Technical GuidesMaintenance GuideMaintenance GuideImpact SprinklersImpact Sprinkler Head Types:Spoon-Driven, Wedge-Driven,and Precision Jet (PJ ).Principal of OperationOn spoon-driven sprinklers, (Figure 1) thewater passes through the body (1), thenthrough the nozzle (2), past the sloping vane (3),through the window (4) into the curve of thespoon (5). The reactionary force of the waterleaving the spoon drives the arm out of thestream and away from the nozzle. The tensionof the arm spring (6) then pulls the arm backinto the original position where it impacts onthe bridge or nozzle, causing the sprinkler to turn. The impact is accentuated by thethickness and angle of the leading edge of the sloping vane.This impact is only sufficient to cause a small degree of travel so that the rotation ofsprinkler is uniform and relatively slow (one-half to three minutes per revolution,depending on pressure and size of sprinkler and nozzle). Slow rotation keeps wear onmoving parts at a minimum and prolongs the life of the sprinkler.Wedge-drive sprinklers (such as the Rain Bird 14V) operate in the same manner exceptthat the wedge rather than a spoon serves to force the arm in or out of the water stream.The chief advantages of the wedge are that it prevents an excessive amount of waterfrom being deposited just below the sprinkler, and that it provides a greater driving forcethat rotates these sprinklers satisfactorily with smaller size nozzles.How Impact Sprinklers OperateRain Bird patented Precision Jet (PJ )sprinklers operate in a manner similarto a spoon-drive sprinkler with the PJtube replacing the spoon. When thearm enters the stream, the water isdirected through a tube. The back forceof the water exiting the tube is along aline away from the fulcrum and,therefore, the arm is kicked back out ofthe stream. The advantage of theprecision jet sprinkler is that side splashis eliminated. The PJ feature is used onpart circle sprinklers that are placedadjacent to areas not to be watered.1 Foreign Objects in Irrigation WaterIf the sprinkler does not contain a streamstraightener (small vaned device inside sprinkler inthe nozzle, or just behind nozzle), soft materialsmay be removed from obstructed nozzles byinserting a coated or covered piece of wire, such asa pipe cleaner, through the nozzle while thesprinkler is operating. Care should be taken to avoidscratching the nozzle opening. If this fails, thenozzle should be removed and cleaned. Sprinklerscontaining stream straighteners should not becleaned with a wire because of the possibility ofdamaging the vanes on the straightener. It isrecommended that the nozzle and straightener beremoved and cleaned.The best guarantee against nozzle pluggingproblems is to adequately screen the water where itenters the system. Where water is derived fromirrigation ditches, screening at the intake is anecessity. Information on types ofscreening/filtering devices may be obtained fromyour Rain Bird distributor.Cause of Sprinkler Failure orFaulty OperationFIGURE 1www.rainbird.com/agThrough many years of experience, wehave found the conditions whichinterfere with the proper operation ofRain Bird sprinklers. The following itemsoutline these conditions in detail andprovide the necessary steps to resumeproper sprinkler operationPage 1
Technical GuidesMaintenance Guide2 Oil or Pipe DopeRain Bird sprinklers are WATER LUBRICATED and must NOT be oiled in any manner. Oilcauses the bearing washer to swell and soften and affects the rotation of the sprinkler,frequently bringing it to a complete stop. Pipe dope or thread lubricant contains oil, andwhen applied to the bearing threads is carried to the washer, saturating it and causingthe sprinkler to stop turning. If oil has been applied to the sprinkler, it will be necessary todisassemble the bearing and wipe the oil off the sleeve and nipple and replace thewasher(s) with a new, clean one.AdjustingScrew & SpringBearing washers are composed of material which provides the friction necessary for thesuccessful operation of the sprinkler. As stated previously, Rain Bird sprinklers are WATERLUBRICATED and all materials used in their construction are anti-rust and anti-frictionmetals, except the bearing washer.NozzleADJ NOZZLE3 Improper PressureRain Bird sprinklers are designed and adjusted to operate over fairly wide pressureranges depending on the model. When operating on pressure that is either too high ortoo low, the performance will be unsatisfactory both as to sprinkler rotation and waterdistribution. Operating a nozzle at too low of a pressure will result in large droplets and adistribution of most of the water around the outer edge of the pattern. If the pressure isextremely low the sprinkler may fail to rotate. In