Lub zog kawg- lub plawv tsis muaj zog

Muaj zog welded steel ncej: tsis zoo li cov tsoos cam khwb cia hlau thav duab, WH-440 lub zog thav duab yog welded nrog siab -lub zog qis-alloy steel thiab kub kho tom qab vuam.

Ib qho -daim forged crankshaft: peb tsis lees txais ntau- ntu ntsia liaj qhov rooj- ntawm kev tsim qauv uas ua rau muaj kev ntxhov siab thiab siv ib qho - daim forged thiab precision machined crankshaft ua los ntawm cov hlau alloy sab saum toj (hloov 4340).

Precision Herringbone Iav: lub hauv paus ntawm lub tshuab tsav yog lub forged alloy steel iav tsim nrog herringbone (ob chav helical) cov hniav. Qhov kev tsim no ua rau lub zog xa hluav taws xob ntau dua thiab ntsiag to, tshem tawm qhov cuam tshuam ntawm kev thauj khoom, thiab nws qhov kev tsim khoom raug ua tau raws li lossis tseem tshaj AGMA qib 11 tus qauv.

Tag nrho cov menyuam bearing tsim: zoo tiv thaiv-cov menyuam bearings yog siv thoob plaws hauv lub hwj chim kawg, es tsis txhob ntawm cov tsoos zawv zawg bearing, kom ua tiav qhov kev sib txhuam qis tshaj plaws thiab lub neej ua haujlwm ntev tshaj plaws.

Rov qab tsis tu ncua lubrication system: txhawm rau txhawm rau daws qhov teeb meem ntawm lubrication tsis txaus, WH-440 yog nruab nrog kev sib xyaw ua ke ntawm kev quab yuam lubrication thiab txaws lubrication system. Qee qhov kev teeb tsa high-end muab cov roj twj tso kua mis sab nraud uas tau tsav los ntawm kev ywj pheej motors, triple redundant tiv thaiv kom muaj lubrication txaus ntawm tag nrho cov khoom tseem ceeb ntawm txhua qhov ceev.

Hydraulic kawg- tswj lub siab kawg

L-zoo li tus forged alloy steel qauv: peb txais kev lag luam- lees paub L- zoo li hydraulic kawg module tsim, uas yog ua los ntawm sab saum toj- qib forged alloy steel, xws li 35CRMO lossis 40CrMnMo. Cov txheej txheem forging ua ke nrog kev kho cua sov kom nruj thiab tsis yog -kev kuaj kev puas tsuaj (NDT) kom ntseeg tau tias cov qauv tuaj yeem tiv taus kev ua haujlwm siab txog li 5,000 PSI thiab txawm tias 7,500 PSI nrog kev qaug zog tshwj xeeb thiab corrosion kuj.

API standard Valve Assembly: WH-440 siv Kev Lag Luam Standard API # 4 valve los ua ke kom ntseeg tau tias muaj ntau yam ntawm cov khoom seem. Lub cev lub cev thiab lub rooj zaum yog forged los ntawm cov hlau zoo zoo xws li AISI 4119 lossis 20CrMnTi thiab raug rau kev sib sib zog nqus carburizing kub kho nrog nto hardness mus txog HRC Ntau tshaj lossis sib npaug rau 60, muab qhov kawg hnav tsis kam thaum tuav lub toughness ntawm cov tub ntxhais los tiv thaiv kev cuam tshuam.

Kev ua haujlwm siab fittings thiab cov khoom siv technology

Peb muab ntau yam ntawm cov khoom hnav ua los ntawm sab saum toj - ntawm - cov ntaub ntawv kab thiab cov cuab yeej siv siab heev uas tso cai rau koj los kho lub twj tso kua mis rau kev ua haujlwm tshwj xeeb kom ua kom lub sijhawm khiav thiab txo cov nqi tu.

Khoom siv	Cov ntaub ntawv thiab cov txheej txheem	Core Strengths
Liners	High chromium bimetal: forged steel rooj + centrifugally cam khwb cia siab chromium (CR> 27%) hauv ob sab phlu, sab hauv phab ntsa hardness HRC 60-69. Zirconia ceramic: forged steel plhaub + zirconia (Zro3) ceramic hauv ob sab phlu, sab hauv phab ntsa hardness HRC> 90.	High chromium: zoo heev hnav tsis kam, tus nqi -zoo, haum rau feem ntau drilling tej yam kev mob, lub neej> 800 teev. Ceramics: the ultimate wear and corrosion resistance, ultra-long life (>4000 teev), txo qis piston hnav, yog qhov kev xaiv zoo tshaj plaws rau huab cua.
Pistons	Piston Core: 45 # steel lossis 40CR forged, kho cua sov. Piston roj hmab: cov mis tshwj xeeb ntawm polyurethane lossis nitrile roj hmab (NBR), siv cov nplaum tsim.	Roj kuj, kub tsis kam, hnav tsis kam, extrusion kuj. Kev ruaj khov thiab txhim khu kev qha hauv cov roj-raws li thiab dej-raws li av nkos nrog kev ua haujlwm siab tshaj plaws txog 280℃F.
Piston Rods	Siab zog alloy steel (xws li . 42CrMo), forged, tshav kub kho thiab precision av. Hard chromium plating yog xaiv tau los txhim kho corrosion kuj.	Tsis tshua muaj siab tensile lub zog thiab qaug zog tiv thaiv kom ruaj khov zog hloov mus rau hauv siab.
