Abstract

The invention relates to a screw air compressor, and provides a low load starting screw air compressor. The low load starting screw air compressor comprises a shell body with a main cavity body and two screws which are arranged in the main cavity body and are mutually meshed, wherein the inner wall of the main cavity body has a plurality of by-pass holes; the shell body has an air inlet and an exhaust hole, each by-pass hole is positioned between the air inlet and the exhaust hole, and the shell body is also provided with an accessory cavity body communicated with each by-pass hole; the accessory cavity body is internally provided with a valve body for plugging each by-pass hole, and the shell body is provided with a driving mechanism which is used for driving the valve body to plug each by-pass hole and is driven to operate through a power device. The low load starting screw air compressor provided by the invention has the advantages that when the power device is started, the accessory cavity body of the air compressor and the main cavity body are communicated through the by-pass holes, partial air which is absorbed into the main cavity body flows to the accessory cavity body through the by-pass holes, the starting load of the power device is reduced, the power device and the air compressor can normally start under the low-temperature environment, the power device controls the valve body to plug the by-pass holes after normal starting, and the normal operation of the air compressor is guaranteed.

Description

technical field [0001] The invention relates to a screw compressor, in particular to a low-load start-up screw air compressor. Background technique [0002] Screw air compressor has the advantages of high efficiency, high efficiency, maintenance-free and high reliability, etc. It can provide high-quality compressed air to all walks of life. When the screw air compressor is working, during the relative meshing rotation of the twin screws, the volume between the two teeth changes from small to large, and then from large to small, so that the air compressor continuously sucks in air from the air inlet first. , and then continuously compress the air inhaled by the air inlet, and finally discharge it completely from the air outlet. [0003] Generally, a screw-type air compressor is provided with a screw valve for adjusting the volumetric flow rate of the air compressor. The inner wall of the air compressor is provided with a number of bypass ports for discharging air. The screw ...
