Low Pressure DTH Hammer
The down-the-bolonganpalu dthyaiku piranti sing nggunakake udara tekan minangka sumber daya lan nggunakake gerakan bola-bali piston ingpalukanggo impact bit pengeboran kanggo break rock. The down-the-bolonganpalu dthminangka piranti kerja saka pengeboran mudhun-bolongan. Miturut tekanan kerja sakapalu dth, bisa dipérang dadi tekanan rendahpalu dth(tekanan kerja 0.5 ~ 0.7Mpa), tekanan mediumpalu dth(0.7~1.2Mpa) lan tekanan dhuwurpalu dth(ndhuwur 1.2Mpa); miturut cara distribusi gas lan karakteristik struktural sakapalu dth, bisa dipérang dadi jinis valved lan valveless; miturut tatanan saka tengah liwat bolongan saka down-the-bolonganpalu dth, bisa dipérang dadi biasa mudhun-the-bolonganpalu dthlan mbalikke sirkulasi mudhun-the-bolonganpalu dth.
Aplikasi:
Iki digunakake sacara wiyar ing pertambangan terbuka lan pertambangan bijih lemah skala gedhe, rekayasa jangkar, penggalian lan pengeboran watu, pertambangan panas bumi sumur banyu, teknik konstruksi pengeboran batu lan konstruksi teknik skala gedhe., lsp.
Fitur
1 Tekanan udara operasi antara 0.5Mpa lan0.7Mpa
2 Palu tanpa katup.
3 Struktur prasaja, gampang dirakit lan dibongkar, umur dawa.
4 Frekuensi impact sing luwih dhuwur lan kacepetan pengeboran luwih cepet.
5 Konsumsi hawa sing luwih murah lan konsumsi minyak sing luwih murah. A bolongan bisa dilatih ing katup mriksa kanggo nyedhiyani cuttings discharge luwih efisien.
6 Utamané cocok kanggo quarrying.
