The grinding oil filtering system of gear grinding machine belongs to a kind of negative pressure filter. The filtration form of the product produced by our company is negative pressure paper belt filtration, the medium used is grinding oil. What should be paid attention to in the process of its use? Following the negative pressure filter factory manager to have a look!
1. Use atmospheric pressure to make the liquid pass through the filter layer, the dirty liquid enters the dirty liquid tank with mesh plate at the bottom, the vacuum chamber is located under the dirty liquid tank. A recyclable filter belt disposable filter paper is placed between the dirty liquid tank the vacuum chamber to filter the solid particles. The centrifugal pump pumps out liquid the vacuum chamber for machine tools. Vacuum negative pressure filtration device can provide filtration liquid supply functions at the same time.
2. The accumulation of porous filter cake on the filter media is helpful to enhance the ability of capturing particles improve the filtration efficiency. With the increase of impurities in the filter medium, the passing velocity of the liquid decreases the vacuum degree of the vacuum chamber changes. When the true space changes to the preset value, the PLC controls to start the regeneration cycle automatically. In this process, the liquid supply of the pump is affected, the new filter medium is input by the conveyor belt, the dirty filter medium is discharged. Due to the short cycle time of each renewal, only a small piece of filter media is discharged, a large number of filter cakes which can enhance the filtering effect are retained, which can continuously ensure the filtering quality. The seal between the dirty liquid tank the vacuum chamber is a simple reliable hydraulic seal without maintenance.
3. The transmission mechanism is only used to transport the used filter media impurities. The robust design can meet the heavy load transmission save the liquid consumption, because the filter medium regeneration travel time is short, the liquid has enough time to return. The characteristics of solid impurities, permeability, liquid cleanliness cost considerations are very important for the selection of vacuum negative pressure filter gravity paper tape filter.
The above is the characteristics of the negative pressure filter, do you heart? Negative pressure filter which home is good? Yantai Jinchang filtration machinery is very good!
