The problem that the plate and frame filter press cannot be loosened during use may be caused by a variety of factors. First of all, we need to understand the basic working principle and structure of the plate and frame filter press in order to better analyze the cause of the problem. Plate and frame filter press is a kind of equipment that realizes solid-liquid separation through plate and frame extrusion, which is mainly composed of filter plate, filter frame, pressing device, hydraulic system and other parts. When the filter press cannot be loosened, it can usually be troubled from the following aspects:
First, the hydraulic system problem.
The pressing operation of the plate-and-frame filter press is achieved by means of a hydraulic system. If the hydraulic system fails, it can cause the filter press to not press properly. For example, a damaged oil pump, a blocked oil circuit, a faulty solenoid valve, etc., can cause the hydraulic system to not work properly. At this point, it is necessary to inspect the various components of the hydraulic system, find the fault point and repair it.
Second, the problem of filter plate and filter frame.
The filter plate and filter frame are the core components of the plate and frame filter press, and their condition directly affects the compression effect of the filter press. If the filter plate and filter frame are deformed, worn, aging and other problems, it may cause the filter press to fail to close tightly. At this time, the filter plates and filter frames need to be inspected and replaced to ensure their flatness and tightness.
3. Insufficient compaction force.
Insufficient compaction is also one of the common reasons why the plate and frame filter press cannot be loosened. The magnitude of the hold-down force depends on the pressure of the hydraulic system and the transmission ratio of the hold-down mechanism. If the hydraulic system pressure is insufficient or the gear ratio is not matched, it may result in insufficient compression force. At this point, it is necessary to adjust the pressure of the hydraulic system or change the transmission ratio to improve the pressing force.
Fourth, improper operation.
When operating the plate and frame filter press, if it is not operated properly, it may also cause the filter press to not loosen. For example, the pressing process is not carried out according to the prescribed procedures, and the compression is carried out without waiting for the hydraulic system to stabilize. Therefore, when operating the plate and frame filter press, it is necessary to strictly follow the operating procedures to ensure the correctness and safety of the operation.
In view of the above several possible reasons, we can take corresponding measures to solve the problem that the plate and frame filter press cannot be loosened. First of all, a comprehensive inspection of the hydraulic system is required to identify and fix the point of failure. Secondly, the filter plate and filter frame are inspected and replaced to ensure their flatness and tightness. At the same time, adjust the pressure and transmission ratio of the hydraulic system to improve the pressing force. Finally, when operating the plate and frame filter press, it is necessary to strictly follow the operating procedures to ensure the correctness and safety of the operation.
In addition to the above aspects of troubleshooting and repair measures, we can also take some precautions to avoid the problem of plate and frame filter press not loosening. First of all, the plate and frame filter press is regularly maintained and maintained to ensure the normal operation and good condition of each component. Secondly, in the process of use, it is necessary to pay attention to observe the operating status of the filter press, and find and deal with abnormal situations in time. Finally, strengthen the training and management of operators, improve their operation skills and safety awareness, and ensure the normal operation and safe production of the filter press.
In short, the problem of the plate and frame filter press not being loose may be caused by a variety of factors, and we need to investigate and repair it from multiple aspects. At the same time, taking preventive measures can avoid the recurrence of similar problems and ensure the normal operation and safe production of the plate and frame filter press.
