Operating Instructions for Vibration Screening * Filters

Thread Content

Function and principle: The basic principle of the vibrating screening and filtering machine is to use weights (unbalanced weights) installed at the upper and lower ends of the motor shaft to convert the motor’s rotational motion into three-dimensional movements in horizontal, vertical, and inclined directions, which are then transmitted to the screen surface. Changing the phase angle of the weights at the upper and lower parts can alter the direction of movement of the material. Motor operating instructions: Motors in this series can continuously deliver the rated excitation force when the following conditions are met. 1. Vibration acceleration: Not exceeding 7g (g: gravitational acceleration). 2. Ambient temperature: Not exceeding 40°C. 3. Altitude: Not exceeding 1000m. 4. Power supply frequency: 50Hz. 5. Voltage: 380V. 6. Temperature rise: Less than 80K (resistance method). Preparations before installation: 1. Check whether the motor’s nameplate specifications meet the requirements. 2. Measure the insulation resistance using a 500-volt megohmmeter; the value obtained should indicate that the stator windings have been dried, with the drying temperature not exceeding 120°C. 3. Check all the fasteners of the motor to ensure they are not loose. 4. Check the motor surface for any damage or deformation. 5. Check whether it rotates smoothly; if there are any abnormalities, they should be resolved. 6. Check the power supply for any missing phases, and run it without a load for 5 minutes. Installation and adjustment: 1. The motor should be secured to the installation surface, which must be smooth and flat. 2. The motor can be installed horizontally. 3. The motor leads shall be four-core rubber cables of type YZ-500V; when connected to the power supply, the lead cables must not have any sharp bends and must be securely fixed to the vibrating component. 4. The motor should have a reliable grounding system; there should be a grounding device inside the motor, and the lead terminals should be marked. Grounding can also be achieved using the bolts on the base feet. 5. Adjustment of the excitation force. Use and Maintenance 1. This machine should be equipped with electrical protection devices. 2. At the beginning of operation, check the anchor bolts at least once a day to prevent them from loosening. 3. When the rotation direction of the motor does not meet the requirements, adjust the phase sequence of the power supply. 4. The motor must be kept properly lubricated; lithium-based grease (ZL-3) should be added every two weeks or so. When adding grease, use the grease cup to insert an appropriate amount of it. When sealed bearings are used, the motor is not equipped with an oil cup. 5. After the machine has been in operation for 1,500 hours in total, the bearings should be inspected; if there is severe damage, they should be replaced immediately. 6. When using the device again after it has been left unused for an extended period of time, its insulation resistance should be measured; this measurement should be taken using a 500-volt megohmmeter, and the value should be greater than 0.5 megohms. Mechanical maintenance / Routine maintenance: 1. Before starting: (1) Check whether the coarse and fine meshes are damaged; (2) Verify that each set of clamping rings is securely fastened. 2. During operation: (1) Pay attention to any abnormal noises; (2) Check if the current is stable; (3) Monitor for any unusual vibrations. 3. After use: Clean the equipment thoroughly after each use. Regular maintenance: Periodically inspect the coarse and fine meshes as well as the springs for signs of wear or damage, and check whether various parts of the machine have been damaged due to vibration. Apply lubricant to all areas that require it.
