【正文】 母,壓緊彈簧,則升高負壓設(shè)定值;放松彈簧,則降低負壓設(shè)定值,每次可以 擰 2 圈螺母左右進行調(diào)整(impact the spring, raise set value, release spring, reduce the set value。 2 circle each time); 調(diào)整完畢后,關(guān)機,安裝好放空閥調(diào)整蓋(after finished, fit the valve); 如果經(jīng)過幾次調(diào)整,仍不能調(diào)到設(shè)定值, 則應(yīng)清洗或更換放空閥。If the valve can not be regulate, please change it.廣東火電工程總公司印尼棉蘭 EPC 項目負壓真空清掃設(shè)備工程專用 八 管網(wǎng)系統(tǒng)操作規(guī)程及注意事項pipe amp。 dustsuck manipulating noticeⅠ、查漏(check leakage)負壓吸塵管網(wǎng)系統(tǒng)要求一個密封的管網(wǎng)系統(tǒng),保證能進行吸塵作業(yè)。在管網(wǎng)系統(tǒng)安裝完畢后,應(yīng)該進行 查漏試驗。Vacuum dust suck require a sealed pipe which ensure working task. After installing pipe , the examination of leakage should proceed. 1. 確認主機正常(confirm that vacuum machine is good)查漏前應(yīng)該首先確認主機工作正常,方法是:堵住主機入口總管,觀察真空表,如果負壓上升到使安全保 護放空閥放空, 則可確 認主機沒有問題。Plug the suck mouth, the vacuum rate will go up to set value soon. If so, it canbe confirmed that vacuum machine is good.2. 檢查管網(wǎng)泄漏(inspecting leakage of pipe )檢查管網(wǎng)系統(tǒng)泄漏前,應(yīng)該關(guān)閉所有的吸塵口,將主機連接在管網(wǎng)系統(tǒng)總管終端上,然后啟動主機和真空 泵, 觀察真空表,如果在 2~3 分鐘內(nèi),負壓升高并達到保護值而自動放空,說 明管網(wǎng)密封良好;如果經(jīng)過一段時間(5~10 分鐘),負壓仍達不到最高保護值放空, 說明管網(wǎng)系統(tǒng)有漏氣點。這時應(yīng)該逐點檢查管網(wǎng)的所有連接部位,如果有漏風(fēng)處 ,這個部位會發(fā)出漏風(fēng) 的嘯叫聲,用 軟塑料紙靠近漏風(fēng)點也可以找到漏風(fēng)部位。將漏 風(fēng)點擰緊或采取其它密封措施。Before inspecting leakage, all suck mouth should be closed. After linking machine to pipe line, runn the vacuum device. The pipe is airproof good if vacuum rate go up to set value in 2~3 minute. 廣東火電工程總公司印尼棉蘭 EPC 項目負壓真空清掃設(shè)備工程專用 Ortherwise, 5~10 minute later ,if vacuum rate can not reach set value, the pipe is leakage. Checking the pipe and joint, where whistle, where leakage.廣東火電工程總公司印尼棉蘭 EPC 項目負壓真空清掃設(shè)備工程專用 Ⅱ、吸塵操作規(guī)程和注意事項(dustsuck manipulating notice)正常吸塵作業(yè)時,負壓值保持在 ~。管口敞開時,空載時的負壓不會超過 barVacuum rate will keep in ~ normally. When suck mouth open, it will not exceed bar.1. 吸嘴和吸塵軟管的選擇和使用(suck nozzle and tube) 負壓吸塵是依靠空氣流將物料懸浮帶走的,所以吸料時必須保證吸嘴有足夠的流量的空氣進入吸口, 切勿將整個吸嘴連同進風(fēng)口“埋入”料堆。Vacuum dust clearing depend on air flows. Adequate air capacity is need to carry the powder. All nozzle mouth should not be embedded into the powder.過長、過細和過多彎曲的軟管會增大阻力,容易造成堵塞,所以要 選擇適當(dāng)?shù)能浌茏鳂I(yè),并在工作時盡可能讓軟管處于平直狀態(tài)。Too long、too thin tube or much bent should increase resistance. Select suitable size tube, make tube to straight line. 2.先連接吸口,后開真空泵( link suck mouth frist, start machine)如果管網(wǎng)系統(tǒng)密封良好,全部快速接頭用防塵塞堵住,啟動真空泵后,管網(wǎng)內(nèi)形成高負壓,防塵塞將被吸住而 難于打開。所以在啟動真空泵之前應(yīng)該先打開1~2 個防塵塞,連接吸塵軟 管和吸嘴。If all the suck mouth is plug up, it is difficult to open fast joint during working. it is necessary dismount 1~2 fast joint before start machine.廣東火電工程總公司印尼棉蘭 EPC 項目負壓真空清掃設(shè)備工程專用 3.更換吸口(exchange the suck mouth)一般從最遠或最近點開始吸塵作業(yè),當(dāng)?shù)谝粋€吸點周圍吸干凈后,先打開第二個吸口的防塵塞,再取下第一個吸口的軟管和吸嘴并用防塵塞關(guān)閉,將軟管和吸嘴安裝在第二個吸口上繼續(xù)作業(yè),依次類推。When one suck mouth is finished, please open the second mouth first, then close finished mouth.注意:蓋防塵塞時必須小心,避免夾手!Notice: when installing antidust jam, be carefully not nip hand.4.多個人同時吸塵(multiperson working at same time)同時打開吸口吸塵的數(shù)量隨主機馬力大小不同而不同,50 馬力的主機,當(dāng)設(shè)備完好、管網(wǎng)密封良好時可以同 時打開 2 個 3吸口作業(yè),如果每個 3吸口配上3x2x2 軟 管“Y” 型接頭時 ,可以有 3 個人同時用 2吸嘴作業(yè)。同時打開的吸口要求相鄰。How many suck mouth can open to job depend the power. VACTA55 can do job by three person with 2” suck nozzles. 5. 排堵(eject jam)吸塵時,只要是吸口可以吸入的物料,在管網(wǎng)系統(tǒng)中一般不會形成堵塞,但有時吸入的鐵絲等異物也會造成局部堵塞,從軟管重量可以判斷是否堵塞,一般堵塞在不停主機情況下排堵,對于被堵塞的軟管,抬起向下摔動幾次就可以排堵,鋼管內(nèi)如果堵塞,可以用手 錘敲打、振 動排堵。用以上辦法不能排堵時,就要逐段拆除檢查和排堵。為防止物料在管網(wǎng)里積存,每次停機前應(yīng)該空吸 3~4 分鐘,吸盡管網(wǎng)內(nèi)殘留的物料。廣東火電工程總公司印尼棉蘭 EPC 項目負壓真空清掃設(shè)備工程專用 Some time, such as thread may cause jam in tube and pipe. If tube jam, it can be ejected by fall up and down the tube. If pipe jam, knocking , vibrating are good method.If jam can not be ejected through above method. Backout the pipe and eject jam.
