calculation of air to combat the excessive heat

Calculation of ventilation to combat the excessive heat produced by two or three periods. Most notable the first period - summer - when the outside temperature is above - (-10 В° C. The calculation is for an outside temperature of the warm period of the year on the parameters A (SNIP IT. 7-62). If the supply air enters through the open... read more >>


Dust control by removing it with suction air, as is known, is called aspiration.

Aspiration distinguish two cases kapsyulyatsii hearth dust:

a) full shelter in a solid casing, having no other openings, except techek;
b) incomplete cover, when the housings have slots and holes.

Automation and lock

Automation of ventilation systems - a relatively young field of technology. Until recently, most ventilation systems are not automated and can not be blocked from processing equipment. This does not apply to air conditioning systems, which are generally impossible without automation.

In recent years, automation and lock are increasingly... read more >>

ball mill

Ball mill for mixing and grinding the paint is a rotating drum with a hermetically closed the hatch through which you are loading and unloading. Full cover mills is impossible, since you have to maintain it at the top, bottom and middle positions of the hatch.

Load of dry pigment and binder are made by filling the top position of the... read more >>

basic principle of ventilation

The basic principle of ventilation reads: "Give the air in the clean zone and benefit from the dirty." Consequently, when general ventilation particularly essential to determine where they will "clean" and "dirty" zone.

The allocation of dust (especially large), heavy gas fumes in the absence of convection currents "dirty" zone will... read more >>

blasting compressed air corps

Blowing compressed air corps is sometimes made in the cabinet-type shelters with an inclined front wall, performed by Plexiglas. Opening in the shelter is the minimum size of 400x400 mm. Calculated air velocity in a section of the opening and leaks must be at least 2 m / sec.

Apparatus in which the backfilled dusty materials (powdered... read more >>

calculation method, developed MIOTom

In addition to fashion Promstroyproject, now sometimes use the method of calculation, developed MIOTom. This method is based on a formula derived M. Baranov, equally suitable for conventional and inverted suction.

The toxicity of harmful emissions into account the so-called height of the spectrum to the hazards (high range flow). More... read more >>
