Izinto ezingundoqo zesicoci soxinzelelo oluphezulu zihlala zenziwe ngempompo yesakhiwo seplunger. Zininzi iikholamu zeceramic okanye iikholamu zentsimbi ye-tungsten ngaphakathi. Imoto iqhagamshelwe yicrankshaft okanye idiski eccentric ukuguqula ukujikeleza Umzimba wesilinda uxhotyiswe ngevalve enye, kwaye inkqubo yokujikeleza kokungena kwamanzi-uxinzelelo-lwamanzi lwenziwa kukutyhala kwentonga yepiston. Kule nkqubo yomjikelo.

Ukuba ufuna ukwandisa uxinzelelo kwindawo yokuphuma kwamanzi, kufuneka ujikeleze i-valve elawula uxinzelelo. Uxinzelelo olulawula ivelufa lucinezela ikholamu yokutywina kwindawo yokuphuma yamanzi ngentwasahlobo yangaphakathi yoxinzelelo oluphezulu. Vula, ukhuphe ulwelo olunoxinzelelo oluphezulu, kwaye ugcine uxinzelelo kwisisu luzinzile.

Nangona kunjalo, impompo nganye yamanzi iya kuba noxinzelelo olulinganisiweyo kunye noxinzelelo oluphezulu. Sicebisa ukuba uyisebenzise ngaphakathi koxinzelelo olinganiselweyo, ngapha koko iya kukhawulezisa ukunxiba kwamalungu empompo kwaye ibangele ukuba imoto igqume ngokugqithisileyo, nto leyo eya kuchaphazela ubomi bempompo kwaye ibangele nomonakalo ongenakulungiseka.

Ngolwazi oluthe kratya malunga ne-washer yoxinzelelo, nceda unxibelelane nathi kwaye siya kuba kwinkonzo yakho nangaliphi na ixesha.
