Pneumatic Hydraulic / Gas-liquid rotary joint

The gas-liquid rotary joint is a transitional sealing device connecting the gas or liquid medium input from the static system to the dynamic rotating system.

Use media: air, compressed air, liquid, oil

Maximum speed: 1200 rpm

Maximum temperature: 80 degrees

Maximum pressure: 2.0 MPa

Structural characteristics:

Pneumatic rotary joint is a series of products specially designed for pneumatic control. It has the advantages of small size, light weight and small friction torque. It adopts balanced seal. The friction group chooses different pairs of impregnated graphite, bronze, tungsten carbide and silicon nitride to resist the influence of impurities such as rust, scaling and debris on the sealing surface. Our seal is based on the balanced seal and the different pairs of impregnated graphite, bronze, tungsten carbide and silicon nitride. The parts are finished on CNC machine tools and special grinders. The surface is like a mirror, which makes the seal more reliable.

Applications:

Pneumatic Hydraulic rotary joint is mainly used in metallurgical machinery, rolling machinery, paper machinery, construction machinery and many other industries.

Required parameters for ordering rotary joints:

1. Provide working parameters of rotary joint: speed, pressure and temperature.

2. Dimensions of rotary joints

3. Connection mode, flange connection and threaded connection

4. Thread size: M5, G1/8, G1/4, G3/8, G1/2, G3/4, G1

5. Number of pathways (1 in 1 out 1 pathway, 2 in 2 out 2 pathway)

6. Whether to equip with conductive slip rings, provide the number of circuits, current magnitude, whether the signal needs to be shielded.

7. Are there any requirements for the torque of rotary joints?

8. Whether there is a requirement for manufacturing materials, optional: stainless steel, aluminium alloy, 45 # steel, engineering plastics

Circulation Category:

1. One-way flow mode: install rotating joint at both ends of the drum, the fluid enters from one end and discharges from the other end without using inner tube.

2. One-way flow mode: a rotating joint is installed at one end of the drum, and the fluid is introduced and discharged at the same time. The rotation of the inner tube relative to the drum is static.

3. Two-way flow (internal tube fixation): Different from the previous one, there are different siphons in the drum, which discharge condensate. This type is mostly used for steam type.

4. Two-way flow (inner tube rotation): This type is used for the structure where the inner tube is relatively fixed together with the drum and runs synchronously with the drum. At this time, the fluid is introduced by the inner tube and discharged by the outer tube.

5. Two-way flow (inner tube rotation): A siphon running synchronously with the drum is installed inside the drum, and condensate is discharged. This type is mostly used for steam type.

FAQ:
