Description

technical field

[0001] The invention belongs to the technical field of ships, in particular to a jet-type dredging ship. Background technique

[0002] Sand dredging boats, also known as dredging boats, are used for dredging sand in rivers and sea areas. The daily sand dredging capacity of sand dredging boats ranges from several thousand tons to tens of thousands of tons. The sand dredging ship is mainly carried out by sand pumping equipment. The sand dredging equipment includes a jet dredging device and a water pump device. The water pump device includes a starting device and a water pump. 1. The upper sand nozzle and upper sand pipe, the clear water pipe is connected with the water pump device, and the upper sand pipe is connected with the sand washing tank of the jet-type sand dredger.

[0003] The working principle of the sand pumping equipment is to continuously pump high-speed water into the clear water pipe through the water pump. When the high-speed water is sprayed...
