&Hydraulic punching machine is composed of manual pump or electric pump and working head. The oil hose is connected by quick connector, which is reliable and fast. There is no directional restriction during operation. It is convenient to assemble and disassemble. This machine is specially used for punching metal plates such as angle iron, flat iron, copper, aluminum row, etc., especially suitable for field operation in electric power, construction and other industries. What are the precautions for use and maintenance of hydraulic punching machine? < br style = "list style type: none;" / > & nbsp; & nbsp; 1. Attention should be paid to the strict and standardized operation: < br style = "list style type: none;" / > & nbsp; & nbsp; the hydraulic punching machine can only be operated after passing strict training and obtaining relevant qualification. If the understanding of the equipment is not enough, especially its structural performance and operation procedures, it is not allowed to start the equipment without authorization. At the same time, pay attention to the working process, the pressure of the low-pressure relief valve should be controlled within the specified range, so as to ensure the normal operation of the machine. < br style = "list style type: none;" / > & nbsp; 2. Pay attention to the maintenance according to the correct method: < br style = "list style type: none;" / > & nbsp; & nbsp; the hydraulic punching machine should not be overhauled and adjusted during its working process. When the equipment is found to have serious oil leakage or other abnormal conditions, such as abnormal action or abnormal noise, vibration, etc., the shelf impact manufacturer emphasizes that the machine should be shut down to analyze the causes and try to eliminate them, so as not to make the machine work with diseases. At the same time, attention should be paid to ensure that there is no pressure in the system before repairing the hydraulic station and low-pressure accumulator, and all the hydraulic oil is returned to the oil tank. Attention should be paid to the maintenance work: < br style = "list style type: none;" / > & nbsp; & nbsp; the special anti-wear hydraulic oil should be used in the hydraulic system, and the oil temperature should be controlled within the specified range. When the oil temperature is higher than the specified degree, the cooler should be used for cooling. At the same time, it should be noted that the oil filter should be cleaned with kerosene frequently. The service life of working oil should not exceed one year, and the pressure gauge should be checked and calibrated every six months.
