how does a mud pump pulsation dampener work price

All pulsation dampeners utilize one of two methods for mitigating energy produced by reciprocating pumps; compression or exchange. The traditional gas-charged dampeners use a compressible gas cushion, either by a gas over liquid or gas-filled diaphragms, bladders, or cartridge. As the reciprocating pump produces pressure spikes, the gas compresses, thus absorbing the pressure difference and smoothing the pumped media flow. For maintenance free pulsation dampeners, rely on energy exchange. There is a common misconception regarding maintenance free pulsation control devices that the pumped media is compressible enough to absorb the reciprocating pumps’ pressure spikes. This is not true. However, the maintenance free pulsation dampeners work by utilizing the kinetic energy exchange. This kinetic energy exchange can only happen if the pulsation dampener’s volume is large enough to dissipate enough energy to reduce the adverse effects caused by the reciprocating pump. This is why maintenance free pulsation devices require massive volumes to be effective. Sigma Drilling Technologies has developed a pulsation dampening system that utilizes both methods for reducing the harmful effects of positive displacement pumps, both compression and exchange.

A properly serviced pulsation dampener is critical for your mud pumps’ efficiency, safety, and performance. Unfortunately, there aren’t many resources available to educate personnel on executing safe and effective servicing procedures. Please review the following steps with your personnel for safe pulsation dampener maintenance.

Should you or your personnel have any questions regarding pulsation dampener maintenance, please don’t hesitate to ask. Sigma is more than happy to help you to ensure safe and proper care is being completed on your pulsation dampening equipment.

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.

A pulsation damper is an equipment capable of playing a very important role in the use of double diaphragm pumps. As can be seen from the name, this accessory is aimed at reducing pulsations and vibrations during pump operation, thus ensuring a “continuous” and precisely non-pulsed flow rate and a reduction of vibrations on the system pipes.

A pulsation damper works thanks to the same compressed air that feeds the pump. The compressed air introduced into the counter-pressure chamber behind the membrane creates a pneumatic damping cushion that self-adjusts according to the stress exerted by the pressure pulse of the fluid generated by the pump.

EQUAFLUX dampers are used with fluids of high apparent viscosity even in the presence of solid parts in suspension. They automatically adapt to the system conditions, without manual adjustment or calibration. The high ability to minimize pulsations, vibrations and water hammers makes this component a suitable equipment for safeguarding the system, giving regularity to the outgoing flow. The wide choice of construction materials allows you to determine the best chemical compatibility with the fluid and / or the environment without neglecting the correct temperature range. The dampers are also available for use in a potentially explosive environment (ATEX certification).

Inside the hydraulic systems, the pulsations of the fluid can cause phenomena called water hammer consisting of pressure peaks caused by a sudden change in the flow rate inside the pipes or by the sudden closure of a valve. The effects of water hammer vary according to the size of the pipeline and the speed and density of the fluid but can often cause extensive damage to the elements of a system. To preserve the system from water hammer and vibrations, it is possible to use the pulsation dampers of the Equaflux series that can automatically adapt to the operating conditions of the pump.

Equaflux pulsation dampers are normally applied to pneumatic double diaphragm pumps. The latter, during the phases of use, can record pressure peaks which, if not controlled, can damage the elements of a system. The main benefits associated with the use of pulsation dampers can be summarized in the following points.

The application of diaphragm pumps equipped with pulsation dampers refer to the entire process industry: hydraulic systems, use in chemical transformation processes, use within the petrochemical, mining sectors and much more. The EQUAFLUX series is also available with ATEX certification and therefore can be used directly within sectors with the presence of explosive risks.

Pulsation dampers are very versatile tools whose use can vary according to the needs of the operating processes and application sectors. For this reason, a sales team is at your disposal to support you in choosing the most suitable configuration for your needs. Contact the Debem team now.

For more information about pulsation dampeners, we sat down with Brandon Dalrymple and Nathan Ackeret fromBlacoh Fluid Control(manufacturer of pulsation dampeners, surge suppressors, and inlet stabilizers), and asked them to answer a few of our customers’ most common questions about pulsation dampeners.

Pulsation dampeners absorb the energy from the pulse wave created by a positive displacement pump, much like a shock absorber on a vehicle. Absorbing those pulse waves protects pipe welds and supports, and system components from damage due to pressure or excess movement.

A pulsation dampener creates an area of low pressure in the system with enough volume to absorb the pulsation. The pulsation dampener has a membrane with a "cushion" of compressible gas/air behind it that flexes to absorb the pulse, allowing a laminar flow downstream of the dampener.

Pulsation dampeners are commonly used wherever a positive displacement pump discharges flow in an unsteady manner, and where the pulse is not desired for the piping system. Air operated double diaphragm, metering and hose/peristaltic pumps typically benefit from a pulsation dampener.

The type of pulsation dampener used is typically defined by where they are placed in the system, and what they need to do. For example, "pulsation dampeners" are on the downstream side of the pump, "inlet stabilizers" are on the inlet side of the pump, and an accumulator or "surge suppressor" is used next to a valve or other device that restricts the flow in a system.

