33 tooth emulsion pump how much do you know about it? Why doesn't it bounce back after pressing?

To use, we first expel the air in the liquid storage chamber (i.e. the plastic tube that can absorb the emulsion) by pressing the way. When the air is out, press the pump head again. Because the spring in the pump head will return to its original state after release, a vacuum will be formed in the liquid storage chamber, resulting in negative pressure. At this time, the pressure in the container is consistent with atmospheric pressure, resulting in low pressure in the liquid storage chamber and high pressure in the container.

33 The basic functions of the dental emulsion pump are:

1. Sealing function. It is believed that every consumer is unwilling to accept a product whose contents leak from the surface of the bottle. After pump and bottle filling and packaging, sealing function is one of the important requirements to ensure the storage and transportation of bottled products.

With the development of electronic technology and the improvement of automation level, there are standard configuration in the production process of automatic inflatable 33 tooth emulsion pump. As for the parameters in the test method, such as vacuum, time, pressure, air pressure and so on, each company is different according to customer requirements, control parameters are not the same, so I will not repeat.

2. 33 Pumping function of dental emulsion pump. 33 Tooth emulsion pump is characterized by the ability to pump out the same volume of liquid for consumer use, so the pumping function is also one of the important requirements. In the manufacturer, the intuitive method to verify this function is: open the 33 tooth emulsion pump head, and then press the head down to the end of the stroke, plug the inlet of the cylinder shell with the finger of the other hand, release the head to make it spring back naturally, the skin on the finger surface will have the feeling of being sucked (commonly known as "sucking"), and even hang the emulsion pump upside down on the finger. This is one of the main ways for manufacturers to confirm whether the pumping function is intact.

Why can't 33 tooth emulsion bounce back after pump pressure?

In order to avoid this situation, in the production process, the spring length should be checked first. The difference is thousands of miles. The effect of the length on the piston cannot be ignored. If short, the piston return is not in place, directly resulting in indenter can not or slow rebound.

Second, check that the piston is the right thickness for the body. In the movement of the piston, any gap will cause weak suction, and the head will not press the material body. Because plastic expands and contracts in heat and cold, ordinary piston is very important to ensure the quality of emulsion pump.

And then. Let's analyze the bottle body of the 33 tooth emulsion pump. In view of the elasticity of plastic, if plastic injection is not properly operated, it will cut off the thin layer of the body due to insufficient injection, resulting in uneven inner wall, which will inevitably leave gaps in the stamping process of the piston, resulting in discharge failure.
