The blower machinery has a long service life, and at the same time it is relatively simple to maintain. If it is a large-scale production enterprise, there are more machines deployed.
Frequent maintenance is required to achieve a better state of use, otherwise it will cause large power consumption or failure due to improper maintenance or dust intake. As a maintenance team, what steps and methods should be followed in daily work?
Maintenance personnel should hold relevant certificates and have relevant knowledge of electrical engineering and machine principles.
First, cut off the power and check the integrity of the external circuit to see if the wire skin is intact and peeled off, and if there is a short circuit or leakage risk due to bad conditions, which affects the safety of personnel.
Second, although different fans have different structures, they are basically composed of several parts. Remove the screws of the casing to remove the rust, and check the integrity of the sealing rubber ring.
If it is damaged and needs to be replaced, because the equipment has requirements for air tightness, use a brush or other cleaning equipment to remove dust and rust.
Third, check the bearing. Bearing is the basic component related to the smooth operation of the fan. It is easy to loosen during operation throughout the year, resulting in a larger gap, and the vibration amplitude is getting larger and larger. For a 2000 speed device, the measured amplitude does not exceed 0.5mm, 3000 The speed of the equipment is controlled at 0.7mm to be qualified, and some bearings need to be lubricated regularly.
Fourth, focus on checking the integrity of the blades, the tightness of the fit, and the working noise. If the noise is too large, it is estimated that there is a gap with the bearing or the blade is defective, resulting in uneven air flow during the movement. Replacement can be considered. Metal blades can be repaired by welders if they are made of iron.
Fifth, motor inspection Start the motor, check the speed, and clean up the dust at the same time. Some motors with burn marks can be scrapped.
Sixth, the maintenance of electrical equipment must be carried out under the premise of power failure. After the maintenance is completed, the integrity of the circuit needs to be checked to ensure the insulation environment, and the exposed joints are treated with electrical tape, and then during the installation process, ensure that all parts are installed. Check the air-tightness after completion, and the rated noise and speed must be reached during the test machine, and no hand should be put into the rotating blade.
Seventh, the maintenance time of the equipment. A new machine needs to be replaced one month after the installation of the lubricating oil, the second replacement is 60 days later, and the third time is one year later. The maintenance team needs to perform the above-mentioned process of maintenance on the equipment every month. , To ensure the long-term effectiveness of its work.
The use and maintenance of the blower is very simple. Like most electrical equipment, it is regularly disassembled, inspected, lubricated, and replaced. The service life of a piece of equipment ranges from several years to several decades.
If the maintenance is proper, it can effectively help companies reduce investment, ensure work safety, and eliminate the hidden dangers of circuit fires. Every large enterprise should train maintenance personnel with knowledge of electricity use and supervise regular work.
