[0001] PPS , Power Pumping System

[0002] Priorart:

[0003] Simply stated, a pump is a machine used to move liquid through a piping system and to raise the pressure of theliquid, today, pumps and their associated systems play a central role in all process operations in the energysector worldwide, these include oil, gas, petrochemical, chemical, power generation and water, together withindustriessuchasfoodprocessing, pharmaceutical, steel, paper, agriculture andmany others.

[0004] There are many different pump types. Pumps operate via two basic principles, roto dynamic and positivedisplacement, butthereare afew pumpdesigns outsidethiscategorization.

[0005] There are a wide range of pump types because some designs are better; more efficient or more consistent or lastlonger; at handling specific operating conditions or specific liquid properties. Each application should beassessed individually, on merit, when considering: -

[0006] I - Liquidproperties

[0007] 2- Allowableleakage

[0008] 3- Drivertype

[0009] 4- Installationarrangement

[0010] 5- Operatingefficiencyrequired

[0011] 6-Dutycycle

[0012] 7- Allowable noise level 8- Operational safety

[0013] 9-Sitefacilitiesandlocalstaffcapabilities

[0014] Most pumps are driven by standard AC squirrel-cage motors, however, it may be advantageous to consider asteam or gas turbine for fast pumps, New motor designs, like switched reluctance, are very good for high speedbut require a 'black-box' of electronics. Alternatively, an engine may be better for slow pumps. Steam orcompressed air power supplies can be beneficial in a hazardous area, A submerged pump or a vertical pumpmayprovidethesmallestinstallationfootprint(thatpoorpipingdesigncanhaveanadverseaffect)onperformance, reliability and labor. Piping which is not self-venting and not self-draining may require physicalattentionduringeachstartandstop.Considerthepipingarrangementwhilethinkmgaboutthepumpconfigurati onMuch timeiswastedtroubleshooting'pumps'whenitisthe pipingcausing alltheproblems TechnicalProblemanddeficienciesinthepriorart:

[0015] Improperly operated pumps constitute 12% of pump failures here, fabrication and processing errors cause 8% ofthis plant’s pump failures, faulty design was found responsible for 6% of pump failures, and 4% of the failurepopulation suffered frommatenal defects. Thesestatisticsconveyanumberofveryimportantfacts:

[0016] * Mostpumpsfailbecauseofmaintenanceandinstallation-relateddefects

[0017] • Sincepumps generally represent a mature product, fundamental design defects are relatively rarepumpfailure reductions are largely achieved by appropriate action of plant reliability staff and plant or contractormaintenance work forces. The pump manufacturer rarely deserves to be blamed, although it is unfortunate thatthe pump manufacturer is not always knowledgeable in pump failure avoidance, often, the excessive vibrationcaused bycavitation subsequentlycausesa failureofthepump’s sealand / or bearings.

[0018] 1 - Impellerwearandtear

[0019] As with other failures, there are multiple reasons for impeller wear and tear. One of the most common iserosion,butit canalsoresuit fromanimproperlysizedpump, which canleadtoan imbalance ofpressure.

[0020] Coupling- relatedissuesMostfrequentlyencounteredcouplingfailureshappenforthefollowingreasons:misalignment, overload, uncommonenvironmentalcauses,torsionalvibration andimproperlubri cation.

[0021] 1. Mechanical seal leakage Most leakages usually take place at the interface between the two seal faces, but there are occasions when leakages also come from the secondary sealing area. There are a variety ofreasons for mechanical seal leakage, such as dry running, thermal distortion and misalignment of sealrings, to nameafew.

[0022] 2. Process issues These types of failures happen as a result of an improperly selected pump for the specificprocess, industrial application or operating conditions. So it’s crucial to fit the right pump for yourspecific application.

[0023] 3 Bearing issuesby far the most common reason for bearing failure is improper lubrication (80%), causing it to overheat. Other causes include improper bearing selection, overload, fatigue and manymore.

