Use of heat transfer oil rotary joint for non-woven equipment production line

1. The Non-woven equipment production line believes that the rotary joints currently on the market are all flat-sealed or spherical-sealed. Rotary joints with spherical seals mostly use line seals. This makes it easy for impurities or particles to enter the dynamic sealing surface. Rotary joints can easily leak when the equipment is turned. And heat transfer oil slagging is a headache problem. In order to prevent leakage of the heat transfer oil rotary joint and prolong the service life of the heat transfer oil rotary joint, the best way is to heat it first, and then turn it on after the temperature rises. This will soften the oil residue and prevent hard particles from damaging the dynamic sealing surface.

2. Generally, the difference between the shell temperature of the heat transfer oil rotary joint and the temperature of the heat transfer oil circulating inside is only 30℃-50℃. In order to prevent the casing from leaking and hurting people, the best way is to install a protective cover outside. That is to prevent people from touching the surface of the rotary joint of the heat transfer oil, and also to prevent the hot oil from scalding people and products when the rotary joint leaks.

3. The heat transfer oil rotary joint with spherical seal must be matched with a metal hose, and the rotary joint is better to be slightly fixed. Prevent the swivel joint from driving the metal hose to rotate, causing the metal hose to rupture. Rotary joints with spherical seals must not be fixed too tightly. Otherwise, the concentricity cannot be adjusted automatically. cause a leak. The use of flat-sealed rotary joints can eliminate the use of metal hoses and use hard pipes, but also pay attention to concentricity during installation. Prevent the swivel joint from being stressed on the pipe, causing the pipe to twist or the swivel joint to be damaged.

4. The non-woven equipment production line should pay attention to the positive and negative rotation of the heat transfer oil rotary joint connected by the wire teeth. The installation direction of the rotary joint must be opposite to the direction when the drum is working. Otherwise, it is easy to pull back the wire. Rotary joints connected by flanges should be screwed evenly to avoid concentricity deviation and loose installation. Cause leaks or pipe twists.
