katrangan

Piston minangka bagean bolak-balik ing blok silinder mesin.Struktur dhasar piston bisa dipérang dadi ndhuwur, sirah lan rok.Ndhuwur piston minangka bagean utama saka kamar pembakaran, lan wangune ana hubungane karo wangun kamar pembakaran sing dipilih.Asring ana macem-macem pit ing ndhuwur piston mesin diesel, lan wangun tartamtu, lokasi lan ukuran kudu dicocogake kanggo syarat saka formasi lan pangobongan campuran engine diesel.
Fungsi utama piston yaiku kanggo nahan tekanan pembakaran ing silinder, sing dikirim menyang crankshaft liwat pin piston lan piston.Banjur, piston, sirah silinder, lan tembok silinder mbentuk ruang bakar.
Dering piston duwe perawatan permukaan sing beda amarga posisi sing beda.Lumahing njaba ring piston pisanan biasane dilapisi krom utawa disemprotake karo molybdenum, utamane kanggo nambah pelumasan lan nambah resistensi nyandhang ring piston.Umume dering piston liyane kaleng utawa difosfat, utamane kanggo nambah resistensi nyandhang.Yen ring piston dipasang kanthi ora bener utawa panyegelan ora apik, bakal nyebabake lenga ing tembok silinder munggah menyang kamar pembakaran lan diobong nganggo campuran, nyebabake kobong lenga.Yen reresik cocog antarane ring piston lan tembok silinder cilik banget utawa ring piston macet ing alur ring amarga celengan karbon, etc., Nalika piston reciprocates munggah lan mudhun, tembok silinder kamungkinan bakal scratched.Alur jero dibentuk ing tembok, sing asring diarani minangka fenomena "narik silinder".Tembok silinder nduweni alur lan kinerja sealing sing kurang apik, sing uga bakal nyebabake kobong lenga.Mulane, kondisi kerja piston kudu dipriksa kanthi rutin supaya ora kedadeyan ing rong kahanan ing ndhuwur lan mesthekake yen mesin mlaku kanthi apik.
Syarat teknis
1. Iku kudu cukup kekuatan, rigidity, massa cilik lan bobot entheng kanggo mesthekake pasukan inersia minimal.
2. Konduktivitas termal sing apik, tahan suhu dhuwur, resistensi tekanan dhuwur, tahan korosi, kapasitas boros panas sing cukup, lan area pemanasan cilik.
3. Sampeyan kudu duwe koefisien gesekan cilik antarane piston lan tembok piston.
4. Nalika owah-owahan suhu, owah-owahan ukuran lan wangun kudu cilik, lan longkangan minimal antarane tembok silinder lan tembok silinder kudu maintained.
5. Koefisien ekspansi termal cilik, gravitasi spesifik cilik, lan nduweni resistance nyandhang apik lan kekuatan termal.
