The filter plate of the plate and frame oil purifier may encounter various problems during use, such as loosening, deformation, cracking, water seepage, etc. These problems need to be repaired in time to ensure the normal operation of the equipment. The following are some common methods for repairing filter plates:
1. Check the power system: The pressure system of the plate and frame filter press provides power pressure for the filter plate to make the filter plate close and seal. If the power system does not provide pressure to the filter plate, the filter plate will loosen. Check whether the hydraulic system is leaking oil, whether the O-ring is worn, whether the solenoid valve is working properly, and whether there is air in the cylinder.
2. ｒｅｐｌａｃｅ the O-ring: If the O-ring is worn, it will cause oil leakage in the hydraulic system, which will affect the compression of the filter plate. A new O-ring needs to be replaced.
3. Clean the solenoid valve: Blockage of the solenoid valve will also affect the normal operation of the hydraulic system. The solenoid valve should be cleaned regularly to ensure that it is unobstructed.
4. Remove air from the cylinder: If air is mixed into the hydraulic cylinder, it will affect the stability of the hydraulic system. The air in the cylinder needs to be removed to ensure the normal operation of the hydraulic system.
1. ｒｅｐｌａｃｅ the filter plate: If the filter plate is severely deformed or cracked and cannot be repaired, a new filter plate needs to be replaced.
2. Evenly distribute the material: During the filter pressing process, ensure that the material is evenly distributed each time to avoid deformation or cracking of the filter plate due to excessive local pressure.
3. Check the clamping system: Ensure that the clamping system works properly and the pressure is evenly distributed to avoid deformation of the filter plate due to insufficient or uneven clamping force.
1. Increase the clamping pressure: If water seepage occurs between the filter plates, the clamping pressure should be increased first to ensure that the filter plates fit tightly.
2. ｒｅｐｌａｃｅ the filter cloth: Damage or wrinkles in the filter cloth can also cause water seepage. The condition of the filter cloth should be checked regularly, and it should be replaced in time if it is damaged, and ensure that the filter cloth is installed flat and wrinkle-free.
3. Clean the sealing surface: Debris attached to the sealing surface of the filter plate can also cause water seepage. The sealing surface should be cleaned regularly to ensure that there are no impurities and damage.
4. ｒｅｐｌａｃｅ the seal: If the sealing ring is aged or damaged, it will also cause water seepage. New seals should be replaced in time.
1. Clean the guide rod regularly: Too much oil and dirt on the guide rod will increase friction and affect the movement speed of the filter plate. The guide rod should be cleaned regularly and lubricated with butter.
2. Check the oil circuit: Check the oil circuit regularly for squeezes or blockages to ensure that the oil circuit is unobstructed.
3. Adjust the feed pressure: Avoid excessive feed pressure that causes the filter plate to rupture or deform. The feed pressure should be adjusted appropriately according to the material characteristics and equipment requirements.
4. ｒｅｐｌａｃｅ electrical components: If the electrical components are damaged, the control system will fail. The status of electrical components should be checked regularly and replaced in time if damaged.
In summary, the maintenance of the plate and frame oil purifier filter plate involves many aspects, including power system inspection, filter plate replacement, clamping pressure adjustment, filter cloth and seal replacement, etc. During the maintenance process, ensure that the equipment is powered off and take corresponding safety measures to avoid accidents. At the same time, regular maintenance and maintenance of the equipment is also an important measure to prevent failures.
