1. Maintenance - The maintenance of the filter press during the use is very important. It is necessary to lubricate and maintain the mating part and the transmission part, especially the feedback signal position of the automatic control system (electric contact pressure gauge and stroke switch, etc.) and hydraulic system. The accuracy and reliability of the operation of the hydraulic components must be guaranteed in order to maintain normal operation. The following should be done:
1.1 Check whether the joints are firm at all times, whether the parts are used well, and notify the maintenance personnel to check the abnormal conditions.
1.2 The pull plate trolley, sprocket chain, bearing, piston rod and other parts should be inspected regularly to keep the matching parts clean, and the lubrication performance is good. The hydraulic filter press instruction manual is good to ensure flexible movement. Synchronization and the drape of the chain should be adjusted in time.
1.3 The electrical control system should be tested regularly for insulation and reliability. It is found that the accuracy and inflexibility caused by the electrical components are inaccurate and should be repaired or replaced in time.
1.4 Maintenance of the hydraulic system, mainly for the inspection and maintenance of the sealing of hydraulic components and interfaces.
1.5 Always check the sealing surface of the filter plate to ensure it is clean and clean; before pressing, the filter cloth should be carefully inspected to ensure that it is not folded, damaged, or slag-free, so that it is well-formed to ensure the filtration effect. At the same time, always wash the filter cloth to ensure the filtration performance of the filter cloth.
1.6 If it is not used for a long time, the filter plate should be cleaned and discharged neatly on the frame of the filter press, and pressed with a pressure of 1 to 5 MPa. The filter cloth is dried after drying; the exposed part of the piston rod and the integrated block should be buttered.
1.7 Hydraulic oil uses HM46 or HM68 and must be kept clean. The new machine should be replaced with hydraulic oil once a week. When changing oil, the hydraulic oil used in the fuel tank and cylinder should be drained and the tank cleaned. Continue to use it once a month and replace it once in the next six months. This will ensure the normal use of the filter press.
When we have problems with the van filter press, it is enough to repair or cultivate according to the above aspects.
Filter press troubleshooting and maintenance
When the user uses the filter press for some time, maintenance and maintenance should be mentioned on the schedule. How to properly maintain and troubleshoot the filter press becomes very important. Here are some methods I have summarized for your reference:
