316SS pump head
The metering pump, also known as the proportional pump, is a convenient and accurate way to change the stroke of the embolism by adjusting the eccentric distance of the eccentric wheel.
Metering pump is also called quantitative pump or proportional pump. Metering pump is a kind of special volume pump, which can meet the needs of all kinds of strict process flow, and the flow can be stepless adjusted in the range of 0-100%. It is used to transport liquid (especially corrosive liquid).
Metering pump is a kind of fluid conveying machinery, its outstanding feature is that it can maintain a constant flow independent of discharge pressure. The metering pump can complete the functions of transportation, metering and adjustment at the same time, so as to simplify the production process. Using multiple metering pumps, several kinds of media can be input into the process flow according to the accurate proportion for mixing. Because of its own outstanding, metering pump has been widely used in petrochemical, pharmaceutical, food and other industrial fields.
The motor drives the worm through the coupling and decelerates the worm gear to make the main shaft and the eccentric wheel rotate. The eccentric wheel drives the sliding adjustment seat of the bow connecting rod to make reciprocating motion. When the plunger moves back to the dead center, a vacuum is gradually formed in the pump cavity, the suction valve is opened, and the liquid is inhaled; When the plunger moves forward to the dead center, the suction valve is closed and the discharge valve is opened, and the liquid is discharged when the plunger moves further. In the reciprocating circulation of the pump, continuous pressure and quantitative discharge liquid are formed.
