What are the commonly used hydraulic pipes and joints?
Release time:
2022-07-20 16:22
All components and accessories of the hydraulic system are connected by hydraulic pipes and pipe joints, which transport the hydraulic oil from the hydraulic pump to each actuator, and then lead it back to the oil tank from the actuator to form a closed circuit.
1. Parameters and materials of hydraulic pipelines
1. Hydraulic pipeline parameters
the inside diameter of
The inner diameter and flow rate of the pipe determine the flow rate of the liquid in the pipe: the smaller the inner diameter and the larger the flow rate, the higher the flow rate and the larger the pressure loss.
Generally, the inner diameter of the pipeline can be selected according to the working pressure and flow rate. The flow rate in the pipeline with high pressure can be higher, that is, the inner diameter of the pipeline can be smaller. Designers can decide on a case-by-case basis. Follow the public account "Hydraulic Talk" to get more hydraulic knowledge.
Pressure resistance
The pipeline not only needs to withstand the steady-state pressure during operation, but also withstand dynamic shocks. Therefore, the pressure resistance of the pipeline must have a considerable safety system. Under normal circumstances, the minimum burst pressure should be more than 4 times the steady-state working pressure.
2. Classification of hydraulic pipelines
1. Hard tube
Steel pipe: It can withstand high pressure, the oil is not easily oxidized, and the price is low, but it is difficult to assemble and bend. Commonly used are No. 10 and No. 15 cold-drawn seamless steel pipes and stainless steel pipes, which are mainly used in medium and high pressure systems.
Copper tube: easy to bend when assembled, smooth inner wall, small frictional resistance, but low pressure resistance and poor vibration resistance. Generally used when it is lower than 6MPa. The price is more expensive, and it is easy to oxidize the oil in contact with the oil, so try not to use it as much as possible. Generally, it is only used as a small-diameter oil pipe for instrumentation and control devices.
2. Rubber hose
Generally used for the connection between parts with relative motion. The oil-resistant rubber clip is made of 1-3 layers of steel wire braided mesh or steel wire winding layer, which is easy to assemble and can absorb the shock and vibration of the hydraulic system. but less rigid
2. Commonly used pipe joints
Pipe joints are used for the connection between oil pipes and oil pipes, oil pipes and hydraulic components. The main functions are: to fix the pipeline; to be able to deform properly to compensate for the positioning error of the hydraulic components; to keep the seal even when the pipeline has a certain vibration.
A pipe joint consists of two parts: one part is connected to the pipe and the other part is connected to other components or pipes. The two parts are then screwed together. How do pipe joints connect to bare pipes? Follow the public account "Hydraulic Talk" to get more hydraulic knowledge.
1. Hard pipe connection
a) Flaring type: It is suitable for the connection of copper pipes or thin-walled steel pipes, and can also be used to connect nylon pipes and plastic pipes. It is widely used in the hydraulic system of general machine tools with low pressure.
b) ferrule type: when tightening the nut of the pipe joint, the tapered surfaces at both ends of the jacket are used to elastically deform the jacket to clamp the oil pipe. This kind of pipe joint is easy to assemble and disassemble, and is suitable for the connection of steel pipes in high-pressure systems, but it has high requirements on the manufacturing process and strict requirements on oil pipes.
c) Welded type: used to connect steel pipes with thicker walls and used in hydraulic transmission systems with high pressure.
d) Flange type:
2. Hose connection
The shape requirements of the connection part of the joints used with different hoses may be different, and you need to pay attention to the regulations of the hose supplier.
