Coolant central filtering system is mainly used in machine processing line for central cooling and filtrating. It is composed of scraper chip conveyor, negative pressure paper band filter, coolant distributor, liquid-supply pump group, coolant anti-corrosion system, PLC electric control system and coolant-return pump etc.
The liquid supply and return are divided into three schemes: one is all pipelines are overhead: second is overhead supply, liquid return intrench; Third is both liquid-supply pipeline and return return pipeline are intrench .The schemes are different because of the difference of workshop conditions and chips .We can design as users’ requirements. This device can be used with oil separator, purification regeneration system and automatic proportion liquid adding device. It supplies a better method for the effectiveness of coolant and the cleanness of workshop .The system is not only cost-saving but also creates an excellent working environment.
The coolant central filtering system uses negative pressure paper band filtering method. It can energy-efficient supply liquid underfrequency ,constant pressure condition.
This system is high precision, large flow rate and can supply liquid for 24hours, Frequency-conversion pump can supply liquid by constant voltage. It runs automatically, has analogue display, failure display and alarm. The device runs stable and has few faults.
