近年来,由于石油化工、化工、轻工、纺织等工业的迅速发展,需要处理高粘度液体。在输送高粘度液体时,目前趋向于连续操作。在液体粘度和其它工艺条件变化时,就需要有性能稳定、高压、高精度和自动调节流量的高粘度泵。本文主要介绍往复式高粘液计量泵的试验研究及为了开展这项研究工作而建立的带除气塔的高粘度计量泵试验装置。一、装置建立的根据计量泵的主要经济指标是流量和计量精度,泵流量Q与各影响值之间存在如下的函数
In recent years, due to the rapid development of petrochemical, chemical, light industry, textile and other industries, it needs to deal with high viscosity liquids. In the delivery of highly viscous liquids, the current trend tends to be continuous operation. In the liquid viscosity and other process conditions change, you need to have stable performance, high pressure, high precision and automatically adjust the flow of high viscosity pump. This paper mainly introduces the experimental research of reciprocating mucilage metering pump and the test device of high viscosity metering pump with degassing tower established to carry out this research work. First, the device is set up According to the main economic indicators metering pumps flow and measurement accuracy, pump flow Q and the impact of the following values between the function
