1. Cov kev sib tw tseem ceeb hauv Mini Solenoid Valve Sealing

Lub miniaturization ntawm solenoid li qub qhia txog cov kev sib tw tshwj xeeb rau kev sib khi:

• Qhov chaw txwv: Tight tolerances yuav tsum tau ua raws nraim li cov khoom sib khi.

• High Cycle Demands: Kev kho mob lossis kev lag luam li qub tuaj yeem ua haujlwm ntau lab lub voj voog yam tsis ua haujlwm.

• Tshuaj Compatibility: Cov ntsaws ruaj ruaj yuav tsum tiv thaiv kev degradation los ntawm cov kua qaub (piv txwv li, cov kuab tshuaj, roj).

• Kub siab heevKev ua haujlwm yuav tsum nyob ruaj khov ntawm -40 ° C txog + 150 ° C.

2. Cov khoom siv tshiab rau kev sib khi zoo

A. Elastomer Seals

• FKM (Fluorocarbon): Cov tshuaj tiv thaiv zoo heev rau cov roj thiab roj; Ua haujlwm txog +200 ° C.

• EPDM (Ethylene Propylene Diene Monomer): Zoo tagnrho rau kev siv dej thiab chav dej; resistant rau ozone thiab huab cua.

• Silicone: Yooj yim rau qhov kub thiab txias (-60 ° C) tab sis txwv tsis pub muaj tshuaj lom neeg.

B. Non-Elastomeric Solutions

• PTFE (Polytetrafluoroethylene): Yuav luag chemically inert, nrog kev sib txhuam qis rau cov ntsaws ruaj ruaj.

• PEEK (Polyether Ether Ketone): Siab zog thiab thermal stability rau high-pressure systems.

• Hlau-rau-hlau foob: Stainless hlau los yog titanium interfaces rau ultra-siab nqus / siab daim ntaub ntawv.

Case Study: Lub twj tso kua mis kho mob siv PTFE-coated seals ua tiav xoom xau tshaj 500,000 cycles.

3. Geometric Optimization ntawm Sealing Structures

A. Dynamic Seal Designs

• O-Ring Grooves: Precision-machined grooves xyuas kom zoo compression (20-30% nyem ratio).

• Daim di ncauj: Angled profiles txo kev sib txhuam thaum tuav sealing nyob rau hauv siab reversals.

• Spring-Energized Seals: Siv cov helical springs kom muaj kev sib cuag quab yuam hauv qhov kub thiab txias.

B. Static Seal Solutions

• Pav ca Gaskets: Laser-txiav PTFE los yog graphite nplooj ntawv rau flange sib txuas.

• Conical Rooj: Hlau-rau-elastomer interfaces muab xau-dawb kaw nrog tsawg zog.

Kev pom cov ntaub ntawv: Kev txo qis ntawm 5% hauv kev foob hla ntu txo qis zog ntawm 15%, txhim kho kev ua haujlwm.

4. Cov txheej txheem tsim khoom Advanced

• Pwm Flow Analysis: Optimizes txhaj tshuaj molding tsis muaj qhov tsis xws luag-dawb elastomer seals.

• Nto Finishing: Polishing valve rooj rau Ra <0.2 μm txo qis hnav ntawm cov ntsaws ruaj ruaj.

• Additive Manufacturing: 3D-printed seals nrog gradient hardness rau kev ua tau zoo.

6. Case Study: PinCheng Motor's High-Performance Mini Solenoid Valve

PinCheng Motorua pioneer amini solenoid valveseries nrog ib tug breakthrough sealing qauv:

• Dual-Layer Foob: Ua ke FKM rau tshuaj tiv thaiv thiab PTFE rau kev sib txhuam qis.

• Laser-welded vaj tsev: Tshem tawm cov gaskets, txo txoj kev xau.

• Kev ua haujlwm ntse: PWM tswj minimizes tshav kub tiam, khaws cia ruaj khov.

Cov txiaj ntsig:

• Leak Rate: <0.1 npuas / min nyob rau hauv 10 bar siab.

• Lub neej ntev: 2 lab cycles nyob rau hauv automotive roj systems.
