正常来说塑料挤出机的试车噪音不超过85db(A),这个噪音标准是挤出机制造质量中的一个主要指标,它是挤出机组零件的制造质量和装配精度的综合反映。当这个噪音值过高时,第 步要检查各紧面螺母是否松动,皮带轮的安全罩是否刮安全罩等处。这些地方容易在搬运运输中发生问题,不属于挤出机设备的质量问题,如果这些问题解决了,噪音值还较高,就要从下面几个部位查找。
一、螺杆在机筒中转动与摩擦声音的产生原因1、螺杆与机筒装配同心度误差大。
2、机筒端面与机座连接法兰的端面与机筒中心线的垂直度误差较大。
3、螺杆弯曲变形,轴心线的直线度超差较大。
4、挤出机的螺杆与其支撑传动轴的装配间隙过大,转动时不同心度误差较大。4、
二、塑料挤出机的电机转动声音较大的原因
1、转子轴承的较大低。
2、转子轴的轴心线的直线度误差较大。
三、塑料挤出机皮带传动产生较大噪音的原因,
1、皮带轮内孔与传动轴的装配间隙较大
2、皮带轮的制造精度低,端面和外圆的跳动较大。
3、两传动皮带轮的安装位置,端面不在一个平面上,误差较大。
四、齿轮传动噪音较大的产生原因
1、齿轮制造精度不高,齿轮齿矩误差大,
2、齿轮的传动轴中心线误差值较大。中心距较小时,产生齿轮传动齿合干涉噪音。
3、轴的支撑滚动轴承精度低,
4、两传动轴中心线的平行度超差,使齿轮不能正确齿合传动。
