摘要
计量泵分为柱塞泵、隔膜泵和齿轮泵等多种形式,广泛应用于石油化工等领域。其中液压驱动隔膜计量泵以其无泄漏、可靠性高的特点被某工程塑料装置选用。技术人员在使用过程中通过解决出口压力大幅波动和出口无流量等故障熟悉了解了该型泵的结构特点。
There are many types of pump which can be used as metering pump like piston metering pump, diaphragm pump, gear pumps and so on. Metering pump is widely used in petrochemical field. Hydraulic-driven diaphragm metering pump has the characteristics of no leakage and high reliability. So this type of pump is selected by an engineering plastic plant. Technical staff get familiar with the structure and characteristics of the pump by solving discharge pressure fluctuation and no flow problems.
