Detailed GM Series Membrane Metering Pump - Merton Roll Metering Pump Working Principle - Features 1 Merton Metering Pump General Information 1.1 GM Series Membrane Metering Pump is reciprocating compound dosing pump, the delivery flow of 500L / h, pressure Up to 12Bar. This pump features a mechanically actuated diaphragm that removes the material-side diaphragm guard. 1.2 stroke adjustment mechanism Based on the working principle of variable eccentric mechanism, replacing the traditional design of effective stroke adjustment. This design significantly reduces the degree of pressure and flow pulse. Within 10% - 100% of the flow range, the stability of the accuracy of the flow rate of ± 2%. 1.3 GM pump and pump components as shown below: Including motor, mechanical drive mechanism, pump head. The oil seal between pump head and mechanical drive ensures no leakage of gear oil. 1.4 stroke adjustment handle can manually adjust the flow. 2 Milton Roller metering pump works GM pump consists of two parts, the drive end and the pump head. The output flow depends on the stroke speed at the drive end, pump head size and stroke length. Whether the pump is running or stopped, the stroke length can be changed by adjusting the stroke adjusting handle, and the driving end works according to the principle of the variable eccentric mechanism. The motor decelerates through the worm (1) and the worm wheel (2) to drive the eccentric mechanism, and the eccentric mechanism converts the rotational movement of the worm wheel into the linear reciprocating movement of the connecting rod (4). When the stroke is 0%, the connecting rod shaft (B) is aligned with the worm shaft (A) so that the connecting rod does not reciprocate linearly. When the stroke is 100%, there is an eccentricity between the rod axis (B) and the worm axis (A), resulting in a linear motion of the rod. Diaphragm assembly and the connecting rod mechanically connected to the connecting rod at the same time a straight line reciprocating motion. During the suction stroke, the diaphragm begins to move backwards and the pressure in the pump head decreases. When the pump head pressure drops below the suction line pressure, the suction check ball is pushed "up" and the medium in the inlet line Into the pump head chamber. When the suction stroke is over, diaphragm movement stops instantly. The pressure in the pump head is the same as the pressure in the inlet line and the suction check valve is reset. At the discharge stroke, the diaphragm begins to move forward and the pressure in the pump head rises immediately. When the pump head pressure is higher than the outlet line pressure, the outlet check valve is pushed upward to "push" the medium in the pump head into the outlet line. When the discharge stroke ends, the diaphragm stops once more, the pressure in the pump head is the same as the pressure in the outlet line, and the outlet check valve is reset. Then start the next cycle. 3 米顿罗 metering pumps Product Features 3.1 Mechanical diaphragm pump head, diaphragm and plunger directly connected to promote the plunger plunger material dosing. 3.2 High-performance diaphragm pump head using patented MARS technology (automatic mechanical charging system). 3.3 High-Performance Pump Head The material-backed diaphragm guard for a conventional hydraulic diaphragm pump is eliminated, giving the pump head the "direct passage" of the tubular diaphragm and the low NPSH (net positive suction head) requirement of the piston pump characteristic. 3.4 pump head seal groove design, without additional sealing. 3.5 High-precision one-way check valve to ensure the accuracy of all flow conditions; Self-cleaning check valve structure to ensure that the normal work under harsh conditions.
