Breathing air compressors believe that everyone must be familiar with it. It is used in fire protection, industrial, diving, warship, military and first aid. The fully automatic, high-flow air breathing compressor is very popular in various fields. . After using the breathing air compressor for a period of time, we need to add lubricant to each part of the compressor for maintenance. The lubricant not only lubricates the friction surface, but also reduces friction and wear between the parts. So everyone knows how to breathe air compressors into the lubricant? The following small series introduces you to several ways to inject lubricants. Let's take a look!

(1) Breathing air compressor splash lubrication. Generally used for single-acting compressors without crossheads. The lubricating oil relies on the oil scoop provided on the large end cap of the connecting rod to splash the lubricating oil when the crankshaft rotates, and the oil mist and oil droplets fly to those places where lubrication is required. The first stage of the low pressure generates a negative pressure in the cylinder during the suction process. Therefore, the splashed oil mist or oil droplet is easily sucked into the cylinder and volatilized under the high temperature of the compressed gas, and then discharged together with the compressed gas. machine. Therefore, splash lubrication is often prone to excessive fuel consumption. The advantage of splash lubrication is that the structure is simple, and the disadvantage is that the fuel consumption is difficult to control.

(2) Breathing air compressor pressure lubrication. Pressure lubrication is mostly used in cross-head compressors and is the most widely used lubrication method. The lubricating oil is injected into the cylinder by a special plunger pump. Although the structure is complicated, the oil filling point and the oil filling amount are controllable and reliable.

(3) Spray lubrication. This is where a certain amount of lubricating oil and gas are mixed into the cylinder at the cylinder intake nozzle, a part is adhered to the cylinder mirror for lubrication, and the rest is discharged out of the cylinder along with the gas. In addition, due to the mixing of oil and gas, it is extremely easy to oxidize and deposit carbon. Although the spray lubrication structure is simple, the application is rare.

The above is the method of injecting lubricating oil into the breathing air compressor. You still need to know about it. If you encounter such a problem in the future, you can solve a lot of troubles.
