BCM-Automatich Backwash Filter

Description

BCM automatic backwash filtration system is an electromechanical integration product, designed for continuous maintenance-free filtration for all major manufacturing and processing industries. It removes solid contamination from lost viscosity fluids such as water and machine tool coolants. Its rugged construction and automatic backwash feature provide companies with increased machinery reliability resulting in continuous flow during backwash, reduced operating, labor and maintenance costs. The process begins with fluid passing through the inlet flange reaching the filter elements by flowing from inside the element to outside. Solid contamination is then trapped on the inside of the filter element. As contamination increases, the differential pressure between the contaminated and clean side increases. When the set differential pressure is reached, automatic backwash is triggered. The backwash process is one complete cycle which cleans one element at a time in succession. The geared motor turns the contamination discharge arm under the filter element to be cleaned. The contamination discharge valve is then opened by a pneumatic actuator. This results in a high pressure drop with the filter element being cleaned, which forces the particles into the discharge line. During this operation, only a small amount of clean fluid is used to complete the cleaning process. The design of BCM automatic backwash filter is simple yet highly effective. The basic construction consists of the motor, main housing, inlet and outlet ports with flanged connections, filter elements, outlet valve and actuator and HMI control system. When the set backwash time is reached, the contamination discharge valve is closed, and the backwash finishes. Then the geared motor turns the contamination discharge arm again, and another backwash starts. After all the filter elements are cleaned, the contamination discharge arm is turned back by the contrinex, then the operation cycle finishes.
