Operational Mechanism of a Metering Pump
A metering pump, also known as a fluid metering pump, which is designed to accurately deliver precise amounts of liquid in industrial and chemical applications. The operational mechanism of a metering pump involves a few key components and principles:
- Pumping Mechanism: Metering pumps use a reciprocating or oscillating mechanism to displace and deliver liquid. This mechanism is often driven by a motor or an electromagnetic drive system. The reciprocating motion ensures accurate and controlled dosing.
- Pumping Chamber: The pumping chamber is where the liquid is contained and pressurized. It usually consists of a cylindrical chamber or a diaphragm. The chamber has an inlet and an outlet valve to control the flow of liquid.
- Inlet and Outlet Valves: The inlet and outlet valves regulate the flow of liquid into and out of the pumping chamber. These valves are typically check valves that allow the liquid to flow in one direction while preventing backflow.
- Control Mechanism: These chemical feed pumps incorporate a control mechanism to adjust the stroke length or frequency of the reciprocating motion, which determines the volume of liquid delivered per cycle. This control mechanism can be manual, mechanical, hydraulic, or electronic, depending on the type and sophistication of the pump.
- Adjustment and Monitoring: Chemical injection pump often have mechanisms for adjusting the stroke length, stroke speed, or flow rate to control the precise dosage. Some pumps may include sensors or feedback mechanisms to monitor and maintain the desired flow rate or pressure
- Priming and Pressure Relief: This solenoid metering pump may have priming mechanisms to remove air or gas from the pumping system. They may also incorporate pressure relief valves to protect the pump and the system from excessive pressure buildup.
