On October 18, 2012, the Guangdong Provincial Marine Supervisor's Guangdong Provincial Corps hosted a factory inspection and acceptance meeting for the 1000-ton provincial-level rights-enforcement special sea surveillance ship integrated by Zhonggao Diesel Heavy Industry Co., Ltd., and ten experts on the medium-high diesel heavy machinery. The production, manufacturing and inspection of the main equipment were investigated in detail, and the relevant technical documents and quality inspection records were strictly examined. The results of the delivery test of the rig were carefully examined, and the two MANs manufactured by Zhonggao Diesel Heavy Industries were finally identified. The 8L27/38 marine surveillance ship's main engine acceptance was qualified, which represented the successful completion of the first high-level sea surveillance ship propulsion system project for the first time.
The medium and high manufacturing sea surveillance ship host passed the acceptance
When it comes to sea surveillance vessels, everyone is no stranger. In the recent Huangyan Island incident and the Diaoyu Islands incident, the sea surveillance vessels representing China's maritime rights and interests frequently appeared in the international perspective. "Sea surveillance ship" is the full name of "China Maritime Supervision Law Enforcement Ship". It is the representative and professional team of China's marine law enforcement. It mainly conducts cruise surveillance of China's sea areas; it violates China's maritime rights and interests, illegally uses sea areas, damages the marine environment and resources, and destroys the sea. Investigation, evidence collection and handling of illegal activities such as public facilities and disturbance of sea order; emergency monitoring, monitoring and warning of major events such as marine pollution; taking into account marine resource exploration and environmental monitoring. On November 8, 2011, Zhonggao Diesel Heavy Industry Co., Ltd. and China's Haijian Guangdong Provincial Corps signed three agreement agreements for the maintenance of shipowners' propulsion system. In order to do a good job in this sea surveillance ship project, the organization is highly organized, designed, technical, manufacturing and quality. Strict requirements for control and other aspects are implemented with military standards.
1. Nearly 100% of parts are imported, and the number of spare parts is greatly increased.
Except that the body is designated by a large domestic marine engine factory, the rest of the parts are imported from Europe, America and South Korea. This will undoubtedly greatly increase the manufacturing cost, but in order to ensure the strict use performance requirements of the sea surveillance ship mainframe, the main components of the main engine such as crankshaft, piston, connecting rod, supercharger, governor, bearing bush and even seal ring are all from High-quality suppliers such as Germany, the United States, Austria, and South Korea purchase to ensure the quality of high-quality parts of diesel engines. In addition to the regular spare parts, the customer has added a large number of spare parts, including consumable parts such as injectors, piston rings, bushings, air valves, seals and other parts, which are also required to be imported.
2. The host adds additional configuration and makes multiple improvements.
A number of configurations and improvements have been added to the main unit, such as adding gearbox cooling water connections to facilitate gearbox cooling; adding supercharger return pipe thermometers and sensors, oil and high temperature water thermometers to facilitate user temperature and high temperature water The temperature is closely monitored; the crankcase vent tube adds a water drain device to prevent backflow of water into the body.
3. Complete the power package upgrade and work closely with the design institute
For the first time, the high-altitude diesel engine heavy-duty engineering adopted the power package integration technology, which integrated the power system and peripheral system of the gear box, propeller, shafting, etc., and cooperated with the supporting factory and the design institute. The result was obtained by the design institute. Highly praised. At the same time, it also means that the medium-high diesel heavy machine has upgraded from a single mainframe to the power integration technology, and once again demonstrated the independent R&D design capability of the medium-high diesel heavy machine based on MAN technology.
4. Increased delivery inspections and increased number of pilot projects
The delivery test is a key link to evaluate whether the various performance indicators of the diesel engine meet the requirements of use, and is also a comprehensive test of the quality and assembly technology of diesel engine parts. The medium and high diesel engine is the integrated design unit of the main engine and the power package. Combined with the special use requirements of the sea surveillance ship, the additional security items, propeller matching characteristics, load limiting characteristics and other test contents have been added, and the load characteristic evaluation time has also doubled. These have increased the difficulty of diesel delivery trials.
After the first batch of sea surveillance ship mainframes were successfully delivered, Zhonggao Diesel Heavy Industry Co., Ltd. was in the process of developing and manufacturing the next batch of sea surveillance mainframes and power package integration schemes, and strived to make more contributions to China's marine rights protection.
