钻式抽沙船泵性能表中的吸程是指常温清水条件下泵的抗汽蚀特性。采沙船在抽送泥沙作业时应尽可能使泵的进口压力为正压。泥沙中含有较大固体颗粒时泵的流量扬程也会受到影响，选型时应对介质情况予以考量。挖沙船泥沙泵在工作现场固定后，应先检查原动机主轴与泵主轴是否在同一轴线上，若不同轴应即作精准调整。

Drilling pumping sand pump performance in the absorption process refers to the anti cavitation characteristics under the condition of room temperature water pump. Sand mining in sediment pumping operations should as far as possible so that the pump inlet pressure for positive pressure. Sediment containing larger solids when the pump flow head will be affected, the selection of the media to consider the situation. Dredger mud pump is fixed at the work site, should first check the prime mover shaft and the pump shaft is in the same axis, if different shaft should be that for accurate adjustment.

钻式抽沙船的进出水管路应有承载支撑，避免管路重力施加于泵体。管路安装应从泵进出口法兰向外延伸，并立即做好支撑定位。泥沙泵工作时必须对填料室注入高压清水以保护轴封组件。主泵在正常工作时不得关闭高压清水泵。钻式抽沙船清水压力应大于泥沙泵工作压力。填料室组件在没有高压清水保护的情况下会很快磨损。

The drill water pipeline pump dredger should avoid pipeline bearing support, gravity imposed on the pump body. Pipeline installation should be extended from the pump inlet and outlet flange, and immediately do a good job supporting positioning. The mud pump must work to protect the high pressure water injection packing chamber seal assembly. The main pump in normal operation shall not be shut down the high pressure water pump. Drilling pumping sand water pressure should be greater than the pump working pressure of sediment. Packing chamber assembly in the absence of high pressure water to protect the case will soon wear.

钻式抽沙船大多数的用户由于在操作洗石机方法存在一定的误区，在洗石机工作中往往会出现一些异常问题，那么怎样才能减少这样异常问题以及对于异常问题怎么检修作相应的讲解！

Drilling pumping sand most users due to the presence of certain errors in the operation of the machine that wash stone, stone washing machine work often appear some abnormal problems, then how to reduce this anomaly and the anomaly problem how repaired corresponding explanations!

洗石机在启动前先用手旋转转子，检查机器各部有无异常现象。使用单位应根据现场具体情况，在三角皮带上安装防护设备后，钻式抽沙船才能运转。运转时不可进行修理及清理工作，严禁开机检修。不得加入超过规定尺寸之料石。机器应按固定方向旋转，不得反向旋转。

Washing machine first hand rotating rotor before starting, check the machine parts have no abnormal phenomenon. The use of units should be based on site conditions, installation of protective equipment in the triangle belt, drilling pumping sand in order to operate. Operation can not be carried out to repair and clean up the work is strictly prohibited boot. The size of the provisions shall be a member of more than stone. The machine shall be rotated in a fixed direction and shall not be rotated in reverse direction.

在机器运转时，如发现有不正常的振动或响声时，应立即停止加料，待箱内物料排尽后，立即停止电机，停机检查，排除故障后，才能继续运转。遇紧情况先停止电机，钻式抽沙船在开机前必须清除腔内物料，空载启动。

In the operation of the machine, if found to have abnormal vibration or sound, should immediately stop feeding, to be in the box after the material is discharged, immediately stop the motor, stop the inspection, troubleshooting, to continue to operate. In case of tight first stop the motor, drilling pumping sand must be removed from the cavity material before starting the no-load start.
