A large hydraulic system, also known as a hydraulic pump station, is an independent hydraulic device that supplies oil according to the requirements of the driving device (main engine) and controls the direction, pressure, and flow rate of the oil flow. It is suitable for various hydraulic machinery where the main engine and hydraulic device can be separated. After purchasing, users only need to connect the hydraulic station to the actuator (oil cylinder and oil motor) on the host through oil pipes, and the hydraulic machinery can achieve various specified actions and work cycles.
Structure of Large Hydraulic System:
The hydraulic system consists of two parts: signal control and hydraulic power. The signal control part is used to drive the control valve action in the hydraulic power part.
The hydraulic power part is represented by a circuit diagram to indicate the interrelationships between different functional components. The hydraulic source contains a hydraulic pump, an electric motor, and hydraulic auxiliary components; The hydraulic control part contains various control valves, which are used to control the flow rate, pressure, and direction of the working oil; The execution part contains hydraulic cylinders or hydraulic motors, which can be selected according to actual requirements.
When analyzing and designing practical tasks, block diagrams are generally used to display the actual operating conditions of the equipment. Hollow arrows represent signal flow, while solid arrows represent energy flow.
The action sequence in the basic hydraulic circuit of the crushing bed hydraulic system includes the direction change and spring reset of the control element (two position four-way directional valve), the extension and retraction of the actuating element (double acting hydraulic cylinder), and the opening and closing of the relief valve. For the execution and control components, the presentation is based on corresponding circuit diagram symbols, which also prepares for introducing circuit diagram symbols.
According to the working principle of the system, you can sequentially number all circuits. If * * * * execution element number is 0, then the control element identifier associated with it is 1. If the component identifier corresponding to the extension of the executing element is even, then the component identifier corresponding to the retraction of the executing element is odd. Not only should hydraulic circuits be numbered, but actual equipment should also be numbered to detect system failures.
The DIN ISO1219-2 standard defines the numbering composition of components, which includes the following four parts: equipment number, circuit number, component identifier, and component number. If there is only one type of device in the entire system, the device number can be omitted.
In practice, another numbering method is to sequentially number all components in the hydraulic system, and in this case, the component numbers should be consistent with the numbers in the component list. This method is particularly suitable for complex hydraulic control systems, where each control circuit corresponds to its system number.

Development of Large Hydraulic Systems:
In 1795, Joseph Braman (1749-1814) from England used water as a working medium in London and applied it to industry in the form of a hydraulic press, giving birth to the world's * * * hydraulic press machines. In 1905, the working medium was changed from water to oil, which was further improved.
****After World War II (1914-1918), hydraulic transmission was widely used, especially after 1920, with even faster development. Hydraulic components only began to enter the formal industrial production stage in the late 19th and early 20th centuries. In 1925, F. Vikers invented the pressure balanced vane pump, laying the foundation for the gradual establishment of modern hydraulic component industry or hydraulic transmission. G. Constantimsko's theoretical and practical research on energy wave transmission in the early 20th century; In 1910, contributions to hydraulic transmission (hydraulic couplings, hydraulic torque converters, etc.) led to the development of these two fields.
****During World War II (1941-1945), hydraulic transmission was used in 30% of American machine tools. It should be pointed out that the development of hydraulic transmission in Japan lagged behind countries such as Europe and America by nearly 20 years. Around 1955, Japan rapidly developed hydraulic transmission and established the "Hydraulic Industry Association" in 1956. In the past 20-30 years, Japan's hydraulic transmission has developed rapidly and occupies a position of *********.
Precautions for Large Hydraulic Systems:
People with some mechanical knowledge know that energy can be converted into each other, and applying this knowledge to hydraulic systems to explain the power loss of hydraulic systems is * * * *. However, hydraulic system power can cause energy loss, resulting in a decrease in the overall efficiency of the system. On the other hand, the lost energy will be converted into heat energy, causing the temperature of the hydraulic oil to rise, the oil to deteriorate, and hydraulic equipment to malfunction. Therefore, when designing hydraulic systems, while meeting usage requirements, full consideration should also be given to reducing system power loss.
****From the perspective of power source - pump, considering the diversity of actuator working conditions, sometimes the system requires high flow and low pressure; Sometimes small flow rates and high pressure are required. Therefore, it is advisable to choose a pressure limiting variable displacement pump, as the flow rate of this type of pump varies with changes in system pressure. When the system pressure decreases, the flow rate is relatively large, which can meet the fast stroke of the actuator. When the system pressure increases, the flow rate decreases accordingly, which can meet the working stroke of the actuator. This can not only meet the working requirements of the actuator, but also make the power consumption more reasonable.
****When hydraulic oil flows through various hydraulic valves, pressure loss and flow loss are inevitable, and this part of energy loss accounts for a large proportion of the total energy loss. Therefore, choosing a hydraulic actuator reasonably and adjusting the pressure of the pressure valve is also an important aspect of reducing power loss. The flow valve is selected according to the flow regulation range in the system, and its small stable flow rate can meet the usage requirements. The pressure of the pressure valve should be as low as possible while ensuring the normal operation of the hydraulic equipment.
Thirdly, if the actuator has speed regulation requirements, then when selecting the speed regulation circuit, it is necessary to meet the speed regulation requirements while minimizing power loss as much as possible. The common speed control circuits include throttling speed control circuit, volumetric speed control circuit, and volumetric throttling speed control circuit. The power loss of the throttling speed control circuit is large, and the low-speed stability is good. The volumetric speed control circuit has neither overflow loss nor throttling loss, with high efficiency, but poor low-speed stability. If both requirements need to be met simultaneously, a volume throttling speed control circuit consisting of a differential pressure variable pump and a throttle valve can be used, and the pressure difference between the two ends of the throttle valve should be minimized as much as possible to reduce pressure loss.
Fourth, choose hydraulic oil reasonably. When hydraulic oil flows in the pipeline, it will exhibit viscosity, and when the viscosity is too high, it will generate significant internal friction, causing the oil to heat up and increasing the resistance to oil flow. When the viscosity is too low, it is easy to cause leakage, which will reduce the system's volumetric efficiency. Therefore, it is generally recommended to choose oil with suitable viscosity and good viscosity temperature characteristics. In addition, when the oil flows in the pipeline, there are also pressure losses along the way and local pressure losses. Therefore, when designing the pipeline, try to shorten the pipeline as much as possible and reduce bends.
The above * * are several measures proposed to avoid power loss in hydraulic systems, but there are still many factors that affect power loss in hydraulic systems. Therefore, when designing a hydraulic system, it is necessary to consider other requirements comprehensively.
