A professional belt conveyor manufacturer will discuss with you today the stability of the hydraulic system in belt conveyors. The hydraulic system of a belt conveyor uses oil as the transmission medium, and it consists of several components: 1. The power unit of the belt conveyor – the hydraulic pump, which converts the input mechanical energy into pressure energy of the liquid; 2. The actuating unit of the belt conveyor – the hydraulic cylinder, whose function is to transform the pressure energy of the working fluid back into mechanical energy, thereby driving the movement of the load attached to the hydraulic cylinder; 3. The control unit of the belt conveyor – including pressure valves, flow control valves, and universal control valves, which, through their control and regulation, manage the pressure, flow rate, and direction of the fluid within the hydraulic system, ensuring that the required force, speed, and direction are provided to each component. 4. Auxiliary components of the belt conveyor – these include oil tanks, pipes, oil filters, accumulators, and indicating instruments; their role is to ensure the safety and proper operation of the system. With the further development of industrialization and the increasing level of mechanization and automation, higher demands have been placed on the standardization and integration of hydraulic components and hydraulic systems, which led to the emergence of hydraulic stations composed of hydraulic systems. At present, hydraulic technology has made significant contributions to the needs and development of China’s socialist modernization drive. Hydraulic technology, particularly hydraulic module technology, is widely used in many industrial sectors in China. Hydraulic technology is evolving toward higher pressure, higher speed, larger flow rates, greater power, and lower noise. Computer-aided design of hydraulic systems has been widely applied, and it will drive further development in hydraulic technology. Many unsafe factors that arise during the operation of the hydraulic control system for belt conveyors are irregular in nature, such as abnormal loads, power outages, and operational errors by the operators; therefore, appropriate safety circuits or protective measures must be in place to ensure the safety of both the operators and the system equipment. For example, to prevent the working components from drifting, sliding down, or running too fast, there should be circuits for compression, speed limitation, and balancing. Therefore, in the design schematic, in order to prevent the piston rod of the plug cylinder from falling downward due to gravity during operation, a hydraulic check valve must be installed at the oil outlet of the hydraulic cylinder to avoid this phenomenon, thereby increasing the safety factor of the system’s operation. Considering the production costs and cycle time of belt conveyor systems, it is necessary for the system’s structure to be simple, with as few auxiliary components as possible. Standard components should be used wherever possible, in order to reduce the need for custom-designed components and thus lower production costs and shorten production times. Ensure that the heat generated by the system does not affect its operation ； The pressure gauge, volume, and mechanical aspects of the hydraulic system contribute to overall energy losses; these energy losses are converted into heat, which raises the temperature of the system. An increase in system temperature can have many negative effects and impair the system’s performance. For example, an increase in the viscosity of the lubricant can lead to increased leakage, resulting in unstable speeds. It can also cause variations in the gaps between moving parts with different expansion coefficients, leading to jamming and loss of functionality. Furthermore, it can cause deformation of the machine components and damage to their precision; therefore, it is necessary to control the temperature of the system to ensure the proper operation of all working components. In the hydraulic control system of belt conveyors, factors such as changes in the movement speed of hydraulic cylinders, sudden disappearance or emergence of working loads, and impact loads can often cause shocks within the system. Such shocks can affect the normal operation of the system; therefore, it is necessary to take certain measures to eliminate or reduce these shocks.
