Kuwerengera kwa Mpweya Wotulutsa Mpweya ndi Kusankha Zida Zomangamanga mu Tunneling(2)

2. Kuwerengera kuchuluka kwa mpweya wofunikira pakumanga ngalande

Zomwe zimatsimikizira kuchuluka kwa mpweya wofunikira pomanga ngalandeyi ndi izi: kuchuluka kwa anthu omwe amagwira ntchito mumsewu nthawi imodzi;kuchuluka kwa zophulika zomwe zimagwiritsidwa ntchito pakuphulika kumodzi: liwiro lochepera la mphepo lotchulidwa mumsewu: kutuluka kwa mpweya wapoizoni ndi woopsa monga gasi ndi carbon monoxide, ndi kuchuluka kwa injini zoyatsira mkati zomwe zimagwiritsidwa ntchito mumsewu Dikirani.

2.1 Kuwerengera kuchuluka kwa mpweya molingana ndi mpweya wabwino womwe umafunika ndi kuchuluka kwa anthu omwe amagwira ntchito mumsewu nthawi imodzi.
Q=4N (1)
kumene:
Q - chofunika mpweya voliyumu mu ngalande;m³/mphindi;
4 - Mpweya wocheperako womwe uyenera kuperekedwa kwa munthu pa mphindi;m³/min•munthu
N - The pazipita chiwerengero cha anthu mu ngalandeyo pa nthawi yomweyo (kuphatikizapo kutsogolera yomanga);anthu.

2.2 Kuwerengeredwa molingana ndi kuchuluka kwa zophulika
Q=25A (2)
kumene:
25 - Mpweya wocheperako wofunikira pamphindi kuti uchepetse mpweya woyipa wopangidwa ndi kuphulika kwa kilogalamu iliyonse ya zophulika mpaka pansi pamlingo wovomerezeka mkati mwa nthawi yodziwika;m³/min•kg.

A - The pazipita kuchuluka kwa mabomba zofunika kuphulika kumodzi, kg.

2.3 Kuwerengeredwa molingana ndi liwiro lochepera lamphepo lomwe lafotokozedwa mumphangayo

Q≥V_min•S (3)

kumene:
V_min- liwiro lochepera lamphepo lofotokozedwa mumsewu;m/mphindi.
S - osachepera mtanda wagawo dera la zomangamanga ngalande;m².

2.4 Mawerengedwe malinga ndi linanena bungwe la poizoni ndi zoipa mpweya (gasi, mpweya woipa, etc.)

Q=100•q·k (4)

kumene:

100 - The coefficient analandira molingana ndi malamulo (gasi, mpweya woipa akutuluka mu ngalandeyo nkhope, mpweya woipa ndende osati apamwamba kuposa 1%).

q - mtheradi outflow wa poizoni ndi zoipa mpweya mu ngalandeyo, m³/min.Malinga ndi mtengo wapakati wa ziwerengero zoyezedwa.

k - kuchuluka kwa mpweya wapoizoni ndi woopsa womwe ukutuluka mumsewu.Ndi chiŵerengero cha voliyumu yothamanga kwambiri ndi voliyumu yothamanga kwambiri, yomwe imachokera ku ziwerengero zenizeni.Kawirikawiri pakati pa 1.5 ndi 2.0.

Mutatha kuwerengera molingana ndi njira zinayi zomwe zili pamwambazi, sankhani imodzi yomwe ili ndi mtengo waukulu kwambiri wa Q monga mtengo wa mpweya wofunikira popanga mpweya wabwino mumsewu, ndikusankha zipangizo zoyendetsera mpweya malinga ndi mtengo umenewu.Kuonjezera apo, chiwerengero cha makina oyatsira mkati ndi zipangizo zomwe zimagwiritsidwa ntchito mumsewu ziyenera kuganiziridwa, ndipo mphamvu ya mpweya wabwino iyenera kuwonjezeredwa moyenerera.
