用途及结构
G、Y4—73№20 F～31．5 F 是与 10 万。20 万千瓦火力发电机组配套的鼓引风机。 它是在 G、Y4—73Nn20 D～29．5 D 的基础上，根据 20 多年的生产和使用中存在的问题重新设 m 竹 新型产品。与原系列风机相比作了如下重大改进： 1．将原风机悬臂支承(D 式)传动方式改为中间支承(F 式)的传动方式，提高了风机运行的稳定性，其对 于引风机来说，由于叶轮磨损和积灰以后影响转子的平衡，容易引起风机振动，这一改进尤为重要。 2．通过模型(叶轮外径 D=1000 咖)试验，增加了适应于该型风机的进气室，改原进风口的形状为偏心 进风口。过去风机生产厂不制造附带进气室，而各电厂自行配置的气室多不能适应该风机的工作，容易引 起进气涡流，使风机的机壳、进气室以及风道产生剧烈振动，风机工况严重恶化，风量、压力、功率大幅 度波动，使设备不能正常运行，使用该系列新型风机，可使这一问题得以圆满解决。 3．在进气室的进口处装有翼形叶片调节门，用以调节风机的特性，提高风机的调节效率，调节叶片的 支撑处装有滚动轴承，转动灵活，使用可靠。 4．由于大部分送风机使用环境温度较高，轴承容易发热，因而新系列风机的轴承箱也和引风机一样采 用水冷式。 5．新风机轴承箱改进了油封设计，并增加了放气塞，解决了漏油问题。 6．由于滚动轴承标准的改变，新风机调整了轴承型号，同时由于传动方式的改变、轴的受力情况更为 合理，因而轴承在使用中出现的问题大为减少。 7．新风机的设计增强了机壳和进气室的刚性，在机壳和进气室的外部焊有适当高度的井字格筋板，内 部焊有空心管支撑，因而消除了由于机壳的刚性不足而产生的振动。 8．考虑到引风机叶轮的尘粒磨损问题，增大了翼形叶片头部的实心部分，并在叶片靠后盘处增加了防 磨板，同时在易磨损处用耐磨损焊条堆焊耐磨层，硬度可达 HRC48 以上，延长了叶轮的使用寿命，满足了 电厂使用和维修的要求。 9．按实际情况，新风机设计成进口 135。和出口 45。的型式，这样在不动风机主体和进出风口管道的 情况下，即可方便地拆除、进气室、进风口上的一部分，从而风机的转子可从上部垂直吊出。 10．扩大设计生产了№31．5F 鼓、引风机。 Y4—2×73№28．5F 锅炉离心引风机适用于火力发电厂中 30 万千瓦发电机组蒸汽锅炉引风系统，亦可 作为温度不超过 200℃气体排送。如用户选用此型风机时，所需性能为更适应于锅炉的配套需要，我厂可按 用户要求做相应的“点菜”设计。 Y4—2×73№28．5F 锅炉离心引风机采用双侧进气、双支撑结构，整个风机由转子组、机壳、进风口、 进气箱、调节门、传动组、滑动轴承、盘车装置及强制润滑系统等组成。叶轮叶片采取了耐磨措施，配套 双速电机及传动组，不但解决了气流转弯的稳定性，也提高了风机的调节效率。转子组经过动静平衡校正， 配制了强制供油润滑系统，因而风机能够长期稳定运行。

Twin City AXICO ANTI-STALL可调旋翼风机系列产品说明书
CATALOG AX351 | JUL Y 2001WWW.TCF.COMTwin City FanAXICO ANTI-STALL ®CONTROLLABLE PITCH-IN-MOTION ANDADJUSTABLE PITCH-AT-REST VANEAXIAL FANS FPAC | FPMC | FPDATwin City Catalog AX3512AXICO ANTI-STALL ® is the only controllable pitch vaneaxial fan designed to totally eliminate stall, sys-tem surging and increased noise levels often expe-rienced by ordinary controllable pitch vaneaxial fans under unstable conditions.Normal axial fans can be forced to perform within unstable working ranges when operating conditions are unfavorable. This can happen when the fan sys-tem is subjected to sudden or unexpected variations in pressure which can be caused by:• dampers that close suddenly or fail to open • hypersensitive automation control systems • improper parallel fan starting sequences• incorrect or optimistic pressure drop calculations • clogged filters, etc.When a fan operates in an unstable range the blades are submitted to sharp variations in pressure which will ultimately result in blade fatigue and even-tual fan failure.AXICO ANTI-STALL ® provides a patented solution to solve the problems associated with fan stall in a simple, ingenious method, without the addition of any moving parts or expensive electronic controls. The secret lies in the small bypass vanes that are inte-grated into the chamber placed around the periphery of the fan impeller. The bypass vanes “catch” tur-bulent airflows produced at the tips of the blades, which normally cause stalling, and restore them to stability in the proper flow direction.AXICO ANTI-STALL ® has no stall area and no stall limit. While this means that the AXICO ANTI-STALL ® can be selected directly at any point on the perfor-mance curves in this bulletin without consideration of any safety range against the possibility of stall, we strongly recommend selections be made toward