The promotion of economy has promoted the continuous progress of industry. We all know that there are many kinds of equipment in industry, including openers. Long-term use will cause failures, and openers are no exception. Next, let me tell you how to use the opener! I hope it will be helpful to everyone. Maintenance method: First check whether the power socket, plug and power cord are deoxidized and damaged. If not, plug in the power and leave the machine. When the motor is powered on and does not rotate, apply a certain external force on the wind vane (never use your hands) and gently touch the wheel, and the motor will not rotate. It may be that the recycled cotton has locked the motor. In this case, it is generally necessary to shut down and power off the motor to clean it. Another situation is that it does not rotate when powered on, and it can rotate when external force is applied, but there is a weak current noise in the motor, which is caused by a slight leakage of the starting capacitor. If the current noise is too large and the motor cannot start at all, it can be concluded that it is caused by a short circuit in the starting capacitor. Maintenance steps: 1. First, check whether the bearing is in a good lubrication state: oil should be added frequently to keep it lubricated. 2. Check whether all fasteners are tightened. Check whether the drive belt is installed correctly and in good condition. If the belt is found to be damaged, it should be replaced in time. When there is oil on the belt or pulley, clean it with a clean rag. 3. Check whether the protective device is intact. If any unsafe phenomenon of the protective device is found, it should be eliminated in time. 4. Check whether there is any material or other debris in the damaged cavity, and remove it if necessary. Prevent fire because of unnecessary losses. 5. Check the rack and machine fixing screws regularly. The use of the opener provides strong support for our production reuse. It can be said that the value of the opener will continue to increase in the next few years. As for the quality inspection method of the opener mentioned above, it is introduced here today.
