抽沙船，顧名思義，就是用來抽取泥沙的船只種類。作為河道清淤的主要設(shè)備，其抽沙能力與其各種配置有關(guān)。
在不同河道清淤，需使用不同的抽沙船。這些抽沙船，除配置不同外，大小也存在差異。
絞龍抽沙船是前置絞刀，利用絞刀旋轉(zhuǎn)把沙層攪動(dòng)的先進(jìn)設(shè)備，該抽沙船利用絞刀架的長短，決定船體的大小。一般絞刀架越長，船體也越長，挖深也越大。這是區(qū)別于射吸式抽沙船的一點(diǎn)，如射吸式抽沙船就不會(huì)因?yàn)榇w的加長而變大。
抽沙船的吸沙泵是抽沙船的主要部件，了解并學(xué)會(huì)解決吸沙泵常見的問題可以使抽沙船更好地為我們所用。
吸沙泵在運(yùn)轉(zhuǎn)的過程中中突然泄漏是常見的問題之一，這些吸沙泵只有少數(shù)情況是因?yàn)槟p過度或已達(dá)到使用壽命造成的，大部分情況還是由于工況變化較大和操作不當(dāng)引起。所以說，了解并合理使用才是正確的。那么，那些原因可能導(dǎo)致吸沙泵出現(xiàn)問題呢？
1、抽沙船經(jīng)過抽空、氣蝕或較長時(shí)間的憋壓，而造成的密封破壞；
2、抽沙泵的實(shí)際輸出量偏小，使得大量介質(zhì)在泵內(nèi)循環(huán)，熱量積聚，引起介質(zhì)氣化，導(dǎo)致密封失效；
3、回流量偏大，導(dǎo)致吸入管側(cè)容器底部的沉渣泛起，損壞密封；
4、抽沙船在經(jīng)過較長時(shí)間的停運(yùn)后重啟，沒有手動(dòng)盤車，劇烈摩擦粘連而扯壞密封面；
5、吸入介質(zhì)中腐蝕性、聚合性和結(jié)膠性物質(zhì)過多；
6、環(huán)境溫度急劇變化。
Pumping sand, as the name suggests, is used to extract the sediment type of vessels. As the main equipment of river dredging, the sand pumping capacity and various configurations of.

Dredging in different river, using different pumping sand. These pumping sand, in addition to the configuration of different, there are differences in size.
絞龍抽沙船是前置絞刀，利用絞刀旋轉(zhuǎn)把沙層攪動(dòng)的先進(jìn)設(shè)備，該抽沙船利用絞刀架的長短，決定船體的大小。一般絞刀架越長，船體也越長，挖深也越大。這是區(qū)別于射吸式抽沙船的一點(diǎn)，如射吸式抽沙船就不會(huì)因?yàn)榇w的加長而變大。
Auger suction dredger is pre reamer, by cutter rotation, the disturbing the sand of advanced equipment, the suction dredger cutter frame length of use, decided the hull size. The general bridge is long, the hull is longer, the greater the digging depth. This is the difference between a point on the jet suction dredger, such as jet suction dredger will not change because of lengthening hull.
抽沙船的吸沙泵是抽沙船的主要部件，了解并學(xué)會(huì)解決吸沙泵常見的問題可以使抽沙船更好地為我們所用。
Suction dredger sand suction pump is pumping sand is the main component, learn to understand and solve ceiling sand pump common problems can make pumping sand better for us.

Sand suction pump in the running process of sudden leakage is one of the common problems and the sand suction pump only a few conditions is because wear excessive or has reached caused by the use of life, in most cases is due to caused by improper behavior varies greatly and the operation. Therefore, understanding and reasonable use is correct. So, those reasons may lead to the problem of pumping sand pump it?
1、抽沙船經(jīng)過抽空、氣蝕或較長時(shí)間的憋壓，而造成的密封破壞；
1, pumping sand after a longer period of time or time, cavitation pressure, caused by the destruction of the sealed;
2、抽沙泵的實(shí)際輸出量偏小，使得大量介質(zhì)在泵內(nèi)循環(huán)，熱量積聚，引起介質(zhì)氣化，導(dǎo)致密封失效；
2, the actual output of pumping sand pump is small, so that a large number of medium circulating in the pump, heat accumulation, cause the media gasification, resulting in seal failure;
3、回流量偏大，導(dǎo)致吸入管側(cè)容器底部的沉渣泛起，損壞密封；
3, large back flow, leading to inhalation tube side of the container at the bottom of the dregs, damage the seal;
4、抽沙船在經(jīng)過較長時(shí)間的停運(yùn)后重啟，沒有手動(dòng)盤車，劇烈摩擦粘連而扯壞密封面；
4, pumping sand after outage a long time after the restart, no manual turning, the friction adhesion and brought bad sealing surface;
5、吸入介質(zhì)中腐蝕性、聚合性和結(jié)膠性物質(zhì)過多；
5, inhalation of medium corrosion, polymerization and knot of plastic material too much;
6、環(huán)境溫度急劇變化。
6, the sharp change in the environment temperature. |
