Hoisting function of seismic support
Importance of seismic support for buildings seismic support can play an excellent role in structural maintenance of buildings.
1、 To be smooth and stable: when the composite seismic support with guaranteed quality stops installation, it is not only necessary to ensure that the support is firmly fixed, but also the position of the support should be calculated accurately. After installation, it is necessary to ensure the flatness, and also close contact with the supporting pipeline, so that it can play an excellent seismic role.
2、 No jamming phenomenon: the combined seismic support has many different categories. Assuming that the required installation of the guiding and sliding seismic support, the installation position should be offset from the center of the maintenance surface to the purpose of the opposite displacement. The sliding surface of the seismic support should be kept clean and flat. During the sliding process of the support, there should be no tilting and jamming phenomenon.
3、 Welding treatment shall be qualified: since there are many components in the combined seismic support and hanger, and the support and hanger need to be welded, qualified welders shall be responsible for welding treatment, and the center of the required welding shall be free from missing welding, lack of welding, welding cracks and other defects. At the same time, When the pipeline is directly welded with the seismic resistance, the pipeline shall not show undercut and burn through.
4、 The temporary support shall not be in dispute with the formal support: when the temporary support is assumed to be selected first during installation, the temporary support and hanger shall not be in dispute with the position of the formal composite seismic support, and obvious signs shall be made to distinguish them. When the installation is completed, the temporary support shall be removed.

The range of the electromagnetic flowmeter is relatively large, usually no less than 20, and the instrument with automatic range switching function can exceed 50~100. The caliber of finalized products available in China ranges from 10mm to 3000mm. However, most of them are small and medium-sized in practical application. Compared with most other principle flow meters (such as volumetric, turbine, vortex street or Coriolis mass), large caliber meters account for a larger proportion.
