涡扇风冷螺杆泵
本技术涉及一种真空螺杆泵,尤其涉及一种涡扇风冷螺杆泵。
技术介绍
目前在真空泵领域中,螺杆泵工作产生的高温主要有自然冷却,风冷和水冷几种散热方式解决设备系统的散热问题,尤其以自然冷却和水冷为主。在实际设计过程中,考虑到低碳,环保的设计理念,对散热的热流走向,资源相对忽略,从而导致散热降温,能源利用不进合理,完善:1.采用单一的大风量的风机可以一定程度上降低控制系统表面的温升,但是这种方式并不能解决系统内的温度差异问题;病在膏盲,治标不本。2.单一用水冷却:固定容量的循环水,泵体高温运行一段时间后,水温上升,降温效果就会降低;大量的冷却水,一是资源浪费,二是泵体内冷却容腔,管径受限,冷却水中含有一定的重金属,杂质,长期以来会沉积腔体,堵塞管路,降低冷却效果。所以说,该两种冷却方式都不能从根本上改善螺杆泵散热效果,降低系统内的温升。这样不仅不能降低生产成本,还降低了螺杆真空泵的使用寿命,同时还无形中增加了不确定性的安全隐患。
