As an important filtration equipment, diaphragm filter press is widely used in various industries. However, during use, sometimes the filter chamber is not sealed, which not only affects the filtration effect, but also leads to the degradation of equipment performance. This article will analyze the three main reasons why the filter chamber of the diaphragm filter press is not sealed, and take the corresponding solutions.
First, the quality of the filter cloth is not up to standard.
The filter cloth is an important part of the filter chamber of the filter press, and its quality directly affects the filtration effect. If there is a quality problem with the filter cloth, such as uneven thickness, too large or too small holes, etc., it will lead to a decrease in the fit between the filter cloth and the diaphragm plate, which in turn will cause the filter chamber to be unsealed. To avoid this, filter cloths of acceptable quality should be selected and carefully inspected before use to ensure that they meet the process requirements.
2. Improper installation of the diaphragm plate.
The diaphragm plate is one of the main components of the diaphragm filter press, and the quality of its installation has a crucial impact on the tightness of the filter chamber. If the diaphragm plate is not properly or securely installed, it will cause the fit between the filter cloth and the diaphragm plate to be reduced, which in turn will cause the filter chamber to be unsealed. To solve this problem, ensure that the diaphragm plate is installed correctly and securely, and that the operating procedures are strictly followed during installation.
3. Hydraulic system failure.
The hydraulic system is one of the important components of the diaphragm filter press, and its normal operation has an important impact on the tightness of the filter chamber. If the hydraulic system fails, such as oil leakage from the oil cylinder, poor oil circuit, etc., it will lead to insufficient or uneven pressure, which in turn will cause the filter chamber to be unsealed. To solve this problem, the operation of the hydraulic system should be checked regularly to ensure that it is working properly. Once a fault is found, it should be repaired or replaced in time.
To sum up, the reasons for the unsealing of the filter chamber of the diaphragm filter press mainly include poor quality of filter cloth, improper installation of diaphragm plate and failure of hydraulic system. In order to solve this problem, we should start from these three aspects, strengthen equipment maintenance and maintenance, improve the skill level of operators, and ensure the normal operation of equipment. At the same time, attention should also be paid to the optimization of equipment selection and design stage to improve the reliability and stability of equipment, so as to reduce the occurrence of problems such as unsealed filter chambers. Only in this way can we give full play to the advantages of the diaphragm filter press and improve the production efficiency and product quality.
