The BW250 mud pump belongs to a horizontal three cylinder
reciprocating single acting piston pump, and its working principle
is as follows:
Power conversion: The crankshaft at the power end begins to rotate
under the drive of a power source (such as an electric motor,
diesel engine, etc.). The crankshaft is equipped with three
connecting rods of the same size, each connected to the piston
through a crosshead and piston rod. In this way, the rotational
motion of the crankshaft is converted into the reciprocating linear
motion of the piston inside the pump cylinder through the
connecting rod, crosshead, and piston rod.
Inhalation process: When the piston moves backwards, the volume
inside the pump cylinder increases, the pressure decreases, and
negative pressure is formed. At this time, the mud enters the pump
cylinder through the suction pipe under the action of external
atmospheric pressure. One end of the suction pipe is inserted into
the mud source such as the mud pit, and the other end is connected
to the suction valve of the pump. The mud smoothly enters the pump
cylinder under the pressure difference.
Discharge process: When the piston moves forward, the volume inside
the pump cylinder decreases, the mud is squeezed, and the pressure
increases. Under pressure, the mud pushes the discharge valve open
and is discharged from the pump body through the drainage pipe,
transported to the required locations such as drilling and grouting
positions. In this way, the piston continuously performs
reciprocating motion, and the mud is continuously sucked in and
discharged, achieving continuous transportation of the mud.
The daily maintenance of BW250 mud pump needs to be carried out from multiple aspects, and the following are some precautions:
1. Power end maintenance
Check the lubricating oil
Check the oil level of the power end lubricating oil daily to
ensure that it is within the range specified by the oil gauge. If
it is insufficient, it should 2. be added in a timely manner.
Check the quality of the lubricating oil every certain working time
(usually 200-300 hours). If the oil becomes black, thin, or has
impurities, it should be replaced in a timely manner.
Check the transmission components
Regularly check the tightness of the belt to ensure smooth
transmission and no slipping. Loose belts can affect transmission
efficiency, while tight 3. belts can increase wear on bearings and
belts.
Regularly check whether the connecting bolts of the crankshaft,
connecting rod, crosshead, piston rod and other components are
loose. If they are loose, they should be tightened in a timely
manner to prevent component damage caused by looseness.
Pay attention to whether there are any abnormal sounds during the
operation of the power end. If any abnormal sounds such as
collision or friction are found, the machine should be stopped
immediately for inspection and troubleshooting.
Overall maintenance
1. Cleaning equipment
Regularly cleaning the surface of the mud pump of mud, oil, and
dust, keeping the appearance of the equipment clean, is beneficial
for heat dissipation and timely detection of equipment problems.
Clean up the debris around the equipment, keep the working
environment clean, and facilitate operation and maintenance.
2. Check the sealing components
Check all sealing parts, such as shaft seals and pipe joint seals,
for any leakage. If there is any leakage, replace the seals in a
timely manner.
Pay attention to whether the dust seal ring on the pull rod is
intact. If it is damaged, it should be replaced in a timely manner
to prevent mud from entering the power end.
3. Check the piping system
Check whether the inlet and outlet pipes are damaged, aged,
blocked, etc. If there are any problems, they should be repaired or
replaced in a 3. timely manner.
4. Ensure that the connection of the pipeline is firm, without
looseness or leakage, to avoid affecting the normal operation of
the mud pump due to pipeline problems.
