Description

Oil feeder

Technical Field

The utility model belongs to the technical field of the lubricating oil technique is relevant, especially relate to an oil feeder.

Background

The lubricating oil is used in compressors such as piston compressors, sliding vane compressors, single-screw compressors, double-screw compressors and the like, and can play roles in lubrication, cooling, flushing, sealing, vibration reduction, unloading and protection. Specifically, lubrication: improving friction condition, reducing friction, preventing abrasion, and reducing power consumption. Cooling effect: most of the heat generated during friction is taken away by the lubricating oil, and a small part of the heat is directly radiated by conduction radiation. Washing action: the worn debris can be taken away by lubricating oil, so the flushing effect is called as flushing effect, the flushing effect has great influence on the abrasion, the lubricating oil formed between the friction surfaces is very thin, and the metal debris stays on the friction surfaces to damage the oil film to form dry friction, so that the abrasion of abrasive particles is caused. Sealing action: the sealing between the cylinder wall and the piston of the screw air compressor is realized by means of the sealing function of lubricating oil. Damping action: the friction piece moves on the oil film and plays a certain role in buffering the vibration of the equipment as if floating on an oil conservator. Unloading function: because of the existence of the oil film between the friction surfaces, the load acting on the friction surfaces is distributed on the friction surfaces relatively uniformly through the oil film, and the action of the oil film is called unloading action. Protection: the screw rod type air compressor can be prevented from corrosion and dust, and has a protection effect.

It follows that lubricating oil can play a very important role in the operation of the apparatus. However, in the process of long-term operation of the equipment, the temperature of the lubricating oil is increased due to mechanical friction, oil gas is generated after the temperature of the oil is increased, a part of the lubricating oil is taken away by the oil gas after long-term operation, the oil level of the lubricating oil is reduced, the lubricating oil needs to be supplemented in time when the oil level of the lubricating oil is reduced to the position below an oil level, so that the stable operation of the equipment is ensured, and equipment faults can be caused if the lubricating oil cannot be supplemented in time after long-term operation.
