Product Description: Operation of Plate Heat Exchanger1. Startup Operation and Precautions(1) When using a new process pipeline, ensure the removal of debris within the pipeline to prevent clogging the heat exchanger.(2) If using sewage as a cooling medium, recovering waste heat from sewage, or if the medium contains granular solids, install a filter or dirt separator at the inlet of the heat exchanger to avoid clogging.(3) When the temperature of the cooling water (being heated) exceeds 40°C, softening treatment should be performed as much as possible to prevent scaling in the heat exchanger, which could affect heat transfer efficiency.(4) Check whether the pipeline connections are correct to avoid mixing of the two media, which could lead to adverse consequences.(5) Before startup, strictly inspect whether the inlet valves for the cold and hot media are closed and the outlet valves are open.(6) After completing the above steps, the system can be started. Begin by starting the pumps for the cold and hot media, slowly open the inlet valve for the cold medium, and then open the inlet valve for the hot medium to allow the media to flow slowly into the heat exchanger, preventing excessively high temperatures.(7) Check all sealing surfaces and welded joints for any leaks or abnormal phenomena.(8) Gradually increase the temperature while measuring and calculating whether the process requirements are met. Once satisfied, proceed to normal operation. more>

Product Description: 树枝粉碎机是用于将树干或树枝粉碎成木屑的一种机械设备，其主体部分由装在同一轴上的盘和多组锤片组成。粉碎机上有两个进料口，一个靠近盘侧，是树干的进口；另一个在锤片组的前方，是树枝的进料口。因为树枝较细，可不经盘削片直接送入锤片区打碎。目前，市场上的树枝粉碎机大多只是在锤片区前方设置一个简单的进料口；在依靠人工投入树枝、尤其是枝桠杈时，由于缺乏继续进给的动力，经常出现树枝难以顺利送入的现象，进料速度慢，严重影响树枝粉碎的生产效率。另外，也有部分树枝粉碎机虽然设置了液压驱动的进料辅助装置，但因为这类液压装置需要装备相应的液压传动系统（包括油泵、油箱、液压缸等），所以导致整个进料辅助装置的结构过于复杂、体积庞大，制造成本高，不利于装置的使用推广。故有必要对现有技术的树枝粉碎机进料辅助装置予以改进。 more>
