3. Check the working condition of the special equipment of stainless steel (stainless acid-resistant steel) filter press (check if there is any blockage, the blockage will cause insufficient flow rate and slow flow rate, which will affect the pressure and feed. Tightening, automatic hydraulic pressing, automatic holding pressure, electrical control / computer program control, automatic pulling plate, automatic liquid-receiving flap, etc. In addition, for newly installed equipment, you should check whether the speed is too low and the motor power is too small Both of these will cause this phenomenon; for equipment that has problems in normal use, the power and speed are generally okay, you need to check whether the impeller is seriously worn, and check the equipment for leaks.
4. After finding the problem, it should be solved in time. If the situation of insufficient pressure can not hit the pressure again, it should be further investigated whether there are multiple leakage points or multiple causes of this situation. The low-temperature dryer uses a special filter medium to apply a certain pressure to the object, which makes the liquid dialysis out of a mechanical device, which is a commonly used solid-liquid separation device. Material of stainless steel filter press filter plate: stainless steel, cast iron, rubber, reinforced polypropylene (plastic), polymer PE, etc.
