3 SERIES SELF-SUCTION TYPE NON-CLOGGING SEWAGE PUMP Å ÊöGENERAL A new style produt suessfully developed on the sis of the repeted reserh on the sme know-how of oth t home nd rod. This pump integrtes self-sution nd non-logging nd uses xil-k flow outside-mixing type nd, through the unique design of oth pump sing nd impeller get, needs not to mount foot vlve nd prime the leding wter just like the ommon self-sution pure wter pump nd lso n pump the liquid ontining the solid of ig grins nd long fier impurities. Compred with the sme domesti produts, this pump fetures simple struture, good self-sution performne, strong sewge drining pity, high effiieny, energy sving nd esy use nd repir, with every tehnil performne index of it rnking first ntionlly mong the sewge pump series produts nd up to the world dvned level, nd holds wide pplile mrket nd progressive future. Ó ÓÃ Î RANGE OF APPLICATION 00 PH kg/m % 5 Suitle for the sewge projet in the muniipl works, river quulture, light industry, pper-mking, textile, food, hemil industry, power industry et. nd s the most idel impurity pump to pump fier, pulpy, mixed nd suspended hemil medi. For this pump, the mient temperture, the medium temperture, whih n e up to 00 in se of speil requirement; s of the PH vlue of the medi, st iron 6.9, stinless steel.1; the medium grvity is not over 0kg/m ; the self-sution height is not over the set vlue 4.5-m, the length of suk-in pipe 10m; s of the pssing pity, the suspended grins' dimeter is 60% of the pump perture nd the long fier is 5 times tht of the pump perture. 01

A liquid storing vity is set inside of the pump sing nd onneted to the working vity through the k-flow hole on the upper nd the yling hole on the lower to form the xil-k flow outside mixing type system of the pump. Liquid of ertin volume hs een stored in the storing vity fter the pump stops working nd, under the tion of the impeller when the pump strts, is thrown out upwrds with ir nd then flows k to the working vity through the grids of the ir-liquid seprting pipe, the ir is exhusted out of the pump to hve ertin vuum formed inside of the pump so s to get the self-sution tion. 0

10 ±ÃµÄ ² PUMP INSTALLATION 1 4 A B C With the shfts of oth pump nd motor linked in tution, py ttention to the onentriity etween the pump shft nd the motor's output; nd refully mount nd lirte the pump s whih will leve igger ffetion to the running stility nd durtion of it.. Fsten the nut on the pump's luth, or the impeller my e mde esily movle to use mehnil filure.. Hve the pump inlet higher thn the entrl line of the pump shft so s to hve ertin volume of liquid kept inside of the pump to get etter self-sution pity nd prevent the mehnil sel from drying frition. 4. Cutions for the instlltion of the suk-in pipeline: A. The instlltion height of the suk-in port shll not e higher thn the self-sution height nd shll e lower thn the lowest stored wter level in the wter pool s n s possile, the suk-in pipe shll e s short s possile nd mount less elows so s to shorten the self-sution time nd rise the self-sution funtion. B. The vlve, flnge et. inside of the suk-in pipeline shll e prevented from ir or liquid leking, tht mens no ir-leking is llowed inside of it. C. Get oth suk-in nd vomiting pipelines stnd of their own nd do not let the pump ering ny pipeline. 5. During instlltion of the pump, mke the stti grounding resistne of it nd the pipeline up to the set requirement. 6. Clirte the instlltion spe nd the onentriity etween the luthes of oth pump nd motor, with the llowed devition of the onentriity t 0.1mm, nd put opper or iron sheet under the foot to djust the height differene etween the shfts of oth pump nd motor. 7. Tke finl hek fter the unit tully runs for -4h nd it is deemed for the instlltion to hve een well done if non-d ondition. Chek the ering temperture during tril, whih shll not e over C. 8. If the pump n not e mde to suessfully exhus t during the self-sution proess with single-wy vlve mounted on the pump's outlet pipeline, onnet smll exhusting pipe nd vlve t the pump outlet. 08

