Quality appraisal of high-frequency vibrating hammer

high-frequency vibration hammer uses the principle of high-frequency vibration to strengthen concrete structures through vibration reinforcement. The vibration frequency of high-frequency vibrating hammers is usually between 10,000Hz-20,000Hz, which is several times that of conventional vibrating hammers, so it can more effectively improve the compactness of concrete.
high-frequency vibrating hammer is often used to reinforce and repair concrete structures. For example, the surfaces of concrete structures such as beams, columns, walls, and floors can be reinforced with high-frequency vibrating hammers. Compared with traditional steel reinforcement, the advantages of high-frequency vibrating hammers include: easy to use, obvious effects, and fast speed.
In the case of high-frequency vibration hammer quality appraisal, Zhongke Testing can provide high-frequency vibration hammer quality appraisal services.

1. Check the device shell structure. While paying attention to whether the equipment shell structure is damaged, you should also check whether there are cracks in the appearance of the motor
2, and check whether the fastening screws and components of the high-frequency vibrator are complete. At the same time, pay attention to the fixation of each fastener to ensure that the fastener is fixed and not loose.
3. Check the transmission mechanism of the equipment to see if the structure is reliable to ensure that the equipment can operate normally after startup and maintain stable operating results.
4. According to the data on the nameplate, check the power supply and load of the equipment daily to see if the actual power supply and load are consistent with the data on the nameplate.
5. Check the ventilation of the equipment to ensure that the equipment is well ventilated and has good heat dissipation. At the same time, check the lubrication of the equipment bearings to ensure that the bearings are well lubricated.
6. Pull the rotating shaft of the high-frequency vibrator to check whether the rotor can rotate freely. Pay attention to whether there is any noise when the rotor rotates.
