天然橡膠密封圈平墊寸尺的選擇的通常情況原理
（1）盡(jin)幾率抉擇薄的(de)(de)封(feng)(feng)(feng)(feng)口墊(dian)。封(feng)(feng)(feng)(feng)口墊(dian)標(biao)準(zhun)條件(jian)(jian)的(de)(de)板(ban)材(cai)高度和(he)(he)其(qi)結構、建(jian)筑材(cai)料、長度、密書(shu)皮的(de)(de)制造的(de)(de)現象(xiang)和(he)(he)封(feng)(feng)(feng)(feng)口物質等(deng)業內(nei)。比如對絕大越來越多(duo)數(shu)非材(cai)料封(feng)(feng)(feng)(feng)口墊(dian)一般來說，隨封(feng)(feng)(feng)(feng)口墊(dian)板(ban)材(cai)高度可(ke)以(yi)變(bian)少(shao)，其(qi)對抗(kang)壓(ya)力(li)應變(bian)放松(song)下來的(de)(de)作用會增多(duo)；薄的(de)(de)封(feng)(feng)(feng)(feng)口墊(dian)其(qi)相關爆漏(lou)于(yu)封(feng)(feng)(feng)(feng)口物質的(de)(de)范圍也少(shao)，沿封(feng)(feng)(feng)(feng)口墊(dian)本(ben)體論的(de)(de)滲漏(lou)也繼(ji)而可(ke)以(yi)變(bian)少(shao)。為衡量封(feng)(feng)(feng)(feng)口墊(dian)務必合(he)理補充卡箍部(bu)(bu)(bu)片(pian)部(bu)(bu)(bu)密書(shu)皮的(de)(de)凹(ao)凸(tu)(tu)不平(ping)和(he)(he)跌(die)宕起伏(fu)凹(ao)凸(tu)(tu)不平(ping)的(de)(de)標(biao)準(zhun)條件(jian)(jian)，封(feng)(feng)(feng)(feng)口墊(dian)的(de)(de)小(xiao)板(ban)材(cai)高度決定(ding)于(yu)卡箍部(bu)(bu)(bu)片(pian)部(bu)(bu)(bu)外觀的(de)(de)滑度、封(feng)(feng)(feng)(feng)口墊(dian)的(de)(de)壓(ya)縮視頻性(xing)、封(feng)(feng)(feng)(feng)口墊(dian)壓(ya)力(li)應變(bian)、卡箍部(bu)(bu)(bu)片(pian)部(bu)(bu)(bu)的(de)(de)偏轉(zhuan)層度等(deng)。如果(guo)你卡箍部(bu)(bu)(bu)片(pian)部(bu)(bu)(bu)是平(ping)行面的(de)(de)，則對非材(cai)料平(ping)封(feng)(feng)(feng)(feng)口墊(dian)，其(qi)小(xiao)板(ban)材(cai)高度可(ke)由下式計算方式。
