Common failure phenomenon: the entire hydraulic system of the waste paper baler has no pressure or insufficient pressure.
Common causes of failure: the overflow valve fails, and the oil pump is not working properly.
Solution: Check the type of overflow valve used in the waste paper baler equipment. If it is a pilot-operated overflow valve, there are many causes.
1. The overflow valve is stuck or the solenoid fails. If the overflow valve is stuck, clean the overflow valve and reinstall it. If it is electromagnetic failure, you need to check whether the circuit is open, and check whether the coil of the overflow valve is burned. If there is a problem with the circuit, repair the circuit; if the coil burns out, the coil needs to be replaced.
2. If it is the internal wear of the overflow valve, the overflow valve needs to be replaced at this time.
Waste paper baler is an environmental protection equipment that uses hydraulic principles to compress waste paper and waste cardboard into blocks, which is beneficial to waste paper storage, transportation and utilization. https://www.nickbaler.net
Some customers have responded that the crocodile shearing machine has no strength when cutting metal plates, and sometimes the blade cannot be lowered when idling. The reason for this type of situation is mostly because the hydraulic oil has been used for a long time and has not been replaced in time. Let's talk about the selection method of hydraulic oil for crocodile shearing machine:
1. The hydraulic oil must not contain steam, air and other impurities that are easy to vaporize and produce gas, otherwise it will form bubbles, cause the working mechanism to vibrate, and affect the stability of the work.
2. Does not corrode mechanical parts and damage sealing devices, that is, does not contain water-soluble acids and alkalis.
3. Under working temperature and pressure, it has excellent lubricity, shear stability and certain oil film strength.
4. The chemical stability is good. It should not be oxidized to form gum during storage and working. It can be used for a long time without deterioration. When the temperature, pressure and flow rate in the system change, it still maintains its original properties. Deterioration, no colloidal precipitation such as asphalt and tar will be precipitated.
NICKBALER crocodile shearing machine adopts hydraulic drive, which has the characteristics of convenient operation, stable and reliable, low failure rate, convenient and simple maintenance. https://www.nickbaler.net
The cutting edge of the metal shearing machine blade should be kept sharp, and the cutting edge should be blunt or damaged. It should be sharpened or replaced in time. When multiple people are operating, there should be a special person to command, and the cooperation should be coordinated.
It is forbidden to cut two materials of different specifications at the same time on the gantry shearing machine, and no overlapping cutting is allowed. It is forbidden to use the handle to facilitate the operation under the pressure plate when cutting the material. When cutting the material, it should be pressed by another iron plate. At least 200 mm.
When the metal shearing machine has serious oil leakage or abnormal phenomena during work, it should be shut down immediately, the cause should be analyzed and the fault should be eliminated, and it should not be forced to run with illness.
When adjusting the pump, valve, and pressure gauge of the metal shearing machine, it must be carried out by experienced skilled workers. If the pressure gauge is found to be faulty, it should be checked or updated immediately.
The steel plate cut by the metal shearing machine should be transported away in time, and stacked neatly according to the specifications, and the leftover materials should be placed in the specified place.
The NICKBALER metal shearing machine has reliable performance, convenient operation and simple maintenance. Diesel engines can be used as power where there is no power supply. https://www.nickbaler.net
The operation and maintenance personnel of the gantry shearing machine must be trained after taking the job. The operator must have electrical, mechanical and hydraulic knowledge, and should be proficient in the composition, location, function, characteristics, and easy problems of the various parts of the shearing machine. , Without learning, those who do not understand the structure, performance and operating procedures of the shearing machine are not allowed to operate.
Safety precautions for gantry shears:
1. When the shearing machine is running, irrelevant personnel are not allowed to enter the shearing machine work site (including the scrap storage area to be cut). When someone is in a dangerous position on the site, the shearing machine should be stopped completely or partially.
2. After blade replacement or other operations are completed, the safety pin of the scissors slider and the pressure block of the press must be completely pulled out, otherwise, the safety pin will be cut off when starting, and the equipment will be damaged.
3. After the work is over, the lower parts such as the gland, pressing block, and scissors slider should be lowered to a low position, and the pushing slider should be returned to the position to ensure safety.
4. When the machine has a serious oil leakage or an abnormal phenomenon occurs during work, it should stop immediately, analyze the cause and eliminate the fault, and do not work with illness.
5. When adding materials, do not add too much to the waste materials with high density and hardness, otherwise the shearing blade will be worn too much, and the shearing blade will even be scrapped, thereby affecting the use of the machine, or even destroying the machine.
NICKBALER gantry shears are widely used in metallurgical plants and scrap steel processing and recycling units. It is an effective equipment for metallurgical charge processing and profile cutting. https://www.nickbaler.net
