  • 工業風扇高強度螺栓安裝技巧

目前市面上的工業風扇電機輸出軸與輪轂的連接分為兩種,一種是高強度的螺栓連接,還有一種是漲緊裝置形成結構性自鎖,即使在輸出軸端螺栓松脫的情況下,仍然可以保證輪轂和輸出軸可靠的緊固在一起。無論是螺栓連接,還是結構性自鎖與螺栓連接,我們可以發現共同點,都會安裝螺栓,所以現在就聊聊高強度螺栓的安全方法。

      高強度螺栓的安裝應在工業風扇結構構件中心位置調整好后進行,其穿入方向以施工方便為準,并力求一致。高強度螺栓連接副件組裝時,螺母帶圓臺面的一側應朝向墊圈有倒角的一側。對于大六角頭高強螺栓連接副件組裝時,螺栓頭下墊圈有倒角的一側應朝向螺栓頭。一個接頭上的高強螺栓,應從螺栓群中部開始安裝,逐個擰緊。初擰、復擰、終擰都應從螺栓群中部向四周擴展逐個擰緊,每擰一遍均應用不同顏色的油漆做上標記,防止漏擰。安裝高強度螺栓時,嚴禁強行穿入(如用錘敲打)。如不能自由穿入時,該孔應用絞刀進行修整,修整后更大直徑應小于1.2倍螺栓直徑。修孔時,為了防止鐵銷落入板疊縫中,應將四周的螺栓全部擰緊,板疊縫緊貼后再進行絞孔。嚴禁用氣割擴孔。安裝高強度螺栓時,構件的摩擦面應保持干臊,不得在雨中作業。高強度螺栓在終擰以后,螺栓絲扣外露應為2至3扣,其中允許有10%的螺栓絲扣外露1扣或4扣。

      當然以后工業風扇結構件螺栓的連接只是做以保護,更多的還是會使用大王通風特有的漲緊裝置形成結構性自鎖,或者隨著技術發展采用更為先進的連接方式,保證工業風扇運行時的安全。

At present, the connection between the output shaft and the wheel hub of Industrial Fan Motors on the market is divided into two types, one is the high-strength bolt connection, and the other is the structural self-locking of the tensioning device, even if the bolt at the output shaft end is loose, the hub and the output shaft can still be securely fastened together. Whether it is bolt connection, or structural self-locking and bolt connection, we can find common ground, will install bolts, so now talk about high-strength bolt safety methods. The installation of high-strength bolts should be carried out after the adjustment of the central position of the structural components of industrial fans. The side of the nut with the round countertop shall be oriented to the chamfered side of the Washer when the high-strength bolt joint fittings are assembled. The chamfered side of the Washer under the bolt head shall be facing the bolt head when assembling the high-strength Bolt Joint. High-strength bolts on one joint shall be installed from the middle of the Bolt Group and tightened one by one. The initial screw, the compound screw, the final screw should be from the middle of the bolt group to expand around one by one screw, each screw a different color of paint should be used to mark, to prevent screw leakage. When installing high-strength bolts, do not force through (E. G. BY HAMMERING) . If the hole can not be penetrated freely, the reamer should be used for trimming. The maximum diameter after trimming should be less than 1.2 times the diameter of the bolt. In order to prevent the Iron Pin from falling into the lamination seam, all the bolts around should be tightened, and the lamination seam should be pressed against the reaming hole. Gas Cutting and reaming is strictly prohibited. When installing high-strength bolts, the friction surface of components should be kept dry and should not be operated in the rain. After final tightening of high-strength Bolts, the bolts should be exposed to 2 to 3 buttons, which allows 10% of the bolts exposed to 1 or 4 buttons. Of course, in the future, the bolt connection of the structural parts of industrial fans will only be used for protection. More and more people will use the special tensioning device of king ventilation to form structural self-locking, or adopt more advanced connecting methods with the development of technology, to ensure the safety of industrial fan operation.
