Abstract

The invention discloses a permanent magnet frequency conversion screw air compressor, and relates to the technical field of air compressor accessory devices. The problem that a motor in the compressor is difficult to maintain and disassemble is solved. The air compressor specifically comprises a shell, box bodies are fixedly installed on the two sides of the shell through bolts, sliding rails are fixedly installed at the front ends and the rear ends of the sides, not adjacent to each other, of the inner walls of the two box bodies through screws, fixing blocks are fixedly installed on the sides between the sliding rails, and the two fixing blocks on the same side are provided with the same first arc plate; and inserting columns are fixedly mounted at the front end and the rear end of the top of one side between the two first arc plates in a welding manner. The first arc plate, the second arc plate, the third arc plate and the like are arranged, the first arc plate, the second arc plate and the third arc plate are sequentially pulled out, the effect of covering the top of the shell is achieved; the first arc plate, the second arc plate and the third arc plate are contained in the box body during maintenance, and the motor is exposed outside, so that maintenance and detection are facilitated, and the maintenance time is shortened.

Description

technical field [0001] The present invention relates to the technical field of air compressor accessories, in particular to a permanent magnet variable frequency screw air compressor. Background technique [0002] The permanent magnet variable frequency screw compressor is an air compressor that can change the power supply frequency, adjust the load, and reduce power consumption. The core is the frequency converter, which can adjust the operating speed of the motor through the conversion of the power supply frequency. Ordinary variable frequency air compressor: equipped with traditional asynchronous different magnetic motor, and permanent magnet variable frequency screw compressor has the advantage of configuring "rare earth permanent magnet motor" compared with ordinary variable frequency air compressor. [0003] The existing permanent magnet frequency conversion screw machine motor is generally fixed on the inner bottom of the shell by multiple bolts. This method causes a...