This video shows where you would place an inlet stabilizer, and how it is used to reduce the pulsation with an air operated diaphragm pump in suction lift conditions.

If you"re experiencing problems with rattling pipes, intermittent flow, water hammer, or pulsations in your system, don"t ignore it. Take the steps necessary to control these symptoms to prevent system deterioration down the road.

Mud pump is one of the most critical equipment on the rig; therefore personnel on the rig must have good understanding about it. We’ve tried to find the good training about it but it is very difficult to find until we’ve seen this VDO training and it is a fantastic VDO training about the basic of mud pumps used in the oilfield. Total length of this VDO is about thirteen minutes and it is worth to watch it. You will learn about it so quickly. Additionally, we also add the full detailed transcripts which will acceleate the learning curve of learners.

Powerful mud pumps pick up mud from the suction tank and circulate the mud down hole, out the bit and back to the surface. Although rigs usually have two mud pumps and sometimes three or four, normally they use only one at a time. The others are mainly used as backup just in case one fails. Sometimes however the rig crew may compound the pumps, that is, they may use three or four pumps at the same time to move large volumes of mud when required.

Rigs use one of two types of mud pumps, Triplex pumps or Duplex pumps. Triplex pumps have three pistons that move back-and-forth in liners. Duplex pumps have two pistons move back and forth in liners.

Triplex pumps have many advantages they weight 30% less than a duplex of equal horsepower or kilowatts. The lighter weight parts are easier to handle and therefore easier to maintain. The other advantages include;

• One of the more important advantages of triplex over duplex pumps, is that they can move large volumes of mud at the higher pressure is required for modern deep hole drilling.

Triplex pumps are gradually phasing out duplex units. In a triplex pump, the pistons discharge mud only when they move forward in the liner. Then, when they moved back they draw in mud on the same side of the piston. Because of this, they are also called “single acting.” Single acting triplex pumps, pump mud at a relatively high speeds. Input horsepower ranges from 220 to 2200 or 164 to 1641 kW. Large pumps can pump over 1100 gallons per minute, over 4000 L per minute. Some big pumps have a maximum rated pressure of over 7000 psi over 50,000 kPa with 5 inch/127 mm liners.

Here is a schematic of a triplex pump. It has three pistons each moving in its own liner. It also has three intake valves and three discharge valves. It also has a pulsation dampener in the discharge line.

Look at the piston at left, it has just completed pushing mud out of the liner through the open discharge valve. The piston is at its maximum point of forward travel. The other two pistons are at other positions in their travel and are also pumping mud. But for now, concentrate on the left one to understand how the pump works. The left piston has completed its backstroke drawing in mud through the open intake valve. As the piston moved back it instead of the intake valve off its seat and drew mud in. A strong spring holds the discharge above closed. The left piston has moved forward pushing mud through the now open discharge valve. A strong spring holds the intake valve closed. They left piston has completed its forward stroke they form the length of the liner completely discharging the mud from it. All three pistons work together to keep a continuous flow of mud coming into and out of the pump.

Crewmembers can change the liners and pistons. Not only can they replace worn out ones, they can also install different sizes. Generally they use large liners and pistons when the pump needs to move large volumes of mud at relatively low pressure. They use a small liners and pistons when the pump needs to move smaller volumes of mud at a relatively high pressure.

In a duplex pump, pistons discharge mud on one side of the piston and at the same time, take in mud on the other side. Notice the top piston and the liner. As the piston moves forward, it discharges mud on one side as it draws in mud on the other then as it moves back, it discharges mud on the other side and draws in mud on the side it at had earlier discharge it. Duplex pumps are therefore double acting.

Double acting pumps move more mud on a single stroke than a triplex. However, because of they are double acting they have a seal around the piston rod. This seal keeps them from moving as fast as a triplex. Input horsepower ranges from 190 to 1790 hp or from 142 to 1335 kW. The largest pumps maximum rated working pressure is about 5000 psi, almost 35,000 kPa with 6 inch/152 mm linings.

A mud pump has a fluid end, our end and intake and the discharge valves. The fluid end of the pump contains the pistons with liners which take in or discharge the fluid or mud. The pump pistons draw in mud through the intake valves and push mud out through the discharge valves.

The power end houses the large crankshaft and gear assembly that moves the piston assemblies on the fluid end. Pumps are powered by a pump motor. Large modern diesel/electric rigs use powerful electric motors to drive the pump. Mechanical rigs use chain drives or power bands (belts) from the rig’s engines and compounds to drive the pump.

A pulsation dampener connected to the pump’s discharge line smooths out surges created by the pistons as they discharge mud. This is a standard bladder type dampener. The bladder and the dampener body, separates pressurized nitrogen gas above from mud below. The bladder is made from synthetic rubber and is flexible. When mud discharge pressure presses against the bottom of the bladder, nitrogen pressure above the bladder resists it. This resistance smoothes out the surges of mud leaving the pump.

