Occasionally, the special pump for the filter press will not be able to pump up the pressure and the pressure will be insufficient. This situation will cause insufficient filtration of the material in the filter chamber of the filter press, high water content, and will affect the pressing speed. Increase pressing time.

When such a problem occurs, the cause and solution should be found out in time to avoid affecting production efficiency. So how to find out the cause of the problem and how to solve it is what we are going to discuss today. Without further ado, let's take a look.

If the pressure of the special pump for the filter press is insufficient and cannot be pumped up, the reasons should be found from the following aspects:

1. Check the pipelines and gate valves, including the feed pipeline gate valve of the filter press and the feed and discharge gate valves of the filter press pump, mainly to check whether the pipeline is damaged, whether the gate valve is fully opened, and whether there is any leakage.

2. After the problem is found, it should be solved in time. If the pressure is insufficient and the pressure cannot be increased again, it should be further checked to see if there are multiple leakage points or various reasons for this situation.

3. The working conditions of the filter press should be checked. Since the filter press equipment is a complete system, the interior is a closed environment during operation, and pressure relief at a certain link will cause insufficient system pressure. The inspection items mainly include whether there are holes in the filter cloth, whether there is oil leakage in the hydraulic system, and whether there is material leakage in the seal.

4. Check the working condition of the special pump for the filter press to see if there is blockage. Blockage will lead to insufficient flow and slow flow rate, which will affect the pressure and material supply. In addition, for newly installed pumps, it should be checked whether the speed is too low and the power of the motor is too small. Serious, check the pump seals for leaks.

The above four points are the reasons why the special pump for the filter press may have insufficient pressure. Of course, these four points are for reference only, and specific faults should be found in combination with the actual situation.
