Mud Pump is used to circ
Mud Pump is used to circulate drilling fluid while drilling, it is the heart part of drilling fluid circulation system, and it is composed of Power End and Fluid End.
Technical Performances and Structure Features
1.Power End: the frame is welding structure with steel plate, it has high strength, rigidity and light weight, It is stress-relieved after welding. The transmission gears are integral involute herringbone, with smooth running, high efficiency and long service life. The crankshaft is hollow one-piece casting. At the Power End, we adopt splash and forced lubrication.
2.Fluid End: compact structure is due to adopting straight pass through fluid cylinder. The suction and discharge flange conform to ANSI and API Spec.
3.Piston Rods and Intermediate Rods are jointed by collar couplers that allow quick installation/disassembly.
4.The piston and line bore are cooled and lubricated by independent spray pump system, has long service life.
5.The expendables are universal.
2. INSTALLATION OF NEW PUMP
Your F-series pumps has been completely assembled and test operated under pressure
before being shipped to the field. Unless otherwise instructed, the lubrication is
drained form the power end. Before putting the pump into service, the following
precautions and operations must be performed or checked.
In order to prevent personal injury during the performance of any maintenance or
inspection procedures, this equipment MUST BE SHUT DOWN AND NOT OPERATION,
and all safety devices on prime movers, drives, etc., MUST BE IN THE SAFE POSITION.
2.1 Setting The Pump
The skid under the pumps manufactured by our company is suitable for most any type
of installation . It should be noted , however, that the box type construction of the power
frame has high resistance to bending but relatively less resistance against twist. Therefore,
the support under the pump must be level and adequate to support the weight and
operating forces exerted by the pump.
2.2 Land Installations
In land installations, a mat of 76mmx 305mm boards laid side crosswise to the pump
skids for the entire length, or at a minimum, at the points indicated in Fig.2, is usually
sufficient. The boards should be a few feet wider than the width of the pump skid runners.
Wet or marshy locations may require a more stable foundation.
Fig. 22.3 Permanent Installations
On permanent installations such as barge, platform, structural base, or concrete slab,
where pump skids are bolted down, it is essential that the skids be properly shimmed to
prevent possibility of twisting or distorting the power frame. The pump skids must sit solid
on all shim points with bolts loose.
On barge installations, the pump skids are generally bolted down to T-beams running
parallel and in line with the pump skids. Install shims at points shown in Fig, 2 and 3 and
observe caution of proper shimming to prevent twist or distortion.
The shims on all installations should extend the full width of the skid beam flanges and
have a minimum length of 12″ (305mm).
On installations where the power unit or electric Motor is mounted integrally with the
pump skids, the preferred installation would be to set the pump package on the T-beam
skids and provide retention blocks rather than bolts to hold it in place. This will allow the
pump to “float” and minimize the transfer of barge deck or platform distortion into the
frame.

Installation of The Drive
The drive between the mud pumps and the power source, whether V-belts or multiwidth
chains, should be installed with the greatest care to assure maximum operating life with
minimum of unexpected shutdowns due to drive failures.
When installing the drive sheave or sprocket, make sure all grease or rust preventative is
removed from the shaft and the bore of the drive. Remove all burrs or rough spots from
the shaft, key, and keyway. Fit key to the keyways in both the shaft and drive and install
key into shaft keyway.Coat pinion shaft with a light coating of anti-adhesive compound or light oil and install the
drive sheave or sprocket hub. Tighten hub bolts as indicated below:
When a wrench or length of pipe is used to increase leverage in tightening draw-up bolts,
it is imperative to adhere to the wrench torque values given in the chart below. This
adherence is important, because in mounting the hub, the tightening force on the bolts is
multiplied many times by the wedging action of the tapered surface. This action
compresses the hub for a snug fit on the shaft. If the bolt-tightening forces are extreme,
bursting pressure is created in the hub of the mounted pulley, this pressure may cause the
pulley to crack. The hub bolts should always be tightened alternately and progressively.
