The special equipment for stainless steel filter press occasionally fails to press up and lacks pressure during use. After this situation, the material in the filter chamber of the stainless steel filter press will be insufficiently filtered and the moisture content will be high, which will affect the pressing efficiency. Speed ​​and increase the pressing time. When this problem occurs, the cause and treatment method should be found in time to avoid affecting production efficiency.

The reasons for the lack of pressure of the special equipment for stainless steel filter press and the inability to hit the pressure should be found from the following aspects:

First, the operation of the stainless steel filter press should be checked first. Since the filter press is a complete system, the interior is a closed environment during operation, and the pressure relief of a certain link will cause a lack of system pressure. The inspection items mainly include filter Whether there is a hole in the cloth, whether the hydraulic system leaks oil, and whether the seal is leaking.

2. Secondly, inspect the pipelines and gate valves, including the gate valve of the feed pipeline of the stainless steel filter press and the feed and discharge gate valves of the stainless steel filter press equipment. First, check whether the pipeline is damaged, whether the gate valve is fully opened, and whether there is any leak.

3. Inspect the operation of the special equipment for stainless steel (stainless acid-resistant steel) filter presses, and check whether there is any blockage. Blockage will lead to lack of flow and slow flow rate, which will affect the pressure and feeding. The stainless steel filter press is manually pressed and the motor is pressed. , active hydraulic pressing, active pressure maintaining, electrical control\/computer program control, active pulling plate, active liquid-contacting flap, etc. In addition, for new equipment, it should be checked that the speed is too low and the motor power is too small , These two items will cause this phenomenon; for equipment with problems in normal use, the power speed is generally no problem, it is necessary to check whether the impeller is severely worn, and check whether the seal of the equipment is leaking.

4. After finding the problem, it should be dealt with in time. If the pressure is insufficient and the pressure cannot be applied again, it should be further investigated to see if there are multiple leak points or multiple reasons for this situation. The low-temperature dryer uses a special A filter medium that exerts a certain pressure on the target to make the liquid dialyze out is a kind of commonly used solid-liquid separation equipment.
