SOLVING THE PROBLEM OF IMPORT SUBSTITUTION IN THE EXAMPLE OF THE COMPANY KRACHT HIGH PRESSURE PUMP USED IN COAL MINES Korotkov A.N. , D.Sc.

Gorbatchev, 28 Vesennaya st., Kemerovo, 650000, Russian Federation Abstract There is a problem of restoration and replacement of worn parts imported components and assemblies, which are separate parts, as a rule, do not come, and only blocks replaced. To solve the problem analyzed technology for manufacturing key components gear pump for possible recovery or production. For this purpose, identified materials making up the drive shaft and the gear, the end seal plates, bushings. Established kind of hardening of details; recommendations on the production of repair kits to high-pressure gear pump. This approach can significantly reduce the costs of repair work and maintenance of gear pumps and thereby implements the concept of import substitution. Keywords High-pressure pumps, repair and restoration of details of pumps, gear shaft, sleeve, end seal, import substitution, macrostructure, microstructure
