function of mud pump price
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. A mud pump is an important part of the equipment used for oil well drilling.
Mud pumps can be divided into single-acting pump and double-acting pump according to the completion times of the suction and drainage acting in one cycle of the piston"s reciprocating motion.
Mud pumps come in a variety of sizes and configurations but for the typical petroleum drilling rig, the triplex (three piston/plunger) mud pump is used. Duplex mud pumps (two piston/plungers) have generally been replaced by the triplex pump, but are still common in developing countries. Two later developments are the hex pump with six vertical pistons/plungers, and various quintuplexes with five horizontal piston/plungers. The advantages that these new pumps have over convention triplex pumps is a lower mud noise which assists with better measurement while drilling (MWD) and logging while drilling (LWD) decoding.
The fluid end produces the pumping process with valves, pistons, and liners. Because these components are high-wear items, modern pumps are designed to allow quick replacement of these parts.
To reduce severe vibration caused by the pumping process, these pumps incorporate both a suction and discharge pulsation dampener. These are connected to the inlet and outlet of the fluid end.
The power end converts the rotation of the drive shaft to the reciprocating motion of the pistons. In most cases a crosshead crank gear is used for this.
Displacement is calculated as discharged liters per minute. It is related to the drilling hole diameter and the return speed of drilling fluid from the bottom of the hole, i.e. the larger the diameter of drilling hole, the larger the desired displacement. The return speed of drilling fluid should wash away the debris and rock powder cut by the drill from the bottom of the hole in a timely manner, and reliably carry them to the earth"s surface. When drilling geological core, the speed is generally in range of 0.4 to 1.0 m^3/min.
The pressure of the pump depends on the depth of the drilling hole, the resistance of flushing fluid (drilling fluid) through the channel, as well as the nature of the conveying drilling fluid. The deeper the drilling hole and the greater the pipeline resistance, the higher the pressure needed.
With the changes of drilling hole diameter and depth, the displacement of the pump can be adjusted accordingly. In the mud pump mechanism, the gearbox or hydraulic motor is equipped to adjust its speed and displacement. In order to accurately measure the changes in pressure and displacement, a flow meter and pressure gauge are installed in the mud pump.
The construction department should have a special maintenance worker that is responsible for the maintenance and repair of the machine. Mud pumps and other mechanical equipment should be inspected and maintained on a scheduled and timely basis to find and address problems ahead of time, in order to avoid unscheduled shutdown. The worker should attend to the size of the sediment particles; if large particles are found, the mud pump parts should be checked frequently for wear, to see if they need to be repaired or replaced. The wearing parts for mud pumps include pump casing, bearings, impeller, piston, liner, etc. Advanced anti-wear measures should be adopted to increase the service life of the wearing parts, which can reduce the investment cost of the project, and improve production efficiency. At the same time, wearing parts and other mud pump parts should be repaired rather than replaced when possible.
Pump body thick. The pump body is made of high quality pig iron, durable and equipped with a thickened base. Thickened impeller, wear-resistant and dry rotating.
(Place the vertical mud pump upright or tilted in the liquid. Make sure the pump case is completely submerged in water. In addition, the motor part can not be immersed in water.)
Sewage pump is mainly used for industrial sewage, sewage treatment, in environmental protection has played a great role. The sewage pump is also a sewage pump with a cutting wheel, so the sewage pump can cut up the dirt, and then the sewage is extracted clean. Mud pump without cutting impeller, mostly used for pumping mud. The two main performance parameters of mud pump are displacement and pressure, displacement to discharge a number of liters per minute calculation, and drilling diameter and the required flushing fluid from the bottom of the hole back speed, that is, the larger the aperture, the larger the required displacement. The upward return velocity of the flushing fluid is required to flush cuttings and rock powders removed from the bottom of the hole in time and carry them reliably to the surface. By drilling and pumping, the mud under the ground can be obtained.

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. A mud pump is an important part of the equipment used for oil well drilling and manufactured according to API specification 7K.
