Maintenance procedures for self-adjusting pipe rollers

1. Check and remove the obstacles on the machine before welding and use and keep it by special personnel. Do not touch the oil and fire when the self-adjusting pipe rollers are connected and frequently fill the oil holes.
2. Rolling bearings: Lubricate through the oil cap on the bearing cover. Sodium-based grease is recommended.
3. Transmission gear: For the first use, you need to remove the gear shield that is added actively, and apply a proper amount of grease. Sodium-based grease is recommended. During use, lubricating grease can be filled through the oil filling hole on the gear cover, and foreign matter is strictly prohibited from falling into the gear.
4. Cycloidal pinwheel reducer: Please add grease as required before use. Grease-2#, molybdenum disulfide-2#, or 2L-23 lithium-based grease is recommended at room temperature. The amount of grease loaded is 1/2-1/3 of the volume of the reducer. It is not advisable to add too much grease; otherwise, it will generate heat of stirring. The reducer should be replaced for the first time after 300 disappeared during the first operation. When replacing, the remaining dirty oil should be removed. Replace it every 6 months after that.
5. To ensure the equipment's performance, all transmission parts should be checked for lubrication regularly and irregularly. The cycloid reducer must be checked monthly to make up for lubricating oil.
6. All transmission parts are not lubricated and are strictly prohibited from using.
7. Before restarting the equipment that has been sealed for a long time, the grease must be replaced.
8. During use, the roller should fully contact the workpiece. It is strictly forbidden for the welding seam or sharp parts to touch the roller to avoid damage to the roller.
9. When hoisting and placing the workpiece, it is strictly forbidden to vigorously hit the roller to prevent damage to the roller or other parts. When the device is not fixed, a strong impact may cause the device to overturn.
10. When the roller frame is used for a small diameter cylinder, if the cylinder moves axially, adjust the adjusting bolt under the arc plate to adjust the roller lifting position (within a certain range) to ensure the cylinder The working position is in the best condition.

How to clean the exterior of the self-adjusting pipe rollers?

Stainless steel pressure vessel as a special vessel. Its manufacturing should have an independent and dedicated site and should be strictly isolated from carbon steel products. If the stainless steel pressure vessel is attached to carbon steel parts, the manufacturing site of the carbon steel parts shall be separated from the stainless steel. To prevent the pollution of iron ions and other harmful impurities, the production site of stainless steel pressure vessels must be kept clean and dry, and the ground should be covered with rubber or wood floors. The stacking of semi-finished parts and finished products must be equipped with wooden stacking racks.
