Precautions and Daily Maintenance of High-Frequency Dewatering Screens

To ensure the high-frequency dewatering screen operates normally, it is essential to first follow the product’s instructions for use. Additionally, specific preparations and precautions are required before startup, along with daily maintenance practices to minimize the risk of equipment failure.

1. Key Considerations When Operating a High-Frequency Dewatering Screen

(1) Monitor bearing lubrication during vibration motor operation. Under normal working conditions, after approximately 1,600 hours of cumulative operation, replace the bearing grease and clean the bearings, bearing housings, and gland seals.

(2) If the unit has been shut down or stored for more than six months, disassemble the motor for maintenance and replace the grease.

(3) Once the accumulated operating time exceeds 5,000 hours, inspect the motor bearings. Replace them with new ones if any damage is detected.

(4) After being idle for six months or longer, measure the insulation resistance between the motor stator windings and ground before restarting. When using a 500V megohmmeter, the insulation resistance must be no less than 20 MΩ.

2. Daily Maintenance of High-Frequency Dewatering Screen

Before Startup

(1) Inspect the coarse and fine mesh screens for any damage.

(2) Ensure that all transport supports have been removed.

During Operation

(1) Monitor for any abnormal noise.

(2) Verify that the current remains stable.

(3) Check for any irregular vibration patterns.

After Use

(1) Clean the equipment after each use and perform regular maintenance.

(2) Periodically inspect the coarse mesh, fine mesh, and springs for fatigue or damage. Also, check if any machine components are damaged due to vibration and ensure lubricated parts receive proper attention.

Longzhong Heavy Industry recommends timely maintenance of your high-frequency dewatering screen. Regularly check the coarse mesh, fine mesh, and springs for wear or damage, inspect the machine body for vibration-induced issues, and apply lubricating oil to moving parts as needed.
