Pay attention to using foam pump

Precautions for use of foam 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 timely adjust the clearance between the impeller and the guard plate.
2. Add proper lubricating grease during operation.
3. If the foam pump is not used for a long time, rotate the bearing by hand for 1/4 circle every week to make the bearing bear the static load and external vibration evenly.
4. Before stopping the pump, let the pump wash water as long as possible to clean the mud flowing through the pump, and then close the inlet gate valve and outlet valve in turn.
Before the invention of foam pump, aerosol products were usually used to spray foam, that is, liquefied gas was used to expand the spray to form foam, or post foaming agent was used to make the sprayed colloid form foam. The feature of the finger pressure foam pump is that the pump body consists of an air pump and a liquid pump. The liquid is fully mixed with air in the pump body and then ejected. The spraying amount is stable, the operation is simple, and it is not affected by the use method of consumers. The foam is of good quality. Compared with foam aerosol products, the finger pressure foam pump has several obvious advantages: first, it does not need to be filled with propellant, does not pollute the environment, has no danger of flammability and explosion, does not need metal containers and sealed inflation equipment, so it has low cost and can be reused; Secondly, the liquid formula of the finger pressure foam pump is mostly water-based, essentially nonvolatile organic compounds (VOCs), which is worth promoting. Third, containers of various shapes can be used, including square, triangle, ellipse, etc. In addition, there is no pressure before the container is used, and the selection range of container materials is wide.
