水下液压动力站双绞吸机 / Twin Cutter Suction Machine of Underwater Hydraulic Power Station

设计概述 Introduction

水下液压动力站双绞吸机是一款用于对水下硬土层、黏土层卵石层清理和挖掘的水下取土设备。

整机采用扭矩更大的液压方式驱动，给绞龙头提供更大的负载能力，应对水下各种土层工况的绞吸工作。通过对绞龙头水下转速、压力、温度传感器的监测，实现绞吸机工作状态的现场数字化显示，工作数据可实时传输，实现远程工程指挥。采用增压齿叶，在吸泥时提升泥吸绞力，绞头两侧配有高压水枪可以清理绞头上的板结淤泥，吸泥口可配有渲浆泵或气举，将绞吸后的泥浆抽走。

The twin cutter suction machine of underwater hydraulic power station is a kind of underwater soil sampling equipment used for cleaning and excavating underwater hard soil layer, clay layer and pebble layer.

The whole machine is driven by hydraulic mode with greater torque, which can provide greater load capacity for the cutter-suction head and cope with the cutter suction work under various  soil conditions. Through the monitoring of the rotary speed, pressure and temperature sensors of the cutter-suction head, the working state of the cutter suction machine can be displayed  digitally on site, and the working data can be transmitted in real time to realize the remote engineering command. Pressure boosting toothed blades are used to improve the suction and stranding force of mud during mud suction. High pressure water guns are equipped on both sides of the cutter head to clean the hardened sludge on the cutter head. The mud suction port can be equipped with a slurry pump or air lift to pump out the mud after cutter suction.

采用水下动力站专利技术，减少了现场作业面的场地占用率，把具备庞大作业能力的SS-400kW 液压动力站集成在水下，减少设备故障率，加大绞头的扭矩，因此水下液压站绞龙头比现有绞吸设备有以下优势：

• 采用液压驱动的绞龙头，具备超强的扭力及过载能力；

• 液压动力站集成在水下，解决了散热及液压传输的压力损耗问题，

• 具有电机保护功能，绞龙头堵转后，限压阀开启，电机照常运转，

• 具有数字化显示功能，通过传感器将转速，温度、 压力等数据显示在控制面板上，使设备操作人员更直观、有效地进行操作，提高挖掘的效率。

Advantages:

The patented technology of underwater power station is adopted to reduce the site occupation rate of the field working surface. The ss-400kw hydraulic power station with huge operation capacity is integrated under the water to reduce the equipment failure rate and increase the torque of the cutter head. Therefore, the cutter head of the underwater hydraulic station has the following advantages over the existing cutter suction equipment:

• Hydraulic driven cutter head with super torque and overload capacity;

• The hydraulic power station is integrated underwater to solve the pressure loss problem of heat dissipation and hydraulic transmission;

• it has motor protection function. After the cutter head is locked, the pressure limiting valve is opened and the motor operates normally;

• With digital display function, the speed, temperature, pressure and other data are displayed on the control panel through the sensor, so that the equipment operators can operate more intuitively and effectively, and improve the efficiency of mining.
