41、Laying 布料Laying is an important problem to the truck-mounted concrete line pump.If laying isnt on time,the phenomenon of pipe jam will happen.The methods are as follows:用車載式混凝土泵車輸送混凝土，布料是很重要的問題。如果布料不及時，就會發(fā)生積 料、堆料現(xiàn)象，使泵送壓力升高，易發(fā)生堵管。用車載式混凝土泵車施工時，一般可用下 述方法進行布料：Laying with groove 用溜槽布料In order to install

42、a inclined groove at the exit of the concrete pipe,the pipe should install higher and the groove can make revolving.將管道安裝得高一些（1.21.5m），在混凝土輸送管出口處接一斜溜槽。溜槽可做成可 旋轉(zhuǎn)的，使布料面積增大。Laying with the handcart用手推車搬運布料Its used to affuse few concrete and some special places which the hose cant reach.這是一種簡易的布料方法，用于混凝

43、土灌注量不大或某些特殊部位布料桿布料軟管達不 到的地方。Laying with hose用布料軟管布料In small pipe condition,laying with hose is very suitable.The hoses length has 3m and 5m and the minimal bend radiu is no less than 1.5m.這是應(yīng)用較多的一種布料方法，尤其在小管徑情況下，布料軟管重量輕移動方便，在樓 面上布料是很適用的。布料軟管的長度有3m、5m兩種，工作時繩子捆住軟管出口處，拖到需 澆注的各處，工作時軟管最小彎曲半徑不得小于1.5m。Layi

44、ng with placing boom 布料桿布料Laying with placing boom can quick and conveniently laying and the phenomenon of pipe jam isnt easily happen.In construction,the placing boom can laying at any places in available scope,it improves the efficiency and lighten the labor intensity.采用布料桿布料，可以迅速、方便地進行大范圍布料，不容易發(fā)生

45、積料，堵管等現(xiàn)象。 在施工中通常把布料桿放置在需要澆注層面的中央，可旋轉(zhuǎn)360，可以在布料桿有效范圍內(nèi) 任意位置進行布料，這樣就可以大大地提高混凝土澆注施工效率，減輕工人的勞動強度，它 是一種較理想的混凝土布料機械。The analysis of ZOOMLIONs core pumping technology 中聯(lián)重科核心泵送技術(shù)分析Double pumps provide oil intermittently 預(yù)壓式雙泵間歇供油The lubrication system has force filter and double pumps provide oil intermittent

56、puter control. If pipe is jammed during pumping, after the computer judges ,it will switch to high pressure automatically and then switch to low pressure.在計算機的控制下液壓系統(tǒng)根據(jù)泵送的距離和高度自動選擇高壓或低壓。在泵送過程中 如出現(xiàn)堵管計算機經(jīng)過判斷后自動切換成高壓加以排除，然后自動切換到低壓狀態(tài)。During operation,only need pressing the electricity button lightly, al

57、l will be completed.操作的時候，只需要輕輕地一按這個電控按鈕，就全部完成，不用拆管，沒有任何泄漏。 可以快速排除堵管。這樣做完全突破了傳統(tǒng)的先停機再切換的模式，在泵送過程中都可以切 換，大大地豐富了泵的操作技巧。Quick-release piston technology 砼活塞自動退回技術(shù)Only need pressing the key,the piston will untread to the water tank and it saves time and labor.只需簡單的按鍵，就能輕松地將砼活塞自動退回到水箱中，使傳統(tǒng)方式更換活塞所需的2 小時，縮短到

58、15分種以內(nèi)，省時又省力。In order to avoid piston abrasion during construction, pistons should be checked each time before pumping.因退出極為方便，可在每次泵送作業(yè)前先檢查砼活塞避免因砼活塞磨損引起的施工中斷。The quick replacement piston equipment adopts hydraulic and machinery doubly limit ,it is safe and reliable.采用液壓機械雙重限位，安全可靠,避免單一液壓限位，閥誤動作或油缸長時

59、間使用后泄 漏量增大，將混凝土帶進水箱的安全隱患。Oil cleanness油液清潔度Cleanness is the reliable guarantee of the system. In practice, 80% faults arouse from cleanness.The cleanness of concrete pump in ZOOMLION through some measures can be ensured over NAS8:液壓系統(tǒng)清洗度是系統(tǒng)運行可靠的保證，實踐證明，液壓系統(tǒng)80%的故障都是因為系統(tǒng) 不清潔引起的。中聯(lián)拖泵清潔度通過下述措施保障系統(tǒng)清潔度在NA

60、S8級以上：Circulation wash after assembly is the premise of the system cleaning.After assembly, usingspecial filter car to circulate washing for 10 hours, it can clean out the dirt completely.裝配后的循環(huán)沖洗一一系統(tǒng)初裝后的嚴(yán)格清洗是系統(tǒng)清潔的前提。整機裝配后，用專用 過濾小車進行了10小時的循環(huán)過濾沖洗，將制造過程中殘留的污質(zhì)徹底清除。Using high quality hydraulic oil is th
