1. Grasp and identify the basic knowledge of fake and shoddy products, and purchase high -quality and standardized polyurethane sealing oil sealing.
2. During installation, if the appearance of the shaft diameter is low or the shortcomings such as rust, rust, and wool edges, polish polishing and polishing with fine sand cloth or grinding stones; The matching site is coated with oil or lubricating fat. Polyurethane sealing oil seal is coated with a sealant outside the outside, wrap the body groove position on the shaft with a hard paper shell to prevent scratching polyurethane sealing oil sealing lips, and use common tools to turn the polyurethane sealing oil seal in it Do not smash hardness to prevent polyurethane sealing parts from changing or squeezing yellow and invalid; if the lip mouth is reverse, the spring falls down, and the polyurethane sealing oil seal is tilted, it must be removed and packed in again.
3. The general work of polyurethane sealing oil sealing on the mechanical equipment is generally standard, the temperature difference between the natural environment is large, the floating dust, and the machine vibration often causes the part to withstand the force to continue to change, maintain, maintain and maintain.
4. If the shaft diameter and rolling bearings are severely damaged; polyurethane sealing parts of the oil seal from the sulfurized rubber crispy or effective, etc., the corresponding components of maintenance and disassembly should be carried out immediately.
5. For the abnormal permanent components or the total program, it should be detected immediately; prevent the mechanical equipment from speeding and overloading to avoid rising the temperature of the oily lip of polyurethane sealing parts, the brittleness of vulcanized rubber, and the initial damage of the lip mouth.
6. It is necessary to check the amount of oil oil. If there are too many oil residues, the new machine oil should be completely disassembled when there are alloy powder and metal materials. The oil brand and quality of the replacement must meet the requirements of the season.
