Efficient motor leader small make up to second-hand motor dismantling business first stock on the market is coming to an end. Recently, teardown business offer enthusiasm is not high, the motor overall quantity of goods is not much, dismantling workers will gradually returning, partial dismantling market quotient lunar twenty or so into official holiday mode. At present, the linyi market ordinary motor quotation is about 74 yuan/a supply of goods,Old strong magnetic, downstream demand and there is no obvious improvement, how to maintain according to need to pick up the goods, the early stage of the price is little change, old strong magnetic quotation is controlled in 89 yuan/kg, volume is not big. It is reported, linyi is the main market of domestic waste motor of retrieving and dismantling, but since August, due to the environmental policy requirements, the mainstream market shut down in succession, the old motor simple dismantling old prices remain steady weakening trend, in the old motor recycling market temporarily not clear.
▷从行业整体情况来看，废旧电机回收拆解正面临人工成本增高、利润下滑等问题。 Under this background, the old motor industry gradually spawned profiteering industry & ndash; —Motor renovation. Some manufacturers of waste brushless motor stator for special treatment, enameled wire around again, in the motor assembly; For surface retrofitting old magnetic steel pieces. In fact, magnetic magnetic steel piece is the key to keep the motor efficiency, the motor using the longer, the more demagnetization, the motor efficiency is lower, which means that the renovated motor efficiency is much less than the new motor. In addition, the renovated motor tend to overheating, in the process of using noise (Current sound)Great harm, and even the leakage, etc. ,.
for a long time, the old motor recycling market chaos, motor simple dismantling causes big waste of resources, renovated motor poured into the market, & other; A large number of production, consumption, a large number of abandoned & throughout; The traditional production and consumption patterns of social resources and the environment caused great damage. In environmental production at present, countries need through the development of circular economy, set up resource recycling system, to achieve the efficient use of resources. Therefore, developing and manufacturing is imperative.
motor efficient remanufacturing
as the inefficient stock motor by redesigning, methods of replacement parts, then made into high efficiency motor or applicable to the specific load and working condition of motor system energy saving.
cost, compared with the new products, remanufacturing product can save cost 50%, material saving 70%.
on energy efficiency, and then compared with the general conventional motor manufacturing efficient motor, comprehensive technical performance and protection grade can be increased, the efficiency compared with Y, YKK series products, 1 - can be improved10%.
on environmental protection and energy saving, and replacement of up to 10 million mw in the efficiency of using ordinary motor and remanufacturing into efficient motor, which can realize energy saving 3. 7 billion kilowatt-hours (4 of industrial total power consumption. About 7%), 5 recycling iron items. 50000 tons of silicon steel sheet. 6. 10000 tons.
on policy support, brushless motor manufacturing industry has been presented positive again, as early as 2005, 22 documents issued by the State Council has made clear that countries & other; Support for waste electromechanical products remanufacturing & throughout; , and at the same time, remanufacturing has been listed as the National Development and Reform Commission and other relevant departments jointly launched one of the four key areas of circular economy pilot work.
motor efficient remanufacturing methods varied, among them, the copper rotor motor remanufacturing has the very big advantage. Copper rotor motor remanufacturing has not changed the basic structure and the rotor outside of any other parts, but to replace aluminum rotor with copper rotor, maximum use of existing technology, equipment, technology, accessories and parts, etc. , make inefficient, energy saving, declared obsolete by formal decree of the state machine to meet the new requirements of energy efficiency (nationalGB18613 -2012 rules of grade 2 energy efficiency)The efficiency of the motor. Meanwhile, copper rotor motor can realize large-scale production, to solve the current remanufacturing pain points of motor can't mass production. Copper or will lead motor rotor motor manufacturing standards, motor remanufacturing development direction.
above all
motor efficient remanufacturing is of great significance, has broad market prospects, no matter from economic benefits, social benefits, and resource efficiency considerations are worth promoting. In the implementation of industrial development, green production, green waste motor efficient remanufacturing is a good way.
