Recently, the SD-01 Hailong series deep submersible pump integrated and manufactured by Nantong COSCO Auto was officially put into use on the “Bangjia†jack-up barge built by Nantong COSCO Shipyard. The system has obtained the product certification of American Bureau of Shipping (ABS), filling the domestic gap, marking Nantong Automation Company to make new breakthroughs in promoting the transformation and upgrading of professional technical services.
The deep submersible pump system is 3.218 meters long, 2 meters wide, 2.59 meters high, weighs 3900 kilograms, and has a flow rate of 100 cubic meters per hour. The submersible pump has a working depth of up to 26 meters. Its main function is to lower the hose attached to the winch and the submersible pump by rotating the winch after the platform leaves the sea. After the submersible pump is immersed in the water, the water pump is started to supply water to the platform. . In October 2012, the automation company undertook the deep submersible pump integration project of the “Bangjia†jack-up barge. Before the deep submersible pump system was monopolized by foreign manufacturers, there was no manufacturer with independent intellectual property rights in China. Based on extensive experience of foreign countries, the automation company's project team succeeded in developing for 8 months, so that the error precision of each key part of the whole system is controlled below millimeter level, and the product volume of the product developed under the same working conditions is the same. And weight is reduced by 1/3.
In order to ensure the technical safety of the deep submersible pump system, the automation company not only designed the deep submersible pump with the electromagnetic brake automatic braking system, but also designed the manual bolt parking to ensure the safety of the system to the utmost. In terms of system control, multiple circuit interlock protection functions are designed. At the same time, the project team carried out a movable improvement of the deep submersible pump. By installing a twist lock on the bottom of the winch, the whole system was easily disassembled, and the manufacturing price was reduced by 30% compared with the foreign similar products.
