air blower concept: The air blower is our country to the gas loading and the gas transfer machinery custom abbreviation, usually said the air blower includes the ventilator, the air blower, the wind-driven generator.The gas loading and the gas transfer machinery are transform the revolving mechanical energy into the gas pressure energy and the kinetic energy, and gas transfer machinery.
The air blower main structure part is the impeller, the cabinet, the tuyere, the support, the electrical machinery, the belt pulley, the shaft coupling, the damper, the biography moving parts (bearing) and so on.
The air blower including the ventilator, the turbo, the Luo tribulus air blower and the turbocompressor, the detailed division including the centrifugal gas compressor, the axial-flow compressor, the centrifugal forced draught fan, the Luo tribulus air blower, the centrifugal ventilator, the axis flows the type ventilator and Ye the air blower and so on 7 big kinds.
According to the air blower mechanism difference, has the leaf blade type air blower and Rong Jishi the air blower two kind of types.The leaf blade type is through impeller revolving the energy transfer for the gas; The volume type is through the work room volume periodicity change the energy transfer for the gas.Two kind of type air blowers have the different pattern separately.
The leaf blade type air blower including the centrifugal-type air blower, the axis flows the type air blower and the interflow type air blower, the volume type air blower including toward the multiple air blower and the rotation type air blower.
Air blower principle of work: Ventilator principle of work and turbocompressor basic same, only is because the gas discharge rate is low, the pressure variation is not big, does not need to consider generally the gas specific volume the change, namely takes the gas incompressible flow body processing.
Air blower examination standard: Loses the air blower key to the air conditioning ventilation system matches the energy consumption, constructs the energy conservation extremely essential part.According to the national air conditioning equipment quality surveillance test center many year air blower examination indicated very many amount of wind cannot meet the design requirements under the fixed operating mode.The air blower examination basis standard mainly has GB/T 1236-2000 "Industry Ventilator Standardization Air flue To carry on Performance test", JB/T 9068-1999 "Front Multi-Wing Centrifugal fan", JB/T 8932-1999 "Wind Engine case", GB 10080-2001 "Air conditioning Ventilator Safety requirements", JB/T 9069-2000 "Roof Ventilator", GB 10178-2006 "Industry Ventilator Eifld performance Experiment", JB/T 10281-2001 "Fire prevention Discharges fume Ventilator Engineering factor", GB/T 13933-2008 "Small Throughflow Ventilator", JB/T 6411-1992 "Warmly Passes, Spatial Transfer Axis Circulation Air blower", JB/T 7258-2006 "General-utility Centrifugal forced draught fan", JB/T 10562-2006 "General-utility Axis Circulation Air blower Engineering factor", JB/T 10563-2006 "general-utility centrifugalismThe ventilator engineering factor", GB 19761-2009 "Ventilates Function Effect Limitation value And Energy conservation Appraisal Value", JG/T 259-2009 "Jet flow Induction Unit", JB/T 7221-1994 "Unit Type Air conditioning Unit with Double Enters Wind Centrifugal fan", JB/T 8932-1999 "Wind Engine case" and so on, the examination project main amount of wind, the wind pressure, the power input, the rotational speed, the firing distance, can the effect and so on.
The air blower walkaway and the air blower vibrate the examination mainly based on GB/T 2888-2008 "Air blower And Luo Tribulus Air blower Noise measurement Method", JB/T 8690-1998 "Industry Ventilator Noise Limiting value", JB/T 8689-1998 "Ventilator Vibrate Examination And Limit", GB 9068-1988 "Heating Ventilate with Air conditioning Equipment Noise Accoustical power rate Determination - Project Law", GB/T 3767-1996 "Above Acoustics Sound pressure Law Determination Noise source Accoustical power rate Level Reflecting surface Approximate Free field Project Law".
The air blower uses when matters needing attention:
1st, air blower bearing temperature normal when for ≤70℃, once if elevates 70℃, has the electric control to be supposed (to meet) reports to the police.This time should search the reason, first inspects the cooling water is whether normal? The bearing oil level is whether normal?
2nd, the air blower drives, in the parking or the generating process, if the discovery freak occurrence should carry on the inspection immediately.
3rd, the air blower moves for the first time for a month, should renew the replacement lubricating oil (fat).
