抽沙船，顾名思义，就是用来抽取泥沙的船只种类。作为河道清淤的主要设备，其抽沙能力与其各种配置有关。
 在不同河道清淤，需使用不同的抽沙船。这些抽沙船，除配置不同外，大小也存在差异。
 绞龙抽沙船是前置绞刀，利用绞刀旋转把沙层搅动的先进设备，该抽沙船利用绞刀架的长短，决定船体的大小。一般绞刀架越长，船体也越长，挖深也越大。这是区别于射吸式抽沙船的一点，如射吸式抽沙船就不会因为船体的加长而变大。
 抽沙船的吸沙泵是抽沙船的主要部件，了解并学会解决吸沙泵常见的问题可以使抽沙船更好地为我们所用。
 吸沙泵在运转的过程中中突然泄漏是常见的问题之一，这些吸沙泵只有少数情况是因为磨损过度或已达到使用寿命造成的，大部分情况还是由于工况变化较大和操作不当引起。所以说，了解并合理使用才是正确的。那么，那些原因可能导致吸沙泵出现问题呢？
 1、抽沙船经过抽空、气蚀或较长时间的憋压，而造成的密封破坏；
 2、抽沙泵的实际输出量偏小，使得大量介质在泵内循环，热量积聚，引起介质气化，导致密封失效；
 3、回流量偏大，导致吸入管侧容器底部的沉渣泛起，损坏密封；
  4、抽沙船在经过较长时间的停运后重启，没有手动盘车，剧烈摩擦粘连而扯坏密封面；
 5、吸入介质中腐蚀性、聚合性和结胶性物质过多；
 6、环境温度急剧变化。

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.

在不同河道清淤，需使用不同的抽沙船。这些抽沙船，除配置不同外，大小也存在差异。

Dredging in different river, using different pumping sand. These pumping sand, in addition to the configuration of different, there are differences in size.

绞龙抽沙船是前置绞刀，利用绞刀旋转把沙层搅动的先进设备，该抽沙船利用绞刀架的长短，决定船体的大小。一般绞刀架越长，船体也越长，挖深也越大。这是区别于射吸式抽沙船的一点，如射吸式抽沙船就不会因为船体的加长而变大。

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，了解并学会解决吸沙泵常见的问题可以使抽沙船更好地为我们所用。

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.

吸沙泵在运转的过程中中突然泄漏是常见的问题之一，这些吸沙泵只有少数情况是因为磨损过度或已达到使用寿命造成的，大部分情况还是由于工况变化较大和操作不当引起。所以说，了解并合理使用才是正确的。那么，那些原因可能导致吸沙泵出现问题呢？

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、抽沙船经过抽空、气蚀或较长时间的憋压，而造成的密封破坏；

1, pumping sand after a longer period of time or time, cavitation pressure, caused by the destruction of the sealed;

2、抽沙泵的实际输出量偏小，使得大量介质在泵内循环，热量积聚，引起介质气化，导致密封失效；

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，导致吸入管侧容器底部的沉渣泛起，损坏密封；

3, large back flow, leading to inhalation tube side of the container at the bottom of the dregs, damage the seal;

4、抽沙船在经过较长时间的停运后重启，没有手动盘车，剧烈摩擦粘连而扯坏密封面；

4, pumping sand after outage a long time after the restart, no manual turning, the friction adhesion and brought bad sealing surface;

5、吸入介质中腐蚀性、聚合性和结胶性物质过多；

5, inhalation of medium corrosion, polymerization and knot of plastic material too much;

6、环境温度急剧变化。

6, the sharp change in the environment temperature.
