We provide the following services related to on-site monitoring and vibration control:⏹ Ground Vibration and Airblast ⏹ Acceleration⏹ Regression AnalysisThe pre-blast or pre-construction conditionsurvey is invaluable as a public relation tool and as protection against false claims of vibration damage. Our professionals document pre-construction conditions of adjacent structures with written notes, photographic and videotaped recordings, measurements, and sketches. Schnabel can also provide damage claiminvestigations to delineate the nature of alleged damage. These services are complete with the analysis of available vibration data andcorrelating the data with current vibration criteria.Schnabel offers rentals and service ofseismographs and other equipment including:⏹ Instantel Blastmate III ® andMiniMate ® Seismographs ⏹ Remote Station Installation ⏹ Software updatesOther vibration services offered by Schnabel include monitoring of:⏹ Construction Activities⏹ Demolition of Bridges and Buildings ⏹ Machinery⏹ Traffic-generated Vibration StudiesVibrations caused by various construction and excavation activities are a common occurrence in today's environment.

浅谈寿力螺杆空压机的高排气温度故障的处理高排气温度是螺杆空压机最常见的故障，其危害也较大。

设备长期在高排气温度状况下运行，主要有以下危害:(1)、排气温度越高，压缩机为考虑膨胀而留的间隙越大，压缩机的效率降低，导致电能依旧消耗，产气量下降;(2)、降低油的使用寿命;(3)、高排气温度会导致更多的润滑油处于气相，增and performance test copies of the record.

实验采用 压电陶瓷作为扰动源，通过数字相干解调方法进行了相位解调。

实验结果表明，相位模糊同时存在于 每条相位解调曲线上和曲线之间，因此需要进行两次相位解卷绕消除相位模糊现象；同时，对实验中产 生的相位错乱进行了分析，指出相位解卷绕阈值和扰动位置相位的剧烈变化导致了扰动位置相位解卷 绕结果不准确，提出了采用相位差变化峰之后的临近位置处的相位变化来还原扰动。

实验表明，这种 方法能够正确还原扰动信号，能够对10 Hz〜1.5 k H z范围内的扰动信号进行准确解调，可同时响应并解 调光纤沿线多点扰动，且相位变化幅值与扰动强度具有良好的线性关系。
