understand the emulsion pump

First, understand the emulsion pump

The emulsion pump uses the principle of atmospheric balance to pump out the raw material liquid in the bottle by pushing and pressing, and adds the external atmosphere to the liquid dispenser in the bottle. The main performance indicators of the emulsion pump are: the number of air pressure, the pump displacement, low pressure, the opening torque of the nozzle, the rebound speed, and the amount of water in the bottle.

The size of the pump head is determined by the diameter consistent with the bottle, the spray specification is 12.5mm - 24mm, the water yield is 0.1ml/ time - 0.2ml/ time, generally used for perfume, gel water and other product packaging, the caliber is the same, the length of the handover can be determined by the height of the bottle.

The emulsion pump specifications range from 16ml to 38ml, and the water yield is 0.28ml/ time - 3.1ml/ time, which is generally used for cream and washing products.

Special dispensers, such as foam pump head and manual pump head, foam pump head is a non-inflatable manual pump head, does not need to be inflated to produce foam, just gently press to produce quantitative, high-quality foam, generally have a special bottle, snap nozzle is usually used for detergent and other products.

The structure of the distributor is very complex, generally including dust cover, percussion head, percussion rod, washer, piston, spring, valve, cover, pump body, straw, valve ball (steel ball, glass ball), cover, dust cover can be made of colored, can be electroplated, can be set with electrolyzed aluminum.

Vacuum bottles are usually cylindrical, the specification is 15mL-50ml, there are 100ml, the overall capacity is small, relying on the principle of atmospheric pressure, can avoid pollution in the use of cosmetics, vacuum bottles have electrolytic aluminum, plastic electroplating and colored plastics, the price is higher than other ordinary containers, ordinary orders are not high, customers rarely open their own mold, the need for a lot of molds, the cost is high.

Second, the working principle of the emulsion pump head:

Press the handle by hand, the volume of the spring chamber decreases, the pressure rises, the liquid enters the nozzle chamber through the hole of the valve body, the liquid is sprayed out through the nozzle, at this time, after releasing the handle, the volume of the spring chamber increases, forming negative pressure, the ball opens under the action of negative pressure, the liquid in the bottle enters the spring chamber, at this time there is already a certain amount of liquid in the valve body, when pressing the handle again, The liquid stored in the valve body is ejected upward.

From the above working principle, the key to a good emulsion pump head is to pay special attention to the following aspects,

1, the glass or steel ball under the spring, the seal here is very important, and the force of the liquid in the spring chamber is related to the upward thrust, if it leaks from here, a part of the liquid will leak into the bottle when pressing the handle, thus affecting the spray effect of the liquid;

2. The sealing ring at the upper end of the emulsion pump valve body, if there is a leak here, the liquid pulling up force is reduced when the handle is removed, and the amount of liquid stored in the valve body is small, which also affects the spray effect.

3, the emulsion pump lever and the valve body clamp, if the clamp is loose here, there is a leak, the liquid will rise to the nozzle will have a certain resistance, resulting in liquid countercurrent, if the leak from here, will also affect the spray effect.
