Description

Technical Field

[0001] The utility model relates to the technical field of screw air compressor buffering, in particular to a buffering device for a screw air compressor. Background Art

[0002] The screw air compressor is an oil-injected single-stage twin-screw compressor, which is divided into single-screw air compressor and twin-screw air compressor. It generally adopts high-efficiency pulley transmission to drive the main engine to rotate for air compression. The compressed air in the main engine is cooled by oil injection. The air and oil mixed gas discharged by the main engine is separated through coarse and fine separation to separate the oil in the compressed air, and finally obtain clean compressed air.

[0003] According to the description of a screw air compressor buffer device disclosed in the patent website (authorization announcement number: CN215058150U), "The utility model discloses a screw air compressor buffer device, including a screw air compressor body, and a stabilizing pressure plate is fixedly connected to the bottom of the screw air compressor body. The screw air compressor buffer device drives the sliding sleeve to buffer displacement on the control rod through the angle change of the swinging diagonal support plates on both sides, and at the same time uses the elastic force of the natural spring to buffer the force of its vibration, and then through the rotation of the control rod, the threaded displacement principle of the threaded cylinder and the control rod is used to drive the horizontal displacement of the push cylinder, and limit the horizontal sliding buffer displacement of the sliding sleeve, so that it is expected to ensure the reasonable buffer displacement of the screw air compressor body in the vertical direction, and at the same time, through the threaded displacement principle of the thrust pressure plate and the control rod, the compressed length of the natural spring is regulated, so as to more reasonably control the vibration force generated by the screw air compressor body after being subjected to the vibration force, and to reduce the consumption."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model uses the principle of threaded displacement of the thrust plate and the control rod to squeeze the natural spring outward to adjust the length of the compressed natural spring. However, in actual use, the sliding sleeve cannot be limited. Therefore, when the screw air compressor body needs to be disassembled or repaired, the stabilizing plate will still shake up and down, which makes it inconvenient to disassemble and repair the screw air compressor body. This has certain limitations. Therefore, it is necessary to improve a buffer device for the screw air compressor to solve the above problem. Utility Model Content