the case of too high a pressure, thenozzle will tend toward misting and even slight wind currents will carry the water awayfrom the desired pattern. Extremelyhigh pressure could cause theFIGURE 2sprinkler arm to strike the back ofPitot Tube - 41017the sprinkler body, causing theand Gauge - RBGL 100sprinkler to stand still or turnbackwards. In general, as nozzle sizeincreases, so must the pressure fordesired performance.4 Measuring Water PressureThe nozzle pressure of a sprinkler ismeasured with a pilot tube while thesprinkler is in operation.The pitot tube is used with apressure gauge a shown in Figure 2.When used to measure theoperating pressure of a sprinkler,where more than one sprinkler isoperating on one pipe line or lateral,the curved end the tube is insertedinto the stream 1/16" from nozzle.When measuring the operatingpressure the curve end of the tubemust be held approximately 1/16”out from the nozzle opening and inthe center of the stream. (Figure 3)This is done so that the flow of waterfrom the individual sprinkler will not be retarded, thus building up the pressure.Move the curve end of the tube back and forth through the stream until the highestpressure is recorded. Do not insert the pitot into the orifice.NozzleDeflectorDC NOZZLEFIGURE 4advisable to use a nozzle smaller than the minimumrecommended size for the particular sprinkler model.To illustrate, sprinkler Model No. 30W failing tooperate properly with a 3/ 64 ” nozzle may give verysatisfactory performance with a 9/64” nozzle.On the ADJ models, an adjustable pin is used on thenozzle extension- see Figure 4. At pressures from 30pounds up, the pin should not be set into the streamas far as when the sprinkler is operating at lowerpressures (20 to 30 pounds). For these low pressures,you can adjust the pin so as to secure the desiredbreak-up of the stream. This pin also can be adjustedto shorten the throw of the stream, where it isdesirable to use the sprinkler in a smaller area.The DC nozzle is used for controlling distance ofthrow. It is operated by adjusting the deflectordownward into the water stream to decrease thedistance of throw as desired.FIGURE 3Pilot tube shown properly inserted into sprinkler nozzle.(Approx. 1/8" from nozzle opening)Spring HolesStreamAll pressures indicated in this manual and our catalog are pressures at the sprinkler,which may differ considerably from pressures at a distant source from which water issupplied. Small diameter pipe or hose will reduce pressure considerably. Failure of asprinkler to perform properly when pressure is lower than recommended for a particularsize nozzle may be overcome by changing to a smaller size nozzle. However, it is notNozzleSection A-AFIGURE 5Page 2
Technical GuidesMaintenance Guide5 Damaged PartsBend EndsInside ArmsOccasionally sprinkler parts may be bent byaccident. Cast bronze and aluminum alloy, usedin Rain Bird parts, are pliable to certain limits.These parts can usually be bent back into shapeif they are not too badly damaged.In the case of bending of a model 20 or 25 arminto shape after it has been damaged, it shouldbe done so the vane “x” fits flat on the nozzlesurface and so the stream will enter the window“y” as show in Figure 5.If possible, water test sprinkler. Bring pressure upslowly to ensure that arm does not stick in stream.Also, try to hold arm in stream to see if it will comeout and oscillate of it’s own accord.7 Worn Bearing WasherSpoon Endof ArmFIGURE 7A good rule of thumb for adjusting a bent arm is to bend it so that when the arm is atrest, the vane “x” (Figure 5) is just to the left of the nozzle opening when viewed towardthe nozzle face with the sprinkler in an upright position.Inspect bearing washer (normally black),periodically and replace if worn or damaged. Failureto make needed replacements of these parts willresult in damage to the more expensive BearingNipple and Sleeve.H Style BearingTop Seal WasherStainless SteelWasher6 Broken Arm SpringPry DownFIGURE 6To replace arm spring, pull the fulcrum pinwith a pair of large diagonals or sidecutting pliers as show in Figure 6. The pinis pressed into the body and will come outwhen pulled as show in sketch. Cut thespring loose and remove parts.Bearing SpringArm weights for some sprinkler mo els are available from Rain Bird distributors anddealers in order to adjust for proper spring tension. To check spring tension with the armweight, hang the weight over the outer lip of the spoon, with the sprinkler held in asideways position. The weight should deflect the leading edge of the spoon below thenozzle opening but not beyond the hex point on the outside of the nozzle. If an armweight is not available check the arm tension with that of a new sprinkler or with