Air volume range: 15229~81000om3/h

風壓范圍：553~8720Pa

Wind pressure range: 553~8720Pa

驅動方式：直聯(D)

Driving mode: direct connection (D)

型號范圍8#~31.5#

Model range: 8#~31.5#

方向角度：可制成順時針或逆時針。均可制成0°45° 90°135°180°270°六種角度。

Direction and angle: it can be made clockwise or counterclockwise. It can be made into six angles of 0 ° 45 ° 90 ° 135 ° 180 ° 270 °.

整體結構：風機主要由葉輪、機殼、進風口、調節門及傳動部分組成。

Overall structure: the fan is mainly composed of impeller, casing, air inlet, regulating valve and transmission part.

葉輪：由12片后傾機翼斜切的葉片，焊接于錐弧形的前盤與平板形的后盤中間。由于采用了機翼形葉片，保證了風機高效率.低噪聲、高強度。葉輪經靜、共平衡校正，故運轉平穩。同一機號的通、引風機葉輪結構相同。

Impeller: it consists of 12 blades obliquely cut by backward inclined wing, which are welded between the conical arc front disc and the flat plate rear disc. Due to the use of wing blades, the fan has high efficiency, low noise and high strength. The impeller is adjusted by static and common balance, so it runs smoothly. The impellers of ventilation and induced draft fans with the same unit number have the same structure.

機殼：采用優質鋼板焊接而成的蝸形體。單吸入風機的機殼做成三種不同形式。

Casing: volute body welded with high-quality steel plate. The casing of single suction fan is made into three different forms.

進風口：收斂、流線形的進風口制成整體結構，用螺栓固定在風機入口側。

Air inlet: the convergent and streamlined air inlet is made into an integral structure and fixed on the inlet side of the fan with bolts.

用途：適用于火力發電廠中670t/h以下蒸汽鍋爐的通、引風機系統。

Purpose: it is applicable to the ventilation and induced draft fan system of steam boiler below 670t / h in thermal power plant.

適用環境：通風機輸送的介質為空氣，最高溫度不得超過80℃，引風機輸送的介質為煙氣，最高溫度不得超過250℃。在引風機前必須加裝除塵裝置，以盡可能減少進入風機中煙氣的含塵量。根據一般電廠使用情況除塵效率不得低于85%。

Applicable environment: the medium conveyed by the fan is air, and the maximum temperature shall not exceed 80 ℃,the medium conveyed by the induced draft fan is flue gas, and the maximum temperature shall not exceed 250 ℃. A dust removal device must be installed in front of the induced draft fan to reduce the dust content of the flue gas entering the fan as much as possible. According to the use of general power plants, the dust removal efficiency shall not be less than 85%.

※可特殊定做防爆式、防腐式、耐高溫結構。

※ explosion proof, anti-corrosion and high temperature resistant structures can be specially customized.
