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.

c. 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.

d. 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. 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 lubricating system the power end uses the combined lubricating system of forced lubrication and splash lubrication. There are two kind of forced lubrication system :one is inside mounting gear oil pump which is driven by the big gear, another is the outside mounting electric gear oil pump, when using the outside pump ,it is necessary that the inside mounting gear oil pump is dismounted.

3.2 Fluid End Features

The fluid end consists of three interchangeable suction cylinder and discharge cylinder,

the suction valve is mounted in the suction cylinder, the discharge valve is fixed in the

discharge cylinder, the suction and discharge valve are installed and dismounted through

the valve cover bore. The suction cylinder and the discharge cylinder are connected by

the bolts, suction cylinder is seated on the suction pipe, three discharge cylinder are

respectively connected to the frame through the bolt. The discharge manifold is installed

in front of the discharge cylinder, the discharge block assy. on which the discharge filter

and pressure gauge, discharge pulsation dampener are mounted, is mounted at one end of

the discharge manifold, the shear relief valve is assembled on the other end of the


discharge block assy.. The liner and the piston are installed at the back side of the

discharge cylinder, and insert into the frame bore. Suction pipe is positioned under the

suction pipe. There are suction inlet at the two sides and in front of the suction pipe,

which can be connected to the suction pipeline, the three suction flanges adopt the 12″

ASAB16.5-150PSI steel. Suction dampener is installed at the opposite side of discharge

dampener which is mounted at one end of the suction pipe. The liner and piston are

installed outside of the discharge cylinder.

a.Cylinders

Discharge cylinders and suction cylinders are made of forged alloy steel, three

discharge cylinders and suction cylinders of each pump are interchangeable L type

cylinder design make the repair and changing of valve convenience. At customers

request, the cylinder surface may be nickel plated to improve the abrasion resistance. The

taper ratio of the valve pots on the hydraulic cylinder is 1: 6, and the valve cup has a

shoulder, which is suitable for working under the high pressure. The cylinders are made

of the forged alloy steel, F-1600HL mud pump uses API 7# and API 7H valve pots. Their

size conforms to the API Spec 7k and china relevant standard.

Discharge pulsation dampener, shear relief valve connection pipe and shear relief valve

and discharge block are furnished at the two side outlet of the discharge manifold. and F-

1600HL pump suction inlet is furnished with Φ305 flange.

Valve Assembly The suction valve and the discharge valve for F-1600HL mud pumps are

interchangeable.

b. Liners,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. 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 liner chamber in the front of the frame, and fixed with liner

thread ring, liner lock ,bolt and wear plate when installing. The inner diameter of the

liners has ten grades, one each grade conform to the API 7k, but the outer diameter of the

liners are generally same.

Piston and Piston Rod conforms to the Norm of API 7k , piston consists of piston core,

rubber plate , pressing plate, block spring , piston is matched with the piston rod through


the cylindrical face and sealed by seal ring, and piston is firmly tightened by locking nut

1-1/2″－8UN-3B which has the looseness resistance ring which not only can prevent

the nut from loosing, but also can play the role of sealing. After this nut has been

tightened, the piston rod can not be worn, and it is through a separate oil tank, water is

supplied by centrifugal spraying pump and lubricated and cooled by water with anti-

rusting agent.

Piston rod and crosshead extension rod are firmly tightened by collar clamp, their fittings

are small clearance bore, which can guarantee the their alignment and be also quickly

check and repaired.

c. Valve cover

The cylinder and the valve cover are connected by buttress thread; the valve cover

presses firmly on the valve cover seal.

d. Valve assy.

The suction valve and discharge valve are interchangeable.

e. Discharge manifold and discharge block flange

Discharge manifold and discharge block flange on the hydraulic end adopt 51/8″API-

7500PSI 6BX flange, and the sealing ring in this place adopts API sealing with Size

BX169.

f. Discharge pulsation dampener

Discharge pulsation dampener adopts spheric pre-charged one with the maximum

working pressure of 7500psi (51.7MPa)and volume of 75 litre (20 gallon), which is

installed on the discharge block and is composed of the shell, bladder, gland cover,

pressure gauge cage ,and has made the pump discharge more smoothly and stably.

g. Shear relief valve

The shear relief valve is installed on the discharge manifold for the purpose of protecting

the pump from excessively high pressure overloads.

h. 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.

The durable fixed spray pipe is used. The spray pipe is mounted on the liner end cover


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.

i. 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 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.

j. 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.
