真空泵抽不上水原因
真空泵在作为真空泵引水使用过程中,由于操作不当而引起抽不上水,上海飞鲁总结多年的实践经验,将不上水的原因总结为以下几点。
真空泵常用性能参数详注
真空泵的抽气速率和极限压力两个参量是在实际应用中选配真空泵的最重要的参量。
真空泵操作注意事项
真空系统启动时,要先用机械泵将系统抽至低真空,再接通扩散泵冷凝水.然后逐渐加热使油沸腾并正常回流后再启动油扩散泵。
真空泵操作要点
水环泵运转时,要不断地充水以维持泵内液封,同时也起冷却的作用,但泵所能造成的真空度受泵体中水的温度所限制。
爪式泵的性能
一般的无油干式泵和油封机械泵相比,其压缩比较小,要克服高的压力差,向大气直接排气,还需要抽除大量的颗粒物,因此选择有效地抽气机构是非常重要的。
爪式泵的特点
爪式泵是为半导体工业发展而研制的,它有如下一些特点。
怎样用制冷系统中的压缩机抽真空
采用空调制冷系统的压缩机对制冷系统抽真空.这种方法简便、易行,只是真空度不高。但在没有抽真空设备的情况下,还是被广泛采用。具体操作方法如下。
怎样给真空泵安装合适的真空管路
真空管路是真空泵真空挤出机的重要组成部分,主要包括安装于真空泵进气管路的空气过滤器(如气、油、水分离器)、安装于真空泵排气口的消声器及真空表等真空管路。
