Mechanical Bar Screen
Mechanical Bar Screen is provided with several special-shaped teeth which are assembled on the teeth axis based on certain ordering, forming the sealed teeth chain. The lower part is installed in the water inlet. If the chain wheel rotates directionally with even speed, the whole rake chain will move accordingly. Under such circumstance, the solid sundries attached on the tooth will be separated from liquid and the fluid will low away through the gap. When rake chain arrives at its upper end, each group of rakes will carry on self cleaning by dropping out most of the solid material under gravity and guideline rail, while the rest of the solid will be tidied clean by back running brush.The whole process is carried out continuously and automatically so as to achieve the goal of solid-liquid separation.

Recently, the topic of not competitive domestic diesel engines has been heated up in the industry. It is undeniable that the high cost of importing and supporting high-end components is an important reason for this problem. Under the current competitive pressure of foreign diesel engines hitting low-priced brands, it has become the consensus of all parties to reduce the cost of domestic diesel engines as soon as possible. Recently, the China Shipbuilding Engineering Society convened a number of experts from the industry to hold a symposium on diesel engine supporting technology development for the development of private diesel engine supporting enterprises represented by Suzhou Liqiang Machinery Manufacturing Co., Ltd. Experts actively offered suggestions and hoped that the domestic diesel engine core supporting enterprises could Quickly grow bigger and stronger. This is the first time that the Shipbuilding Engineering Society has held a special symposium for private supporting enterprises. What kind of enterprise is Liqiang Machinery, which makes many experts in the industry have high hopes for it?
Opportunity - Specialized Productivity Machinery is a professional manufacturer of high-power low-speed diesel engine core components. Its products are specially designed for Mann and Wärtsilä high-power low-speed diesel engines with a cylinder diameter of 350-980 mm. The company broke ground in October 2008. , trial production in April 2010. Zhao Xianhong, chairman of the company, said that under the trend of shifting the focus of the world's shipbuilding industry to China, the demand for diesel engines in the domestic market will rise steadily, and the demand for diesel engine core components will also increase, and currently there is no scale in China. Specialized diesel engine core parts manufacturing enterprises. The eight major diesel engines, including the cylinder head, piston rod, crosshead, and base, are currently produced by the diesel engine factory, and some can only rely on imports. By itself, when the diesel engine production capacity is small, the products can still meet the demand. Now, with the expansion of production capacity, the supporting capacity of the diesel engine plant is generally unable to keep up, and it is far from meeting the market demand; the import is expensive, the cycle is difficult to guarantee, and the technology Supply is subject to foreign countries. Therefore, the establishment of professional manufacturers of diesel engine parts will change the situation of relying entirely or not on foreign imports.
It is understood that Korean shipbuilding products have achieved socialization, diesel engine manufacturers focus on assembly and commissioning, and parts and components companies focus on producing parts, achieving specialized production, large-scale operation, high production efficiency and cost. low. Liqiang Machinery saw the potential of specialized production and decided to enter this field after the outbreak of the international financial crisis.
Challenge - Software still needs to be upgraded Zhao Xianhong said: "Our goal is to become China's first, world-class professional high-power diesel engine core parts manufacturing enterprise." To this end, they attach great importance to hardware investment. At present, Liqiang Machinery has completed the first phase of the project covering an area of ​​61,500 square meters in Xinzhuang Industrial Park of Changshu City. Among them, the production workshop covers an area of ​​34,800 square meters. The plant is tall and spacious, with first-class facilities and advanced CNC equipment for precision machining. The investment amount exceeds 250 million yuan. It is particularly worth mentioning that some of its high-precision processing equipments are unique among domestic diesel engine supporting enterprises, even if compared with foreign diesel engine parts manufacturers.
Hardware can be bought for money, and the promotion of "software" such as technology, talent and management is not a day's work. Many experts have expressed their ardent hopes for the development of Liqiang Machinery, and also put forward their pertinent opinions and suggestions on their shortcomings: First, I hope that enterprises can recruit talents and give full play to existing hardware functions. Secondly, practical skills for existing employees. Training, strengthening management; finally, often communicate with experts from organizations and institutions including the China Shipbuilding Society to listen to their opinions.
Ways: All parties work together to strengthen the supporting experts. In the discussion with the relevant leaders of Liqiang Machinery, it is pointed out that to catch up with Japan and South Korea, the efforts of relying on the strong machinery alone are not enough. On the one hand, if the quality of the blanks is unqualified, the processing is good, and the quality of the products is difficult to guarantee; on the other hand, even if the quality is passed, if the diesel engine factory continues to adopt the "small but complete" mode, its products will be difficult to open the market. Therefore, to strengthen the supporting, it requires the concerted efforts of all parties in the industry, adhere to the road of specialized production and large-scale operation, and constantly improve the management and technical level.
At present, China's diesel engine two-wheel supporting capacity is not strong, and the market potential is large. The relevant person in charge of the China Shipbuilding Society believes that in this field, private enterprises are a force that cannot be ignored, and the role of private enterprises should be emphasized. Therefore, the Society has specially convened expert consultations to provide technical services for the development of private enterprises so that they can grow rapidly. The person said that if the domestic diesel engine core supporting capacity has made a breakthrough, it is not only a blessing for the diesel engine factory, but also a blessing for the Chinese shipbuilding industry.
