给煤机 coal feeder(中文2800字,英文2400字)
给煤设备是煤矿生产系统的主要设备之一,给煤设备的可靠性,特别是关键咽喉部位给煤设备的可靠性,直接影响整个生产系统的正常运行。目前,我国煤矿使用的给煤设备主要是往复式给煤机和电振给煤机,近年来,电振式给煤机发展较快,已形成系列化和标准化;而往复式给煤机自20世纪60年代定型后,系列的改进和扩大工作一直没有进行。随着煤炭工业的迅猛发展,煤矿井型也在不断扩大,现有的往复式给煤机已不再能满足煤矿生产系统的选型要求。正是基于这个原因,我们在对给煤机使用情况大量调研的基础上,研制了800t/h、1000t/h、1500t/h、2000t/h的大型往复式给煤机,往复式给煤机最早研制于20世纪60年代初,70年代,在NGW基础上,更换了驱动装置,改为K系列,并一直沿用至今。K系列给煤机共有五种型号:K-0、K-1、K-2、K-3、K-4,其中K-4生产能力最大,但也只有590t/h。国外给煤机发展状况也与国内大相径庭,并没有更高的技术含量,但价格却是国内同类产品的4-5倍。

Equipment of the coal mine production system is one of the main equipment, the reliability of it, in particular parts of the throat is the key to the reliability of such  equipment, will directly affect the normal operation of production systems. At present, China's coal mines to the coal used primarily is reciprocating coal feeder and coal to power vibration machine, In recent years, the electric machine vibration to the development of coal faster serialization and standardization has been formed; and reciprocating coal feeder 60 from the 20th century's stereotypes, the series of improvement and expansion of the work has been carried out. With the rapid development of the coal industry, coal type is also growing well, the existing reciprocating coal feeder Coal is no longer able to meet the selection requirements of production systems. It is precisely for this reason that,We are on the basis of the coal feeder for the use of a large number of studies,development of the large-scale reciprocating coal feeder, include 800t / h, 1000t / h, 1500t / h, 2000t / h, Reciprocating the earliest development of coal feeder 60 in the early 20th century, 70 years, based on the NGW, the replacement of the drive into K series, and are still in use. Reciprocating coal feeder of K series has a total of five models: K-0, K-1, K-2, K-3, K-4, K-4 is the largest production capacity, but still only 590t / h. The development of Reciprocating coal feeder has no different between abroad and national, it doesn’t have a higher technological content, but the price is 4 to 5 times in similar products.
