上海供应美国威格士VICKERS柱塞泵

理论上，泵的流量只取决于泵的主要结构参数　n（每分钟往复次数）、S（活塞行程）、D（活塞直径）、Z（活塞数目），与排出压力无关，且与输送介质的温度、粘度等物理、化学性质无关。所以说泵的流量是恒定的。
3.泵的压力取决于管道特性
柱塞泵的排出压力不能由泵本身限定，而是取决于泵装置的管道特性，并且与流量无关。也就是说，如果认为输送液体是不可压缩的，那么，在理论上可认为往复泵的排出压力将不受任何限制，即可根据泵装置的管道特性，建立泵的任何所需的排出压力。当然，所有往复泵都有一个泵的排出压力的规定，这不是说该泵的排出压力不会再升高，而只是说，由于原动机额定功率和泵本身的结构强度的限制，不允许在超出这一排出压力下使用而己。

4.对输送介质有较强的适应性
　　柱塞泵原则上可以输送任何介质，几乎不受介质的物理性能和化学性能的限制。当然，由于液力端的材料和制造工艺以及密封技术的限制，有时也会遇到不能适应的情况。
　　5.有良好的自吸性能
　　柱塞泵不仅有良好的吸入性能，而且还有良好的自吸性能。因此，对多数往复泵来说，在启动前通常不需灌泵。 机器效率高，节能。
　　6.高压柱塞泵的流量
　　泵的理论流量：Qt=AsnZ