onethat is operating satisfactorily.Bearing WashersWear WasherFeed end of spring through the holes inthe arm, as shown in Figure 7, in thefollowing way.Holding the arm in your hand with the cup part of the spoon facing you, and spoon endof arm pointed to your right, feed end of springinto hole on your right (hole nearest spoon) thenUse of Arm Weighton through the hole on the left from the backside. The end of the spring is now pointingtoward you. Bend over end (approximately 1/4”)using needle nose pliers (see Figure 7). Thespring wire is normally longer than required.Hold arm with spoon end pointing toward you(looking down on top of arm). Cut off the tag endof the spring at the center line of the arm. Nowinstall arm in body as shown in Figure 7. Drivefulcrum pin into lower hole with hammer. PullFIGURE 8arm around as far back as it will go, away fromnozzle and feed upper end of spring into thehole that is farthest from the nozzle. Then feed through the other hole so it extendsabout 1/8” and bend this extended spring end over sharply to clinch. Check theassembled spring to be sure that the spring end does not rub against the center bearingof the arm or the spring coils when it rotates (see Figure 7).Bearing SleeveBearing NippleFIGURE 98 Worn Wear WashersThe Bearing Sleeve is threaded on the lower end forattachment of the sprinkler to the piping system.The bottom of the lower end of a TNT style bearing(see Figure 10) is machined in such a shape as to fita T-shaped wear washer. Because of this fit the wearwasher should not turn in the Sleeve recess. Thebottom of the lower end of the Sleeve is a seat only,FIGURE 10TNT Style BearingWear WasherBearing WasherFIGURE 11Universal BearingWrenchwww.rainbird.com/agPage 3
Technical GuidesMaintenance Guidenot a wearing surface, which is also true for theSleeve in the H style bearing. Note that the Hstyle wear washer is flat and is locateddifferently than the water washer for the TNTstyle bearing (see Figure 9).Check the wear washer periodically and replaceif worn or damaged. Failure to replace willdamage the much more expensive BearingNipple and Sleeve.9 Replacing Bearings11 Setting Part Circle Friction CollarsFIGURE 12Bearing WasherTrip WashersA special wrench (Figure 11) is made to fit allE-RingBearing Nipples and to unscrew them from thebody. This wrench should be available at yourRain Bird dealer; however, if you can not secureone, a small bar or large screwdriver may beused to unscrew the bearing. Be cautious whenplacing the sprinkler in a vise, not to squeeze the arm or other extended parts use thebody. Washers that are worn thin from sand and other abrasives in the water should bereplaced.10 Trip Mechanism on Part Circle ModelsThe purpose of the friction collars is to control thearc of the circle of coverage. On the 25, 35, and 65D,the collars must be moved with the fingers only.Never use pliers in setting these collars. Use of plierswill cause the collars to lose their tension and, aftera few settings, they will no longer hold theirposition.SPRINKLER REPAIR SERVICEIf, after following the directions in this manual, yourRain Bird sprinkler does not operate properly, take itto your dealer or distributor for servicing. If they donot have the facilities for necessary repairs, contactthe factory for the nearest authorized servicingfacility.DO NOT USEOIL GREASE PIPE DOPERAIN BIRD SPRINKLERS ARE WATER LUBRICATEDModel No. 25Sand-Cast Trip Models-Bronze ColorThe trip spring (Figure 12) is about the only item in this assembly that may need to bereplaced after extended use. To reach this spring, pull off the whole assembly after firstremoving clip. Cut the spring loose from the upper trip casting and replace with a newone in the same position.After bending the spring, be sure there is not too much wire left. If there is, cut the endoff so that it won’t rub against the lower trip casting. The assembly must be put togetherbefore it goes on the shaft.Be sure spacer washers are in place as shown in Figure 12. Some water causes limedeposits, which should be cleaned off. Lime deposits can cause the mechanism to stickafter a few years use.Model No. 25Powered Metal trip Models-Yellow ColorRemoving and replacing the trip spring for these sprinklers is the same in every respectas for sand cast trip models expect that the spring is held in place by a preform on oneleg of the spring. No bending and cutting of the wire is required. The new spring isinstalled by pressing the spring leg with the preform through the appropriate hole andthen following the above instructions for the sand-cast trip models.Models No. 35 and No. 65DAlthough somewhat different in their parts, the operation of these models is basically thesame as the No. 25.Page 4
