Before the invention of the foam pump, the foam was usually sprayed by aerosol products, that is, the spray was expanded to form a foam with liquefied gas, or the sprayed colloid was used to form a foam with a post-foaming agent. The characteristic of the acupressure foam pump is that its pump body is composed of an air pump and a liquid pump. After the liquid is fully mixed with the air in the pump body, it is sprayed out. The spray volume is stable, the operation is simple, and the foam quality is good. The following are the precautions for the use of a Lotion Pump :

1. First, pay attention to the adjustment of the impeller. In order to ensure the efficient operation of the pump, it is necessary to adjust the gap between the impeller and the guard plate in time.

2. During operation, add an appropriate amount of grease.

3. If the foam pump is not used for a long time, the bearing should be rotated 1/4 turn by hand every week, so that the bearing can bear the static load and external vibration evenly.

4. Before stopping the pump, let the pump clean water for a period of time as much as possible to clean the slurry flowing through the pump and then close the inlet gate valve and the outlet valve in turn.
