柴油發(fā)電機風扇皮帶的松緊度調整方法是:在皮帶中部用30-50牛頓的力按下或拉起、皮帶與原來位置相差15-20毫米，皮帶的松緊度視為正常, 否則應進行調整。其方法按不同構造分為三種：一是設有張緊輪結構的。可松開固定螺母, 擰轉調節(jié)螺釘, 上下移動張緊輪, 達到所雷要的松緊度；二是風扇和發(fā)電機共用一根皮帶驅動的, 可移動發(fā)電機支架, 改變其皮帶輪位置,達到所需要的松緊度；三是皮帶輪由兩半組成的, 先松開固定螺栓, 然后旋轉可調的半邊皮帶輪, 以此改變所合成的皮帶輪糟寬,從而升降三角皮帶, 達到所需要的松緊度。如皮帶嚴重磨損或折斷, 應及時更換。有的柴油機風扇皮帶是兩根, 同時更換, 以免其松緊不一, 用力不均, 引起故障。
The adjustment method of the tightness of the fan belt of the diesel generator is: press or pull the belt with 30-50 N force in the middle of the belt, and the belt is 15-20 mm away from the original position. The tightness of the belt is considered normal, otherwise it should be adjusted. The method can be divided into three types according to different structures: one is equipped with a tensioning wheel structure. Loosen the fixing nut, turn the adjusting screw, and move the tensioning wheel up and down to achieve the required tightness; The second is that the fan and the generator share a belt drive, and the generator bracket can be moved to change the position of its belt pulley to achieve the required tightness; Third, the belt pulley is composed of two halves. First loosen the fixing bolts, and then rotate the adjustable half of the belt pulley to change the width of the resultant belt pulley, so as to lift the V-belt to achieve the required tightness. If the belt is seriously worn or broken, it should be replaced in time. Some diesel engine fan belts are two, and they should be replaced at the same time to avoid failure caused by uneven tightness and force.
風扇皮帶保持正常的緊度, 以保證冷卻來統(tǒng)正常工作。如果皮帶過松, 容易打滑, 使風扇和水泵轉速降低, 引起風扇鼓風童不足, 水泵泵水能力降低, 導致散熱不良、機溫過高。生產實踐中常發(fā)生水箱高溫不下的情況, 停車檢查, 調整皮帶緊度, 機溫過高的現(xiàn)象即刻消除。但如果皮帶過緊也會使軸和軸承磨損加劇。同時, 三角皮帶兩邊抖面與皮帶輪糟過分摩擦, 易于損壞皮帶、消耗功率。因此, 在柴油機使用過程中, 應及時檢查風扇皮帶的松緊程度。以便保證三角皮帶正常工作, 改善柴油機的整機性能。
The fan belt shall be kept in normal tightness to ensure the normal operation of the cooling system. If the belt is too loose, it is easy to slip, reducing the speed of the fan and water pump, causing insufficient fan blower, reducing the water pump capacity, resulting in poor heat dissipation and high machine temperature. In production practice, the high temperature of the water tank often occurs. Stop the machine for inspection, adjust the belt tightness, and immediately eliminate the phenomenon of excessive machine temperature. However, if the belt is too tight, the wear of shaft and bearing will be aggravated. At the same time, the buffeting surfaces on both sides of the V-belt rub excessively with the pulley groove, which is easy to damage the belt and consume power. Therefore, check the tightness of the fan belt in time during the use of the diesel engine. In order to ensure the normal operation of V-belt and improve the overall performance of diesel engine.
