class="NyNewsdetail_tips">更新時間：2018-12-22 點擊次數(shù)：3040</div> <div id="asq0aki4iuk" class="NyNewsdetail_con"> <div>　　對執(zhí)行機構(gòu)輸出力確定后，根據(jù)工藝使用環(huán)境要求，選擇相應(yīng)的執(zhí)行機構(gòu)。對于現(xiàn)場有防爆要求時，應(yīng)選用氣動執(zhí)行機構(gòu)，且接線盒為防爆型，不能選擇電動執(zhí)行機構(gòu)。如果<strong>氣動隔膜泵</strong>沒有防爆要求，則氣動、電動執(zhí)行機構(gòu)都可選用，但從節(jié)能方面考慮，應(yīng)盡量選用電動執(zhí)行機構(gòu)。對于液動執(zhí)行機構(gòu)，其使用不如氣動、電動執(zhí)行機構(gòu)廣泛，但具有調(diào)節(jié)精度高、動作速度快和平穩(wěn)的特點。<br /> </div><div>　　軸承：泵所配電機中的軸承勻采用封閉式軸承，正常使用時，免電機軸承的維護(hù)與保養(yǎng)。<br /> </div><div>　　機封密封：采用不銹鋼碳化硅、氟橡膠等材料制成。平衡式耐高溫、耐高壓，運行壽命長，不滲漏，對軸無磨損，不積水垢，保證工作環(huán)境的整潔。<br /> </div><div>　　運行平穩(wěn)，安全可靠：電機和水泵同軸直聯(lián)、同心度高，運行平穩(wěn)，安全可靠。<br /> </div><div>　　不銹鋼軸套：軸的機封位置是相對易被銹蝕之處，直聯(lián)式泵軸一旦被銹蝕，易造成機封密封失效。該泵此處采用鑲配不銹鋼軸套，避免銹蝕發(fā)生，提高了軸壽命，降低了運行維護(hù)成本。<br /> </div><div>　　1.當(dāng)隔膜失效時，輸送的物料會從排氣消聲器中噴出。<br /> </div><div>　　2.當(dāng)輸送易燃和有毒的流體時，請將排口接到遠(yuǎn)離工作區(qū)的安全地方。<br /> </div><div>　　3.請使用至少3/8"內(nèi)徑內(nèi)壁光滑的管道連接排氣口和消聲器。<br /> </div><div>　　4.接地要求符合當(dāng)?shù)胤ㄒ?guī)法律要求及現(xiàn)場的一些特殊要求的規(guī)定。<br /> </div><div>　　5.緊固好<strong>氣動隔膜泵</strong>及各連接管接頭，防止因振動撞擊擦產(chǎn)生靜電火花。使用抗靜電軟管。<br /> </div><div>　　6.要周期性的檢查和測試接地系統(tǒng)的可靠性，要求接地電阻小于100歐姆。<br /> </div><div>　　7.保持良好的排氣和通風(fēng)、遠(yuǎn)離易燃易爆和熱源。<br /> </div><div>　　8.保證流體中所含的大顆粒不超過泵的安全范圍通過顆粒直徑標(biāo)準(zhǔn)。<br /> </div><div>　　9.進(jìn)氣壓力不要超過泵的允許使用壓力，高于額定壓力的壓縮空氣可能導(dǎo)致人身傷害和財產(chǎn)的損失及損壞泵的性能。<br /> </div><div>　　10.保證泵壓的管道系統(tǒng)能承受所達(dá)到得較高的輸出壓力，保證驅(qū)動氣路系統(tǒng)的清潔和正常工作條件。<br /> </div><div>　　11.靜電火花可能引起爆炸導(dǎo)致人身傷亡事故和財產(chǎn)的損失，根據(jù)需要使用足夠大截面積的導(dǎo)線，把泵上的接地螺釘妥善可靠接地。<br /> </div><div>　　12.泵的排氣中可能含有固體物，不要將排氣口對著工作區(qū)或者人，以免造成人身傷害。<br /> </div><div>　　13.流體的高壓可能會導(dǎo)致嚴(yán)重的人身傷亡和財產(chǎn)損失，請不要在泵加壓時，對泵及料管系統(tǒng)進(jìn)行任何的維修工作，如要做維修時，先切斷泵的進(jìn)氣，打開旁通的卸壓機構(gòu)使管路系統(tǒng)卸壓，慢慢松開連接的各管道接頭。</div> </div> <div id="asq0aki4iuk"
