Foreword
This standard is GB/T 3235-1999 "Basic fan type, size parameters and characteristics," the amendment.
This standard compared with GB/T 3235-1999, the main technical content amended as follows.
--- Original standard Chapter 2, "Normative references" to "normative references", and cited the effectiveness of standards was confirmed.
--- Expanding the scope of the 'for general purposes centrifugal and axial fan "to" apply except jet ventilation
Industrial machines, cross-flow fan and fan household or similar use devices other than centrifugal and axial flow fan. "
--- All the original standard "fan total pressure" to "Fan pressure"; "total pressure within the efficiency" to "fan efficiency."
--- Fan pressure category "see definition in JB/T 2977" to "see definition GB/T 19075".
--- Original standard 3.5.2 "Connecting and structure type axial fan and gear" to "gear type axial fan
And structure. "
--- Original standard 5.1 "unless otherwise specified in the contract, the general purpose of the fan to draw air under standard conditions." Read
"Unless the sample according to the provisions of the contract or as otherwise provided, the general fan performance curve performance parameters should be converted to the standard intake state
Next draw. "
--- Original standard 5.5 "fan aerodynamic performance test according to GB/T 1236 implementation of" the words "fan styling products
Plant performance testing and new product (model, prototype) Performance test should be performed in accordance with GB/T 1236. Fan site of the product
Can test should be performed in accordance with GB/T 10178. "
--- This standard increases the fan lubrication, bearing type fan, fan support and fan air intake mode methods;
--- The standard increases in Table 2;
--- This standard increased product field performance test performance curve section;
--- This standard increases the performance curve plotted dimensionless parameters.
From the date of implementation of this standard instead of GB/T 3235-1999.
The standard proposed by China Machinery Industry Federation.
This standard by the National Standardization Technical Committee fan (SAC/TC187) centralized.
This standard was drafted. Shenyang Blower Works (Group) Co., Ltd., Tianjin Blower Factory.
The main drafters of this standard. PAPTY, Zhao school record.
This standard replaces the standards previously issued as follows.
--- GB 3235-1982, GB/T 3235-1999.
Basic fan type, size parameters
And performance curve
1 Scope
This standard specifies the basic type, size parameters and characteristics of fan.
This standard applies to industrial, except jet fan, cross flow fan or similar purposes and household equipment used in centrifugal fan
And axial fans.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research

3 basic types
3.1 fan airflow direction according to the motion classification can be divided into centrifugal and axial fan, see definition in JB/T 2977.
3.2 Fan pressing force can be classified into low, medium, high pressure fan, see definition GB/T 19075.
3.3 Fan can be divided according to the direction of rotation clockwise and counter-clockwise rotation, see definition in JB/T 2977.
3.4 Press fan lubrication can be divided into grease and oil lubrication.
3.5 Fan bearing type can be divided according to Rolling and plain bearings.
3.6 Press fan support can be divided into cantilevered and double support type, see definition in JB/T 2977.
3.7 centrifugal fan by way of the intake points for single suction and double suction, see definition in JB/T 2977. Single or double suction fan suction points
Is not brought into the gas tank (axial intake Figure 4) and into the gas tank (radial intake Figure 5).
3.8 Axial Fan Press series can be divided into single-stage and multi-stage axial fan axial fans.
3.9 If the axial fan blade adjustment, can be divided into stationary blade rotor blades adjustment and regulation. See definition in JB/T 2977.
3.10 Fan Drive type can be divided into direct-coupled motor, pulleys, couplings and other types.
Symbol and Structure 3.10.1 centrifugal fan various types of transmission described in Table 1 and Figure 1.
