Dosing metering pump working principle
Dosing metering pump motor driven by the worm and the worm through the worm gear so that the spindle and the eccentric rotation for the rotation, driven by the eccentric tappet in the guide cylinder for reciprocating motion. Together with the diaphragm, the vacuum in the pump cavity is gradually formed by the action of the one-way valve, the suction valve is opened and liquid is sucked in;
When the diaphragm moves forward to the dead point, the suction valve is closed and the discharge valve is opened. The liquid is discharged by the diaphragm. In the pump by adjusting the stroke of a reciprocating work to form a continuous pressure, the amount of liquid discharge.
Use high quality aluminum foil and high strength aluminum pipe to straight pulling expanding pipe, to make fins and pipes combine tightly . Composing professional bending machine for molding, no-clean braze technology, high pressure leakage test, fluoride-free clean, degrease painting,nitorgen protection. The All Aluminum Evaporator & condenser has high heat exchange performance , light , less welding points and etc.. Our craft processing of inner cleanness and anti-corrosion is the most advanced over the world . Which is widely applied in HFC, CFC and etc.. refrigerants.