[0024] A typical example of this problem is when a mechanical seal in a particular pump fails every six months, regardless of the type of seal used in that pump. Maintenance may have tried many different models, types andface material combinations, but the seal fails with the same frequency every time. As it is logical to expectdifferent seals to last different periods of time between failures, it becomes evident that this is a situation wherethesealissimplyactingasthe"fuse"inthesystem. Consequently, theunderlyingproblemisobviously elsewhere in either the pump or the system, Skill and experience come in to play here, the above condition is onewheretheexperiencedtroubleshooterwouldimmediatelyconsidereitherthepumpshaftorthepipingarrangement, dependingon thepumpmodel in question.

[0025] Whatisthenewinthepresentinvention?

[0026] Reciprocation Power Piston pumps RPP are reciprocating pumps consisting of a power end and a liquid end,thepower end of the pump takes the air power and converts the air pressure on movable pistonto reciprocatingmotionor linear motion .

[0027] Thepower source can be a air compressor or, hydrophilic system, whose output must then be converted bymeans of air pressure with direct effect on innermovable piston (2) from up to down continuously , further thismotion controlled by Programmable Logic Controllers PLC , which provide timing of piston movementandpiston speed, onother hand theairvolumecontrolledbysolenoidvalve (22 ).

[0029] With a double-acting Reciprocation Power Piston pumps RPP, liquid is discharged during both the forward andreturn motions of the piston (requiring four check valve (6)for each pistonas a minimum numbers its may bemore). whilebyusingcheckvalve(6)are automaticvalvesthatpreventareturnorreverseflowofthe process.

[0030] The Reciprocation Power Piston pumps RPP can be configured to work as a single acting or doubleactingsystem with two inputs and two outputs, one on the upper and one on the lower side of the pump body. Thisallows for greater flexibility in the system design. Additionally, the pump nozzle can be designed to havedifferent diameters to accommodate specific requirements. Overall, this configuration can enhance the pump'sefficiencyand performancein avarietyof fluid handlingapplications.

[0031] A single-acting Reciprocation Power Piston pumps RPP has liquid discharging only during the forward stork ofthe pistonas mentioned on drawingNo 1 / lloopA.for suction and loop Bfor discharge.

[0032] Double-acting designs are generally associated with control ofslower speeds and medium pressures, or highspeedwithhigh pressurehoweverthecontrolhng as operationneeded. whilesingle-actingdesignsaremoregenerallyassociatedwithhigherspeedsandhigherpressures.

[0033] Whereasthenewinthisinventioncanbechangefromsingleact(loopAandB)todoubleactonsamepumpor can be work as single only (loop A and B ) by using maximum power of pump ,The postilion of a pump canbe adjusted during operations, allowing for vertical or horizontal configurations as needed. This adaptability ensuresgreaterefficiencyandeaseofuseacrossarangeofapplications.Bysimplychangingthepostilion, the pump can be optimized for specific environments or tasks, allowing for maximum output while minimizing theneed for additional equipment. This feature is a valuable one for many businesses, as it allows for greaterflexibilityand versatilityin pumpingoperations.

[0034] Drawing No (1) illustrates that the connection of pipe (10) and (12) can be easily connected to valve set (7), allowing for a smooth transition from a double actuator system to a single actuator system, this accessoryprovidesoperatorswiththeflexibilitytochoosethemostsuitablesystemfortheirneeds theinstallationanduse of thisaccessorycan increaseefficiencyand productivityin variousapplications.

[0035] Pumpsuctioning and discharging various fluids without contamination, they can handle fluids of differentviscosity and densities, making them valuable assets in pumping systems. Pumps provide a reliable means oftransporting fluids from one location to another, such as in industrial processes or transportation of liquids inindustrialsystems, including manufacturing, oil and gas, agriculture, and healthcare. Reciprocation PowerPiston pumps RPP can offer efficient, precise, and consistent fluid transfer, which helps streamline operationsand increaseproductivityfor businesses, largeandsmall.

[0036] By attaching the attachment jet nozzle to valve set (7), it can be used as a jet pump. This process is similar tochangingthenumberofvalvesforsuctionanddischargeforthepurposeofmixing.Theoutputwillbeanagreat additional value of the pumping system. However, it is important to ensure that the nozzle and valve setare compatibleand properlyinstalled toavoid anyaccidents.
