	(5) Uhlanga lokuvuza komoya noma ukuvulwa epayipini lokufaka uwoyela	(5) Faka i-grease ukuze uhlole. Uma umsindo uncipha, kukhombisa ukuthi ipayipi liyavuza. Shintsha i-seal noma ipayipi
	(6) Tanki ha na mafuta ya kutosha	(6) Faka ngokuhambisana nezidingo zethangi likawoyela
	(7) Ukulinganiselwa okungafaneleko kwepipa, ivali noma isixhumi sepipe	(7) Ukuphuculwa emva kokulinganisa ngokweziqondiso
	(8) Iphayiphu yokufaka uwoyela ende kakhulu kanye nezikhonkwane eziningi	(8) I-ubude yephayiphu yokufaka uwoyela kufanele ingabi ngaphezulu kuka-2.5m futhi inani le-elbows akufanele lidlule ku-2
	(9) I-coaxiality ye-pump kunye ne-prime mover iphume ngaphandle kwemida	(9) Ngemuva kokupaka, ukuxhumana kufanele kube lula ukuphatha futhi kube nekhala le-axial, kungenjalo, i-coaxiality kufanele ilungiswe ukuze kususwe ukuphazamiseka
	(10) Ukusetha okungafaneleka kwengcindezi ye-relief valve noma ukuvuza okweqile ku-valve nase-actuator	(10) Ukuba ukuvuza kwi silinda kukhulu kakhulu, umgibeli wepiston uya kuqhwatywa
	(11) Qala ngaphambi kokuvula ivali ye-oyili	(11) Iphampu igugile futhi idinga ukulungiswa
	(12) Ivalvu ye-electromagnetic yokuhambisa ayishintshi umkhondo	(12) Hlahla
	(13) I-oyili viscosity iphezulu kakhulu noma i-oyili temperature iphansi kakhulu	(13) Guqula uwoyela enezinga eliphansi lokuphuma noma ufudumele ithangi le-oyela

	(16) Kukhona uthuli phakathi kwevalve plate nomzimba wepomp, noma i-positioning pin yevalve plate ayifakiwe kahle, ukuze i-valve plate nomzimba wesilinda zingahambisani kahle	(16) Disassemble the pump, clean the moving parts and reassemble
	(17) Iphutha le-angle yokuphenduka komshini oshintshashintshayo lincane kakhulu, ngakho-ke ukuhamba kuncane kakhulu, i-relief valve ayikwazi ukusungula ingcindezi noma ayilungiswanga kahle	(17) Yongeza i-deflection angle ye-variable mechanism ukuze wandise ukuhamba, hlola ukuba ingxube ye-damping ye-relief valve ivaliwe na kunye nokuba i-pilot valve igudile na, kwaye uphinde ulungise i-relief valve
	(18) I-leakage yezinye izingxenye ohlelweni inkulu kakhulu	(18) Ukushintshwa kwezinto ezihlobene
	(19) Iphampu yokuhlinzeka ngengcindezi yokuhlinzeka ngengcindezi ayikwazi ukufinyelela ingcindezi edingekayo ohlelweni lwe-hydraulic ① Imecha ye-variable ayilungiselelwanga kumphumela wamandla ofunwayo ② Khi nhiệt độ tăng, áp suất yêu cầu không đạt được	(19) Hlola futhi ulungise ① Faka umphumela wezici eziguquguqukayo zephampu ② Kwehlisa ubushushu besistimu noma ushintshe izingxenye ezine-leakage ey excessive ngenxa yokwenyuka kobushushu
External leakage	(1) Ukuguga kwesikhwama sokuvikela	(1) Hlanza futhi uhlole ingxenye yokuvikela, hlola ingxenye ebhujiswe ye-O-ring phase skeleton oil seal kanye ne-scratch, bump, burr, njll. yephuzu elihambisanayo ngokuningiliziwe, bese uyigaya kahle, bese uyifaka ngempela ne-sealing ring entsha
