重型挤压泵是从普通的蠕动泵原理发展起来的。而七十年代后期开始,国外大容量、高压头的重型挤压泵不断投入市场。主要用来采矿、冶金行业的重质、高浓度、高粘度矿砂浆,在市政环境保护方面转运,排放污水污浆,在化工行业对有腐蚀性或要求高纯度不得溅漏的高粘度化学液体也特别适用,在建筑行业可进行灰浆的喷涂,混凝土施工高层运送。 Heavy-duty pump is developed from the principle of ordinary peristaltic pump. The late seventies, foreign large-capacity, high-pressure heavy-duty pump continuously into the market. Mainly used for mining, metallurgical industry of heavy, high concentration, high viscosity mineral mortar, municipal environmental protection in the transport, discharge of sewage sludge in the chemical industry for corrosive or require high purity splashed high viscosity chemical liquid Also particularly suitable for the construction industry can be mortar spraying, concrete construction of high-level delivery.
