The automatic waste paper hydraulic baler is noisy and vibrates what is going on

Dec 23, 2020

    The automatic waste paper hydraulic baler will produce a certain amount of noise in actual production. The noise of the waste paper hydraulic baler is also inevitable. However, the sound and vibration produced by the normal baler during the production process should be within a controllable range. The abnormal noise and vibration generated during production must be checked and hidden dangers removed in time. There are 4 sets of feeding devices for the scrap metal baler, each of which corresponds to a baling head. Each set includes a baling line conveying device and a baling line reverse tension device. The main rail seat of the waste paper hydraulic baler is mainly composed of two wear-resistant steel rails on the surface. The wheels of the compression frame are guided to run along the outer sides of the two tracks, and hydraulic cylinders that push the compression frame to operate are arranged in them. In addition, there is a complete set of hydraulic stations in addition to mechanical components. It can be seen from the above description that various movements of the waste paper hydraulic baler are completed by fluid power. With the increasing awareness of environmental protection, waste paper balers have played a great role. Some waste paper can be reused, and it is becoming more and more accepted by everyone. Domestic waste paper balers have been In constant innovation, we are constantly following the development of some foreign advanced technologies. Mineral water bottle packing machine This product has the characteristics of good rigidity, toughness and stability, beautiful appearance, convenient operation and maintenance, safety and energy saving, and low investment cost of equipment basic engineering. It is widely used in all kinds of waste paper factories, waste recycling companies and other units and enterprises. It is suitable for the packaging and recycling of waste paper, plastic straw, etc. It is a good equipment to improve labor efficiency, reduce labor intensity, save manpower, and reduce transportation costs. There are many factors that determine the abnormal noise and vibration of the fully automatic baler, but the main ones are the following aspects, we must focus on checking. When there is gas in the oil suction line, serious noise is generated. On the one hand, the oil suction height may be too high, the oil suction pipe is too thin, the resistance is too large, the oil pump speed is too high, the oil tank is not well ventilated, the replenishment pump does not supply enough oil, and the oil is too much. Stickiness or clogging of the oil filter prevents the oil from filling up the suction space of the oil pump, and separates the air dissolved in the oil, causing cavitation. On the other hand, the waste paper baler may not be sealed in the suction pipe. Well, the oil level is too low, and the oil filter is partially exposed, making it suck in a lot of air while absorbing oil. Find the definite cause from these possible causes and take corresponding measures to eliminate it. After inspection, there is no problem in all items, the noise and vibration may be caused by the poor quality of the oil pump or motor. The flow rate (unit: cubic meter per second) of the oil pump and the motor is pulsating, the oil trapping phenomenon cannot be eliminated well, and the blade or piston jamming will cause noise and vibration. Disassemble, clean and check the manufacturing quality (mainly the size of the trapped oil unloading tank and the fit of the relative moving parts). For unqualified parts, the waste paper baler should be repaired or replaced. Vibration may also be caused by some reasons: large coaxiality error of the output shaft of the motor and the input shaft of the oil pump or loose coupling, causing the vibration of the oil pump; the pipe is slender and has many elbows but not fixed, and the flow rate in the pipe is high. Cause the vibration of the pipeline (if there is significant vibration in a section of the pipe, the root cause of the failure may be incorrect pipeline selection or installation); the overflow valve or other valve of the waste paper baler resonates or the valve damping is too small, resulting in greater vibration, Causes the fluctuation of oil pressure; the reversing valve moves too fast, causing shock and vibration when reversing; the vibration of the servo system is mainly due to improper parameter selection (especially the opening amount of the follower valve), waste paper baler The elastic deformation of the pipe is too large or the gap in the feedback connection. The impact sound generated by the sliding valve hitting the valve body or the valve core hitting the valve seat is often an important cause of the noise of the waste paper hydraulic baler. If this happens, take care to take appropriate buffer measures. The system contains a lot of air, which can also cause noise. Therefore, the waste paper baler must be exhausted when the system starts to work. If any small hidden danger is not dealt with in time, it may cause serious consequences. We find that the problem must be solved in time. This will not only improve the working environment of our workers, but also increase the service life of the equipment and create more value for us.