The advantages of the drilling mud pump include the ability to move high-solids-content fluids laden with abrasives, the ability to pump large particles, ease of operation and maintenance, reliability, and the ability to operate over a wide range of pressures and flow rates by changing the diameter of pump liners and pistons.
As an important equipment for oilfield drilling operation, a drilling mud pump delivers circulating high-pressure drilling fluid or drilling mud to the bottom of the oil well, flushes the bottom of the well, breaks the rock, cools, lubricates and clean the drill bit, and carries the cuttings back to the ground.
The drilling mud is also used to suspend and carry out drill cuttings from the drill bits as it is brought in and out of the hole. This ensures that the drill bit does not clog and overheat, and makes the entire drilling operation smooth and safe.
Rotational power is supplied to the mud pump through an external power source like a diesel engine or electric motor. The power end of the mud pump converts the rotational energy through a crankshaft to a reciprocating motion of pistons.
The pistons move back and forth in mud pump liners, exerting a force on the cylinder chamber. During the retraction of the piston, valves open to allow the fluid to be drawn into the cylinder. Once the piston has fully retracted, it is pushed back into the cylinder.
At this time the intake valves are closed and the exhaust valves open, allowing the piston to force the fluid out of the cylinder under pressure. Once the piston reaches its maximum depth into the cylinder, the exhaust valves close and the process repeats.

Mud pump is mainly used for geological drilling, geological engineering construction and foundation treatment of low and medium pressure grouting pump, etc. Mud pump is a machine that sends mud or water to the borehole during the drilling process. Mud pump is an important part of drilling equipment. All major businesses have mud pump parts for sale.
The main function of mud pump is to inject mud into the well along with the bit during the drilling process. It plays the role of cooling the drill bit, cleaning the drilling tool, fixing the well wall, driving drilling, and bringing the cuttings back to the surface after drilling.
In the commonly used positive circulation drilling, the mud pump sends the surface flushing medium-- clean water, mud or polymer flushing fluid to the end of the drill bit through the high pressure hose faucet and the center hole of the drill string under a certain pressure. Therefore, the purpose of cooling the drill bit and removing and conveying the cuttings to the surface is achieved.
Petroleum drilling mud pump is a kind of volumetric mud pump. Its basic working principle is that the volume of the sealed working chamber (mud pump cylinder liner) is periodically changed to convert the original mechanical energy into the pressure energy of the liquid to complete the operation.
The specific process relies on the reciprocating motion of the mud pump piston in the cylinder liner to make the volume of the working chamber in the cylinder liner change periodically. The mud pump cylinder liner is isolated from the outside world by means of a sealing device such as a seal ring, and communicates or closes with the pipeline through the pump valve (suction valve or discharge valve), which shows the importance of the mud pump cylinder liner. The three-cylinder mud pumps currently on the market are equipped with three cylinder sleeves.
Positive displacements pumps are generally used on drilling rigs to pump high pressure and high volume of drilling fluids throughout a drilling system. There are several reasons why the positive displacement mud pumps are used on the rigs.
The duplex pumps (Figure 1) have two cylinders with double acting. It means that pistons move back and take in drilling mud through open intake valve and other sides of the same pistons, the pistons push mud out through the discharge valves.
When the piston rod is moved forward, one of intake valves is lift to allow fluid to come in and one of the discharge valve is pushed up therefore the drilling mud is pumped out of the pump (Figure 2).
On the other hand, when the piston rod is moved backward drilling fluid is still pumped. The other intake and discharge valve will be opened (Figure 3).
The triplex pumps have three cylinders with single acting. The pistons are moved back and pull in drilling mud through open intake valves. When the pistons are moved forward and the drilling fluid is pushed out through open discharge valves.
On the contrary when the piston rods are moved backward, the intake valve are opened allowing drilling fluid coming into the pump (Figure 6). This video below shows how a triplex mud pump works.
