首先得明白冰箱噪音是哪里产生的.通常有如下几个原因:
1.压缩机噪音.普通国产档次不高的压缩机会有一定噪音.正常情况下不影响使用.尚不至于影响休息.如果有不规律的噪音.或者声音过大.可以考虑更换压缩机.启动和关闭时候的咔哒声是自动开关的继电器动作.是正常的.
2.冰箱几个支撑脚直接与硬地面如瓷砖接触.会将振动放大.产生噪音.可以在支撑脚下放置一块硬橡胶.比如旧布鞋底之类.或者找修自行车的.修鞋的要一块剪成小块垫上.不能太厚.不要超过5毫米厚.
3. 由于搬动冰箱最常引起的噪音增大就是背后的散热管.散热管被挤压变型后很容易增大振动.产生噪音.冰箱刚启动时候用手摸一下后便散热管.哪里振动厉害哪里就是噪声源.注意可别开半天再摸啊.很烫的.用电工胶布将振动的散热管和稳定的散热管固定在一起.每个一段固定一下.一般固定两三个地方就可以大大降低噪音.
普通冰箱只要制冷.噪音大小基本不影响使用寿命.只是影响人心理.新买冰箱除非是海尔那样的超静音.其他品牌几乎都会让人短时间不习惯.过段时间就习惯了.注意不到冰箱噪音了.制冷正常就不应该总修.越修噪音越大.
下面还有几种可能:
如果声音是下面发出的:可能是压缩机下面的避振脚老化造成的(更换避振脚),另一种可能是压缩机处的管路相造成的(修正管路正常到位就可),最后一种可能就是压缩机自身运转机械声过响(检修方法就是只能更换同型号压缩机了)
如果声音是上面发出来的(哮叫声):有两种可能.一是.在冰箱制冷状况正常的情况下.冷冻室内的风扇电机老化所至.更换此罩极式电机就可
二是.冰箱的制冷状况不佳的情况下.可能是自动化霜系统故障(不化霜的故障).造成风扇电机的叶片碰到霜发出的声音.解决办法更换自动化霜系统所坏的零部件使冰箱正常运转就可.
还有的就是最好请该品牌的售后服务部门上门检修
解决办法:
背面与墙面成一定的倾角
使冰箱的背面与墙面成一定的倾角.背面与墙面成l-3度倾角以后.冰箱的一侧开口大.一侧开口小.呈现喇叭状.大的一侧放出的噪音多.应面对物体,小的一侧噪音出来少.应面对人的活动区.
管路与箱体加固牢靠要检查调整外管路与箱体之间连接加固部分是否松动.从而避免压缩机工作时产生共振.所以.外管路一定要固定好.螺栓要加弹簧垫圈.以防松动.
压缩机底座要上牢固
如果用手紧按压缩机后.噪声明显减低.将手抬起噪声又增大.一般是压缩机底座固定减振胶垫受力不均或螺栓松动.压缩机底板不牢固造成.应调整.拧紧连接部分螺栓和更换失去弹力的垫圈.
用橡皮块抑制管子振动电冰箱在使用过程中如噪声较大.可取废自行车外胎.剪成直径为30毫米的圆形状.中间剪出直径5毫米左右的圆孔.再从外边到中心剪一下.以便把橡皮贴到管子上.等电冰箱压缩机运转时.用手摸管子.凡有抖动感觉的管子.都可套上几个这种橡皮块.一台冰箱需套10-20个.噪声马上会降下来.
这是因为橡皮块抑制了管子振动所产生的[共鸣".
适当垫高冰箱的四个角
将冰箱垫高3-6厘米并调整四角平衡.使箱体底部空气对流空间增大.这样.压缩机噪音和下部其他噪音从箱体底部出来.减少了从冰箱两侧及上部出来的噪音
