背景资料:

某安装公司总包氮氢压缩分厂全部机电安装工程,其中氮氢压缩机为多段活塞式,工作压力32MPa。电机与压缩机本体分两件进场,现场用齿式联轴器连接。压缩机系统的管道随机组订货,现场组装试验。开工前,安装公司决定压缩机系统的机械设备、电气自动化、管道等主体工程由本单位自行安装,防腐保温及其他非主体工程分包给具有相应资质的分包单位承担,安装公司对分包工程从技术、质量、安全、进度、工程款支付等进行施工全过程管理。

施工前,施工方案编制人员向施工作业人员作了分项,专项工程的施工方案交底,由于交底内容全面,重点突出,可操作性强,故施工中效果明显,工程进展顺利。

试运行阶段,一台压缩机振动较大,经复查土建无施工质量问题,基础无下沉;设备制造质量全部合格;复查安装记录;垫铁设置合理且按规定定位焊接,一、二次灌浆均符合质量要求,测量仪器精度合格,各环境因素对安装无影响,建设单位要求安装公司进一步认真复查并处理。

根据背景资料分析可能引起压缩机振动大的原因,应由哪个单位承担责任?
