mud pump pulsation dampener function made in china

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.

In order to reduce the fluctuation of pressure and displacement of the drilling mud pump, air bag are usually installed on the discharge line. The air bag manufactured by our company has advanced structure and reliable performance, which can make the mud pump achieve the best inhalation effect and is widely used in petroleum, high-pressure pipeline of chemical transportation. This product can also be used as a stabilizer and shock absorber for air extractors.

The pulsation dampener can be divided into discharge pulsation dampener and Suction Dampener.Discharge pulsation dampener- reduces displacement of pump and fluctuation of pressure.

In order to reduce the pressure and displacement of drilling mud pumps, air bags are usually installed on the discharge pipeline. The suction air bags produced by our company have advanced structure and reliable performance, which can make the mud pump achieve the best suction. The effect is widely used in high-pressure pipelines for petroleum and chemical transportation. It can balance the peak pressure of high-pressure fluid in mud pumps, stabilize the pressure, and reduce losses. This product can also be used as a stabilizer and shock absorber for air extractors.

The mud pump is installed on the discharge line, which can balance the peak pressure of the high pressure fluid of the mud pump, play a role in stabilizing the pressure, reducing losses and ensuring safety, so that the mud pump can achieve the best suction effect.

Drain buffer: Installed at the drain end of pumps and compressors, it can avoid fatigue damage of cylinder pistons, valves, bases and pipelines due to pressure fluctuations, thereby extending the service life of the equipment.

Reverse Oscillation: When the head of the water pump reaches a certain height, the reverse oscillation caused by the impact of the fluid into the pump valve will cause the pump to suddenly shut down. A suction air bag is installed to absorb part of the vibration.

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.

The function of the air bag capsule on the mud pump is to use the volume of the air bag itself to continuously store and compensate the liquid discharged to a part of the pump in the pipeline to reduce the passiveness due to the pumped liquid. When the instantaneous displacement of the mud pump increases above its average displacement, the instantaneous pressure in the discharge line rises, and the gas volume in the air bag is compressed.

Mud pump pulsation dampener is the mud pump discharge end main component, installs in the hydraulic end discharge pipe one end, plays the stable pressure and the pressure compensation function, the air bag work pressure is the mud pump work pressure 80%.Attention should be paid to the use of air bag, must be the first pressure relief.The mud pump of F500/F800 USES kb-45 air bag, and the mud pump of F1000/F1300/F1600 USES kb-75 air bag.The middle tie rod produced by our company is made of 35CrMo material, which has a smooth surface after chrome plating and fine grinding, greatly improving the wear resistance and corrosion resistance.

Proper installation and use of pulsation dampener can effectively reduce pressure fluctuations in the discharge system, thus achieving a more uniform fluid flow.In order to achieve a high service life of the air bag, always maintain the recommended ratio between the pump pressure and the air bag precharge pressure (generally not more than 2/3 of the pump discharge pressure, the maximum should not exceed 4.5mpa).

Warning: 1. Only compressed nitrogen or compressed air can be used when charging -- flammable and explosive gases such as oxygen or hydrogen cannot be used.2. In the maintenance of air bag, air bag pressure must be zero, the pump pressure must be zero.Cannot rely on the pressure gauge to judge, because the residual pressure is small, the pressure gauge can not be displayed, but this low pressure will also lead to accidents!

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.

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.

This equipment plays an important role as an accessory to Yamada air-operated double diaphragm pumps. The pulsation dampener serves to reduce pulsation produced in operation and to assure stable discharge flow and pressure.

When pulsations occur with pump operation, it will result in the pressure in Chamber Bbeing greater than that in Chamber A. The diaphragm will act as an air cushion and automatically adjust to this pressure change and absorb the pulsations.

This operation will shift the center rod position upwards and allow more air in Chamber Athrough the air inlet, returning the diaphragm to a neutral position. If liquid pressure decreases, air pressure in Chamber Acauses the diaphragm to move downward, shifting shaft location and changing valve position, releasing excess air pressure in Chamber Awhich returns diaphragm to a neutral position. This action causes a reduction in surges and pulsation caused by a air operated double diaphragm pumps
