Positive displacement pumps can be divided into two major categories: reciprocating and rotating. Reciprocating pumps include steam pumps and power pumps. Many reciprocating pumps use a flexible membrane or diaphragm and are collectively called diaphragm pumps. They are of various types and come in a...
When it comes to positive displacement pumps, the toughest choice an operator has is deciding which one will work best in their application. It’s not always a simple choice either, as positive displacement pump technologies offer many of the same benefits and varying advantages. For operators, ...
正排量泵（Positive Displacement Pumps）主要用于一些特殊应用，例如泵送粘性液体或含有悬浮颗粒或易碎固体的液体。这些泵通常无法像离心泵那样实现高流量，但它们能够产生更高的压力。正排量泵的工作原理 正排量泵通过捕获固定体积的流体并将其强制（排量）到排出管道或系统中来实现流体的移动。一些正排量泵在吸入侧使用...
