优选前情况:抛砂机的抛头上仅装有一只叶片,通过传动装置作旋转运动,靠该叶片进行抛砂。抛头安装后虽经静平衡校正,但在有工作负荷情况下,由于动平衡问题以及负荷(砂重)等因素的影响,使抛头失去原来的平衡状态,带来很大振动,经研究分析,认为可以通过调整抛砂叶片重量的方法来达到工作平衡,原来叶片重量为3.4斤,以此为起点对叶片重量进行优选。 Preferred Pre-condition: The throwing head of the sand throwing machine is equipped with only one vane for rotational movement by means of the transmission, and the sand is thrown by the vane. Despite the static balance after the first installation after the correction, but in the case of work load, due to balance issues and load (sand weight) and other factors, the loss of the original balance of the thrown head, bring great vibration, after research Analysis, that can adjust the weight of the method of throwing sand to achieve work balance, the original blade weight of 3.4 pounds, as a starting point for the preferred blade weight.
