Dab tsi yog cov khoom siv zoo tshaj plaws rau Piston Rods?

Piston rods-cov khoom tseem ceeb hauv hydraulic thiab pneumatic thooj voos kheej kheej- yuav tsum tiv taus kev ntxhov siab, kev thauj khoom cyclic, hnav nto, thiab feem ntau corrosive ib puag ncig. Xaiv cov khoom tsim nyog yog qhov tseem ceeb rau kev ua haujlwm ntev, kev sib khi ua haujlwm, thiab kev cia siab rau lub cev. Thaum siv ntau cov ntaub ntawv, hardened thiab av alloy steel yog dav suav hais tias yog qhov zoo tshaj plaws tag nrho cov kev xaiv rau feem ntau cov ntawv thov kev lag luam.

1. Hardened & Ground Alloy Steel (xws li AISI 4140, 4340, los yog EN 25CrMo4)

✅ Feem ntau & Pom zoo

- Vim li cas nws thiaj li zoo:

- Lub zog tensile siab (Ntau dua lossis sib npaug ntawm 900 MPa) thiab qaug zog ua haujlwm;

- Nto hardness ntawm HRC 50-60 tom qab induction hardening los yog nitriding, kom ntseeg tau zoo heev hnav tsis kam;

- Precision- hauv av tiav (Ra Tsawg dua lossis sib npaug li 0.2 μm) ua kom muaj kev sib txuas zoo meej thiab xau tsawg;

- Zoo toughness los tiv thaiv dabtsi yog khoov lossis poob siab loads.

- Siv ib txwm: Cov tshuab hnyav, cov khoom siv tsim kho, cov khoom siv hydraulic.

>Feem ntau chrome-plated rau ntxiv corrosion kuj (saib hauv qab).

2. Stainless hlau (xws li AISI 304, 316, lossis 17-4PH)

✅ Qhov zoo tshaj plaws rau Corrosive lossis huv ib puag ncig

- Qhov zoo:

- Kev xeb thiab tshuaj lom neeg zoo heev- zoo tagnrho rau kev ua zaub mov, dej hiav txwv, lossis cov nroj tsuag tshuaj;

- 17-4PH muaj lub zog siab (HRC 30–45) nrog corrosion kuj zoo.

- Kev txwv:

- softer dua hardened alloy steel → ntau dua rau cov qhab nia;

- Tus nqi siab dua;

- Tsis zoo rau siab -load lossis siab- hnav daim ntawv thov tshwj tsis yog nag lossis daus- tawv.

3. Induction-Hardened Carbon Steel (piv txwv li, SAE 1045)

✅ Nqis -Zoo rau nruab nrab-Kev siv lub luag haujlwm

- Zoo sib npaug ntawm lub zog thiab machinability;

- Nto hardness mus txog HRC 55 tom qab induction hardening;

- Feem ntau siv rau hauv kev ua liaj ua teb lossis lub teeb muaj lub tog raj kheej.

4. Chrome-Plated Rods (feem ntau dhau Alloy Steel)

✅ Txhim khu kev ua tau zoo Standard

- Feem ntau siab tshaj -piston pas nrig muaj qhov nyuaj chrome plating txheej (20-50 μm tuab) tshaj cov hlau tawv:

- Txo kev sib txhuam thiab txhim kho lub neej foob;

- Muab kev tiv thaiv corrosion zoo heev hauv qhov chaw me me;

- Tsim ib daim iav-zoo li nto (Ra 0.05–0.2 μm).

- Nco tseg: Chrome plating yog kev kho saum npoo, tsis yog cov khoom siv hauv paus.

>⚠️ Hauv cov chaw muaj corrosive heev (xws li, dej ntsev), xav txog nickel- chrome plating lossis stainless hlau hloov, vim micro- tawg hauv chrome tuaj yeem ua rau pitting.

5. Kev Xaiv Qhov Tseem Ceeb:

Rau feem ntau cov tshuab hydraulic, induction-hardened lossis nitrided alloy steel (xws li 4140) nrog qhov tseeb- hauv av thiab chrome- plated nto muab qhov zoo tshaj plaws tshuav ntawm lub zog, hnav tsis kam, smoothness, thiab nqi. Nyob rau hauv corrosive los yog huv daim ntaub ntawv, stainless hlau variants coj ua ntej. Ib txwm phim cov khoom siv pas nrig rau koj qhov chaw ua haujlwm, kev xav tau siab, thiab kev cia siab rau lub neej kom ntseeg tau qhov siab tshaj plaws lub tog raj kheej kev ua haujlwm thiab kev ua haujlwm ntev.
