From January to July, the city's above-scale shipbuilding industry achieved an output value of 50.255 billion yuan, an increase of 23.8%, an increase of 10.3 percentage points higher than the city's average.
Since the beginning of this year, under the current unclear external economic environment, Nantong shipbuilding enterprises have also faced many problems such as delaying the receipt of goods by ship supporting enterprises, lack of continuity of orders, and falling ship prices. However, the city's leading marine engineering leading enterprises adjust their technical direction according to market demand, identify the market positioning, work hard on product structure, seek differentiated competitive advantages, and make their own characteristics. E.g:
Rongsheng Heavy Industry currently ranks sixth in the world in terms of hand-held orders and second in the country. This year, it signed four VLOCs with a total of 1.6 million deadweight tons, which is far ahead of the global volume in the second quarter and has become the leader of domestic civil shipbuilding enterprises.
Among the several ship types that COSCO Kawasaki has built in batches this year, two ships with complete independent intellectual property rights have been completed, and 13000 TEU container ship, 6200 car wheel ro-ro ship, LNG ship, etc. have been developed for the market. , "point" ship, hand-held orders have been scheduled for the second half of 2012;
COSCO Shipyard seized the favorable opportunity of active trading in the offshore market, decisively entered the offshore market and gradually entered the harvest stage. It is now the world's most advanced ultra-deep water cylindrical semi-submersible drilling platform SEVAN650 and full-power multi-function Self-elevating workover platform for delivery preparation;
Xiaolong Heavy Industries has also gradually transformed into marine engineering, and has formed partnerships with Fortune 500 companies such as GM, Hyundai Heavy Industries, Singapore Keppel and Finnish MacGregor;
Hantong Heavy Industry Co., Ltd. is based on various types of ships and marine projects of 50,000 to 80,000 tons and manufactures 57,000 tons of bulk carriers, which avoids the “hot fight†with large shipyards and bypasses competition with similar shipyards.
High Speed Door Motor And Control Box
Our company have German SEW Motor, Japan Mitsubishi Controller. Our own brand Hofic servo motor and controller. Chinese famous brand SEJ motor and Holip controller.
About our German SEW Motor and Japan Mitsubishi Controller: It is easy to find the ideal energy-efficient motor for your application at SEW. The series has a suitable design in its range for the globally applicable efficiency classes. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimised built-in encoders ultimately complement the motor range. Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range: Cost-optimised built-in encoders integrated into the motor. Motors for efficiency classes IE1 to IE4.Compact design saves space and costs. Future-proof, also as regards environmental protection (standards). Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes.
About servo High Speed Door Servo Control System: Our rolling gate servo control system is suitable for high speed and high usage soft and hard rolling gate. The whole system is in a small and light package, it has high torque and high operating speed, lower noise, high reliability, smooth and soft operating curves, it`s suitable for high speed and usage environment. The rolling curtain can be controlled by pull switch, push button, Bluetooth, ground radar, ground magnetic sensors. Operating Speed: 1M/s; Operating Width: ＜16 ㎡; Daily operating time: ＞2000 time; Rated voltage: 220v; Rated Output: 0.75 KW/1.5KW.
The system can operated via: 1) control box; 2) inching electronic control; 3) continuous automatic operation; 4) emergency stop; 5) single side operation box; 6) time delay; 7) ground radar and/or magnetic sensors. Please refer to Wiring Terminal for eternal connections.
System has fuse/safety wire shutdown switch for three-phase power protection, fuse/safety wire for operating circuit protection, and temperature sensing relay for motor protection.
Stroke Controller utilizes absolute value encoder. Connect the absolute value encoder and reducer via encoder`s axle, and fix the wings on to the reducer, than insert the aviation plug into plug receptacle.
The mounting screw for the control box must inspect regularly to prevent screw been getting loose and falling off. Check the internal and external wirings. Check and change the oil for the redactor on regular basis.
Precision: The system use Full closed-loop servo control and Double Encoder design. This is to ensure long operating life and to prevent overshooting during operating.
Stability: The system utilizes integrated design concept, in order to simplify internal wiring and prevent any function caused by wiring and terminal connections.
High Speed: Motor max speed is 2500 rpm; door max operating speed is 2 m/s.
Smooth: The torque servo system can adjust torque to the load automatically, and its speed curve mode step less speed regulating to ensure a smooth operation.
About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.
