ʻO ka hoʻoulu ʻana he nui bypass valve
wehewehe:
I ka wā o ka wili ʻana, i ka wā i hoʻokō ʻia ai ke kī ʻana o ka pūnāwai a paʻa ka bit bore. Hiki ke wehe ʻia ka valve by-pass e hele i ke kahe wai a me ka pepehi maikaʻi. Ma mua o ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻana i ke kinoea, e hoʻonoho ʻia ka valve by-pass ma kahi kokoke a i ʻole ma ka bit.
Ke kiʻekiʻe a paʻa ʻia ke kiʻi maikaʻi a paʻa paha ke kaomi ʻana, hiki ke lawe ʻia kēia mau ʻanuʻu e wehe i ka valve by-pass:
1. E hoʻokuʻu iā Kelly a hoʻokuʻu i loko o ke kinipōpō kila (a i ʻole ka poepoe Nylon) i lawe ʻia e ka mea hana;
2. Hoʻopili me Kelly;
3. E hookomo i ka poepoe i loko o ka waihona ma ke kaa ana o ka pamu;
4. Ke pani ʻia ka wai, hiki ke ʻoki ʻia ka pine shear ma ka hoʻohui ʻana i ka 0.5 ~ 1.5Mpa kaomi ma mua o ke kaomi ʻana o ka paila mua;
5. Ma hope o ka ʻako ʻia ʻana o ka pine, neʻe ka lima o ka sila i lalo e wehe i ka puka hoʻokuʻu a hāʻule iho ke kaomi ʻana i lalo, a laila hiki ke hoʻomaka i ka holo maʻamau a me ka hana pepehi maikaʻi.
