First, let's look at the working principle of vacuum pump. Vacuum pump is a device that produces negative pressure, and the system is in a vacuum state by removing air. In the ceramic filter, the vacuum pump mainly absorbs the air in the filter and provides the vacuum needed in the filtering process. When the vacuum pump starts to work, air is pumped out of the filter through the exhaust pipe to form negative pressure. This negative pressure can keep the solid particles in the liquid on the filter through the small holes on the filter and discharge the clean liquid through the filter. Vacuum pump is usually driven by motor, which generates negative pressure by mechanical or liquid means to meet the requirements of filter adsorption and vacuum supply.
Next, the working principle of filtrate pump. The filtrate pump is used to discharge the filtrate from the filter to ensure the smooth filtration process. The filtrate pump in ceramic filter usually works mechanically. It sucks the filtrate in the filter into the pump and then draws it out through the drainage pipe for further treatment or collection.
Generally speaking, the working principles of vacuum pump and filtrate pump in ceramic filter cooperate with each other. The vacuum pump maintains the adsorption and vacuum requirements in the filtration process by generating negative pressure, while the filtrate pump is responsible for discharging the filtrate from the filter. The cooperation of these two pumps enables the ceramic filter to complete the liquid-solid separation process efficiently.
