Composed of nuts. During compression, the motor rotates forward, driving the reducer and gear set, causing the screw rod to rotate in the fixed nut, pushing the compression plate, and compressing the
Filter Plate and filter frame. As the pressing force becomes larger and larger, the load current of the motor increases. When the current value set by the protector is reached and the maximum pressing force is reached, the motor cuts off the power supply and stops rotating. Since the screw rod and the fixed nut have a reliable self-locking helix angle, they can reliably ensure the compression state during the working process. When retracting, the motor reverses. When the pressure block on the pressure plate hits the travel switch, the retraction stops.
The entire filter chamber of the
Filter Press is tight. The hydraulic test is carried out at a filtration pressure of 1.25 times and maintained at this pressure for 5 minutes. Leakage due to the capillary action of the filter material is allowed to exist on the pressing surface. Others There is no leakage from the seal.
Without any padding, the gap between the filter plate and filter frame of the filter press shall not be greater than 0.35mm after being compressed by the rated compression force.
The control system, pressing device, filter plate moving device,
Filter Cloth cleaning device, unloading device, etc. should be flexible and reliable.
After the plate and frame filter press is overhauled, the mean time between failures should be greater than 4500h.
