Methods of jet pneumoautomatics with reference to devices of moving on an air pillow are considered. The local system constructed on the basis of methods of jet pneumoautomatics, for management of thickness of an air pillow is shown. In clause the opportunity of automatic removal of dusty air from a working zone of pneumotransport system is reflected. On the basis of hydro dynamical calculation parities for engineering calculations of values of
The article considers the model of granulometric
composition of foundry dust. We used the method of
particle size analysis, which is based on the dependence
between the size and the velocity of a body under the
action of gravitational or centrifugal forces.
Determination of granulometric composition of the given
sample of powder was made using the laser diffraction
method, implemented on a laser particle analyzer, Fritsch
NanoTec “ANALISETTE 22”. A model of dust particle
size distribution has been obtained
Methods of jet pneumatic automatics as applied (Pneumatic automation) to systems of transportation on an air pillow are considered. Use of methods pneumatic automation is shown at designing the flowing channels providing jet management on the basis of aero hydrodynamic effects. On the basis of hydro dynamical calculation parities for definition in engineering calculations of critical values of characteristics of flowing elements of the pneumoconveyor are determined. Time of transient of system of switching of air streams is determined
The model of identification of process of a dust con-tent of the air is submitted. It is shown, that in a work-ing zone of foundry shops the significant amount of a dust is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The dust is most dangerous to health of the working personnel and creates problems at clearing air. The model of structure of dusty air is received
The given developments are devoted to modeling of control systems by ecological safety of foundry manufacture. In a working zone of foundry shops except for a dust the significant amount of polluting substances is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The given dust is most dangerous to health of the working personnel and creates problems when clearing the air
The method of control of the amount of flow area of the supply nozzles in tape conveyor on a hovercraft is considered in the article. The local system that implements the principle of direct action to control the thickness of the air cushion is shown. Based on the hydrodynamic model, the formula for the engineering calculations of values of the moving devices are determined
