The paper analyzes the determination method of the curvature radius at bending part of pipy belt conveyor,which provides a theoretic basis for the design of the line arrangement of the bending part of the pipy belt conveyor.
Practice shows that a key to tapping potentialities and reform of the railway transport development system for ultra-deep opencast mines is improving the continuous running time of electric locomotive on upline, prolonging the service life of rail and wheel , remoulding old equipment , improving the rail line configuration , tightening control of equipment maintenance, especially introducing the combined transport development system instead of the single transport development system.
It is a key task to reasonably arrange the water conveyance line, therefore, we compared three kinds of line arrangements, and finally selected the optimum method, consider many factors, e.g., reasonable design, convenient construction, perfect management, environment protection, and decreasing the loss of power resources.
Based on design and running practice of suspension tubular belt conveyor in our country, present paper describes the working principle, technical performance and specific features in route layout of several such conveyors being installed or under trial run.
With the example of an aircushioned belt conveyorsystem, used at the Zhengzhou second flour plant for wheat transportation to reduce dusting, this paper pres-ents the system layout, sealing cover and air chamber of the conveyor and the layout and size of the apertures.
There were tube banks with in-line arrangement for small tube pitch ratio.
We prove that the complement of a real affine line arrangement inC2 is homotopy equivalent to the canonical 2-complex associated with Randell's presentation of the fundamental group.
An experimental investigation has been conducted for exploring a possibility to improve the heat transfer of tube banks of in-line arrangement, in which the first cylinder was roughened with pyramids.
Line by line arrangement results in an orthopan projection, the orthopan tomoscintigram.
For a three-row tube bundle in an in-line arrangement without winglets, the heat transfer and the pressure loss were 72% and 210% higher, respectively, than for a multichannel test core without any built-in tube or winglet.
