The hydraulic system of asbestos tile equipment is an important part of the equipment.According to the basic composition of the hydraulic circuit,the hydraulic system can be divided into an open system and a closed system.Open system:The pressure oil output by the pump returns to the fuel tank after completing the work task.It is widely used,but the fuel tank should be large enough.A system with cylinders is definitely an open system.Closed system:The pressure oil output by the pump returns to the pump from the actuator to form a closed circuit.It is mostly used for the driving of vehicles,and the booster pump is used to replenish the oil,and the flush valve is used to change the oil locally.Compared with the open circuit,the closed circuit has high efficiency(especially the effect of power recovery during braking),less heat generation,and the actuator moves forward and backward smoothly;but the pump must be a dual-flow variable pump.   　　The hydraulic system is the key to the molding of asbestos tile equipment.The hydraulic devices of Fang Ruizheng and asbestos tile equipment are arranged neatly,with clear directions and reliable connections.The control system controls the direction,pressure and flow of hydraulic oil flow.With the development of the building materials manufacturing equipment industry,more and more new technologies have been transported to the building materials equipment,and the requirements for the hydraulic system of asbestos tiles have also increased,not only to run stably,but also to achieve greater pressure,Only in this way can the density of asbestos tiles be increased,thereby improving the performance of asbestos tiles.
