Recently, the major national scientific and technological achievements into the project in Suzhou Marine Power Systems, Inc.'s commitment to "ship with a controllable pitch type rudder propellers device technology and manufacturing" project by the Department of Finance, Jiangsu Province, Jiangsu Province Economic and Information Technology Commission of the Organization experts acceptance.
In the acceptance process, after listening to the reports, site visits, access to information, questions and comments and other procedures, the inspection team of experts agreed that the project is complete acceptance documents, detailed data, reaching project goals and objectives and responsibility, agreed to its acceptance.
Experts believe that the Soviet ship powered down together marine controllable pitch type rudder propellers device technology and manufacturing project led to the adjustment and upgrading of special marine propeller of product structure, technology as a whole in the international advanced level, with broad market prospects.
The total investment of the project is 73.568 million yuan. The new production plant and R&D building have been built. 12 sets of high-end CNC machine tools and equipment have been purchased. The production process equipment has been optimized and modified, and the adjustable pitch type full-rotation rudder propeller device has been built. technology and manufacturing production lines, the annual output of 48 is formed (set) adjustable pitch-type rudder propellers product. During the project implementation period, 18 patents were applied (including 9 invention patents), and 12 patents were granted (including 5 invention patents).
Qin Yan, deputy director of the Jiangsu Provincial Economic and Information Committee and director of the Provincial Defense Science and Technology Office, fully affirmed the company's innovation work in recent years at the acceptance review meeting, and at the same time strengthened cooperation with research institutes (schools) in the future. The technical content of the products, actively participate in the formulation of industry standards, drive the overall technological progress of the industry, strengthen the integration of capital market resources, and expand the scale of enterprises.

Closed Cooling Tower

Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.

First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.

Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.

Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.

To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