11 SERIES SELF-SUCTION TYPE NON-CLOGGING SEWAGE PUMP ±ÃµÄʹÓà USE OF THE PUMP 1 1 ( ) 10 Preprtions nd heks prior to strting 1. Aording to the running sttes, this series self-sution pumps re lurited with qulity lium-sed grese nd 10# engine oil seprtely. For those lurited with grese, fill grese into the ering ox in periodi time nd, for those with engine oil, fill it fully when the oil level is insuffiient.. Chek if the stored liquid inside of the pump sing is ove the upper edge of the impeller nd, if not, prime liquid diretly from the filling port on the sing. Do not strt the pump in se of n insuffiient stored liquid, or the pump would not work normlly nd the mehnil sel would e esily dmged.. Chek if the moving prts of the pump re jmmed or ollided; if the foot on the pump ottom nd the nuts on the joints re loose; hek the onentriity or the prllelism etween the shfts of oth pump nd motor; hek if there is ir-leking with the inlet pipeline nd settle it if ny; open the vlve on the suk-in pipeline nd slightly open (not fully) the outlet ontrol vlve. Strt nd opertion 1. Py ttention to the pump shft to see if it moves in the orret diretion when to strt the self-sution pump; nd if there is norml sounds nd virtion when it moves.. Py ttention to the redings on oth pressure guge nd vuum meter, when the inditions of whih get stle fter periodi time flutution fter the pump is strted, tht mens liquid hs een primed into the pump nd the pump gets into the norml liquid trnsporttion. Before the pump gets into the norml liquid trnsporttion, e.g. during the self-sution proess, py speil ttention to the temperture rise of the liquid nd stop the pump to hek the use if this proess is too long nd the temperture is so used too high.. Temporrily stop the pump in se of diffiult selfsution used due to too high liquid temperture nd mke it lower y mens of the k flow into the pump of the liquid in the vomiting pip eline or supplementing liquid diretly from the filling port on the pump sing, then strt the pump gin. 09

12 4 5 1 ( ) 4. It is possile for n ir erosion to our with the pump tht uses severe virtion nd noise during the work of the pump nd the ir erosion ours with two uses: one is too quik flow rte in the inlet pipe nd the other is too high sution trvel. For the former, djust the outlet ontrol vlve, rise the reding on the pressure guge nd remove it in se of lokup in the inlet pipeline; for the ltter, properly lower the pump's instlltion height. 5. When the pump is stopped euse of something during work nd strted gin, slightly (not fully) open the outlet ontrol vlve. This is enefit for the ir to e exhusted on-time from the vomiting port during the self-sution proess nd lso ensures the pump is strted with lighter lod. Menwhile, py ttention to heking if there is lek from the pipeline system. Stop 1. First lose the vlve on the vomiting pipeline.. Hve the pump stopped running.. In old sesons, drin out the liquid stored inside of the pump sing nd the wter inside of the ering's ooling hmer ompletely to prevent ny prts from eing frozen to rk. 10

Trouleshoot it in se of filure. Cutions t mintenne When the rolling ering nd oth front nd rer sel rings re worn out to ertin degree fter long time running of the pump, reple them; the mehnil sel does not need to e removed for hek provided tht no liquid lek with it while does when there is serious lek from the leking port on the lower side of the ering. Tke re of the mehnil sel during disssemly nd ssemly, len the fitted fe, properly keep the mirrors of oth stti nd dynmi rings nd do not knok on them nd get them ollided, s the use for the leking of it is minly t the urrs on the fritionl pir mirrors. To repir it, grind the mirrors to hve it reovered. Another use for the mehnil sel to lek is the O -type ruer sel ring (or uffering gsket) improperly mounted or deformed or ged, then djust or reple it. Pump disssemly nd ssemly sequenes A. Remove the motor or tke out the luth. B. Remove the ering ssemly, hek the rdil spe etween the impeller nd the front orl ring nd hek if the impeller nut is loose. C. Srew out the impeller nut, pull out the impeller nd hek the rdil spe etween the impeller nd the rer sel ring. D. Loosen the fixing srew on the mehnil sel, pull out the dynmi ring nd hek the fitting stte etween the end-fes of oth stti nd dynmi rings nd the seling stte of the O -type sel ring (or the uffering gsket). E. Srew out the fixing nut on the luth nd pull out the luth. F. Remove the end over on the ering to remove oth pump shft nd ering. G. Tke reversed sequenes for ssemly. 11
