Is the daily maintenance of filter press really necessary?

Sometimes, due to long working hours, high ambient temperature, high pressure and other reasons,Filter PressThere will be transitional work phenomenon. Sand washing filter mechanismFilter plate, Filter frame,Filter clothSqueezing membrane, both sides of the filter plate are covered by filter cloth, when squeezing membrane needs to be configured, a group of filter plates are composed of membrane plate and side plate. The two sides of the base plate of the diaphragm plate are covered with rubber membrane, and the outer side of the membrane is covered with filter cloth, and the side plate is the ordinary filter plate. When there is transition work, we need to do some work to slow down the solution and make the filter press run more effectively. Therefore, how to judge the transition work of filter press is very necessary. Next, let's talk about some performance of the filter press transition. The poor quality of filter cake after filtration is the main manifestation of the work transition of filter press equipment. Once the filter chamber is not perfect, the solid-liquid separation will be unwillingly realized, and the final filter cake may not achieve the expected effect in moisture content and formation, or the moisture content of the filter cake may become higher, or the filter cake cannot fill the gap of the filter chamber, etc. The transition work of filter press is first reflected in the power system. The power system of the filter press not only provides power for the operation of each part of the equipment, but also provides strong pressure for the filter plate, making the filter plate become a closed filtering environment. When the filter press equipment works for a long time, the hydraulic oil of the hydraulic system may be overheated, making the hydraulic oil no longer able to bear relatively strong pressure, and its volume will change with the change of pressure. This directly results in that the hydraulic system cannot generate enough power.

In the working process, when the power system of the equipment can not generate pressure normally, the pressure acting on the filter plate will naturally decrease, and the pressure acting on the filter plate will also decrease accordingly. Then the natural filter chamber made of filter plate can not resist the impact of filter liquid, and the natural filter chamber will have leakage phenomenon. Once the filter liquid leaks, it will directly reduce the filtering efficiency of the filter press. This is the second sign of overload of filter press equipment.

In the process of operation, if the transitional work of the filter press will also lead to the abnormality of working efficiency and quality, it is necessary to judge whether it is transitional work when problems occur to the efficiency and quality of the filter press, so as to solve it better. Diaphragm filter press is a filter press with a layer of elastic membrane between the filter plate and the filter cloth. In the process of using, when the feeding is finished, high pressure fluid or gas medium can be injected into the diaphragm plate, then the whole diaphragm will bulge and press the filter cake, thus realizing further dehydration of the filter cake, it is usually called squeezing and filtering.

In a word, the daily maintenance of the filter press is very necessary. More maintenance can prolong the service life of the machine and make the machine put into production more smoothly in the working process. Enterprises using filter press must remember to carry out various maintenance on the filter press regularly.
