Abstract

The invention provides a dosing metering pump, which comprises a base, a stroke control chamber arranged on the base, a liquid medicine circulation pump and a drive motor; the liquid medicine circulation pump is fixedly connected with the outer wall of the stroke control chamber through a fixing connection piece; a liquid medicine passage is arranged in the liquid medicine circulation pump; one end of the liquid medicine passage is provided with a liquid inlet and the other end is provided with a liquid outlet; the side of the liquid medicine passage is provided with an opening, and the opening is sealed with a diaphragm which can be deformed under the action of an external force; a push-pull mechanism is arranged in the stroke control chamber; and the push-pull mechanism comprises a push-pull rod, an eccentric disk, a base shaft and a rotary drive mechanism; one end of the rotary drive mechanism is connected with the drive motor and the other end is connected with the base shaft; theeccentric disk is sleeved on the base shaft; the lengths of two ends of the eccentric disk away from the base shaft are different; the end of the eccentric disk abuts against one end of the push-pullrod, and the other end of the push-pull rod is connected with the diaphragm. The dosing metering pump provided by the invention is used for measuring and adding liquid medicine, and the dosing metering has high precision, stable operation and strong corrosion resistance.

Description

technical field [0001] The present application relates to the technical field of dosing and metering equipment, and in particular, to a dosing and metering pump. Background technique [0002] At present, the dosing metering pump is widely used in various fields including the pharmaceutical, food and beverage and petrochemical industries, and is responsible for the metering and addition of strong corrosive, toxic, high viscosity and high pressure media in the process. With the general improvement of people's requirements for production process indicators and automation, as the final actuator of chemical metering and addition, the safety and controllability of dosing metering pumps have become increasingly important. [0003] As we all know, the dosing metering pump is mainly composed of a pump body, a transmission mechanism, a driving mechanism and a front cover. It is a diaphragm pump, the diaphragm is connected to the transmission mechanism, the transmission mechanism is c...
