DOSING PUMPS hirlrnconta tecnologfa hidrfiulica

DOSING PUMPS Hydrodynamic design The electric dosing pumps are alternate movement pumps. Their flow rate is determined by the alternate movements of the piston, activated by an eccentric or by a crank-shaft rod system. For this alternating movement to be generated on the head when suctioning and discharging, a set of valves is installed that prevent the return of the fluid, making the flow rate intermittent and allowing the frequency to be determined by the number of piston strokes. The valves are spherical and closed by gravity. Theoretical flow rate The theoretical flow rate is equal to the volume...

DOSING PUMPS Operation 1. SUCTION PHASE: During this phase, the piston makes that valve close in the discharge position (due to its weight and the eventual pressure of the fluid), while it opens in the suction position due to the positive pressure generated during the suction phase. The fluid enters the chamber of the head and its volume is equal to that of the piston cylinder capacity. 2. COMPRESSION PHASE: During that phase, the piston makes the valve close in the suction position (as in the above case, due to its weight and the pressure exerted by the fluid); at the same time, the valve opens...
