Filter presses play a vital role in global industrial production and environmental protection. In order to ensure the long-term stable operation of the filter press and extend its service life, routine maintenance and regular maintenance are crucial. This article will introduce in detail the routine maintenance and regular maintenance methods of filter presses, as well as common troubleshooting methods and repair recommendations.
- Daily maintenance methods
- Parts inspection
-Before starting the machine every day, check whether the parts of the filter press are intact, including the filter plate, filter cloth, hydraulic system, electrical system, etc. Check whether the filter plate is deformed, cracked or not. Check whether the filter plate is deformed, cracked or damaged, and whether the filter cloth is broken or clogged.
-Check whether the oil level of the hydraulic system is normal and whether there is leakage in the hydraulic pipeline. At the same time, check whether the wiring of the electrical system is loose and whether the electrical components are working normally.
2.Cleaning and maintenance
-After each use, clean the filter plate and cloth of the filter press in time. Rinse the residual material on the surface of the filter plate with water and clean the impurities on the filter cloth with a soft brush. Avoid using sharp tools to scrape the filter plate and cloth to avoid damaging them.
-Clean the filter of the hydraulic system regularly to prevent impurities from entering the hydraulic system and affecting the normal operation of the equipment. At the same time, clean the control cabinet and electrical components of the electrical system to keep them clean and dry.
3.Lubrication maintenance
-Regularly lubricate and maintain the various moving parts of the filter press, such as chain, sprocket, bearing, etc.. Use suitable lubricating oil or grease, and carry out lubrication operation according to the requirements of the equipment manual.
-Pay attention to the time and frequency of lubrication to avoid over-lubrication or under-lubrication. Excessive lubrication may lead to grease leakage and pollute the environment; insufficient lubrication will accelerate the wear and tear of the parts and affect the service life of the equipment.
Second, regular maintenance methods
- Replacement of filter plate and cloth
-Replace the filter plate and cloth regularly according to the use of the filter press and the wear and tear of the filter plate and cloth. Generally speaking, the service life of filter plate is 1-2 years, and the service life of filter cloth is 3-6 months.
-When replacing the filter plate and cloth, choose reliable quality products and strictly follow the requirements of the equipment manual for installation and commissioning. Ensure that the filter plate and cloth are installed correctly and sealed well to avoid leakage.
- Maintenance of hydraulic system
-Check whether the working pressure of the hydraulic system is normal on a regular basis, and adjust it in time if there is any abnormality. At the same time, check the quality of hydraulic oil and oil level, if you find that the hydraulic oil is deteriorated or the oil level is too low, you should replace or add hydraulic oil in time.
-Clean the oil tank and oil pipe of the hydraulic system regularly to remove the impurities and dirt in it. At the same time, check whether the seals of the hydraulic system are intact, if damaged, should be replaced in time.
- Maintenance of electrical system
-Regularly check whether the grounding of the electrical system is good, whether the wires are broken, aging and other problems. If there is any problem, the wires should be repaired or replaced in time.
-Check whether the controller and sensor of the electrical system are working properly, if there is any fault, it should be repaired or replaced in time. Also, clean and maintain the electrical system regularly to keep it dry and clean.
Third, common troubleshooting methods and maintenance recommendations
- Filter plate leakage
-Failure causes: impurities on the sealing surface of the filter plate, deformation of the filter plate, damage to the seals.
-Troubleshooting methods: clean the sealing surface of the filter plate to remove impurities; check whether the filter plate is deformed, and replace it in time if it is deformed; check whether the seals are damaged, and replace them in time if they are damaged.
-Maintenance suggestions: When installing the filter plate, make sure that the sealing surface is clean and flat and the seals are installed correctly. At the same time, regularly check the condition of the filter plate and seals, and replace the damaged parts in time.
- Hydraulic system failure
-Failure causes: insufficient hydraulic oil, hydraulic oil contamination, hydraulic pump failure, hydraulic cylinder leakage.
-Troubleshooting methods: check the oil level of hydraulic oil, such as insufficient should be added in a timely manner; replacement of contaminated hydraulic oil; check the working status of the hydraulic pump and hydraulic cylinder, if any failure should be repaired or replaced in a timely manner.
-Maintenance recommendations: regularly check the working condition of the hydraulic system, timely replacement of hydraulic oil and seals. At the same time, pay attention to the maintenance of the hydraulic system to avoid damage to the equipment due to improper operation.
- Electrical system failure
Failure causes: short-circuit wires, electrical components are damaged, controller failure.
Troubleshooting methods: check whether the wire is short-circuited, if short-circuited should be repaired in a timely manner; check whether the electrical components are damaged, if damaged should be replaced in a timely manner; check whether the controller is working properly, if there is a malfunction should be repaired or replaced in a timely manner.
-Maintenance suggestions: Check the working status of the electrical system regularly and replace damaged electrical components and wires in time. At the same time, pay attention to the safety protection of the electrical system to avoid safety accidents caused by electrical failure.
In conclusion, routine maintenance and regular maintenance of filter press is the key to ensure the long-term stable operation of the equipment. Through correct maintenance and maintenance methods, the service life of the filter press can be extended, the working efficiency of the equipment can be improved, and greater economic benefits can be brought to users. At the same time, when encountering failures, users should take effective troubleshooting methods and maintenance recommendations in a timely manner to ensure that the equipment can resume normal operation as soon as possible.
