What is the maintenance and maintenance of the automatic vertical diaphragm filter press?
1. In the automotive industry, filtration products have been widely used, such as water for painting and some coatings and paints.
2. In the electronics industry, water needs to be treated before the process starts. Here, filter products can be used.
3. In the edible oil and beverage industries, a series of treatments are also required before juice is made, or the beverages are filtered and clarified.
4. In the petrochemical and pharmaceutical industry, when chemicals need to remove particles and other substances, filter products are used.
5. In the biopharmaceutical industry, filtration products are needed for some washing water filtration.
6. In environmental protection, some industrial and domestic water needs to be filtered.
Troubleshooting and maintenance of the automatic vertical diaphragm filter press. After the user has used the filter press for some time, maintenance and maintenance must be on the schedule. How to properly maintain and troubleshoot the filter press becomes very critical , Here are some methods I summarized for your reference: Maintenance of the filter press during use is very important. It is necessary to lubricate and maintain the matching parts and transmission parts, especially the feedback signal position of the automatic control system (electric contact The accuracy and reliability of the action of the pressure gauge and the travel switch, etc.) and the hydraulic components of the hydraulic system must be ensured so as to maintain normal operation. For this reason, the following points should be done:
1. At any time, carefully check whether the connections are firm and whether the parts are in good condition. If abnormal conditions are found, the maintenance personnel should be notified for maintenance.
2. Regular inspections should be carried out on the pull plate trolley, sprocket chain, bearing, piston rod and other parts to keep all the matching parts clean and good lubrication performance. The hydraulic filter press has a good operating manual to ensure flexible movement. The synchronization and the drape of the chain should be adjusted in time.
3. Conduct regular insulation and reliability tests on the electronic control system, and find that the actions caused by electrical components have poor accuracy and inflexibility, and should be repaired or replaced in time.
4. The maintenance of the hydraulic system is mainly the inspection and maintenance of the hydraulic components and the sealing of each interface.
5. Check the sealing surface of the filter plate frequently to ensure it is smooth and clean; before pressing, carefully check the filter cloth to ensure that it is free of folds, damage, and slag, and it is flat and intact to ensure filtration Effect: At the same time, the filter cloth should be washed frequently to ensure the filter performance of the filter cloth.
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 compressed with a pressure of 1 to 5 MPa. The filter cloth is cleaned and dried; the exposed part of the piston rod and the integrated block should be coated with butter.
7. Use HM46 or HM68 hydraulic oil, and it must be kept clean. The hydraulic oil should be changed once a week when the new machine runs for the first time. When changing the oil, drain the used hydraulic oil in the oil tank and the oil cylinder and clean the oil tank. If you continue to use it, replace it once a month, and then replace it every six months to ensure the normal use of the filter press. When we have problems with the troubleshooting and maintenance of the filter press of the coal washing machine equipment, it is enough to repair or repair the filter press according to the above aspects, or the filter cloth cannot be used.
7.1. The influent sludge contains hard solids, which will cause serious holes after being squeezed by the filter cloth.
7.2. The abnormal operation caused serious creases and unevenness of the Yuanzhen filter cloth.
7.3. The joint insert strip often breaks, causing serious damage to the joint.
7.4. Serious wire stripping occurs at the edges of both sides of the filter cloth.
7.5. Those who cannot be cleaned for a long time, and there is still no improvement after removing the acid and washing
