Oil Selection and Use Precautions for the Operation of the Spiral Duct Machine

Ⅰ. Oil selection for mechanical operation of spiral duct

The spiral air duct is a thin-walled pipe made of a spiral bite made of metal strips. It is round, without welding, air leakage, and water leakage. It is mostly used for air supply and bulk material transportation, instead of traditional white iron pipes (ie manual Bite iron pipe). The following are the precautions for oiling the spiral duct machine:

1. Proofread and check the pressure gauge every six months;

2. If the spiral duct machine is out of use for a long time, the exterior should be wiped clean and coated with anti-rust oil;

3. The working oil of the spiral duct machine adopts No. 46 anti-wear hydraulic oil, and the oil temperature is in the range of 15 to 60 degrees Celsius;

4. The oil should be carefully filtered before it is allowed to be added to the fuel tank;

5. The operating oil should be replaced once a year, and the replacement time should not exceed three months;

6. The slider should always be filled with lubricating oil, the outer surface of the column should be kept clean, and oil should be sprayed before each operation.

Ⅱ. Precautions for the use of spiral duct machinery

1. The principle of average force of each pass of the spiral duct machine, the average force of the entire line of rollers, the wear is balanced, and the service life of the rollers is prolonged.

2. The arc part of the track of the spiral duct cutter is the core part of the slide rail. The arc position after the first few passes is pressed and formed. When the vertical edge is rolled and folded in the subsequent passes, the formed arc should be passed through the upper and lower rollers or the horizontal wheel. Carry out effective tube bundle protection, otherwise, the arc position of the material will change during the stretching process.

3. The rolling stability of the spiral duct machine is often encountered in the production of the material swaying left and right in the raceway. In fact, the force of a single set of rollers is asymmetrical, the force on the left is large, and the material sways to the right; the right When the force is large, the material sways to the left.
