How do I choose a mud pump?
When choosing a size and type of mud pump for your drilling project, there are several factors to consider. These would include not only cost and size of pump that best fits your drilling rig, but also the diameter, depth and hole conditions you are drilling through.
What is mud pump used for?
A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus.
What is a high pressure mud pump?
A mud pump or drilling mud pump is used to circulate drilling mud on a drilling rig at high pressure. The mud is circulated down through the drill string, and back through the annulus at high pressures. Mud pumps are typically positive displacement pumps, otherwise known as reciprocating pumps.
What is the best pump for sludge?
Which Positive Displacement Pump Is Best For Wastewater Sludge?
- Centrifugal pumps are good for low viscosity sludge with very little solids.
- Progressive cavity pumps are great for sludge.
- Rotary lobe pumps are great for high viscosity fluids.
What is a triplex mud pump?
A triplex pump is a classification of mud pump commonly used for oil drilling. The primary purpose of a mud pump is to circulate the mud, also called drilling fluid, during drilling operations. It works by forcing drilling fluid down the hollow drill string and back up through the annulus.
How do you calculate the pressure of a mud pump?
Pump Pressure and Pump Stroke Relationship
- New circulating pressure in psi = present circulating pressure in psi x (new pump rate in spm ÷ old pump rate in spm) 2
- Example: Determine the new circulating pressure, psi using the following data:
- Factor (n) = log (pressure 1 ÷ pressure 2) ÷ log (pump rate 1÷pump rate 2)
What is meant by mud pumping?
Joints form the break in the cement concrete pavement. This causes infiltration of water through them. The infiltration of water through the joints damages the soil sub-grade and the soil slurry ejects out through the joints under heavy wheel loads. This phenomenon is known as mud pumping.
What type of pump is used for sludge?
Progressive cavity pumps are great for sludge. They impart little to no shear on the sludge, and generate low pulsation rates.
What kind of pump can pump mud?
Diaphragm pumps are most commonly used to pump sludge and extremely abrasive liquids. A common example would be draining a pond because it can handle the muck and mud on the bottom, as well as the water, leaves, and weeds.
What is the difference between duplex and triplex pump?
A pump that has double-action strokes in two cylinders is called a duplex pump (Figure 1.2). A pump that has single-action strokes in three cylinders is called a triplex pump (Figure 1.3).
