The impact force of the channel steel punching machine comes from the hydraulic system, and if the hydraulic system wants to work stably and normally, it needs to use appropriate hydraulic oil, otherwise it will simply cause the operation fault of the hydraulic system and cause the channel steel punching machine can not normally carry out the drilling operation. So in order to enhance the function and service life of channel steel punching machine, how to select the appropriate hydraulic oil for it? < br style = "list style type: none;" / > 1. Select the type of hydraulic oil according to the use environment, and determine the viscosity of hydraulic oil required by channel steel punching machine. When selecting the viscosity, it is necessary to select according to the temperature range of the geographical location. Generally speaking, the thinner hydraulic oil can be selected in the northern region, while the hydraulic oil with a slightly higher viscosity can be used in the southern region. Because the temperature in the north is low, if the hydraulic oil viscosity is large, it is not conducive to the operation of the hydraulic system in low temperature environment. < br style = "list style type: none;" / > 2. Try to use special hydraulic oil < br style = "list style type: none;" / > if the channel steel punching machine used by the enterprise has specified special hydraulic oil, it should use special hydraulic oil according to the requirements instead of mixing with other types of hydraulic oil. If the channel steel punching machine does not have the specified hydraulic oil, the appropriate hydraulic oil brand can be selected according to the working environment and working conditions of the system. < br style = "list style type: none;" / > 3. Select hydraulic oil with high cleanliness < br style = "list style type: none;" / > in order to ensure that the channel steel punching function has good quality and use effect, it is recommended that enterprises choose genuine hydraulic oil with relatively high cost performance. Because the hydraulic oil with good brand has high purity and less impurities, there will be no impurities causing wear after using the channel steel punching machine, and the oil is not easy to deteriorate, so it can play a better role. as the hydraulic system is an important part of the channel steel punching machine, and the hydraulic oil plays a very important role in it. Therefore, when using the channel steel punching machine, enterprises should not only use the equipment according to the operation rules, but also pay attention to regularly adding and changing the hydraulic oil in the hydraulic system, so as to ensure that the quality and service life of the channel steel punching machine will not be affected.
