Description

A new type of two-stage air compressor

technical field

The utility model relates to an air compressor, in particular to a novel two-stage air compressor.

Background technique

The technology and performance levels of compressors are constantly changing. There are many types of compressors. According to different working principles, compressors can be divided into fixed-displacement compressors and variable-displacement compressors.

However, most common air compressors on the market use single-stage compression, but the pressure produced by the first-stage compression is relatively high, and the volumetric efficiency is relatively low. Since all the power is borne by a pair of rotors, the service life of the single-stage compressor Shorter, its wear is greater. Can not meet the needs and development of energy-saving products, for this reason, we propose a new type of two-stage air compressor.

Compared with the prior art, the utility model has the following beneficial effects:

1. This new type of two-stage air compressor, after the air is removed by the air filter, the air enters the body of the screw host through the intake valve for compression, and through the added primary host and secondary host, the side wall of the screw host The middle bracket is fixed to the side wall of the permanent magnet motor, and the screw host is connected to the permanent magnet motor through a coupling, and then the permanent magnet motor is used to provide power to the screw host, which can effectively increase the efficiency of air compression.

2. The compressed air is mixed with lubricating oil, and the compressed air mixed with oil is discharged into the oil-air separator, and after the oil is removed by the oil-air separator and oil filter, the pure air is detected by the pressure sensor connected by the pressure maintenance valve , and the air pressure is stabilized at a certain value through the pressure maintaining valve. After the stable air pressure enters the cooler, the gas cooled by the fan is supplied to the user.

3. At the same time, the compressed oil-gas mixture is discharged into the oil-gas separator through the body of the screw main body. After the lubricating oil is separated from the gas, under the action of pressure, it enters the cooler and is cooled by a fan, then flows through the oil filter and is sprayed into the The main body of the screw main body cools the main machine, thereby avoiding the overheating of the main screw main unit and causing accidents.

4. After the controller detects the change of the user's pressure through the pressure sensor, it judges whether it needs to be loaded or unloaded by comparing the internal set value, and controls the intake valve in time to ensure that the user's gas pressure meets the requirements of use, thereby improving the safety of later use. More practical.
