If the diaphragm filter press makes abnormal noise during use, it is mainly caused by aging of the motor or motor overload, or damage to the pressure oil pump.
Generally speaking, it is the working type of plunger pump. If the hydraulic oil is abnormal or used for a long time, it will cause continuous damage, and abnormalities will occur at this time. In addition, when installing the hydraulic station, if it is a coupling, it is not a concentric shaft. Also, when its installation position is not accurate enough, the motor will be too large, and its liability will gradually increase at this time.
The above are some reasons that cause the filter press to make abnormal sounds during use. Only by finding out the corresponding causes can we find their corresponding solutions, and each one can be fully solved.
Therefore, once this happens to the machine, the equipment must be suspended and the problem solved in time.
The unbalanced pressure on both sides of the filter plate of the diaphragm filter press will cause deformation and damage to the middle part of the filter plate.
When the machine is working, the filter plate needs to withstand a force of 0.6MPa. The pressure of the slime water causes the water to be filtered out through the filter cloth, and the solid particles pass through to form a slime cake. When working normally, the pressure on both sides of the filter plate is balanced, and the pressure gradually rises from small to large to the outlet pressure of the feed pump. When the operation is abnormal (because the water outlet is blocked), the pressure in the filter chamber will quickly rise to the outlet pressure of the feed pump, while the water outlet on the other side of the filter plate is normal or the feed is not smooth. The pressure in the filter chamber will gradually rise. , so that a gap is formed on both sides of the filter plate, causing deformation of the middle part of the corrugated plate, thereby damaging the filter plate.
Therefore, during the feeding period of the filter, you must directly observe the water outlet situation. If there is no water coming out of the water outlet, it means that the water outlet may be blocked. Stop the feed pump immediately, pull the tight plate and the water outlet blocked or the water outlet may be clogged. If the filter plate has poor feeding, check and repair it, and resume feeding and filtering after the fault is eliminated.
