① Regularly check whether the bearing screw is in good contact with the steel ball of the bearing sensor. When the machine is shut down for maintenance, the protective screws must be tightened first, and then the regular bearing frame can be used.
② The protection equipment shall be clean, especially the electromechanical conversion part at the force bearing mechanism of weighing frame, driving motor or tachogenerator.
③ The zero point (tare) and range of the system shall be checked regularly, and the code hanging and actual calibration shall be carried out regularly. Regularly check and adjust the belt deviation, and when the normal flow is guaranteed, the working range of the frequency converter is 15~45Hz.
④ Check and adjust the belt tension, keep the ruler on the automatic tensioning device at the specified position, keep the belt tension constant, and prevent the belt from slipping. Check whether the material is loaded on the belt eccentrically, and whether there is leakage embedded between the drive drum and the belt.
⑤ Strictly control the material particle size and moisture on the belt scale within the allowable range. If there are particles larger than 25 mm, the feeding port of the belt scale will be blocked, resulting in distortion of measurement and control, and even scratching the belt. When stacking materials in the open air in rainy days, pay attention to whether the batching silo and discharge chute are blocked, so that the measurement cannot be accurate.
The above is the brief information of the manufacturer of Xuzhou belt weigher. I hope it can help you.
