Maintenance of the PE jaw-crushing production line is an important part of ensuring its long-term stable operation and extending its service life. The following is a detailed introduction to the maintenance of the PE jaw-crushing production line, covering several key aspects, including lubrication, fasteners, belts, protective devices, operation, and inspection, etc.
1. Lubrication and maintenance
Selection of grease: Select appropriate grease, such as calcium-based, sodium-based, or calcium-sodium-based grease, according to the place of use and temperature conditions.
Grease filling: The grease added to the bearing seat should be 50%-70% of its spatial volume and replaced every 3-6 months. When changing oil, clean gasoline or kerosene should be used to clean the roller-bearing raceway.
Lubrication of thrust plate and thrust plate support: Before starting, an appropriate amount of grease should be injected between the thrust plate and the thrust plate support.
2. Fastener inspection
Check all fasteners regularly to ensure that they are fully tightened to avoid safety accidents and equipment damage caused by loosening.
For the connecting bolts between the toggle plate and the movable jaw, special attention should be paid to their tightening to prevent vibration and noise caused by loosening.
3. Transmission belt inspection
Check the tightness of the transmission belt to ensure that it is moderate to avoid reduced transmission efficiency and belt wear caused by over-tightening or over-loosening.
Regularly check the wear of the belt, and replace it in time if it is damaged or seriously worn.
4. Inspection of protective devices
Ensure that the protective devices are complete and intact, and any unsafe phenomena found should be eliminated immediately.
Regularly check the installation of protective devices to ensure that they are firm and reliable.
5. Operation and inspection
Before starting, carefully check whether there is ore or other debris in the crushing chamber, and if so, remove them immediately.
The machine should be started under no-load conditions, and overload is absolutely not allowed.
During the operation of the equipment, the bearing temperature should be checked frequently, and the temperature should not exceed 60 degrees. At the same time, check whether the screws of each part are loose, whether the spring tightness is normal, and whether the motor is overloaded.
During crushing, if the material in the crushing chamber is blocked and causes the machine to stop, the motor should be turned off immediately, and the material must be removed before starting.
During the operation of the equipment, it is not allowed to be cleaned or wiped, and it should be cleaned after the machine stops.
6. Maintenance cycle and content
Maintenance cycle: 1-6 months for minor repairs, 1-2 years for medium repairs, and 3-5 years for major repairs.
Maintenance content:
Minor repairs: Replace worn linings and toggle plates, adjust the gap of the discharge port, tighten the bolts of various parts, dredge the oil circuit, etc.
Medium repairs: In addition to minor repairs, replace or repair the tooth plate, adjust and repair the side plate and toggle plate pads, check or replace the pull rods and pull rod springs, etc.
Major repairs: In addition to medium repairs, repair or replace various bearings, adjust the machine base, repair the foundation, etc. All equipment should be dismantled and cleaned, thoroughly inspected, and major repairs should be accepted and tested.
Through the implementation of the above maintenance measures, the stable operation of the PE jaw-crushing production line can be ensured, the failure rate can be reduced, and the service life of the equipment can be extended. At the same time, it also brings higher production efficiency and economic benefits to the enterprise.
