Abstract

The invention relates to the field of fluid conveying and metering equipment, in particular relates to an electric metering plunger pump, and aims at replacing the traditional fluid conveying and metering mode that is performed through the combination of a pneumatic plunger pump and a flow instrument. The electric metering plunger pump is characterized in that the metering plunger pump is stably driven through a stepping motor; the volume of the conveyed fluid is metered according to the volume of a cavity of a metering pump body. According to the electric metering plunger pump, the fluid conveying and metering functions are combined, thus both low-viscosity fluid conveying and metering and high-viscosity fluid conveying and metering apply; meanwhile, the shortcomings of complex structure, high cost, high requirements on mounting conditions and the like of the prior art are overcome; a system with high competitiveness on technology and cost is brought; a completely new solution is brought to the conveying, metering and coating of high-viscosity fluid; the applicable scope is wide; commercial popularization and application are easily carried out.

Description

technical field [0001] The invention relates to the field of fluid delivery and metering equipment, in particular to an electric metering plunger pump. Background technique [0002] The transportation and measurement of traditional high-viscosity fluids mostly use pneumatic plunger pumps and flow meters. The Chinese patent application with application number 201120030944.5 discloses a typical pneumatic plunger pump. Due to the instability of using gas as power, the pneumatic plunger pump can only be used for transportation and is difficult to be used for metering. In occasions where precise metering is required, a pneumatic plunger pump is often equipped with a flow meter, and the two can be used simultaneously to achieve the purpose. Most of the flowmeters in the prior art are not suitable for high-viscosity fluids; although a small number of high-tech flowmeters produced abroad are suitable for some high-viscosity fluids, not only the installation conditions are harsh, bu...
