How to carry out daily maintenance of magnetic levitation blower in food factory?

The daily maintenance of magnetic levitation blower in food factory can start from the following aspects:

Appearance and environmental inspection

Cleaning the surface of the equipment: The surface of the magnetic levitation blower should be kept clean, because there may be pollutants such as dust and food residue in the environment of the food factory. Wipe the equipment shell regularly (at least once a week is recommended) with a clean and soft wet cloth to prevent dust and sundries from entering the equipment and affecting heat dissipation or operation.

Check the installation foundation and surrounding environment: check whether the installation foundation of the blower is firm and whether there is looseness or displacement. At the same time, ensure that the space around the equipment is unobstructed, free of obstacles and well ventilated. Good ventilation helps the equipment to dissipate heat, so as to avoid the performance being affected or the equipment being damaged due to overheating. Attention should also be paid to the temperature and humidity of the surrounding environment. The ideal temperature range is generally 0-40℃ and the relative humidity is 20%-80%.

Operation parameter monitoring

Monitoring pressure and flow: check the outlet pressure and flow of the blower daily through the pressure sensor and flow meter installed on the pipeline. Ensure that these parameters are within the normal range specified by the equipment. If abnormal fluctuation of pressure or flow is found, it may be pipeline blockage, leakage or equipment failure, which needs to be investigated in time.

Check the temperature and speed of the motor: observe the temperature and speed of the motor by using its own temperature sensor and speed monitoring device. Excessive motor temperature (generally should not exceed the rated temperature of the motor, such as the rated temperature of some motors is about 130℃) may be caused by overload, poor heat dissipation and other reasons; Abnormal speed may indicate that there is a problem with the motor control system or transmission parts.

Maintenance of lubrication and cooling system (although the magnetic levitation blower has no contact friction, the related auxiliary systems still need to be maintained)

Inspection of cooling system: If the magnetic levitation blower is equipped with a cooling system, such as an air-cooled cooling fan or a water-cooled cooling pipe, the operation of the cooling system should be checked regularly. For the air-cooled system, check whether the fan operates normally and whether the vent is blocked; For the water cooling system, it is necessary to check whether there is water leakage in the cooling water pipeline and whether the coolant level is normal. It is recommended to check it once a week.

Inspection of lubrication system (if any): Some magnetic levitation blowers may have a small number of lubrication points on some auxiliary parts. Check whether there is enough grease or lubricating oil at these lubricating points, and replenish or replace them at regular intervals (such as about one month) to ensure good lubrication and prevent parts from being worn.

Electrical system maintenance

Check the electrical connection: regularly (once a month is recommended) check whether the electrical terminals are loose and oxidized, and whether the wires are damaged. Loose wiring may lead to poor contact, increase resistance and overheat; Broken wires are at risk of leakage. Tighten the terminal with insulating tools and replace the damaged wires.

Check the control system: check the control system of the blower, including frequency converter, controller and other equipment. Check whether there is fault alarm information on the control screen, and whether all control buttons and indicators work normally. For the software part of the control system, it is necessary to ensure its latest version, and regularly back up important operating parameters and control programs to prevent data loss.

Replace vulnerable parts regularly.

Screen replacement: the screen at the air inlet of the blower is an important part to prevent dust and impurities from entering the equipment. According to the environmental conditions of the food factory, the filter screen should be replaced regularly (for example, every 1-3 months) to ensure smooth air intake and avoid insufficient air intake due to filter screen blockage.

Inspection and replacement of other vulnerable parts: Although the mechanical wear of the magnetic levitation blower itself is small, some auxiliary parts such as seals may age with time and use. Check the status of these vulnerable parts regularly, and replace them in time according to the wear condition to prevent gas leakage and other problems.

Maintaining records and establishing files

Record the maintenance situation: after each routine maintenance, record the maintenance date, content, problems found and solutions taken in detail. These records are helpful to track the running state of the equipment, find out the potential failure trend in time, and are also convenient for maintenance personnel to refer to during subsequent maintenance or troubleshooting.

Establishment of equipment archives: Establish complete equipment archives for magnetic levitation blower, including equipment model, purchase date, installation and debugging records, maintenance history, operation parameter records and other information. By analyzing the equipment files, we can better arrange the maintenance plan, predict the service life of the equipment and improve the management level of the equipment.
