mud pump dampener function for sale

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.

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 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.

Pulsation Dampener (Surge damper) is installed on the discharge pipeline of the mud pump to balance the peak value of the high-pressure fluid pressure of the mud pump, so as to stabilize the pressure and reduce losses.

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 discharge dampener is designed and installed in the pipe to help absorb this pressure spike. The dampener consists of a vessel filled with gas or compressible material. When there are sudden changes in flow, the compressible material is able to compress and expand, similar to jumping onto your bed. The video below demonstrates the effects with and without a dampener.

By installing a pulsation dampener, the intensity of these spikes are reduced to controlled levels.A dampener should be sized and installed in all piping that may experience a harmful level of pressure spikes.

Pulsation dampeners can be purchased in a variety of shapes, sizes, and designs. It is important to size a pulsation dampener for a specific application. Incorrect sizing or incompatible materials may cause a danger to equipment, systems, and personnel.

Membrane Pulsation Dampener: A membrane-type dampener provides a solid separation between the pumping fluid and the compressible gas. The membrane resides within the dampener and allows for the pressure to be transferred to the gas, without any mixing of the gas into the fluid.

Bladder Pulsation Dampener: A bladder type dampener fully encloses the compressible gas within a bladder. This setup ensures there is no leakage of the gas into the pumping fluid. The pressure pulsations are transferred to the gas as the bladder expands and contracts.

Bellows Pulsation Dampener: A bellows-type dampener works the same way as a bladder type dampener. However, by using a bellows-type design, it can be made with other types of materials such as PTFE or Stainless Steel. This type of dampening system is used when pumping corrosive materials that may deteriorate more common materials.

Pressure Vessel Style: A pressure vessel dampener, sometimes referred to as a “zero maintenance” style dampener does not use any moving parts. They are only effective at very high pressures. Fluids, including water, do have some degree of compressibility. Pressure Vessel Style dampeners allow for the pressure of the fluid to be dissipated within the vessel by the small amount of compressibility within the pumping fluid. In very high-pressure applications, a pressure vessel style dampener may be the only type of dampener available. It is important to note that this style of dampener does not operate as effectively as other types of dampeners.

Flexible piping: Although it is not recommended, flexible piping or hose can act as a pulsation dampener in emergency situations. As the fluid flow changes, the flexible piping is able to “move” and allow a dampening effect on the fluid. Flexible piping still requires proper sizing to reduce pressure spikes. Improper usage may result in damage to equipment and endangerment of equipment operators.

Equipment that rapidly changes flow rates is recommended to have a pulsation dampener. Plunger pumps, for example, have a highly variable flow rate. The average flow rate of a plunger pump can be accurately predicted. However, each rotation of the crankshaft produces several changes in flow velocities.

When a plunger pump is running slowly, these pressure spikes can be ignored. In most cases, they will not produce enough of a spike to create damage. When the pump is running at full speed, this full cycle is taking place many times per second. The pressure spikes caused by these sudden changes will likely need a pulsation dampener.

The image above shows the visible pulsations created by a reciprocating quintuplex pump. Using flexible hoses on the inlet and outlet, the pressure fluctuations through the hose can easily be seen. Since steel piping is more rigid, it may be more difficult to visually see pressure vibrations before damage to piping and the surrounding systems takes place. It is important to correctly determine if a dampener is needed and to correctly install the required size before operating the pump system.

It is important to note that pressure pulsations are not a function of pressure. The operational pressures of a system have very little effect on the resulting pressure pulsations. Both suction and discharge sides of a reciprocating pump are susceptible to pulsations and resulting damage. Both the suction and discharge dampeners operate independently of each other. Proper sizing and installation of both suction and discharge dampeners are required for proper protection of pumping equipment and systems.

The OEM series PZ mud pump features a pleasing shape, advanced design, reasonable structure, and high efficiency. At power end, pinion shaft and bull gear are both hard teeth, wear-resistant, and transmission stable.

All parts at the power end except the lubrication oil pump and all parts of the fluid end are completely exchangeable with OEM pumps from the United States.

The pump frame is gang welding on casting and steel–plate construction. The bearing housings of the crankshaft, the transmission shaft, and guides seats are made of steel castings and are welded to the frame after rough–machined. They are stress–relieved through heat-treated aging after welded.

The cylinder is made of VD refined forged steel. And the three valves on each pump are exchangeable. The direct cylinder (the valve on the valve) design may reduce the volume and may improve the efficiency of it. As the customer required, we may nickel plating the surface, which may prevent the cylinder from erosion.

The piston rod conforms to the spec API-7K. The piston is fixed with the 1-1/2＂locking nuts. Without weariness of the piston and with the piston through the separated water tank, the piston spray pump may spray water or erosion-proof water to lubricate and to cool.

The discharge site of the pump involves a discharge pulsation dampener, relief valve, and discharge screen. The suction port is 12” flange. Three cylinders at the fluid end are of through-way stepwise structure, realize suction and discharge. The fluid end is composed of three fluid modules (cylinders), each of which is a sectional and communicating construction. The suction and discharge are accomplished by suction and discharge pipes. The suction and discharge valves are vertically aligned with each other to minimize the volumetric clearance.

The discharge pulsation dampener is spherical and pre–pressured. It’s Max. The working pressure is 5000PSI, and the volume is 75L (20 gallons). The pulsation dampener is connected to the air filler and to the pressure gauge, using 3/4” – 14NPT and 1/4” – 18NPT respectively.

Spray system includes a spray pump, cooling water box, and spray hose. It function involves cooling and washing cylinder liner and piston, which will extend liner and piston’s service life.

The spray system is a kind of eccentric pump, imported from the United States. The spray pump can be V-belt driven or electric driven. Use water as a cooling lubricant.

The power end adopts force lubrication and splash lubrication. The gear oil pump in the reservoir transfers pressure oil to the crosshead, intermediate rod, guide, and each bearing through lubricating lines. The working status of the gear oil pump can be checked through the vacuum gauge aside from the frame.

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.
