由于确定的油箱体积较小，油箱表面的散热面积也就较小。打捆机液压系统连续

Due to the small volume of the determined fuel tank, the heat dissipation area on the surface of the fuel tank is also small. When the hydraulic system of the strapping machine is continuously working, the oil temperature may increase. When the temperature is too high, it will affect the normal operation of the hydraulic system. In order to prevent the oil temperature from rising, the hydraulic system of the baler is equipped with a separate cycle (which does not depend on the working cycle of the system but works off-line and keeps the temperature constant) oil-air cooler produced by the German Hedeke company. This kind of cooler is conducive to environmental protection and will not produce water and oil exchange. During operation, the temperature sensor sends a signal to the PLC to automatically control the start or stop of the cooling pump and fan motor to cool the oil in the hydraulic system. The structure of the hydraulic oil tank is shown in Figure 7. The structure of the hydraulic oil tank

Due to the small size of the tank, the cooling area on the surface of the tank is also small. There is a possibility that the fluid temperature will increase when the hydraulic system is working continuously, which will affect the normal operation of the hydraulic system when the temperature is too high. In order to prevent the oil temperature from rising, the bale machine hydraulic system is equipped with a separate cycle produced by The German company Herdek (operating offline without relying on the operating cycle of the system and maintaining a constant temperature) oil air cooler. This cooler is environmentally friendly, does not produce water and oil exchange, and automatically controls the start or stop of the cooling pump and fan motor through the temperature sensor, cooling the fluid in the hydraulic system. The structure of the hydraulic tank can be found in Figure 7. The structure of the hydraulic tank is shown

Because the volume of the tank is small, the heat dissipation area of the tank surface is small. When the baler hydraulic system works continuously, the oil temperature may rise. When the temperature is too high, the normal operation of the hydraulic system will be affected. In order to prevent the increase of oil temperature, the bundling machine hydraulic system is equipped with a separate cycle (independent of the working cycle of the system and working outside the line, keeping the temperature constant) oil air cooler produced by Germany hedek company. This kind of cooler is beneficial to environmental protection and will not produce the exchange of water and oil. During operation, it sends signals through the temperature sensor, and PLC automatically controls the start or stop of the cooling pump and fan motor to cool the oil of the hydraulic system.
