valve seats, valve springs, seal rings, valve
pot covers and cylinder covers at the fluid end of F-800 and F-1000 mud pumps
are all interchangeable.
f. Spraying System The spraying system consists mainly of spray pump, cooling
water box, and spray pipe, the function is to cool and rinse liners and pistons to
promote their service life.
The centrifugal spray pump can be driven by a sheave mounted on the input
shaft extension end or a separate motor and cooled and lubricated by water.
Follow-up pray pipe is used. The spray pipe is mounted on the piston rod clamp
and the frame. Nozzle is face to the piston end so that the lubricating-cooling fluid
can rinse the contact surface between the piston and liner all the time.
g. Lubricating System The power end uses the combined lubricating system of
forced lubrication and splash lubrication. The pressure oil is conveyed through
lubricating pipeline, crosshead, extension rod, crosshead guide and all bearings by
Charles Rig Supplies, Inc.
a gear oil pump within the oil box to realize the forced lubrication. The working
condition of the gear oil pump may be understood from the pressure gauge behind
the frame.
h. Charging System To prevent the air lock occurring for low pump inlet pressure,
every mud pump should be furnished with a complete charging system. It consists
of charging pump,pump base, butterfly valve and corresponding manifold.
Mounted on the suction manifold of the mud pump, the charging pump is driven
by the special purpose motor or the input shaft of the mud pump through V-belts
to reduce the power consumption.
