Misunderstanding of feed equipment during lubrication

2020-03-14 Back to List

The starting point of feed equipment lubrication is to ensure the normal operation of the equipment, reduce maintenance costs and extend the service life, but it is basically to improve the economic efficiency of the enterprise. Although this part of the lubrication cost only accounts for a small part of the maintenance costs and product costs, it has a great impact on the maintenance and production of the equipment. However, there are some misunderstandings when lubricating feed equipment:

1. The purpose of lubrication is to make the equipment run faster:

The purpose of lubrication is to give the equipment normal lubrication, so that the equipment does not cause malfunction during operation, so as to maintain the normal operation of the equipment, thereby improving productivity and economic benefits.

2. Lubrication is refueling:

When the equipment oiling, refueling, and inspection intervals are determined, operations and inspections should be performed according to the determined equipment refueling location, refueling cycle, refueling volume, refueling method, and lubricant used (requirements for key locations More, stricter), not once and for all.

3. The more the better, the better:

When a device is designed, its refueling quantity is strictly specified. The operator should replenish the lubricant according to the instructions and daily observation of the oil standard, sight glass, etc. If you add more fuel, it will have some side effects. For an air compressor, the crankcase is overfilled with oil, which increases the resistance of the crankshaft. In the reduction gearbox, in order to reduce the motion resistance of the gear and prevent the oil temperature from rising, the depth of the gear immersed in the oil is 1 to 2 teeth high. It is better to be shallower when the speed is high; it is also impossible to fill the bearing cavity completely when grease the rolling bearing, otherwise the running resistance of the bearing will be increased, it will be easy to generate heat, cause the oil temperature to rise, and the grease will run off, making the lubrication Defective or damaged bearings.

4. Oil can lubricate:

When designing a piece of equipment, the designer specifies the lubricating oil used by the equipment according to the mechanism, not all the lubricating oils can play a lubricating role. In order to make the equipment reasonably lubricated in different environments, a certain amount of additives are added to the lubricating oil. The additives added to each lubricating oil are different and the performances are different. Therefore, it is necessary to according to the equipment situation and the use environment. Selecting the right lubricant can achieve good lubrication effect.

5. Reuse of waste oil:

Some waste oil can be reused after the oil quality analysis of the equipment. For lubricating oil that has water in the oil, it can be dewatered by an oil-water separator; mechanical impurities and sludge in the lubricating oil can be removed by a filter. Especially after the equipment is damaged, due to the long procurement cycle of spare parts, the shutdown and production will be delayed for a long time, which will affect the completion of the production plan and seriously damage the business efficiency of the enterprise. Therefore, we give full play to the efficiency of mechanical equipment, improve the reliability of equipment use, Avoid lubrication mistakes.