Because each pump has power rating limit as 1600 hp, this will limit capability of pump. It means that you cannot pump at high rate and high pressure over what the pump can do. Use of a small liner will increase discharge pressure however the flow rate is reduces. Conversely, if a bigger liner is used to deliver more flow rate, maximum pump pressure will decrease.
As you can see, you can have 7500 psi with 4.5” liner but the maximum flow rate is only 297 GPM. If the biggest size of liner (7.25”) is used, the pump pressure is only 3200 psi.
Finally, we hope that this article would give you more understanding about the general idea of drilling mud pumps. Please feel free to add more comments.
The crank gear and connecting rods drive a rotary movement that is transferred by the motor transmission. The pressure is produced by the piston in the cylinder due to which the mud is sucked. Following the operation, the suction valve is closed when it moves to left. As the pressure increase in the pipeline, the valve is forced to open and mud is released.
In accordance with the operating liquid displacer type being incorporated, the pumps are subdivided into piston units and plunger-type units. The liquid discharge uniformity is independent of head. The pumping plants are used actively for the processes with the liquids containing solid inclusions in high amounts. Incorporating the self-suction function in piston unit, the liquid is sucked and discharged twice in mud pumps during the single shaft turn, making themselves the double-action pumps whereas, the mud plunger pumps are single-action pumps where the liquid is sucked and discharged only once during a shaft turn.
The single direct-action three-piston pumps prove to be better than other types of drilling. These pumps demonstrate much more uniformity in mud delivery, lesser weight, and easy mounting when compared with two-cylinder units.
Depending on the number of cylinders, the pumping plants are classified into the following categories, single-cylinder, double-cylinder, three-cylinder and multi-cylinder pumping plants. These cylinders may be vertical or horizontal. Comparatively, the multi-cylinder pumping plants will cost higher but don’t feature any significant advantages other than the single-cylinder.
When drilling, there might occur the necessity of mud pumping out- and flushing-out, so there are various types of pumps available for such operations which are required to be installed on drilling rigs.
Sucker-rod pumps: In sucker-rod pumps, the pumpjack is a driver. This pump is installed at the bottom of the well. The reciprocating movements of the pumpjack are converted into liquid flow by the pump, which results in delivery of liquid on the surface. These pumps move oil with various admixtures demonstrating high level of capacity.
Screw pumps:The screw pumps are small-sized and are generally used to deliver mud into a centrifuge. These pumps have the rotor and stator as the major structural components and the material used to manufacture these components suit right for smooth pumping of liquids with solid inclusions and high level of viscosity. The pumped liquid flows with stable pressure, shaft slowly and the flow is free of vortexes. These pumps comparatively require minimum service.
Well pumps: These pumps are submerged into wells. The ground part of the plant is a transformer substation equipped for start and adjustment. The pump has a vertical structure, with a fixed cylinder and single-action. A plunger and valve are moving parts. The pumped liquid may contain water content of up to 99% at the temperature as high as 130ºC.
All the mud pumps have few general advantages that include the capability to process liquids and substances with high level of viscosity and with admixtures. Also, enabling the smooth flow of substances, free of pulsations or suspensions mixing are counted under the major advantages of incorporating mud pumps. The pumps have high suction power and small weight, easing out the transportation and installation at remote oil fields. They are highly reliable and also affordable.
There are various types of mud pumps available for different purposes. So, it is important to incorporate the right one for your purpose. A Professional help in getting the right mud pump would be a good and safe option.
Mud Pump Pulsation Dampener is usually installed on the discharge line to reduce the fluctuation of pressure and displacement of the drilling mud pump.
Mud Pump Pulsation Dampener is a pneumatic device built into the outflow line of each UUD pump to dampen the pressure fluctuations resulting from the action of the pump. Although presented as a surge tank, this device is really a device that can be tuned to greatly diminish the output pulsations transmitted downstream from the mud pump. Unfortunately, the effectiveness of the pulsation dampener is a function of both output pump pressure and frequency of the pump pulsations.
