1、 Regular inspection and cleaning

1. Equipment inspection：
   • Regularly inspect the various components of the vacuum industrial suction machine, including the vacuum pump, filter, conveying pipeline, suction port, etc., to ensure that they are in good working condition.
   • Check the sealing condition of various pipelines and pipe joints, and replace pipe joints or seals in a timely manner to prevent air leakage.
2. internal cleaning：
   • Cut off the power supply of the vacuum suction machine and ensure that cleaning is carried out in a non powered state.
   • Open the hopper and pipeline connection of the feeding machine to remove any remaining materials. Tools such as brooms and shovels can be used. For materials adhered to the inner wall of the equipment, wipe them with a damp cloth or blow them clean with compressed air.
   • Special attention should be paid to cleaning the interior of the vacuum pump to prevent material residue from corroding the pump body. You can follow the operation manual of the vacuum pump to disassemble the relevant components for cleaning, but be careful not to damage the parts during the disassembly process.
3. External cleaning：
   • Wipe the equipment casing with a clean damp cloth to remove dust, oil stains, and material stains from the surface.
   • For stubborn stains, mild cleaning agents can be used, but avoid contact with electrical components of the equipment to prevent short circuits or corrosion.

2、 Replacement of vulnerable parts

1. Butterfly valve sealing ring：
   • After long-term use, the sealing ring of butterfly valves may experience wear and aging, leading to air leakage, reduced vacuum degree, low suction capacity, or inability to move. Regularly inspect and replace worn sealing rings.
2. filter module：
   • Long term insufficient air pump pressure or decreased blowback effect can cause filter blockage. Regularly check the working status of the filtration module and clean or replace the filter element if necessary.
3. vacuum pump oil：
   • Check the oil level of the vacuum pump to ensure that it is within the normal range. If the oil level is too low, add vacuum pump oil that meets the equipment requirements.
   • Observe the color and texture of the vacuum pump oil. If the oil is cloudy, black, or has an odor, it indicates that the oil has been contaminated and needs to be replaced with new oil.

3、 Lubrication and rust prevention

1. Lubricate moving parts：
   • Add an appropriate amount of lubricating oil or grease to the various moving parts of the feeding machine, such as the rollers, chains, bearings, etc. of the conveyor belt.
   • For parts that require regular lubrication, it is necessary to choose the appropriate lubricant according to the equipment manual and ensure that the lubricant is evenly applied to reduce component wear.
2. rust prevention treatment：
   • For the metal surface of the equipment, especially the parts that are prone to rust, such as pipeline interfaces, brackets, etc., a layer of anti rust oil or anti rust paint can be applied.
   • Before applying rust inhibitor, the metal surface should be cleaned thoroughly to remove oil, rust, and dust, in order to ensure the adhesion effect of the rust inhibitor.

4、 Electrical system inspection

1. Power cord inspection：
   • Check whether the power cord of the equipment is damaged or aged. If there are any problems, replace the power cord in a timely manner to prevent leakage accidents.
2. Electrical component inspection：
   • Open the control box and check the internal electrical components, such as contactors, relays, fuses, etc., to see if there are any issues such as contact burnout, looseness, overheating, discoloration, etc.
   • For problematic components, they should be repaired or replaced in a timely manner.
   • Clean the dust inside the control box by using compressed air or a vacuum cleaner to maintain good heat dissipation of electrical components and avoid short circuits or malfunctions caused by dust accumulation.

5、 Long term disuse treatment

1. Equipment cleaning：
   • When the equipment is not used for a long time, it needs to be cleaned and maintained to ensure that there are no residual materials or impurities inside the equipment.
2. rust prevention treatment：
   • Perform rust prevention treatment on the metal surface of the equipment to prevent rusting.
3. storage environment：
   • Store the equipment in a dry, ventilated, and non corrosive gas environment to avoid moisture or corrosion.
