FESTO儲氣罐的檢驗要求:
通常作為簡單壓力容器,空壓機儲氣罐一直被認為是比較安全的一種特種設備,但也存在一定的危險性,在設計、制造質量、安裝標準、運行上、管理上如果出現問題,不符合規定要求,將會埋下隱患,在使用中可能發生嚴重事故,造成人員傷亡、設備損壞。
FESTO儲氣(qi)罐(guan)(guan)在安裝前需報(bao)裝,安裝后按(an)照(zhao)特種設備(bei)要(yao)求(qiu)進(jin)行(xing)辦理壓力(li)容器使用證、進(jin)行(xing)定(ding)(ding)(ding)期(qi)檢驗(yan)(yan)(yan)(yan),檢驗(yan)(yan)(yan)(yan)合格取得檢驗(yan)(yan)(yan)(yan)報(bao)告(gao)后,方可(ke)投(tou)入使用。按(an)照(zhao)儲氣(qi)罐(guan)(guan)的壓力(li)級別、使用年限要(yao)進(jin)行(xing)定(ding)(ding)(ding)期(qi)檢驗(yan)(yan)(yan)(yan),未經(jing)定(ding)(ding)(ding)檢合格的儲氣(qi)罐(guan)(guan)不(bu)得使用。儲氣(qi)罐(guan)(guan)的容積、壓力(li)高低應符合設計標(biao)準(zhun),不(bu)能隨便(bian)配置,一臺空(kong)氣(qi)壓縮(suo)機配備(bei)一臺儲氣(qi)罐(guan)(guan)。地(di)面空(kong)氣(qi)壓縮(suo)機站的儲氣(qi)罐(guan)(guan)應避免(mian)陽光直曬,儲氣(qi)罐(guan)(guan)必(bi)須(xu)有檢查孔,要(yao)定(ding)(ding)(ding)期(qi)清除罐(guan)(guan)內的油垢。
FESTO儲氣罐選型參數:
FESTO儲氣罐安裝空壓機之后,不僅能儲存壓縮空氣,減少由于壓縮機排氣不連續產生的壓力脈動,實現供氣和用氣的平衡,而且能降低壓縮空氣的溫度,減少過慮器和干燥劑的負荷。儲氣罐的選擇要注意如下問題:
1、殼體材料:儲氣罐屬于壓力容器,殼體常用的材料有Q235-B、16MnR、16MnDR三種。
2、儲氣(qi)罐總高(gao):氣(qi)源(yuan)房房體的(de)高(gao)度(du)(du)在2.9米左(zuo)右,考慮到氣(qi)源(yuan)經常移動運輸,需要(yao)保持足夠(gou)的(de)剛(gang)度(du)(du)和強度(du)(du),底座高(gao)度(du)(du)一般(ban)在300mm,屋頂部做成斜(xie)坡,造(zao)成氣(qi)源(yuan)房內的(de)凈高(gao)為(wei)2米,所有設備(bei)不能超過(guo)2米,否則(ze)無法安裝。以2.5m³儲氣(qi)罐為(wei)例(li)。
