前彎風向標持續離心風機（jī）正常運轉運行速度比較而言較低，一般情況下可用於暴風（fēng）量、低靜壓（yā）的工況。原型的客流量適用範圍為30%-80% WOCMS(全（quán）進行自如客流量),萬丈的（de）靜壓工（gōng）作效率為60%-68%，一（yī）般情況（kuàng）下出現於靜壓（yā）更加最大值的稍右邊。權力雙曲線具（jù）備增添的進行（háng）目標，是“易滿載型”風機。前彎風向標持續離心風機的長處是物價低、革命低，可錄取較細的軸和較小的滾珠（zhū）軸承，且具備較寬的（de）進行操作適用範圍。毛病是使用性能雙曲線幾何形狀或許與管（guǎn）網障礙物雙曲線平行線，且係（xì）統靜壓進一步減少或許（xǔ）進行引（yǐn）起（qǐ）發電機滿載。除此之外，風向標整體結構極限抗（kàng）拉強度較低，無法正常運轉於較高的革命。
The centrifugal fan with forward curved blades operates at a relatively low speed and is usually suitable for high air volume and low static pressure. Typical flow range is 30% - 80% WOCMS (full open flow). The highest hydrostatic efficiency is 60% - 68%, which usually occurs on the slightly right side of the maximum hydrostatic pressure. The power curve has a tendency to increase, and it is an "easy overload" fan. The advantages of forward-bending blade centrifugal fan are low cost, low rotating speed, the choice of finer shaft and smaller bearings, and a wide operating range. The disadvantage is that the shape of the performance curve may be parallel to the resistance curve of the pipeline network, and the reduction of the static pressure of the system may lead to overload of the motor. In addition, the blade structure strength is low and can not run at a higher speed. 1、需（xū）要構件彼此之間進行矛盾
1. Conflict between falling parts
滾珠軸（zhóu）承（chéng）間和齒麵間彼此之間做著相互活動，進行幫子表積極參與進行滑溜油的實際作用，就是說將進行矛（máo）盾麵（miàn）離隔，來需要構（gòu）件彼此之間的進行矛盾（dùn）力，發展機械裝備的實際成（chéng）效。
Between bearings and tooth surfaces, there is mutual movement, which participates in the role of lubricating oil on the surface, that is, separating the contact surface to reduce the resistance between components and advance the effectiveness of mechanical equipment.
2、進（jìn）一（yī）步降低破壞
2. Reduce wear and tear
在滾珠軸（zhóu）承或齒麵間的進行滑溜油能需要進行矛盾載重，接下來進一步降低設（shè）備的破壞。
Lubricating oil between bearings or tooth surfaces can reduce the resistance load, and then reduce the wear of equipment.
3、比賽
3, cooling
因為軸流風機的實際作用，設備正處在長時段的工作，表麵熱度必然高熱，加入進行滑溜油就是說能需要設備的進行矛盾進行狂熱。
Because of the role of the axial flow fan, the equipment is in a long period of operation, the external temperature is bound to be high heat, adding lubricant is able to reduce the device's anti-trigger heat.
4、冬防
4, anticorrosion
正處在（zài）戶外，長時段會進行引起設備的表麵發生剝蝕，加入進行滑溜油可以隔離大氣、破壞固體等要樣兒。
Being outdoors for a long time will lead to rust on the surface of the equipment. Adding lubricating oil can isolate air and corrosive gas.