Here is the latest type of pulsation dampener, it does not have a bladder. It is a sphere about 4 feet or 1.2 m in diameter. It is built into the mud pump’s discharge line. The large chamber is form of mud. It has no moving parts so it does not need maintenance. The mud in the large volume sphere, absorbs this surges of mud leaving the pump.

A suction dampener smooths out the flow of mud entering into the pump. Crewmembers mount it on the triplex mud pump’s suction line. Inside the steel chamber is a air charged rubber bladder or diaphragm. The crew charges of the bladder about 10 to 15 psi/50 to 100 kPa. The suction dampener absorbs surges in the mud pump’s suction line caused by the fast-moving pump pistons. The pistons, constantly starts and stops the mud’s flow through the pump. At the other end of the charging line a suction pumps sends a smooth flow of mud to the pump’s intake. When the smooth flow meets the surging flow, the impact is absorbed by the dampener.

Workers always install a discharge pressure relief valve. They install it on the pump’s discharge side in or near the discharge line. If for some reason too much pressure builds up in the discharge line, perhaps the drill bit or annulus gets plugged, the relief valve opens. That opened above protects the mud pump and system damage from over pressure.

Some rig owners install a suction line relief valve. They install it on top of the suction line near the suction dampener. They mount it on top so that it won’t clog up with mud when the system is shut down. A suction relief valve protects the charging pump and the suction line dampener. A suction relief valve usually has a 2 inch or 50 mm seat opening. The installer normally adjusts it to 70 psi or 500 kPa relieving pressure. If both the suction and the discharged valves failed on the same side of the pump, high back flow or a pressure surge would occur. The high backflow could damage the charging pump or the suction line dampener. The discharge line is a high-pressure line through which the pump moves mud. From the discharge line, the mud goes through the stand pipe and rotary hose to the drill string equipment.

A Pulsation Dampener is an inline dampening device used to smooth out pulsations in a pump’s output. They are used alongside a pump as a mounted accessory to help achieve certain flow rates for an application.  They can be used with a variety of Positive Displacement Pumps which typically generate a pulsed flow (Diaphragm Pumps, Peristaltic Pumps, Dosing Pumps, Piston Pumps etc)

Pulsation Dampeners are required in some process applications when the customer needs smooth flow into the next phase of the production line, for example, to get an accurate reading through a flow meter or to fill a hopper consistently. On the flip side, Dampeners can be used to reduce water hammer effects through pipework. Water hammer is where the pump causes the pipes to vibrate and potentially fail, a smooth flow from a Pulsation Dampener reduces this.

For example, Diaphragm Pumps inherently produce a very turbulent discharge flow meaning that in some instances a Pulsation Dampeners are required to give a smooth pulse-free flow.

In the Tapflo UK range, we focus on Pulsation Dampeners for Diaphragm and Peristaltic Pumps, although we can also supply them for other pump technologies.

The Active Pulsation Dampener works by supplying an equal pressure to the pulsation supplied by the pump. The Dampener supplies this pressure during the low-pressure points of the pump’s operation, as the pressure drops between pump strokes creating a pulsating flow. The pressure supplied by the dampener decreases pressure variations, therefore producing a steady flow from your Diaphragm Pump. You can see the pressure drops and Pulsation Dampener benefits in action in the diagram below.

Tapflo supplied a 2” Air Operated Diaphragm Pump to a bleach factory, the customer used the T400 PTT for a couple of days and then called us to explain that the bleach line, running along the roof of his production facility, was shaking. Due to the nature of the product being pumped health and safety on site could not allow this to continue.

To support our Peristaltic Pump customers, Tapflo offers an in-line Pulsation Dampener for our PT and PTL Series’. They can reduce the pulsation of your PT Pump by as much as 90% to reduce the vibration and water hammer effects on pipework. Another benefit of this accessory is its ability to be installed on-site horizontally or vertically for flexible installation.

The Pulsation Dampener is composed of Pulsation Dampener Shell, Rubber Bladder( Diaphragm), Pressure Gauge, Angle Stop Valve(Charging Valve) and End Cover( Bottom Plate Gasket) etc.

1.-- Pulsation Dampener is forged with 4130 Low-Temperature Resistance Alloy Steel. 2.-- Pulsation Dampener has precise inside chamber size with surface roughness 6.3, increase the life span of the bladder.

Our custom-designed systems will absorb excess energy pulsing through the pump and piping system by creating a low-pressure area to dampen the excess shocks and vibrations. Because a pulsation dampener regulates the release of energy, your system will be better protected and run more smoothly. After installing a pulsation dampener, customers notice that their system:

When you choose to work with our team, we’ll help you find the right specifications across our product series, allowing us to customize features, including:

abstractNote = {Triplex pump flow naturally fluctuates due to the cyclic nature of the pump and other factors inherent in the system. Flow deficiency at the suction can lead to fluid separation and knock, and at both the suction and discharge, unsteady flow can lead to vibration and increased wear. Dampeners can steady these input and output fluctuations in flow and pressure to acceptable levels.},
