The prime mover transmits power to the driving shaft of the pump through a variable speed transmission mechanism, and the driving shaft gear drives the driven shaft gear to move synchronously. The relative movement between the rotor and the pump body changes the working volume, thereby increasing the energy of the liquid, forming a suction cavity, a closed cavity and a discharge cavity.
With the relative movement of the pair of rotors, the pump creates a vacuum in the suction chamber, and the fluid is continuously sucked in, flows through the sealed chamber and is discharged from the discharge chamber to form a flow rate.
The volumetric efficiency of the pump is as high as 98%, the flow rate of the pump is determined by the speed, and the change of its outlet pressure basically does not affect the change of the flow rate. The pressure difference created by the pump depends on the resistance of the discharge system
The nozzle itself has a mechanical structure that can compress the liquid to generate high pressure. When the liquid passes through the perfume nozzle, the low-speed flowing water is compressed, and then suddenly released through the micro-holes of the small nozzle (the principle is similar to the explosion of a bomb), and relatively high-speed movement occurs between the liquid and the air. Tear into small drops. A drop. These small water droplets will turn into fog after being sprayed.
Some friends worry that the perfume will evaporate quickly after putting it on, but this is not necessary.
The design of the perfume nozzle can effectively prevent volatilization because the contact surface between the liquid and the air in the nozzle is very small. The design of most nozzles can also prevent contact with air. The outer cap of the perfume is closed to surround the nozzle. At this time, the fluidity of the air around the nozzle is reduced, so the volatilization is very low. After calculation, only a small part of the nozzle hole of the nozzle device will evaporate, so there is no need to worry too much about the problem of perfume passing through the nozzle and volatilizing.
Of course, if you unscrew the bottle cap, you can use it, like Cologne perfume, if you don't close the bottle cap, it will quickly evaporate in the air.
