AzumaDr. Mechanical Diaphragm Metering Pump Structure and Working PrincipleAzumaDr.diaphragm metering pump with special design and processing of flexible diaphragm instead of piston, in the role of the driving mechanism to achieve reciprocating movement, complete the suction, discharge process. AzumaDr.mechanical diaphragm metering pump can be widely used in petroleum, chemical, textile, food, paper, atomic energy technology, power plant, plastic, pharmaceutical, water plant, environmental protection and other industrial and scientific and technological departments. It is used to accurately and quantitatively transfer liquids without solid particles into pressurized or atmospheric vessels and pipelines. And the AzumaDr. dosing pump's flow can be adjust from 1-100% during stop or running.
a. AzumaDr. Dosing Pump structure: The pump is composed of motor, transmission box, body and other spare parts. 1) transmission box parts are composed of CAM mechanism, travel adjustment mechanism and speed ratio worm gear mechanism; Adjust by rotating the regulating handwheel 2) Cylinder body parts are composed of pump head, suction valve group, discharge valve group, diaphragm diaphragm base, etc. b. Working principle When the diaphragm moves backward (namely, suction stroke), the pressure inside the pump head is reduced. When the pump head pressure is lower than the suction line pressure, the inlet check valve will be “pushed” upwards, allowing the medium contained in the inlet line to enter the pump head cavity. At the end of the suction stroke, the diaphragm motion stops instantly. When the pump head pressure is equal to the inlet line pressure, the inlet check valve ball will be reset. In discharge stroke, the diaphragm ,which connected with slide bar starts to move forward, and the pump head pressure rises instantly. When the pump head pressure is higher than the outlet line pressure, the outlet check valve ball will be “pushed” upwards, allowing the medium contained in the pump head to enter the discharge line, then the suction stroke is complete. c. Flow Adjustment Features: The flow adjustment of AzumaDr. pump is to adjust the flow of the hand wheel by rotating the adjusting hand wheel, thereby changing the spacing between the tappets and changing the movement of the diaphragm in the pump cavity to determine the flow rate. Adjusting the scale of the handwheel determines the stroke of the diaphragm with an accuracy of 95%. d. Selection Requirements According to the requirements of different occasions, how to properly select various types of AzumaDr. metering pumps is very important. 1) The capacity of the liquid , the accuracy of the AzumaDr. Pump. 2) Main characteristics of the liquid to be metered, such as chemical corrosivity, viscosity, concentration and density. 3) Back pressure of the system. 4) Suitable suction height. 5) Other options required, such as pulse volume control, flow monitoring and timers. 6) Environmental requirements for equipment, etc. For more information on metering pumps, please click: www.azumadr.com
