穿孔式橋式濾水管 穿孔(kong)式濾(lv)水(shui)管是在井管上構成一定(ding)幾何形狀和一定(ding)規律布(bu)置(zhi)的進(jin)水(shui)孔(kong)眼(yan)而成。這種(zhong)(zhong)掛水(shui)管只能直接使(shi)用(yong)于粗砂以上的含水(shui)層中。因其(qi)進(jin)水(shui)孔(kong)眼(yan)的幾何形狀不同(tong)，大致又(you)可分為(wei)兩種(zhong)(zhong): 圓(yuan)孔(kong)(kong)式濾(lv)水(shui)管這是歷史簡單的(de)一種(zhong)型(xing)式。其(qi)(qi)孔(kong)(kong)眼可(ke)很據(ju)不(bu)同管材而用(yong)(yong)(yong)不(bu)同方法制(zhi)成。一般對金(jin)屬管和石棉水(shui)泥(ni)管多(duo)用(yong)(yong)(yong)鉆孔(kong)(kong)或沖壓而成，而對混凝土管只(zhi)能在(zai)澆筑成型(xing)時預留(liu)圓(yuan)孔(kong)(kong)。其(qi)(qi)孔(kong)(kong)眼的(de)大(da)小主(zhu)要(yao)按含水(shui)層(ceng)的(de)順粒粒徑(jing)而定，進水(shui)孔(kong)(kong)眼在(zai)管壁上的(de)布置形(xing)(xing)(xing)式，通常多(duo)采用(yong)(yong)(yong)交錯的(de)梅花形(xing)(xing)(xing)。進水(shui)孔(kong)(kong)眼的(de)相互位置，還可(ke)以(yi)分為等(deng)映三角形(xing)(xing)(xing)與等(deng)邊三角形(xing)(xing)(xing)兩種(zhong)。這樣初(chu)步選定出(chu)進水(shui)孔(kong)(kong)眼布置的(de)水(shui)平與垂直(zhi)孔(kong)(kong)距(ju)后，還應按對不(bu)同管材所要(yao)求(qiu)的(de)開孔(kong)(kong)率再加以(yi)調正，調整(zheng)使其(qi)(qi)孔(kong)(kong)距(ju)基本為整(zheng)數(shu)時以(yi)便于加工(gong)。

在當前國內外 橋式濾(lv)水(shui)管激烈的市場競爭中，闊恒鑫(xin)旺(十堰(yan)市(shi)分(fen)公司)本著“誠信為本、客戶至上、精益就精、質量優先”的立業宗旨，一如既往地提高現有 橋式(shi)濾(lv)水管(guan)產品質量，不斷努力提高現有 橋(qiao)式(shi)濾(lv)水管產品質量，不斷努力研究開發適用于客戶要求的 橋式濾(lv)水管產品，完善(shan)售后服(fu)務，保證用戶運(yun)行(xing)而(er)無(wu)后顧之憂。愿與各界朋友精誠合作，共謀發展！
