The value of equipment purchase

Second V ten = / c4r, in many of the features the same items, select the most cost-effective to buy the lowest cost. Such as: similar test wave, two factories produce the same drawing, the test is identical in function, but the production costs are lower than Yichang Jia Chang, the Jiachang oscilloscope production of high value than Yichang,[link widoczny dla zalogowanych], to be elected Share Jia Chang's. Third V ten ten ten = F / v ten, the function of several types of equipment and costs are different, the need for further analysis, a higher cost of equipment, and functions to meet a higher degree, then its value is high, you can choose to purchase of objects. If, after design improvements, a combination of manufacturing machine tools, can be turning, milling, drilling and other processing operations, because of the increased functionality, need to increase the number of components, the cost has increased, but there is a huge increase function, then the value of the machine also increased. Ten forty-V = F / C: decreased levels of certain device features, but its lower cost, its value is higher, which in September 2001 South Africa 3 Fengtan Hydroelectric Power Plant Unit 2 cause leakage of water guide analysis and improvement measures for large wind Beach hydroelectric power plant and Zhou Zhou Chuan Feng Hydropower Plant under the waves Abstract Turbine unit of water bodies caused by leakage can not be removed after the shutdown of air curtains and a series of issues, from the device structure, materials so analyze the causes and propose effective solutions for technological transformation. Keywords Analysis of leakage water guide technological transformation of the western Hunan Province, Feng Yuan River Hydropower Plant is located in the lower reaches of tributaries shui, in Yongshun, Guzhang, the lot at the junction of three counties Yuanling Yuanling County,[link widoczny dla zalogowanych], the county seat away from the Yuanling 45km. Control of the drainage area above the dam site is 17500km2, accounting for 95.1% of watershed area shui. The mean annual runoff of 15.9 billion m3, design head is 73m, maximum head of 91m, minimum head 54m, design flow t60m ~ / s, a total installed 4. Unit capacity of 100MW of vertical Francis turbine generator set,[link widoczny dla zalogowanych], turbine model HL702 an LJ a 410. Designed annual power generation capacity 20.4l million kW · h. Annual utilization hours 5200h. May 1978 1 unit (Unit 2) put into operation, has run for 20 years, is now 4 sets of turbine guide apparatus are varying degrees of leakage, resulting in open units, down a long time, stopping the brake can not be timely completed removal of damper, in particular the purchase of objects can be pushed to be elected. For example: the first steel mill in Tangshan Iron and Steel Company's net Central station, is based on two refining equipment, for the four converter bearing cooling fan (two refining furnaces seat each for the 30t, a smelting furnace seat for each 6t), there is a large horse-drawn cart, with extra features. In order to eliminate redundant functions, value engineering group ring pump station on the net value analysis and calculation, with 6SH_-9 pump instead of 8S} {_ a 6-pump,[link widoczny dla zalogowanych], replace the 100kW motor with 40kW motor, the test equipment required to function After the transformation to run 1 year 2 months, saving 780,000 kW · h, sections owned 608,400 yuan. Ten Ten = F V V / C: This approach is in improving the function while the cost of which had been reduced, the value of such equipment will be greatly improved. Such as: a drill press, power through the innovative flexible metal bearings replaced plastic tile, the unit 2 can hardly be removed dampers, larger brake ring generator load, the wear increases, 4 units have been found to have different brake ring degree of crack and seriously endanger the safe operation of the unit. Large amount of leakage water guide, causing gas consumption increased when phase modulation, phase modulation of the normal unit operation, also causing a lot of waste of water resources, directly affect the plant's economic benefits. l Analysis of leakage water guide 4 hydroelectric generating set as 70 product lines, after 20 years of operation, and by the time the design, technology, materials and production abilities of the limitations of hydro-generating unit went into the aging stage, equipment in recent years has exposed many flaws. Units from the original design drawings and the actual operation situation, the turbine guide apparatus serious leakage, mainly the long duration of the aging equipment in service, after only a few drill bit can be drilled, and the reduction in the cost than the original, the improved drilling, have greatly improved the value should be for the purchase of objects. In summary, value engineering as a scientific technical and economic method, which the people use their experience from the original purchase of equipment, and guide to the features and costs from the comprehensive quantitative analysis of a unified staff, the concept of value, and ultimately determine the highest value of equipment - most people say is worth buying the equipment, to avoid the subjectivity and blindness purchase of equipment. And to purchase equipment to enhance the value of the direction. As long as we purchase materials widely used in value engineering method, bound to be a huge economic benefits.
