AI Technical Summary
Technical Problem
Existing diaphragm-type metering pumps for dispensing medicine cannot detect diaphragm rupture in a timely manner, resulting in reduced system safety. Furthermore, direct mechanical drive leads to a shortened diaphragm life and a lower upper limit of operating pressure.
Method used
The circular diaphragm is made of polytetrafluoroethylene and equipped with a diaphragm damage sensor and a metering pump. The diaphragm is driven evenly by hydraulic oil. It is equipped with a safety valve and automatic interlock protection function to ensure system safety and extend diaphragm life.
Benefits of technology
It achieves automatic protection in case of diaphragm rupture, extends diaphragm life, and increases the upper limit of working pressure, ensuring safe operation of the system.

Abstract
The utility model relates to the technical field of diaphragm type pumps, and discloses a novel diaphragm type liquid medicine quantitative pump which comprises a middle body, a motor is arranged on the top of the middle body, a pump body is connected to the left end of the middle body, and a coupler is arranged in the middle body. An output shaft of the motor penetrates through the top of the middle body and is connected with a worm through a coupler, an eccentric wheel is arranged in the middle body and located below the worm, an eccentric wheel plug is installed on the eccentric wheel, and one end of the eccentric wheel is connected with a connecting rod. By arranging the diaphragm damage sensor, once the diaphragm is broken, the sensor triggers an automatic linkage protection function to ensure the system safety, the introduction of the metering pump further optimizes the driving mode of the diaphragm, and the pump effectively relieves the problem of concentrated stress of the diaphragm under direct mechanical driving through uniform driving of hydraulic oil, so that the service life of the diaphragm is prolonged. The service life of the diaphragm is prolonged; and the working pressure upper limit is improved.
