Njira yopangira ndi kufotokozera kwa magwiridwe antchito a kulongedza ma valve

1. Kufotokozera mtundu wa Graphite Packing

Pali mitundu itatu yotsatirayi ya zodzaza zomwe zimagwiritsidwa ntchito kwambiri mu:mavavu

Kupaka komwe kwagwiritsidwa ntchito mu pulojekitiyi ndi mtundu wotsegulira kamodzi womwe uli pa Chithunzi 1 ndi kupaka kozungulira komwe kuli pa Chithunzi 3. Zithunzi zenizeni ndi izi:

Chithunzi 1 Kulongedza kwa mtundu umodzi wotsegulira

Chithunzi 3 Kulongedza mphete

Ntchito zogwiritsira ntchito ma paketi awiri omwe ali pamwambapa ndi ofanana, kusiyana kuli pazochitika zosiyanasiyana zogwiritsira ntchito. Kupaka kotsegulira kamodzi ndikoyenera kusintha kupaka panthawi yokonza mavavu tsiku lililonse. Kupaka kumatha kusinthidwa pa intaneti, ndipo kuyika mphete yopakira ndikoyenera kukonzanso valavu. Kumagwiritsidwa ntchito pochotsa ndi kukonza.

2. Kufotokozera za makhalidwe a graphite kulongedza katundu

Malinga ndi zofunikira zaukadaulo za opanga zodzaza, chodzazacho chiyenera kukhala ndi mulingo wokhazikika, kotero padzakhala kulimba kuchokera mkati kupita kunja pambuyo poti kudzazidwa kwapangidwa. Mitundu iwiri ya zodzaza za graphite zotseguka zomwe zatchulidwa pamwambapa ndi zodzaza zoluka zomwe njira yake yopangira imalukidwa ndi ulusi wambiri wa graphite, ndipo kulimba kumatengedwa ndi mpata wolukidwa ndipo palibe chizindikiro chodziwikiratu cha kulakalaka kukula. Graphite yonyamula yozungulira yonyamula ndi chodzaza chaching'ono chokhala ndi mkati wocheperako. Pambuyo pa nthawi yayitali yoyima, kulimba kwamkati kudzawonetsa ming'alu pamwamba pa chodzazacho ndikutulutsa gawo ili la kupsinjika. Mtundu uwu wa chodzaza udzakhalabe wokhazikika ndipo sudzasintha pambuyo poti ming'alu ina yapangidwa. Ikakanikizidwanso, ming'aluyo imatha ndipo liwiro lobwerera limakwaniritsa zofunikira.

Izi ndi zofunikira zaukadaulo pa mphete zosinthika za graphite

3. Zokhudza kugwiritsa ntchito graphite packing

Kupaka graphite kumagwiritsidwa ntchito pamalo otsekedwa pakati pa tsinde la valavu ndi gland yopakira, ndipo kupakidwako kumakhala kopanikizika panthawi yogwira ntchito. Kaya ndi kupakidwa kotseguka kamodzi kapena kupakidwa kwa mphete yopakira, palibe kusiyana pa ntchito ya kupakidwa.

Chithunzi chotsatirachi chikuwonetsa momwe kulongedza kumagwirira ntchito (chithunzi cha mayeso olongedza)
