automatic online cleaning filter ( SQ type) Because of its high efficiency and convenient and is widely used in drinking water, alcohol, oil, oil, chemical industry, etc, when the liquid containing solid impurities, filter through the inlet into the automatic flushing, impurities trapped in the filter element surface, causes the pressure drop increases, filtration resistance increases, filtration efficiency decline. When impurities trapped reaches a certain degree, the pressure difference on both sides of the filter element to set data, differential pressure controller through the controller and the corresponding signal to electric valve actuator, electric valve opens, under the hydraulic or electric motor drive, blowdown. After a period of time that filter differential pressure decreases, and import and export of electric valve automatically shut down, to complete the processing. This process is repeated to filtering effect. My company produces automatic flush filter can according to customer's specific requirements ( Differential pressure control and time control, manual control, etc. ) Custom.
automatic stripping system:
after impurities clogging filter channel, automatic stripping system startup, shave their mesh surface impurities achieve mesh regeneration, impurity collection storage tank at the bottom of the filter at the same time, in the end through the outfalls. Control system:

since start cleaning device is controlled by differential pressure sensor, when the pressure difference at the rated value, self-cleaning device will automatically start, also can set time to initiate the cleaning device on a regular basis.

automatic online cleaning filter ( SQ type) The range of the material is as follows:
. Weak corrosively medium for chemical industry, petroleum chemical industry production, such as: water, ammonia, oil, hydrocarbon, etc.
. Chemical production of corrosive materials, such as: caustic soda, thick dilute sulphuric acid, carbonic acid, acetic acid, acid, etc.
. Refrigeration in the low temperature materials, such as: liquid methane, ammonia, oxygen, and a variety of cooling agent.
. In the production of food, pharmaceutical materials with health requirements, such as beer, beverage, dairy products, syrup medical supplies, etc.
