What problems should be paid attention to when operating a box filter press?

After the box filter press is turned on, carefully observe the working conditions of the machine. If there is any abnormality, it should be stopped immediately for maintenance. The oil temperature in the fuel tank should not be higher than 60 degrees Celsius; water and dust are strictly prohibited in the fuel tank; the oil filter on the hydraulic station It should be cleaned frequently. The electrical control part should be tested for insulation performance once a month, and the damaged electrical components should be replaced or repaired in time.

The filter cloth used in the box filter press should not be damaged, and the sealing surface should not be wrinkled or overlapped. Always check the parts of the whole machine, whether the installation of components is safe, whether the hydraulic system leaks oil, and whether the transmission parts are flexible and reliable. Check the hydraulic pressure frequently. Oil quality, whether the oil level meets the requirements, and whether the oil is pure.

When the box filter press is used, the filtration pressure, pressing pressure and material temperature are not allowed to exceed the specified values. When the plate frame is missing or the displacement of the pressing plate is greater than the piston stroke, it is strictly forbidden to start the machine. When the oil pump is started in winter, the hydraulic oil should be added as needed. It can be put into use only when the oil temperature rises to above 15 degrees Celsius.

When the edge of the box filter press is damaged, even if it is slightly raised, no matter what the pressure, the formed filter chamber will permeate. We judge this according to the situation of the leakage point. will be relatively large, and may even be sprayed.

Since the structure of the filter chamber is formed by the mutual cutting of the filter plate and the filter cloth, which is subjected to strong pressure, the general filter plate is not prone to problems, and the rest is the filter cloth. To form a seal between the hard filter plates, The filter cloth plays a key role, and the wrinkles or incompleteness of the natural filter cloth can easily cause gaps between the filter plates, and the natural filter chamber will not form a seal.

Insufficient pressure The filter plate and filter cloth must be under strong pressure to achieve a closed filter chamber structure. When the pressure is insufficient, when the pressure applied to the filter plate is less than the pressure of the filtrate, the natural filtrate will also be taken for granted. can penetrate through the gaps.
