A11VO95DR/10+A4VG90DA2/32力士乐柱塞泵的工作原理
柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动,使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点,被广泛应用于高压、大流量和流量需要调节的场合,诸如液压机、工程机械和船舶中。
柱塞泵是往复泵的一种,属于体积泵,其柱塞靠泵轴的偏心转动驱动,往复运动,其吸入和排出阀都是单向阀。当柱塞外拉时,工作室内压力降低,出口阀关闭,低于进口压力时,进口阀打开,液体进入;柱塞内推时,工作室压力升高,进口阀关闭,高于出口压力时,出口阀打开,液体排出。当传动轴带动缸体旋转时,斜盘将柱塞从缸体中拉出或推回,完成吸排油。

如果供给工厂的水量充足,温度较低,成本也较低,此时就不需要使用冷水机,这一般是不太现实的,除非工厂能在水温比较低的大湖边;另一种是利用城市深井供水来满足温度和流量的需要,但往往成本太高。对实验装置可以使用这种方法,但对于工厂,这样做是不切实际的。二.冰水温差模具冷却流体(冰水)的温度一般受制于加工材料和制品形状而发生较大变化,如聚苯薄壁烧杯,模具要求冰水温度在℃以下;而其它绝大多数情况下,模具所要求的冰水的温度都在5℃以上,微电脑全功能冷水机能提供5℃以上的冰水,低温型智能温控冷水机能满足5℃以下及至℃以下的要求。
