Ngexesha lokusetyenziswa kweumatshini we-polyurethane foam, ngamanye amaxesha ngenxa yokusetyenziswa ngokungafanelekanga ngumqhubi okanye ezinye izizathu, ezinye iindawo zesixhobo ngokwazo zineengxaki, ezibangela ukuvalwa komatshini, okufana: intloko yokuxuba ivaliwe, i-valve ephezulu kunye nesezantsi yokubuyisela umva andinakukwazi ukuvala ezi iingxaki, kwaye ulwazi oludlulileyo sele likuxelele malunga nezisombululo zezi ngxaki.Namhlanje, ndiza kukuxelela ukuba yintoni ebangela ukuguquguquka koxinzelelo kunye noxinzelelo olungonelanga lwesikhululo se-hydraulic?

1. Ukuguquguquka koxinzelelo kwisikhululo se-hydraulic Sihlala sidibana neenguqu ezahlukeneyo zoxinzelelo kunye nokunyuka okugqithisileyo okunyuka nokuhla.Oku kungenxa yokuba ingxowa yomoya ye-accumulator yaphukile okanye uxinzelelo lwenitrogen luncinci kakhulu.Singathatha indawo yenitrogen, egcwele initrogen.Qaphela ukuba uxinzelelo lwe-nitrogen alukwazi ukuphakama kakhulu okanye luphantsi kakhulu, kwaye uxinzelelo lunokufikelela kwi-100 MPa.

2. Uxinzelelo lwesikhululo se-hydraulic alukho phezulu.Ukuba akukho sihluzo kwindawo yokufunxa yempompo yehydraulic emdaka kakhulu, impompo ayinakukwazi ukufunxa ioyile.Akunakuphela nje ukuba uxinzelelo lweoli luya kuba phantsi, kodwa ukunxiba kwempompo kuya kukhawuleziswa.Ngoko ke, kufuneka kwenzeke ukucoca isihluzo somoya rhoqo.into esebenzayo.Ukunyuka koxinzelelo oluphantsi kukwadibaniswa nokunxiba kwiimpompo kunye neevalve zokunceda.Ngenxa yoyilo kunye neengxaki zokuhlalutya koqoqosho lwelizwe lam kunye nentlalontle, impompo yegiya esetyenziswayo ithanda ukuguga, kwaye kufuneka siyibuyisele rhoqo ukuba ifuna ukuphuculwa.Imithombo yevalve yokhuseleko ithanda ukudinwa ngexesha lokusetyenziswa kwemali eyinkunzi ixesha elide kwaye kufuneka ihlengahlengiswe rhoqo ukuthintela ukuvuza koxinzelelo.
