Vibrating screen is an indispensable sand-making equipment in the sand-making production line, mainly used to screen materials. In the stone production line, we will be equipped with vibrating screens. The vibrating screen equipment is a kind of vibrating screening mechanical equipment suitable for dry screening of wet and fine-grained materials that are difficult to screen. When the vibrating screen fails to start normally, the user should immediately stop and check the vibrating screen. Recently, many customers have asked why the vibrating screen cannot be started when it is running? The following polyurethane screen manufacturers will give you an analysis of what to do when the vibrating screen cannot be started.
1. The reason why the vibrating screen cannot be started
1. Check the power supply
First check whether the power supply or click fails, if the power supply or click fails, replace the type part. If the element is damaged, it needs to be replaced in time. Pay attention to the stability of the voltage. If the voltage is lower than the rated voltage when starting, it will easily cause the vibrating screen to malfunction. Therefore, keep the voltage stable when the vibrating screen is working.
2, check the exciter
The vibrating screen is vibrated by the vibration exciter to realize the screening work. If the vibration exciter fails, the vibrating screen cannot be started. The exciter needs to maintain a good lubrication state, and it needs to use professional grease.
If the grease is agglomerated or solidified, it will not be able to perform the lubrication function. Therefore, it is necessary to check the lubrication of the exciter regularly and add lubricating oil in time.
3, check the vibrating screen equipment itself
Check whether the vibrating screen itself is malfunctioning. For example, if the specified feeding value is exceeded during feeding, the vibrating screen will be blocked, and the accumulation of materials will cause the vibrating screen to work in accordance with the expression and finally fail to start. If the vibrating screen cannot be started due to improper feeding, the screen needs to be cleaned to ensure the normal screening function of the screen.
2. Matters needing attention when the vibrating screen is started
1. Before starting the vibrating screen, check that the screws and locking parts are firm and whether they are loose.
2. Check whether the screen of the vibrating screen is tightly pressed, and whether the connection between the motor, rubber pad, screen body and frame is intact.
3. Check whether the power supply voltage of the vibrating screen is stable.
4. Check the vibrating motor of the vibrating screen, remove the end cover of the motor, check whether the fan-shaped block and the relative angle of the motor are consistent, and check whether the installation angles of the two motors are consistent.
5. Check the feeding device of the vibrating screen.
6. Check the tightening gate of the vibrating screen.
7. Check whether the inlet and outlet hoses of the vibrating screen are tightly connected. Do not connect too tightly.
8. Carry out no-load test run on the vibrating screen. The reciprocating linear motion is performed during the test run, and there is no collision between the screen body and the frame, and there is no abnormal noise or abnormal trajectory movement during operation. After 10-15 minutes, tighten all bolts.
The following vibration screen abnormalities are the reasons and solutions that Jiding Environmental Protection Technology Co., Ltd. summarized according to the needs of customers.
1. The voltage required by the vibrating screen is 380v three-phase power, please make sure you are using a three-phase power supply.
2. The motor is damaged and the motor needs to be replaced.
3. The electrical components in the control circuit are damaged, and the electrical components need to be replaced.
4. Insufficient voltage can be solved by changing the power supply.
5. Too much material on the screen surface has accumulated, and the material on the screen surface needs to be cleaned.
6. ??If the vibrating screen fails, the failure can be eliminated by repairing the vibrator.
7. The grease in the vibrating screen becomes thick and agglomerated, and the vibrator needs to be cleaned and updated with suitable grease.
Polyurethane screen manufacturers have introduced to you the reasons why the vibrating screen cannot be started. Large vibrating screens and failure to start are common faults. Therefore, technicians should have good habits during operation to ensure the normal operation of the vibrating screen and improve the performance of the vibrating screen. Productivity.
