冠诚钻探抽沙船：
抽沙船，又称抽沙王，抽沙机械，顾名思义即沙石采掘工具，多为流动作业之用。内陆河道抽沙船日采沙能力几十吨、到几千吨不等。船体采用拼装式箱型结构。配有筛选装置、提升装置、管道传送装置等。通过动力机驱动砂泵，通过管道把沙子输送到指定地点。 大型河道抽沙船机械化和自动化程度极高，一条华源抽沙船即可成为一个生产单位，可以实行采沙和沙石分离精选全过程。抽沙船分单抽型抽沙船和双抽型抽沙船， 淘铁抽沙船，淘金抽沙船， 普通型抽沙船，异型抽沙船1）开机前先对整个机械的传动系统及机器油料进行检查，然后开动后边拉输送带的柴油机，拉开离合器，发动柴油机，慢慢动松离合器，将转速调至正常。再发动抽砂泵的柴油机。 （2）两柴油机起动后。将转速调至需要速度。然后松开龙头刹车。将其放下，等看到沙管出口沙子含量浓度达到20%-40%之间，可停止下放

]Crown-drilling pumping sand:
Pumping sand, also known as the king of pumping sand, sand pumping machinery, as the name suggests that sand mining tools, mostly for use of mobile operations. Inland river sand mining capacity of pumping sand day dozens of tons, to thousands of tonnes. Hull assembled using box-type structure. With a screening device, lifting devices, piped devices. Sand pump driven by power machine, the sand transported by pipeline to a designated location. Large river sand pumping high degree of mechanization and automation, a Huayuan pumping sand can become a production unit that can carry out mining of sand and gravel separate selection process. Pumping sand pumping sub-type single and double pumping type pumping sand pumping sand, scouring sand pumping iron, gold pumping sand, ordinary type pumping sand, shaped pumping sand 1) before the first turn of the entire mechanical drive system and machine oil to be checked, and then pull back the belt starting diesel engines, pull the clutch, the engine diesel, slowly move the clutch loose, will speed adjusted properly. Then launch diesel pumping sand pump. (2) two diesel engine after starting. The speed is adjusted to the need for speed. Then release the brake leader. It down, and so see the sand content of the sand pipe outlet concentration between 20% -40%, you can stop the decentralization
