鉆探抽沙船,鉆探抽沙船廠家-青州冠誠重工機械有限公司

Drilling pumping sand, drilling pumping sand manufacturers - Preferred

冠誠鉆探抽沙船：
小型鉆探式抽沙船是一種異種抽沙設(shè)備，它較射吸式抽沙船和絞吸式抽沙船使用面比較低
鉆探式抽沙船主要適用在沙層表面有較厚的泥層，通過鉆桿與鉆頭將吸沙管鉆到泥層下面去，這樣避免了高壓水泵沖不起泥層的問題，從而解決了一些湖泊例如洪澤湖，駱馬湖等大型湖泊泥層下面采沙難的問題
小型鉆探式抽沙船一般下抽深度在5--20米，產(chǎn)量從20立方/小時——1000立方/小時不等
船體一般都是3節(jié)浮體，便于穩(wěn)定船體
動力一般都是比較大功率的柴油機或發(fā)電機組，抽沙泵是邳州泵或者石家莊泵，
鉆探式抽沙船一般制造工期較長，小型鉆探式抽沙船15-20天可以加工完成，而大型鉆探式抽沙船則需要45天甚至幾個月完成

Crown-drilling pumping sand:
Small drilling style pumping sand is a heterogeneous sand pumping equipment, it is higher than pumping sand and shoot suction cutter suction pump sand using relatively low surface
Drilling style pumping sand is mainly used in the surface of the sand layer thick mud layer, through the drill pipe and drill pipe drill mud will suck the sand layer below the go, thus avoiding the problem of high-pressure pumps can not afford the red mud layer, so as to solve some of the lakes such as lake, Luoma and other large lakes of mud layer below the difficult problem of sand mining
Small drilling under the general formula pumping sand pumping in 5--20 meters depth, yield ranging from 20 cubic meters / hour --1,000 cubic meters / hour
Hull are generally three floats, easy and stable hull
Power are generally more powerful diesel engine or generator set, pumping sand pump is pizhou Shijiazhuang pump or pumps,
Drilling style pumping sand general manufacturing period is longer, a small drilling type can be processed pumping sand 15-20 days to complete, while large pumping sand drilling type requires 45 days or even months to complete
