Principle and important function parameters of Lotion Pump
First, the working principle of Lotion Pump
01 First pressing
First pressing the head, the head through the connection of the connecting rod to drive the piston head together with the compression of the spring; in the process of compressing the spring, the outer wall of the piston through the inner cavity of the cylinder wall friction, prompting the piston to open the head of the piston discharge holes; piston downward sliding the cylinder through the air has been opened to the head of the piston discharge holes discharged.
02 Reciprocal pressing
Press repeatedly to discharge all the air in the cylinder.
03 Suction
After pressing the head by hand through the connecting rod, piston head and piston, which together compress the spring to discharge the air inside the cylinder, release the head, the spring moves back (up) due to loss of pressure, at this time the piston likewise moves downward by rubbing against the inner wall of the cylinder and closes the discharge hole of the piston head. At this time, the liquid storage chamber in the cylinder forms a vacuum suction state, and the ball valve is sucked upward, and the liquid in the bottle is sucked into the liquid storage chamber of the cylinder through the suction pipe.(plastic lotion pump suppliers)
04 Store liquid
Press the head several times to store the liquid into the cylinder by suctioning the liquid several times until the liquid is stored full.
05 Discharge
When the liquid in the cylinder storage cavity is full, press the betting head again and the liquid will be sprayed out through the discharge hole directly from the betting head press nozzle.
Second, the performance parameters of the Lotion Pump
01 pumping volume pumping
volume is the first important parameter of the Lotion Pump. With the pump head seal, parts tolerance and many other factors.
Calculation method can refer to the following chart:
02 air pressure times / first spray times
Air pressure times / first spray times is another important consumer experience of the parameters, but also an important quality standard in the production process.
The principle is shown in the following diagram:
03 Minimum downforce
Minimum downforce is a factor that is particularly valued by the premium market.
The test principle is shown in the following figure:
04 Leakage function design
Leakage function design is the most important Lotion Pump parameter. Sealing, which seems to be a parameter requirement, involves all the interconnected parts of the Lotion Pump structure.
The following two charts are two different structures of Lotion Pump main sealing key points:
Lotion Pump sealing design points
Guangdong HongYuan, as a manufacturer of Lotion Pumps and plastic bottles, in addition to controlling some of the main functions and parameters, but also for different customer needs to increase a number of additional functions, as well as some of the features of the new design, in order to attract the attention of the end customers, the formation of a new point of growth in profits. Such as: head opening torque control, head and piston rod disengagement force control, head rebound time, anti-water features, anti-counterfeiting features, spring external structure Lotion Pump and so on.
