Pogo pins yog cov khoom siv hluav taws xob zoo nrog lub caij nplooj ntoos hlav sab hauv, tsim los tsim kev ruaj khov, ib ntus hluav taws xob sib txuas ntawm ob lub voj voog. Lawv tau siv dav hauv cov neeg siv khoom siv hluav taws xob, tsheb, kev kho mob, aerospace, thiab cov khoom siv kuaj vim lawv cov kev ntseeg siab, miniaturization, thiab durability.
Core Structure & Txoj Cai Ua Haujlwm
Tus qauv pogo tus pin muaj peb qhov tseeb - cov khoom siv tshuab:
Plunger (Needle):Sab saum toj tiv tauj, feem ntau yog kub -plated beryllium tooj liab lossis tooj dag. Cov duab ntau: puag ncig, taw tes, concave, los yog riam-ntug.
Caij nplooj ntoos hlav:Ua los ntawm stainless hlau (SUS304 / SUS316) los yog suab paj nruag hlau, muab cov axial quab yuam (feem ntau 50-200gf).
Tube (hli):Lub vaj tsev sab nrauv uas kaw lub plunger thiab lub caij nplooj ntoos hlav, kuj kub -plated rau qhov tsis muaj zog.
Nws ua haujlwm li cas:Thaum nias, lub plunger compresses lub caij nplooj ntoos hlav thiab swb rau hauv lub thoob. Cov kub- plated nto tuav cov hluav taws xob sib txuas. Thaum lub siab tso tawm, lub caij nplooj ntoos hlav rov qab lub plunger mus rau nws qhov chaw qub. Kev tsim oblique ntawm lub plunger lub hauv paus ua kom muaj kev sib cuag nrog lub thoob, txo qis kev tiv thaiv thiab tsis txhob ntws tam sim no los ntawm lub caij nplooj ntoos hlav.
