The unbalanced pressure on both sides of the filter plate of the diaphragm filter press is a common problem in the use of the filter press, which will lead to the distortion and deformation of the filter plate, which will affect the filtration effect and service life. To solve this problem, the following measures can be taken:
1.Check the hydraulics.
The hydraulic system of the diaphragm filter press is a key factor affecting the pressure equalization. First of all, check whether the oil circuit of the hydraulic system is smooth, whether the oil pump is working normally, and whether the oil cylinder has oil leakage and oil leakage. If an abnormality is found, the oil circuit should be cleaned or the oil pump and seals should be replaced in time.
2.Adjust the plate spacing.
Uneven spacing of filter plates can also lead to uneven pressure. When adjusting the spacing of filter plates, the flatness and spacing of adjacent filter plates should be ensured to be consistent to avoid the phenomenon of excessive local pressure. At the same time, it is necessary to ensure that the material and thickness of the filter plate meet the requirements to prevent pressure imbalance caused by uneven material or uneven thickness.
3.Adjust the diaphragm position.
The position of the diaphragm in the diaphragm filter press can also affect the pressure equalization. When adjusting the position of the diaphragm, it should be ensured that the fit between the diaphragm and the filter plate is good, and there is no gap or misalignment. At the same time, it is necessary to ensure that the material and thickness of the diaphragm meet the requirements to prevent pressure imbalance caused by uneven material or uneven thickness.
4.Adjust the pressure of the filter press.
Filtration pressure is an important factor affecting the filtration effect and pressure balance of the diaphragm filter press. When adjusting the pressure of the filter press, the pressure distribution should be ensured to be evenly distributed to avoid the phenomenon that the local pressure is too high or too low. At the same time, the filter pressure should be adjusted according to the actual situation to achieve the best filtration effect and equipment life.
5.Regular maintenance.
Regular maintenance is an important measure to keep the diaphragm filter press running normally. In daily use, the wear and aging of key components such as filter plates, diaphragms, and hydraulic systems should be checked regularly, and the wear parts should be replaced and the oil circuit should be cleaned in time. At the same time, it is necessary to carry out a comprehensive inspection and maintenance of the equipment on a regular basis to ensure the normal operation and service life of the equipment.
To sum up, to solve the problem of uneven pressure on both sides of the filter plate of the diaphragm filter press, it is necessary to start from many aspects, including checking the hydraulic system, adjusting the spacing of the filter plates, adjusting the position of the diaphragm, adjusting the filter pressure and regular maintenance. In actual operation, corresponding measures should be taken according to the specific situation to ensure the normal operation and service life of the equipment. At the same time, the operator should have the corresponding skills and knowledge to be able to use and maintain the diaphragm filter press correctly to avoid equipment failure or safety accidents caused by improper operation.
