德國(guó)rexroth力士樂(lè)閥的安裝維護(hù)

脈沖膜片閥專為除塵設(shè)備的應(yīng)用設(shè)計(jì)，具有高流量，長(zhǎng)壽命和快速開(kāi)/關(guān)的特點(diǎn)，從而保證可靠經(jīng)濟(jì)的工作；角形閥體，無(wú)彈簧結(jié)構(gòu)，以及特殊的隔膜組件給了除塵設(shè)備應(yīng)用所需的*的操作特點(diǎn)；集成旋壓接頭設(shè)計(jì)，便于安裝，無(wú)須螺紋連接管；高品質(zhì)膜片，耐磨，長(zhǎng)壽命(即使在相當(dāng)惡劣的條件下工作)電磁閥本身結(jié)構(gòu)簡(jiǎn)單，價(jià)格也低，比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。

德國(guó)rexroth力士樂(lè)閥的安裝維護(hù)更顯著的是所組成的自控系統(tǒng)簡(jiǎn)單得多，價(jià)格要低得多。由于電磁閥是開(kāi)關(guān)信號(hào)控制，與工控計(jì)算機(jī)連接十分方便。在當(dāng)今電腦普及，價(jià)格大幅下降的時(shí)代，電磁閥的優(yōu)勢(shì)就 加明顯。動(dòng)作快遞，功率微小，外形輕巧。響應(yīng)時(shí)間可以短至幾個(gè)毫秒，即使是先導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。

由于自成回路，比之其它自控閥反應(yīng)更靈敏。設(shè)計(jì)得當(dāng)?shù)碾姶砰y線圈功率消耗很低，屬節(jié)能產(chǎn)品；還可做到只需觸發(fā)動(dòng)作，自動(dòng)保持閥位，平時(shí)一點(diǎn)也不耗電。電磁閥外形尺寸小，既節(jié)省空間，又輕巧美觀。調(diào)節(jié)精度受限，適用介質(zhì)受限。通常只有開(kāi)關(guān)兩種狀態(tài)，閥芯只能處于兩個(gè)極限位置，不能連續(xù)調(diào)節(jié)，(力圖突破的新構(gòu)思不少，但還都處于試驗(yàn)試用階段)所以調(diào)節(jié)精度還受到一定限制。電磁閥對(duì)介質(zhì)潔凈度有較高要求，含顆粒狀的介質(zhì)不能適用，如屬雜質(zhì)須先濾去。另外，粘稠狀介質(zhì)不能適用，而且，特定的產(chǎn)品適用的介質(zhì)粘度范圍相對(duì)較窄
