Wuhan Shipbuilding 400,000 tons ore ship supporting anchor winch successfully passed ship inspection and inspection

It is reported that the anchoring machine for Wuhan Shipyard's 400,000-ton ore sand ship has successfully passed the ship inspection and inspection of DNV GL and China Classification Society (CCS). The anchoring machine includes two K122U3 windlass and ten 315KN systems. Mooring winch.

On the basis of optimizing the cost of 319,000 tons of VLCC anchor winch, Wuhan Shipbuilding continued to carry out “design optimization, weight reduction and cost reduction” as the main content of the 400,000-ton series marine anchor winch in accordance with the first-class requirements of the international standard. Improve quality and efficiency.
From the aspects of structural design and material selection, the structure optimization of the anchoring machine is comprehensively carried out, and the product structure is optimized to achieve the optimal product structure; the work of “weight reduction and cost reduction” is carried out in terms of equipment weight and layout size, and passed in the design process. Three-dimensional design, simulation and other means to analyze the working conditions of the anchoring machine, gear life and contact frequency on different shafts, drum cylinder load and loading mode, spindle load and force fulcrum, etc., continuously optimize the wall thickness of the cylinder, Gear width and thickness dimensions, spindle material, base, single bracket, anchor sprocket material thickness, brake hinge arrangement and material of the parts.
At the same time, combined with the refinement requirements of the process, refine the processing steps, accurately calculate the processing time of each process, optimize the machining process to reduce the blank amount of parts, and carry out centralized procurement of similar parts, effectively reducing the procurement cost of parts and ensuring optimal product structure. The weight is reduced by 10%, and the goal of “weight reduction and cost reduction” of the anchoring machine is realized.

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.
