The selection of rotary joints is a process that comprehensively considers multiple factors. The following are some key selection points and steps:
1) Media type:
Determine which fluid medium the rotary joint will be used to transmit, such as water, air, steam, thermal oil, hydraulic oil, etc. Different media have different requirements for the material, sealing method, and corrosion resistance of rotary joints.
2) Pressure and temperature:
Determine the maximum working pressure and temperature of the medium to ensure the long-term stable operation of the rotary joint.
3) Speed:
Consider the rotational speed of the equipment and choose a rotating joint that matches it. High speed rotating equipment requires the use of rotary joints with higher wear resistance and stability.
4) Number of pathways:
Choose the appropriate single channel, dual channel, or multi-channel rotary joint based on the type and quantity of media that the device needs to transmit. Multi channel rotary joints can simultaneously transmit multiple media, improving equipment efficiency.
1) Type selection:
Determine the type of rotary joint to be used based on the structure of the equipment connected to the rotary joint. For example, if the structure of the device determines that the input medium and output medium are implemented on the same side of the device, then a multi-path rotary joint must be selected; If implemented separately on both sides, choose a single rotary joint.
According to specific application scenarios, specific types of rotary joints such as hydraulic rotary joints, high-pressure rotary joints, and high-temperature rotary joints can also be selected.
2) Structural form:
Determine the connection method between the rotary joint and the equipment, such as threaded connection, flange connection, etc. The selection of connection method needs to consider factors such as device structure, installation space, and maintenance convenience.
Select the appropriate rotary joint based on the interface size and interface standards of the device, ensuring that the rotary joint matches the interface of the device.
1) Sealing performance:
The sealing form of a rotary joint directly affects its sealing performance and service life. Common sealing forms include ring seals, mechanical seals, and gap seals. The appropriate sealing form needs to be selected based on factors such as the properties of the medium, pressure, and temperature.
Choose a rotary joint with good sealing performance to prevent medium leakage and environmental pollution.
2) Wear resistance and corrosion resistance:
Rotary joints are subject to wear during use, so it is necessary to choose products with high wear resistance. A rotary joint with good wear resistance can extend its service life and reduce maintenance costs.
If the medium is corrosive, it is necessary to choose a rotary joint with corresponding corrosion resistance. The selection of corrosion resistance should be determined based on the chemical properties and concentration of the medium.
3) Brand and Quality:
Choosing well-known brands and high-quality products can ensure the performance and reliability of rotary joints. Before purchasing, it is important to carefully understand the brand, quality, and after-sales service of the product.
1) Installation convenience:
Choosing a rotary joint that is easy to install and maintain can reduce usage costs and improve equipment reliability. During the installation process, it is necessary to strictly follow the product manual to ensure correct and error free installation.
2) Maintenance convenience:
Rotary joints may experience wear or malfunction after prolonged use, therefore it is necessary to choose rotary joints that are easy to maintain and replace. At the same time, the wear of the rotary joint should be regularly checked, and severely worn components should be replaced in a timely manner.
In summary, the selection of rotary joints requires comprehensive consideration of multiple factors such as medium type, pressure and temperature, speed, number of channels, type and structure, performance and quality, as well as installation and maintenance. By making reasonable choices and using them correctly, it can be ensured that the rotary joint plays a good role in the equipment.
