Substantive provisions of experimental researches

Mapping out of experiments allows, using the minimum number of experiences to select those conditions which optimise target parametres. Thus it is necessary to investigate influence on transportation process first of all the most essential factors, not complicating and without that a labour-consuming method eksperimentirovanija and developments of experimental data [6, 113].

The purpose of carrying out of laboratory experimental researches is definition of character of influence of an offered design aeratsionnogo the device representing pipes, executed on concentric circles with vvarennymi in the bottom part and the nozzles bent under certain corners, and technological operating modes of the pneumochamber pump on process psevdoozhizhenija a material.

Research problems are definition of the most rational design data of considered devices, optimisation of modes of transportation of a material by means of the pneumochamber pump supplied multisoplovym aeratsionnym with the device for achievement of peak efficiency of process psevdoozhizhenija and discharge of a material. For the decision of tasks in view of an experimental research on material transportation by the pneumochamber pump supplied with the offered design multisoplovogo aeratsionnogo of the device, following stages of work are realised:

1. Working out and manufacturing of experimental installation of the pneumochamber pump supplied with the offered design multisoplovogo aeratsionnogo of the device;

2. A substantiation and a choice of constructive and technological parametres of the pump which is exposed to change and the supervisory control at carrying out of experimental researches;

3. A choice of criteria of an estimation of efficiency of process of discharge of the pneumochamber pump;

4. A choice of the plan of carrying out of multifactorial experiment, an establishment of levels and spacings of a variation of the factors influencing functions of the response;

5. Selection of the measuring equipment and measurement techniques;

6. Experiment realisation, the analysis of the received results.

The work order on experimental researches of process of transportation of cement by means of the pneumochamber pump is presented in the form of algorithm in drawing 3.1.
