Customizable Water Treatment Pumping System - Metering Pump
1 . Descriptions:
Metering pumps are special pumps that can accurately deliver liquids and are used in a variety of industrial fields, including wastewater treatment systems and pure water treatment systems, where precise control of liquid flow is required. The working principle of metering pumps is that the diaphragm or piston is driven by the drive mechanism to carry out reciprocating motion to change the volume of the pump chamber, thus accurately delivering the liquid. The drive mechanism is usually driven by an electric motor or pneumatic device, and the working cycle of the pump is controlled by a mechanical or hydraulic transmission system.
In the suction phase, the diaphragm or piston retracts, increasing the volume of the pump chamber, forming negative pressure, and allowing liquid to enter the pump chamber through a check valve. In the discharge phase, the diaphragm or piston moves forward, decreasing the volume of the pump chamber, and the liquid is discharged through another check valve. The flow rate of the metering pump can be accurately adjusted by the adjusting screw or electronic controller to ensure that the flow rate of the conveyed liquid is precisely controlled, and the error is usually within ±1%. Wastewater treatment systems and pure water treatment systems rely heavily on such precision for consistent operation.
