Precautions for the 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 adjust the gap between the impeller and the guard plate in time.
2. Add an appropriate amount of grease during operation.
3. If the foam pump is not used for a long time, turn the bearing 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 the water for as long as possible, clean the mud flowing through the pump, and then close the inlet gate valve and the outlet valve in turn.
Before the invention of the foam pump, aerosol products were usually used to spray foam, that is, using liquefied gas to expand the spray to form foam, or using a post-foaming agent to make the sprayed colloid form foam. The characteristic of the acupressure foam pump is that the pump body consists of two parts: 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, not affected by the consumer's method of use, and the foam quality is good.
Compared with foam aerosol products, acupressure foam pumps have several distinct advantages: First, it does not require propellant filling, does not pollute the environment, has no flammable and explosive hazards, and does not require metal containers and airtight inflatable equipment , so the cost is low and can be reused; secondly, most of the liquid formulations of the acupressure foam pump are water-based, which are essentially non-volatile organic compounds (VOCs), which are worthy of promotion. Third, containers of various shapes can be used, including square, triangular, oval, etc. In addition, there is no pressure before the container is used, and the choice of container material is wide.
