離心風機定義、組成結構及修理與保養方法解讀

一、離心風機定義：
離心風機是一種用於緊縮和運送氣體的機械，從能量觀念來看，它是把原動機的機械能量轉變為氣體能量的一種機械。
二、離心風機的組成及結構
1.離心風機的組成:
離心風機選用單吸入D型傳動結構，由聯軸器將離心風機和電機聯接起來。離心風機本體首要由機殼、進風口、轉子組（葉輪及主軸）、軸承箱、聯軸器等部分組成。(F型傳動它是雙支撐兩個軸承箱,單吸的有一個進風室,雙吸的有兩個進風室。C、B型傳動的有主動輪和被動輪)。機組除離心風機本體外，依據用戶需求，還可裝備各種外配套，常見的有：電機、調理門、全體支架、電動執行器、消聲器等。
2.離心風機的結構簡介:
2.1離心風機可制成順轉或反轉兩種型式：從電機一端正視，如葉輪按順時針方向旋轉稱順旋離心風機，以“順”表明；按逆時針方向旋轉稱逆離心風機，以“逆”表明。離心風機的出口方位以機殼的出口視點表明：“順”、“逆”均可制成0°、45°、90°、135°、180°、225°共六種視點。也可按用戶的要求制成其他的特別視點。
依據詳細的狀況，軸承箱有以下兩種：（1）水冷卻軸承箱（2）油冷卻軸承箱
First, the definition of centrifugal fan:
A centrifugal fan is a machine for tightening and transporting gas. From the point of view o彩色沥清地坪f energy, it is a kind of mechanical energy that transforms the mechanical energy of the original motive into the gas energy.
Two. The composition and structure of centrifugal fan
1. the composition of the centrifugal fan:
The centrifugal fan adopts the single suction D type transmission structure, and the centrifugal fan and the motor are connected by a coupling. The centrifugal fan body is mainly composed of the shell, inlet, rotor group (impeller and spindle), bearing box, coupling and so on. (F type transmission, it is double support two bearing box, single suction has an air inlet room, double suction two air intake room. The C, B type drive has the active wheel and the passive wheel. In addition to the centrifugal fan, the unit can also be equipped with all kinds of external accessories according to the needs of the user, such as motor, conditioning door, all support, electric actuator, muffler and so on.
2. introduction of the structure of centrifugal fan:2.1 centrifugal fan can be made into two types of rotating or reversing: from one side of the motor, if the impeller is rotating clockwise in the direction of clockwise, it is called CIS centrifugal fan, and the reverse centrifugal fan is rotated in the direction of counterclockwise, and it is "inverse". The exit orientation of the centrifugal fan shows that the "Shun" and "reverse" can be made into six viewpoints of 0, 45, 90, 135, 180 and 225 degrees. Other special viewpoints can also be made according to the requirements of users.
According to the detailed situation, the bearing box has two kinds: (1) water cooling bearing box (2) oil cooling bearing box.
三.離心風機的修理與保養
正確的保護、保養，是離心風機安全可靠作業，進步離心風機運用壽命的重要確保。因而，在運用離心風機時，有必要引起充沛的註重。
3.1.葉輪的修理、保養在葉輪作業初期及一切定時查看的時分，隻需一有機會，都有必要查看葉輪是否呈現裂紋、磨損、積塵等缺點。隻需有可能，都有必要使葉輪保持清潔狀況，並定時用鋼絲刷刷去上面的積塵和銹皮等，由於跟著作業時刻的加長，這些塵埃由於不可能均勻地附著在葉輪上，而形成葉輪平衡破壞，以致引起轉子振蕩。葉輪隻需進行瞭修理，就需求對其再作動平衡。如有條件，能夠運用便攜試動平衡儀在現場進行平衡。在作動平衡之前，有必要查看一切緊定螺栓是否上緊。由於葉輪現已在不平衡狀況下作業瞭一段時刻，這些螺栓可能現已松動。
3.2.機殼與進氣室的修理保養除定時查看機殼與進氣室內部是否有嚴重的磨損，鏟除嚴重的粉塵堆積之外，這些部位可不進行其他特別的修理。定時查看一切的緊固螺栓是否緊固，對有壓緊螺栓部的離心風機，將底腳上的蝶形繃簧壓緊到圖紙所規則的裝置高度。說
3.3.軸承部的修理保養常常查看軸承潤滑油供油狀況，如果箱體呈現漏油，能夠把端蓋的螺栓擰緊一點，這樣還不可的話，可能隻好換用新的密封填料瞭。
3.4.其他各配套設備的修理保養各配套設備包括電機、電動執行器、儀器、儀表等的修理保養詳見各自的運用說明書。這些運用說書都由各配套制作廠傢供給，本制作廠將這些說明書隨機裝箱供給給用戶。
3.5.離心風機停止運用時的修理保養離心風機停止運用時，當环境溫度低於5℃時，應將設備及管路的餘水放掉，以防止凍壞設備及管路。
3.6.離心風機長期泊車寄存不用時的保養作業（1）將軸承及其它首要的零部件的外表塗上防銹油避免銹蝕。（2）離心風機轉子每隔半月左右，應人工手動搬動轉子旋轉半圈（既180°），搬動前應在軸端作好符號，使本來最上方的點，搬動轉子後位於最下方。

Three. Repair and maintenance of centrifugal fan
Proper protection and maintenance is an important guarantee for the safe and reliable operation of centrifugal fans and improving the service life of centrifugal fans. Therefore, in the use of centrifugal fans, it is necessary to cause enough attention.
3.1. impeller repair, maintenance in the initial stage of the impeller operation and all time to view the time, only a chance, it is necessary to see whether the impeller presents cracks, wear, dust and other shortcomings. Only possible, it is necessary to keep the impeller clean, and regularly use steel wire brush to the dust and rust and so on, because of the lengthening of the operation time, these dust can not be evenly attached to the impeller, and formed the impeller balance damage, causing the transfer of Zi Zhendang. The impeller only needs to be repaired, so it needs dynamic balancing. If conditions permit, we can use portable test balance to balance at the scene. Before moving balance, it is necessary to see if all the tightening bolts are tightened. Because the impeller has been working under unbalanced conditions for some time, these bolts may be loose.
The repair and maintenance of the 3.2. casing a印花地坪nd the intake chamber can be used to check whether there is serious wear in the interior of the casing and the intake chamber, and in addition to the accumulation of serious dust accumulation, these parts can not be repaired in particular. Check the fastening bolts of all the fasteners regularly, and press the butterfly spring on the bottom to the height of the set of the drawing. say
The repair and maintenance of the 3.3. bearing section often looks at the oil supply condition of the bearing lubricating oil. If the tank is leaking, the bolt can be tightened up a little. If it is not possible, it may have to be replaced with a new sealing packing.
The repair and maintenance of other supporting equipment of 3.4., including motor, electric actuator, instrument, instrument, etc., are detailed in the respective application instructions. These application storytelling are supplied by all the supporting manufacturers. The production plants are randomly supplied to these users.
When the centrifugal fan is stopped to use when the 3.5. centrifugal fan is stopped, when the ambient temperature is below 5 C, the residual water of the equipment and pipeline should be released to prevent the freezing equipment and pipeline.
3.6. centrifugal fan for long term parking service maintenance when not in use (1) put the rust bearing oil on the surface of bearings and other principal components to avoid rust. (2) every half of the rotor of the centrifugal fan should be manually moved with a rotating half circle (180 degrees) manually, and a symbol should be made at the end of the rotor before moving, so that the original point is located at the bottom of the rotor.
Note: the type of bearing of the centrifugal fan is detailed in the general drawing.
