Features of mud pump MOTOR

Mud Motor:

1.Simple structure, easy disassembly and maintenance.

2.Smooth operation, low vibration and low noise.

3.It can transport high-concentration and high-viscosity (less than 10000PaS) suspension slurry.

4.Drilling fluid flows smoothly, without overflow, pulsation, agitation, and shearing of mud.

5.Exhaust pressure has nothing to do with speed; low flow can also maintain high discharge pressure.

6.The displacement is proportional to the speed, which can be adjusted by the shift mechanism or the motor.

7.Strong self-priming ability, can directly absorb liquid without bottom valve.

Maintenance

The construction department should have a dedicated maintenance worker who is responsible for the maintenance and repair of the machine. Mechanical equipment such as mud pumps should be inspected and maintained regularly and in a timely manner to find problems and solve them early to avoid unplanned downtime.Workers should pay attention to the size of sediment particles; if large particles are found, they should often check whether the parts of the mud pump are worn and see if they need to be repaired or replaced.The wearing parts of the mud pump include the pump casing, bearings, impellers, pistons, bushings, etc.Advanced anti-wear measures should be taken to improve the service life of the wearing parts, which can reduce project investment costs and improve production efficiency. At the same time, the wearing parts and other mud pump parts should be repaired instead of replaced as much as possible.

Mud motor

A mud motor (or drilling motor) is a progressive cavity pump (PCPD) placed in the drill string to provide additional power to the drill bit while drilling. PCPD pumps use drilling fluid (commonly known as drilling mud, or mud for short) to create eccentric motion in the power section of the motor and transmit it to the drill bit as concentric power. Mud motors use different rotor and stator configurations to provide optimum performance for the required drilling operation, often increasing the number of blades and length of the powertrain for greater horsepower. In some applications, compressed air or other gases may be used for mud motor input power. Normal rotation of the drill bit when using a mud motor can be from 60 rpm to over 100 rpm.

Fundamentals

Based on a principle developed by Rene Moineau, the theory states that a helical rotor with one or more blades will rotate eccentrically when the stator contains more blades than the rotor. The flow of fluid transmits power, allowing the assembly to rotate and turn the bit.
