A set of mechanical motor dosing pump equipped with an intelligent stroke adjuster

High Flow Mechanical Motor Dosing Pumps

Mechanical motor dosing pumps is commonly used for conveying high viscosity media. It is equipped with a spring return check valve to effectively ensure the capacity and linearity of the dosing pump when conveying high viscosity liquids. The electric stroke adjuster installed on the pump allows for precise setting and display of the pump stroke length through the adjuster operation panel. It has significantly higher flow and pressure capabilities than electromagnetic solenoid dosing pumps. Our customers can choose different dosing pumps based on their specific needs.

Working Principle

The motor drives the helical gear reduction box connected with the main shaft to form a reduction mechanical structure. The bearing performs eccentric motion on the eccentric circle of the eccentric shaft, the generated eccentric distance is converted into linear motion of the push road. The push rod drives the diaphragm to do linear reciprocating motion with the cooperation of the restoring force of the spring.

When the push rod pulls the diaphragm to move backward, the volume between the diaphragm and the pump head increases to generate negative pressure. The one-way valve of the suction pipeline opens, and the medium in the inlet pipeline enters the cavity of the pump head. When the suction stroke ends, the diaphragm movement stops instantly, the pressure in the pump head is balanced with the pressure in the inlet pipe, and the one-way valve of the suction port is reset. During the discharge stroke, the diaphragm connected with the slide bar moves forward. When the pump head pressure is higher than the outlet pressure, the outlet check valve is opened, the medium in the pump head enters the discharge line. When the discharge stroke ends, the diaphragm movement stops again, the pressure in the pump head is equal to the outlet pressure, and the outlet check valve resets, and then enters the next cycle.