the central part of the fan curve at the point of highest possible efficiency.Anti-stall ring with bypassvanesNEMA designed foot-mounted motor com-pletely exposed for ease of service andaccessibility.Motor supported onstructural baseupstream of propeller.Inlet bell designed exclusively for free inlet applications such as custom air handlers (duct configurations also available.)Vane section provided with removable access panel to provide unimpeded access to fan impeller and blade actuator mechanism.Fan supported from awelded steel channel base (minimum 5" channel).Note: Standard inlet guards have been removed for clarity.Capabilities:• Impeller diameters from 311∕2" to 783∕4"• Capacities of 2,000 to 200,000 CFM • Static pressures to 10" w.g.AXICO ANTI-STALL ®Twin City Catalog AX3513FPACVariable air volume fan impeller is equipped with an internal pneumatic diaphragm and external Honeywell industrial-grade pilot positioner assembly to simulta-neously vary the pitch angle of all blades identically while the fan impeller is rotating at motor speed. An 80 to 100 psi pneumatic supply air line is required for pitch actuation of this fan. These fans typically operate in a direct-acting mode in conjunction with the building automation temperature control system. The standard pneumatic pilot positioner receives a 3 to 15 psi control signal from the building automation system to modulate the fan blades. An optional elec-tro-pneumatic positioner is available that will modulate blade pitch after receipt of an externally generated 4-20mA electronic control signal.FPMCVariable air volume fan impeller is equipped with a mechanical linkage system that will simultaneously actuate the pitch angle of all blades via one of three basic options:1. A manual lever arm with locking quadrant mounted external to the fan housing.2. A right-angle gear box with manual handwheel mounted external to the fan housing3. A lever arm with electric motor actuator mounted external to the fan housing and capable of auto-matic remote pitch actuation responding to either a 4-20mA or a 135 ohm electronic control signal received from the building-automated temperature control system.FPDAConstant air volume fan impeller is equipped with mechanically-fixed, individually manually-adjustable blades that may only be re-pitched when the fan is stopped. This fan may be operated with a variable frequency drive unit to vary the rotational speed of the impeller and thereby vary the air volume pro-duced while maintaining the ANTI-STALL ® character-istics of the unit.The AXICO ANTI-STALL ® fan can easily be controlled to deliver the required flow or pressure in most situations by properly sizing the fan and then adjusting the blade angle of attack while fan is energized. Blade pitch control can be accomplished in the following ways.Pneumatic Controllable PitchElectric Controllable PitchManual Adjustable PitchVAV Control Flexibility4View of AXICO ANTI-STALL®fan from discharge.Honeywell industrial-gauge pilot positioner withclosed-loop feedback cable is shown standardlymounted on top of straightening vane section.

