在
濟南廚房排煙工程應用的全過程中，維護非常重要，可以降低常見故障的概率。下面就為大家介紹一下廚房排煙工程的傳動鏈和動滑輪的保養。
In the whole process of the application of Jinan kitchen smoke exhaust project, maintenance is very important, which can reduce the probability of common failures. Now let's introduce the maintenance of the transmission chain and movable pulley of the kitchen smoke exhaust project.
廚房油煙過濾器和排油煙機械的風阻會增加，所以一般水平間距應為15厘米，傾斜度應在2%以上，水平端裝有活接頭，便于物品的分揀在管線中。如果廚房油煙過濾器是新建的，應盡量放在排煙離心風機前面，這樣可以增加排油煙管和離心葉輪的油煙附著力，維護保養可以延長循環時間管道疏通和離心風機。與排風罩相連的立管上應設置排風量保持閥。
The wind resistance of kitchen oil smoke filter and oil smoke exhaust machinery will increase, so the general horizontal spacing should be 15 cm, the inclination should be more than 2%, and the horizontal end is equipped with a flexible joint to facilitate the sorting of items in the pipeline. If the kitchen lampblack filter is newly built, it should be placed in front of the smoke exhaust centrifugal fan as far as possible, so as to increase the lampblack adhesion between the lampblack exhaust pipe and the centrifugal impeller, and the maintenance can extend the cycle time, pipe dredging and centrifugal fan. The riser connected with the exhaust hood shall be provided with an exhaust volume holding valve.
傳動鏈和動帶輪維修時，鏈片不得有裂紋和變形，需要轉動靈活。每20段拉伸不超過標準值（8毫米）。傳動鏈銷的磨損不應超過原直徑的5%，不應有嚴重的彎曲、疲勞裂紋和腐蝕。如果超過允許條件，則應更換。如果動帶輪表面磨損不均勻，兩個動帶輪直徑差超過0.2mm，動帶輪表面就會出現臺階或痕跡，危及傳動鏈的正常運轉。應該更換。
When the transmission chain and movable pulley are repaired, the chain piece shall not have cracks and deformation, and it needs to rotate flexibly. The tension of every 20 segments shall not exceed the standard value (8 mm). The wear of the drive chain pin should not exceed 5% of the original diameter, and there should be no serious bending, fatigue cracks and corrosion. If the allowable conditions are exceeded, it should be replaced. If the wear on the surface of the movable pulley is uneven, and the diameter difference between the two movable pulleys exceeds 0.2mm, steps or traces will appear on the surface of the movable pulley, endangering the normal operation of the transmission chain. It should be replaced.
檢修主、側輥時，檢查主、側輥磨損痕跡是否均勻。磨損程度沿直徑方向，主輥1.0mm，側輥0.5mm。否則，應更換。維護內外門架時，內外門架應垂直，全長不平行度不超過1mm，應用度為3mm。否則，它應該被恢復。使用磁力檢查和敲擊檢查是否有裂縫。如果是這樣，它應該恢復。
When overhauling the main and side rollers, check whether the wear marks of the main and side rollers are uniform. The wear degree is along the diameter direction. The main roll is 1.0mm and the side roll is 0.5mm. Otherwise, replace it. When maintaining the inner and outer door frames, the inner and outer door frames should be vertical, with the overall non parallelism of no more than 1mm and the application degree of 3mm. Otherwise, it should be restored. Use magnetic inspection and knocking to check for cracks. If so, it should be restored.
檢查變形或變形。當內彎曲變形全長超過1.5mm，總橫向寬度差超過1.5mm，內門架現澆板彎曲變形超過2.0mm時，應予以修正。當整體變形嚴重，滑軌內部規格超過磨損程度時，應損壞。當內外門架的內外滑軌側面磨損，臺階達到2mm時，應更換或翻新滑軌。
Check for deformation or deformation. When the total length of the internal bending deformation exceeds 1.5mm, the total transverse width difference exceeds 1.5mm, and the bending deformation of the cast-in-place slab of the internal portal frame exceeds 2.0mm, it should be corrected. When the overall deformation is serious and the internal specification of the slide rail exceeds the wear degree, it should be damaged. When the sides of the inner and outer sliding rails of the inner and outer door frames are worn and the steps reach 2mm, the sliding rails should be replaced or renovated.
The above is about the maintenance of the drive chain and movable pulley of the kitchen smoke exhaust project. If you have a demand for the kitchen smoke exhaust project or equipment, please follow our website http://www.pvcbox.cn Check the relevant information!
