Chidacho ndi chaching'ono, chopepuka, chosavuta kuyenda komanso chosavuta kugwiritsa ntchito. Pogwiritsa ntchito luso lamakono lamagetsi, chida chokhacho chimatha kuwerengera kuchuluka kwa kabowo kakang'ono ka chidutswa choyesera malinga ngati mtengo wazitsulo wamadzimadzi umalowetsedwa.
Mtengo wa kabowo wa chidutswa chilichonse choyesera ndi mtengo wapakati wa gulu la zidutswa zoyeserera zimasindikizidwa ndi chosindikizira. Gulu lirilonse la zidutswa zoyesa siliri loposa 5. Izi zimagwiritsidwa ntchito makamaka pozindikira kutsekemera kwakukulu kwa pepala la fyuluta lomwe limagwiritsidwa ntchito mu fyuluta ya injini yoyaka mkati.
Mfundo yake ndi yakuti, malinga ndi mfundo ya capillary action, malinga ngati mpweya woyezedwa umakakamizika kupyolera mu pore ya chinthu choyezera chonyowa ndi madzi, kotero kuti mpweya umatulutsidwa mumadzimadzi mu chubu chachikulu cha pore cha chidutswa choyesera. , kupsyinjika chofunika pamene kuwira woyamba akutuluka pore, ntchito kudziwika mphamvu pamwamba pa madzi pa kutentha kuyeza, The kabowo pazipita ndi kabowo pafupifupi wa chidutswa mayeso akhoza kuwerengeredwa pogwiritsa ntchito equation capillary.