Draw a line from the appropriate CFM on vertical axis marched CFM (A) to the appropriate RPM on vertical axis marked RPM (C). The point at which this line intersects the vertical axis marked FAN SIZE (B) indicates the most appropriate fan size given that RPM and CFM. As an example, a line drawn between 60,000 CFM and 1800 RPM intersects the fan size line almost precisely in the middle of the area noted as 112. Based upon this, it is probable that a size 112 fan is the best selection. The same line intersects the fan size line at the border between size 125 and size 100. This indicates that a 125 is probably over-sized and a 100 is probably undersized. There may be circumstances where these selections should be investigated. If that is the case, you should consult your local sales representative.Step 2. Having now selected the fan, one must now select the hub and blade combination which is appro-priate. Draw a line from the vertical axis RPM (C) to the vertical axis marked TP/SP (E). In the example shown we have a given value of 4.25" of static pres-sure. Be sure that you use the same fan speed in selecting the hub and blade as you have used in selecting the fan. In this case, we draw the line from 1800 RPM to 4.25" static pressure and it intersects the HUB SIZE vertical axis (D) close to the middle of the zone marked 5-8. This would indicate that the probable selection for 60,000 CFM and 4.25" static pressure is 112-5-8. Note that the same line inter-sected the hub size vertical axis almost at the 6-8 junction. This indicates that the pressure is probably low so that utilization of a 6 hub with 8 blades will result in relatively low efficiencies. NOTE: See perfor-mance curve on page 6.Fan Selection ProcessTwin City Catalog AX3515AXICO ANTI-STALL® fans are characterized by completely stable high efficiency operation over an extremely wide operating range. The risk of stall (surging, instability, etc.) encountered in conventional vaneaxial fan designs has been completely eliminated. Fan performance in this publication is presented as Total Pressure versus CFM at standard air density (0.075 lbs/ft3). The maximum blade angles presented in the published performance curves are the maxi-mum angles for which the fan is designed.For controllable pitch in-flight fans in variable volume situations the maximum design load should ideally be selected to the right and slightly above the peak efficiency ring so that normal operation at modulated partial loads will result in operation at areas of high-est efficiency on the fan curve.Fans with manually adjustable pitch blades for appli-cations in either constant volume or variable speed (frequency) systems should ideally be chosen for normal operation within the peak efficiency ring of the fan curve to insure the highest possible energy savings throughout the complete range of operation. The pressure/flow characteristic of the fan is pre-sented as a total pressure rise between the fan inlet and the fan outlet, providing that the fan is connected to ductwork of the same diameter as the fan. The curves are applicable to either a free or a duct connection at the fan inlet and no provision is made for less than ideal fan inlet conditions within the performance curves. The outlet side of the fan is often connected to a conical regain diffuser that is in turn connected to ductwork or a discharge ple-num. Various system requirements and layouts result in numerous combinations of standard or compact fan designs often used in conjunction with a variety of discharge options (ductwork, outlet transitions, C-D diffusers, acoustic diffusers, etc.). The pressure regain and or applicable discharge connection losses for any instance other than that of a fan connected directly to fan diameter discharge ductwork requires the inclusion of these losses in all presentations of Total Pressure.The following explanation of the performance curves, associated fan laws and formulas should be used to determine and analyze various aspects of fan per-formance.SP = Static PressureVP = Velocity PressurePv = Velocity pressure in fan diameter ductPvD = Velocity pressure in diffuser diameter duct DL = Discharge LossTP = Total PressureTE = Total EfficiencybHP = Brake HorsepowerTP = SP + VP + DLCFM x TPbHP =6356 x TEFan chart is valid for a gas density of .075 lb/ft3.L wt: Total sound power level dB(A)P v: Velocity pressure in fan diameter ductP vD: Velocity pressure in diffuser diameter ductTE: Total efficiencyAspects of Fan SelectionTwin City Catalog AX351 6Twin City Catalog AX3517F ___ - __ - ___ - __ - ___ - ____ - ___AXICO ® = PAC = PDAARR. 4 TYPE 22 = HORIZONTAL FLOOR LEG 4 = HORIZONTAL CEILING CLIP 6 = VERTICAL CLIP ARR. 4 TYPE 33 = FLOOR MOUNT FAN SIZE (cm)080, 090, 100, 112, 125 140, 160, 180, 200MOTOR HP MOTOR RPMBLADE COUNT 8 = IF 5 OR 6 HUB 10 = IF 8 HUB HUB SIZE5 = 50.0 cm Dia.6 = 63.0 cm Dia. 8 = 80.0 cm Dia.NOTES:1.
