1彈簧的壓縮量
對(dui)於(yu)化(hua)工(gong)泵(beng)的(de)彈(dan)簧(huang)而(er)言(yan)，要(yao)對(dui)其(qi)壓(ya)縮(suo)量(liang)進(jin)行(xing)科(ke)學(xue)合(he)理(li)的(de)控(kong)製(zhi)，當(dang)壓(ya)縮(suo)量(liang)過(guo)大(da)時(shi)，就(jiu)會(hui)導(dao)致(zhi)摩(mo)擦(ca)副(fu)的(de)摩(mo)擦(ca)力(li)增(zeng)加(jia)，進(jin)而(er)大(da)大(da)增(zeng)加(jia)摩(mo)擦(ca)損(sun)失(shi)，隨(sui)著(zhe)摩(mo)擦(ca)副(fu)損(sun)失(shi)的(de)不(bu)斷(duan)增(zeng)加(jia)，就(jiu)會(hui)導(dao)致(zhi)改則化工泵改則機械密封失效，甚至還可能造成摩擦副燒毀，對化工生產的安全進行帶來嚴重的威脅;當彈簧的伸長量過大時，就可能導致彈簧無法對動環端麵進行有效的調節，進而使得泵的改則機械密封失效，從而造成化工泵出現泄漏的現象。
