Vibrating Screening Machine Maintenance Tips

1. Regular cleaning

The vibrating screening machine will have residual materials during use. If it is not cleaned in time, the materials will clump or corrode the equipment. After daily use, the equipment needs to be turned off and the power is turned off, waiting for it to be completely still. Use a soft brush to gently brush the surface of the screen to remove the attached materials. For stubborn dirt, soak it in warm water to soften it, and then use a soft brush to clean it. Wipe the material dust on the equipment casing and bracket with a clean rag to keep the appearance of the equipment neat and tidy. Regular deep cleaning, disassemble the screen every week, rinse it with a high-pressure water gun, and after cleaning all parts, carefully wipe or dry the equipment to prevent moisture residue from causing rust on the equipment or short circuit of electrical components.

2. Check fasteners

When the vibrating screening machine is running, vibration can easily loosen fasteners such as screws and bolts, causing equipment failure or even accidents. Before daily use, check all exposed fasteners, including screen clamping bolts, motor fixing screws, equipment and base connection bolts, etc. If loose, tighten them immediately with a suitable wrench. Check the fasteners of key parts thoroughly every week, such as the fixing bolts of the exciter and the connecting bolts of important supporting structures. When checking, first visually check for signs of looseness, and tighten them one by one with a wrench if necessary. Systematically check and tighten all fasteners of the equipment every month, record the status of the fasteners, focus on marking the parts that are often loose, analyze the reasons and take measures.

3. Maintenance of bearings

Bearings are the core components of the vibration screening machine and are crucial to the operation accuracy and life. After the equipment has been running for 50 hours, replace the grease for the first time, and then replace it every 200-300 hours of operation. The grease filling amount is 1/3-1/2 of the bearing space. Check the bearing temperature every week. The normal operating temperature does not exceed 70℃. If the temperature rises abnormally, check the bearing lubrication and wear. Carefully check the bearing for abnormal noise and vibration every month, check it with a stethoscope or professional instrument during operation, and repair and replace it in time if abnormalities are found. Professionally maintain the bearings every six months, disassemble the bearings, clean and inspect the inside, replace the seals and other wearing parts to ensure the bearing performance.

4. Maintain the motor

The motor is the power source of the vibrating screening machine and needs regular maintenance. Check the motor temperature every week. The temperature rise should not exceed the nameplate regulations. Generally, the motor housing temperature should not exceed 80℃. Otherwise, check for problems such as motor overload and poor ventilation. Check the motor junction box every month, tighten the terminal to prevent virtual connection and short circuit, clean up dust and debris, and keep the junction box dry and clean. Check the motor belt (if any) every quarter, adjust the tightness, visually check the degree of belt wear and aging, and replace it in time if abnormal. Perform a comprehensive inspection of the motor every year, disassemble the motor, check the wear of the rotor, stator, bearing and other parts, perform insulation resistance test, and perform maintenance when necessary.

5. Maintain the screen

The screen is a key component. Regular inspection and maintenance can ensure the quality and efficiency of screening. Before daily operation, check whether the screen is damaged, deformed, or loose. Replace and repair it in time if abnormal. Clean the screen every week, brush the surface lightly with a soft brush to remove attached materials, and soak and soften stubborn dirt in warm water before cleaning. Avoid scratching with hard objects or directly washing with a high-pressure water gun to prevent damage to the screen. Check the tension of the screen every month to ensure that the tension is even and moderate. Too tight or too loose will affect the screening effect and the life of the screen. Check the sealing of the screen and the screen frame every quarter. If the sealing is not tight, deal with it in time to prevent material leakage from affecting the screening efficiency. According to the frequency of use and the degree of wear of the screen, replace the screen regularly. Generally, the service life of the screen is 1-3 months. If the wear is serious, replace it in time to ensure the screening quality.

6. Check the sealing performance

The sealing performance of the vibration screening machine is crucial to prevent material leakage and the entry of external impurities. Check the sealing parts of the equipment every day, such as the sealing strips or gaskets between the screen box and the base, the discharge port, etc., and replace them in time if they are damaged, aged, or deformed. Check the sealing of the equipment lubrication system and hydraulic system (if any) every month to check for oil leakage, check the seals and pipeline connections, and repair them in time if problems are found. Check the sealing of the equipment protective cover, observation window and other parts every quarter to ensure that they are well sealed to prevent external debris from entering the equipment and affecting normal operation.
