Reasons for No-Load Test Run of Vibrating Screen | RFQ Sourcing Details

Reasons For No-Load Test Run Of Vibrating Screen Before installing the vibrating screen, carefully check it first.

Due to the long storage time of manufactured finished products, such as bearing rust, aging of seals or damage in the process of handling, when encountering such problems, it is necessary to replace new parts.

Also, for example, the vibration exciter should be rust-proof and injected with antirust oil before leaving the factory. It should be replaced with lubricating oil before it is officially put into operation.

After the installation of the shale shaker, it is necessary to carry out the no-load test run and make a preliminary inspection. If there is a problem in the installation, it is necessary to make necessary adjustments. The no-load test run time of the vibrating screen shall not be less than 8 hours.

During this time, observe whether the screen starts smoothly and quickly, whether the vibration and operation are stable, and whether there is any special noise. Observe whether the amplitude meets the requirements through the amplitude. When the screen is running, the screen box vibration should not produce sway.

If yaw occurs, the reasons may be that the height difference between the springs on both sides is too large, the tension of the hanging wire rope is uneven, the rotating shaft is not horizontal, or the triangular belt is too tight, which should be adjusted accordingly.

Within 4 hours of driving, the bearing temperature will increase and then remain stable. Generally, the high temperature should not exceed 75 ºC and the temperature rise should not exceed 40 ºC.

If there is abnormal noise or the bearing temperature rises sharply after starting, it is necessary to stop the machine immedia d before starting. After running for 2-4 hours, stop the machine to check whether each connecting part is loose. If it is loose, fasten it and run it again for 8 hours.

If there is no fault, the installation of the vibrating screen can be accepted.

Overview of ultrasonic vibrating screen The ultrasonic vibrating screen is an ordinary rotary vibrating screen with an ultrasonic mesh frame, which converts the ultrasonic waves into high-frequency mechanical waves through an ultrasonic power source and an ultrasonic transducer, and tr
