The fluid vacuum and ventilation systems (liquid or gas) local exhaust ventilation and fluid transport loaded chip dust

 fluid vacuum and ventilation systems

The suction or ventilation is produced by a vacuum generated by a pump or turbine propeller fan. The suction velocity must be sufficient to perform particle transport, that we must aspire, or ventilate the area with sufficient capacity meeting the standards.

In the case of a vacuum for carrying particles, the conveying speed is calculated in relation to the speed of sedimentation . We seek a maximum speed in the ducts, and the limit is imposed by the vacuum generated by the turbine.

sedimentation velocity and transportation calculation

The suction speed and therefore transport of dust, chips or other materials, is simply calculated using this interface. Suffice it then ensure that this minimum requirement is met. For this, the pump or fan of aspiration, should be strong enough to balance the the head loss in the extraction system. A calculation of losses, in accordance with the flow rate of minimum suction must be made.

If one wishes to make the propeller axial fan, generating pressure balancing the pressure drop at the desired speed we can use the software to design propellers and fans, héliciel.

In cases where ventilation is intended to renew, or filter, the air in a volume defined, lThe speed is limited by the noise and it meets standards according to local.

To find a good compromise between the purchase price, installation, operation, pumping, roughness, trade stock, An interface to aid sizing the ventilation ducts, or hydraulic, is integrated into mecaflux.

 Ventilation ductwork sizing diameter suction following recommended speed

The interface for sizing the ducts, scans a selected list of pipes and reports the most relevant choices of energy savings and installation costs according to pressure losses caused according the imposed flow..The diagnosis is only fair, and the choice may be different, depending on the strategy of amortization or operating life expected..The interesting point is the evolution of the pressure drop as a function of diameter. The noise being related to the speed, max speed according to the type of space is given.

 

lthe energy consumed by the pump and the efficiency of the vacuum are related:

In Mecaflux standard:

Parameters basics of power 'aspirations are easily found in the pump / turbine systems interface after a calculation of losses.
