Precautions and maintenance for operation of plate and frame filter press

1、 Preparation before operation: 1 Whether the number of boards and frames meets the requirements It is forbidden to start the machine when the number of boards and frames is less than the specified number 2 Check whether the filter cloth is damaged The filter cloth hole is smaller than the plate frame hole and concentric with the plate frame hole 3 Whether the arrangement order of plates and frames meets the requirements, whether the installation is smooth, and whether the sealing surface contacts well 4 Whether the hydraulic system works normally and whether the pressure gauge is sensitive and easy to use 5 Check whether all pipelines of filter press are smooth and whether there are leakage points 2、 Precautions during operation: 1 When the plate frame moves on the main beam, it is not allowed to collide or hit, and the force should be balanced to prevent the handle from being damaged and the sealing surface from being damaged 2 The valves of materials, compression, washing liquid or hot water must be started according to the operation procedure, and shall not be started at the same time 3 When cleaning the plate frame and filter cloth after cake unloading, make sure that the channel is unblocked, and no residue is allowed to be pasted on the sealing surface or in the feeding channel 4 When the hydraulic system stops operating, the long lever hand wheel of the operating device shall be normally open and the short lever hand wheel shall be normally closed to ensure safety and avoid oil waste 5 The filter press cloth must be installed flat without folding, so as to prevent damage to the plate frame and leakage during pressing 6 The working pressure of the rubber plastic plate frame Zui of the hydraulic station shall not exceed 20MPa 7 The filtering pressure must be less than 0.45MPa, and the temperature of the filtering material must be less than 80 ℃, so as to prevent leakage, plate frame deformation, tearing, etc 8 The overflow valve of the control device must be adjusted to the Zui small working pressure that can make the piston return 3、 Daily maintenance: 1 Pay attention to whether the connecting parts of each part are loose, and fasten them at any time 2 Check whether the working pressure of the hydraulic system and the oil volume in the oil tank are within the specified range every shift 3 Clean 46 × hydraulic oil shall be added into the oil tank and filtered through 80-100 mesh filter screen It is forbidden to add oil containing impurities or moisture into the oil tank 4 The operator shall clean the equipment at any time, keep the filter press clean and tidy, and make the equipment body and its surroundings free of filter cake, sundries, etc 5 The pressing shaft or screw shall be well lubricated to prevent foreign matters 6 The pressure gauge shall be calibrated regularly to ensure its sensitivity 7 The removed plates and frames shall be stacked flat during storage to prevent deflection and deformation Our company is a professional manufacturer which produces and sells a series of plate and frame filter press, bean paste filling dehydrator, steel lined ion exchange column, starch sugar complete set of equipment.
