Product Introduction
Overview:
Metering pump is a volumetric, mechanically operated reciprocating metering pump. Widely used in petroleum, chemical, food, pharmaceutical, papermaking, light industry, agriculture, water plant environmental protection and other industrial and scientific and technological sectors, in the process of measuring all kinds of media in the process and the task of adding. According to the different media needs to choose different liquid end material, the standard configuration for the PVC material, choose to configure 304, 316, PVDF and other materials.
GCM/GWM/GXM/GZM series metering pumps can be transported at temperatures of -15 ℃ ~ 60 ℃, viscosity 0.3 ~ 1000cps without solid particles and other corrosive or non-corrosive liquid media. The rated displacement of the pump is in the range of 10~3600L/h, and the corresponding maximum output pressure is 1.2~0.3MPa. The outlet displacement of the pump can be adjusted by adjusting the size of the rotating handwheel, regardless of whether the pump is in operation or not, 0%~100% is adjustable, and the adjusting knob can also be locked. In the range of 30%~100% flow rate, the steady state accuracy is ±1%. It is a metering pump with a simple structure, low energy consumption, accurate metering, and practicality.
GCM/GWM model metering pumps can be equipped with 220V or 380V motors on request.
CXMGZM model metering pumps can be equipped with explosion-proof motors or frequency conversion motors according to requirements.
Pump model specifications and parameters, please refer to the company's product selection samples.
Pump structure and principle:
The pump consists of two main parts: the transmission end part and the hydraulic end (pump head) part. The output flow of the pump depends on the stroke speed of the drive end, the diaphragm (pump head) diameter and diaphragm stroke length. When the pump is running or stopped, the stroke length can be changed by adjusting the stroke adjusting handwheel. The transmission mechanism works according to the principle of variable eccentric mechanism, i.e., the motor rotates to drive the worm gear for deceleration, and the variable eccentric is driven to rotate by the shaft by the worm gear reducer part, and the adjustable eccentric crankshaft transmits reciprocating motion to the diaphragm through the connecting rod, which produces a flexural deformation of the diaphragm. By changing the position of the variable eccentric crankshaft on the connecting rod, the stroke length can be adjusted. Spring in the suction stroke, the diaphragm began to move backward, the pump head pressure is immediately reduced: when the pump head pressure is lower than the suction line pressure, the suction port check valve valve ball is pushed upward “open”, the medium in the inlet pipeline into the pump head chamber. When the end of the suction stroke, the diaphragm movement stops instantly, the pressure in the pump head and the suction line pressure is equal, the suction port check valve ball reset.
Pump in the discharge stroke when the diaphragm began to move forward, the pressure in the pump head rises immediately. When the pump head pressure is higher than the discharge line pressure, the discharge check valve ball is upward “push open”, the pump head of the liquid into the discharge line, when the discharge stroke ends, the diaphragm once again instantly stop moving. The pressure inside the pump head is the same as the pressure in the discharge line, the discharge check valve ball reset, and then start the next cycle.
In the suction stroke, the pressure inside the pump head must be higher than the material vapor pressure; if the liquid pressure is lower than its vaporization pressure, air pockets will occur, affecting the performance of the poly.
