HOT LINE: +86-510-80628100The various components of the hydraulic device in the hydraulic press are connected together through pipelines. The hydraulic pipelines transport hydraulic oil from the hydraulic pump to each actuator, and then return it to the oil tank from the actuator to form a closed circuit. Pipeline design is a key technical issue to ensure the quality of hydraulic presses. The main problems in the current pipeline design are as follows:
(1) Interference issue.
(2) The issue of whether the pipeline layout is reasonable.
(3) Distribution of working medium flow field inside the pipeline.
(4) Pipeline vibration and energy consumption issues.
(5) The issue of easy disassembly and assembly.
(6) Issues such as safety, reliability, and pipeline lifespan in the later stage.
In response to the above issues, the main research content of hydraulic press pipeline design includes the following points:
(1) Design of pipe diameter and wall thickness
The inner diameter of a pipeline is mainly related to the flow rate and velocity inside the pipeline. A too small inner diameter can cause excessive flow rate of the working medium, accelerate temperature rise, increase energy consumption, and easily lead to cavitation, causing problems such as pipeline leakage, vibration, and noise; Excessive inner diameter can cause an increase in the volume and mass of the tubing, as well as an increase in the weight and cost of the equipment. The wall thickness of the pipeline is related to the inner diameter, maximum working pressure, and allowable stress of the pipeline. Choosing too small a wall thickness will reduce the safety of the pipeline; Choosing too much can lead to an increase in equipment quality and cost.
(2) Flow field and temperature distribution of important pipe fittings
Elbows and tees are important components of pipelines. When fluid flows through elbows, the flow field inside the pipeline will undergo significant changes, causing pressure and velocity redistribution, resulting in energy loss and pipeline vibration. At the same time, when different inflow methods are used, the distribution of the three-way flow field and temperature field is also very different. Even at some key points in pipeline design, the flow field and temperature field distribution of the two will directly affect the direction and layout of the entire pipeline.
(3) Piping design and piping principles.
(4) Modal analysis and support arrangement of pipeline vibration
(5) Determination of pipeline design principles
Hydraulic pipeline design is the use of pipelines and various fittings to connect various components in hydraulic devices to achieve the functional design of hydraulic systems.
With the development of computer technology, the application of modern design methods in pipeline design mainly focuses on numerical analysis of pipeline design, pipeline layout, and pipeline vibration research.
When designing pipelines, advanced modeling and analysis software should be combined, recent research results should be absorbed, and a more systematic design method should be summarized to shorten the pipeline design cycle, increase efficiency, and improve reliability of hydraulic presses.
