Key points of hydraulic oil replacement for automatic cutting machine As a common industrial cutting equipment, the operator should know the equipment before taking the post, master its operation method, understand its internal structure and the working principle of the equipment, as well as some common problems that it will appear in the operation process, and also have the treatment methods. Before using the equipment, we should also carry out full position inspection of the equipment, especially its main components. If there is any problem, we should take measures to solve it, and do not let the cutting machine work with disease. Staff must pay attention to this inspection work, avoid the relatively large mistakes in the process of work, which will seriously affect the whole work. The hydraulic oil of automatic cutting machine will affect the performance and efficiency of hydraulic cutting machine if it is used for too long in the system. So we should know what circumstances the hydraulic oil needs to be replaced? This depends mainly on the degree of contamination of the oil. The following are three methods for determining the oil change period provided by the manufacturer of the automatic cutting machine: Key points of hydraulic oil replacement for automatic cutting machine (1) Visually check the oil change method. It is based on the experience of maintenance personnel, and it determines whether to change oil according to the changes of some oil routine state detected visually - such as blackening, smelling, and milky white. (2) Regular oil change method. According to the environment conditions, working conditions and oil oil change period of the oil used, the oil cutting machine equipment shall be replaced at the expiration of the time. This method is very suitable for many hydraulic equipment enterprises. (3) Sampling and testing. Regularly sample and test the oil in the oil pressure cutter, measure necessary items (such as viscosity, acid value, water, particle size and content, corrosion, etc.) and indexes. Compare the actual measured value of oil quality with the specified oil deterioration standard, and determine whether the oil should be replaced. Sampling time: the hydraulic system of general engineering machinery shall be conducted one week before oil change period. Key equipment and test results shall be filled in the technical files of equipment.
