PENGERTIAN SISTEM HIDROLIK

Pengertian Sistem Hidrolik

1.         Pengertian Sistem Hidrolik

Sistem hidrolik merupakan suatu bentuk perubahan atau pemindahan daya dengan menggunakan media penghantar berupa fluida cair untuk memperoleh daya yang lebih besar dari daya awal yang dikeluarkan. Dimana fluida penghantar ini dinaikan tekanannya oleh pompa pembangkit tekanan yang kemudian diteruskan ke silinder kerja melalui pipa-pipa saluran dan katup-katup. Gerakan translasi batang piston dari silinder
kerja yang diakibatkan oleh tekanan fluida pada ruang silinder dimanfaatkan untuk gerak maju dan mundur.

Dasar- dasar Sistem Hidrolik
a. Hukum Pascal
Prinsip dasar sistem hidrolik berasal dari hukum pascal, dimana tekanan dalam fluida statis harus mempunyai sifat-sifat sebagai berikut:
1) Tekanan bekerja tegak lurus pada permukaan bidang.
2) Tekanan disetiap titik sama untuk semua arah.
3) Tekanan yang diberikan kesebagian fluida dalam tempat tertutup, merambat secara seragam ke bagian lain fluida.
