The reasons and inspection methods for not bouncing back after pressing the emulsion pump head
In order to prevent this kind of situation, in the production process, our first probably test spring length is not standard, miss a mile, the effect of the length of the piston is not ignored, if short, then will form the piston return is not in place, directly formed after pressing the head down, can not rebound or rebound slower.
Secondly, the thickness of the piston is detected whether it fits the body. In the movement of the piston, any open space will form inspiratory weakness, and the material body can not be pressed according to the head. Because plastic has the properties of thermal expansion and contraction, a normal piston is appropriately important to ensure the quality of the emulsion pump head.
Finally, let's analyze the body, in view of the elastic characteristics of plastic, if the injection time is not appropriate, the lack of injection glue will cut off a thin layer of the body, resulting in uneven inner wall, the piston stamping process can not prevent the gap, so that can not be discharged.
After the analysis of the above three parts, it can not be pressed out. Perhaps the appearance that the head can not bounce can be prevented after pressing.
