Analysis of the working principle of metering pump
As a kind of common water pump, metering pump is a kind of pump that can meet a variety of strict process needs, the flow can be 0- 100% range of stepless adjustment, used to transport liquids (especially corrosive liquids). It can be said that the merit of metering pumps is very prominent, but do we know the working principle of metering pumps? Xiaobian to come briefly to introduce. Metering pump metering pump is divided into electromagnetic diaphragm metering pumps, mechanical diaphragm metering pumps, piston metering pumps and hydraulic diaphragm metering pumps. The motor is driven by a coupling through a worm and the worm gear to slow down the spindle and the eccentric rotation for the rotation, driven by the eccentric bow arch link, connecting rod driven crosshead, crosshead driven plunger reciprocating operation to achieve the media inhalation and discharge . When the plunger moves backward, a vacuum is gradually formed in the pump chamber, the suction valve is opened, and liquid is sucked in. When the plunger moves forward, the suction valve is closed and the discharge valve is opened, and the liquid is discharged when the plunger moves further. In the pump reciprocating work to form a continuous pressure, the amount of liquid discharge. Diaphragm metering pump works the same principle, there is a diaphragm between the plunger and the media, the cavity between the plunger and the diaphragm is called the hydraulic chamber, the need to inject hydraulic oil, diaphragm and cylinder chamber called the flow chamber When the plunger reciprocates, the plunger pushes the hydraulic oil and the hydraulic oil actuates the diaphragm to reciprocate to achieve the work.