External leakage	(2) Ukuphuma kokuphuma emgqeni we-oil seal we-shaft end framework ① Ukugqoka kwefreyimu ye-oil seal ② Ukugqoka kwe-shaft yokudlulisa ③ Ibhakede ye-oyili engxenyeni ephansi ye-0.05Mpa. Ukuvikelwa kweframu kulimele. ④ I-diameter ye-external drain pipe incane kakhulu noma i-pipe ibanzi kakhulu	(2) Ukuphula nokuhlola ① Faka i-framweki ye-oli seal ② Slight wear can be corrected with metallographic sandpaper and oilstone, and serious eccentric wear should be returned to the manufacturer for replacement ③ Hlanza i-oil drain port, lungisa ama-pair amabili e-moving oil, shintsha i-framework oil seal, sebenzisa amathuluzi akhethekile ngesikhathi sokuhlanganisa, futhi i-lip kufanele ibe ngase-pressure oil side ukuze kuqinisekiswe ukuvikelwa. ④ Faka i-pipe yokukhuculula efanele
Excessive vibration and noise	(1) Pump ayikho noma ayigcwalisiwe	(1) Faka amanzi

	(3) I-viscosity ye-oyili iphezulu kakhulu, kanti i-oyili temperature iphansi kunomkhawulo wokusebenza ovumelekile	(3) Sisa mafuta afane ne tembiricha yebasa kana kupisa injini pakukurumidza kwepasi pamberi pekutanga
	(4) Amanzi emoyeni noma ahlanganiswe nezinto ezingcolile (uwoyela omubi mnyama)	(4) Shandura iyo fluid
	(5) Iphikha ye-oyile yokumunca ibhadiwe kakhulu, isihlungi sithole ukuvinjwa okuthile, ipayipi lide kakhulu, futhi kunezikhala eziningi.	(5) Phumula umphumela wokuphikisa emgwaqweni wokuthatha uwoyela
	(6) Umoya ophumayo emgqonyeni wokuthola uwoyela	(6) Faka i-grease endaweni yokuhlangana ukuze uhlole futhi uqedele ukuvuza komoya
	(7) Uhlanga lomoya lwezinhlelo ze-hydraulic (iphampu yokubuyisela ayifakiwe ngaphansi kwezinga lamanzi)	(7) Insert all return pipes 200 mm below the oil level
	(8) Pump na prime mover coaxiality pharanya, oba shaft interference na coupling loose vibration	(8) Re adjust the coaxiality (no more than + 0.05mm) I. after parking, the manual coupling should be easy to handle
	(9) I mafuta ari mu tanki yemafuta haakwanisi kana kuti pombi yekudonhedza mafuta haina kupinze pasi pemwero wemvura	(9) Phakamisa uwoyela ethangini leoyela ukuze wenze izinga leli liquid lingaphakathi komkhawulo okukhulunywe ngawo, bese ufaka ipayipi lokukhipha ngaphansi kwezinga leli liquid
	(10) Iphayiphu ayihambisani nosayizi ophakanyisiwe wepipa, ivali noma isixhumi sepipe	(10) Phayipha ngokuhambisana nosayizi ophakanyisiwe wephayiphu noma wephayiphu oxhunywayo
	(11) Ibhokisi lomoya noma ifilitha yomoya ethangini le-oyela ivaliwe	(11) Hlanza umoya ophumayo noma ifilitha yomoya ethangini le-oyili
	(12) Isistimu yephayiphu yokudlidliza	(12) Beka pipe clamp ku dikhisa vibration
	（13）If the noise of the pump suddenly increases during normal use, it must be shut down. The reason is mostly due to the loosening of the plunger and sliding shoe rolling ball hinge, or damage to the internal parts of the pump.	（13）By the manufacturer for maintenance, or disassembled and repaired by experienced technicians
异常发热	（1）油液黏度不当	（1）Change oil
	（2）Oil tank capacity too small	（2）Increase the fuel tank area, or add cooling devices
	（3）pump noma hydraulic system leak loss too big	（3）Jianxiu youguan yuancian
	（4）油箱油温不高，但泵发热 ①Pump long-term operation at zero offset angle or low pressure, resulting in minimal pump leakage. ②漏损过大使泵发热 ③Ukuxhumana okungafaneleki, ukukhetha okungafaneleki kwe-gaps	（4）Take the following measures ①在液压系统阀门的回油管上分流一根支管通人泵下部的放油口内，使泵体产生循环冷却 ②Ukulungisa i-pump ye-oyile ③按照装配工艺进行装配，测量间隙重新配研，达到规定合理间隙
泵油管回油太多	配油盘和缸体、变量头和滑靴两对远动副磨损	更换这两对运动副
