mud pump liner size pressure in stock

Rig pump output, normally in volume per stroke, of mud pumps on the rig is  one of important figures that we really need to know because we will use pump out put figures to calculate many parameters such as bottom up strokes,  wash out depth, tracking drilling fluid, etc. In this post, you will learn how to calculate pump out put for triplex pump and duplex pump in bothOilfield and Metric Unit.

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.

Mud pump liner selection in today"s drilling operations seldom (at best) considers electrical implications. Perhaps, with more available useful information about the relationships between mud pump liner size and operational effects on the electrical system, certain potential problems can be avoided. The intent of this paper is to develop those relationships and show how they affect an electrical system on example SCR rigs.Introduction

There, seems to be little consideration for the relationships between liner size and demand on a rig"s engine/generator set(s). Yet, consideration for this relationship can prove to be very helpful to drillers and operators in efficiency of a rig"s electrical system. In order to develop the relationships and help drillers and operators understand the importance of each, relationships between liner size, pump speed, pump pressure, and electrical power will be developed. Only basic physical laws will be used to develop the relationships; and, once developed, the relationships are readily applied to realistic examples utilizing a mud pump manufacturer"s pump data. Finally, conclusions will be drawn from the examples.DEVELOPMENT OF RELATIONSHIPS BASIC RELATIONSHIPS

Bi-metal liners (double metal liners) are made of forged steel shell and wear-resistant sleeve of high chromium iron. In the production process, the size accuracy should be strictly controlled, which can ensure that they can be easily and stably installed. The inner sleeve with high finish and hardness is wear-resistant, corrosion-resistant and has a long service life. The bi-metal liners are suitable for a lot of bad working conditions. Its service life is more than 800 hours.

Ceramic Liners are made of a ceramic inner sleeve and a forged steel outer shell. The service life of ceramic liners is about 4000 to 10000 hours, the minimum time is at least 2000 hours, which is a lot more than bi-metal liners. Because of the phase transformation toughen technology, the ceramic liners have the features of wear-resistance, erosion-resistance, high-pressure-resistance, high hardness and strength. Zirconia type and Alumina type are common type of ceramic sleeve. Compared with Alumina type, Zirconia type liners have better toughness properties and a much longer service life. Piston wear and water consumption for lubrication can be reduced as well.

Function: Mud Pump Liner also called the cylinder liner. The cylinder liner is the core accessory of the mud pump, which has the functions of storing mud, bearing pressure and completing the suction and discharge of mud. Because the cylinder liner is in direct contact with the mud, it is easy to be worn and corroded by the tiny sand particles, acid and alkali liquid in the mud during work. As a result, the inner diameter of the cylinder liner becomes larger, leakage occurs in the seal between the cylinder liner and the piston, and the pressure is reduced. The cylinder liner is scrapped eventually. Cylinder liner is a one-time wearable part that cannot be reused, and its life span directly affects the normal operation and cost of the drilling operation.

Bimetal Liners are also known as double metal liners. Forged steel pipe 45# (ASTM1045) is used for the outer sleeve, the normalizing hardness: 160BHN (HB180-200); elongation: 17%; tensile strength is not less than 85000PSI; yield strength is not less than 60000 PSI; The inner sleeve material is high chromium wear-resistant cast iron, with chromium content of 26-28%; thickness is 0.25 to 0.35 inches (6.35-8.89 mm), and the standard thickness is 7 mm. Usually, the service life is 800 hours under normal drilling conditions.

The inner liner is made of zirconia or aluminium oxide, and the outer sleeve is made of 45# (ASTM1045) forged steel. It has the advantages of more wear resistance, corrosion resistance, high-pressure resistance, high-temperature resistance, high strength and high hardness than metal cylinder liners. The service life is more than 4000 hours under normal drilling conditions.

The piston assembly is one of the main parts of the hydraulic end system of the mud pump, and it is also one of the vulnerable parts of the drilling work. The discharge pressure of the mud pump is generated by the reciprocating linear movement of the piston assembly in the piston.

NBR rubber is suitable for an ordinary drilling working environment with working pressure below 20Mpa, and the working temperature is not higher than 120℃. Excellent wear resistance, chemical resistance and long service life.

Polyurethane rubber has excellent oil resistance and wear resistance. The working temperature is not higher than 120℃, which is suitable for oil-based mud with working pressure below 35Mpa and working environment with high sand content.

The discharge pressure is routed to the closer mud tank, via a 3” XXS line clamped strongly on tank side . Mud is flowing into the mud tank until line bled off, bearing in mind that minimum slope is required to avoid mud settling in pipe ( around 1 inch/meter).

Pressure relief valves are set usually to 90% of the maximum working pressure of the liners in use. Read carefully manufacturer chart for pressure setting versus size of liners.

With a low pressure setting, ie, 1000psi, by adjusting the top nylon self lock nut to move on the vertical scale to get the same setting than the scale.

Discharge pressure losses close to the maximum preset pressure.The Pressure relief valves are usually installed on a upper point of the discharge side of the mud pumps.

The pressure relief valve can be reset, if not damaged during the release of pressure. Special care should be taken if no working platform available to access the PRV.[/fusion_text][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
