Abstract

he invention discloses a screw type inflator, comprising a screw type compressor host, an oil cooler, a cabinet equipped with an air intake and an air outlet and sound absorbing material arranged in the cabinet inner wall. The cabinet is provided with a main chamber and an auxiliary chamber, which are divided by an interlayer; the screw type compressor host is arranged in the main chamber of the cabinet; a lower part of the interlayer is provided with a main chamber air intake right opposite to a driving motor of the screw type compressor host; an upper part of the interlayer is provided with a main chamber air outlet, which is equipped with the oil cooler; the cabinet air outlet is arranged on an end face box wall of the auxiliary chamber; the cabinet air inlet is arranged on an upper part of a side surface box wall of the auxiliary chamber; the cabinet auxiliary chamber is provided with an auxiliary chamber interlayer, which divides interior of the auxiliary chamber into an air inlet channel and an air outlet channel. The invention solves problems of an existing screw type inflator, such as large noise and low whole machine working performance caused by negative air pressure in the cabinet.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a screw air compressor equipped with an external case. Background technique [0002] The vibration noise generated by the main engine of the screw air compressor and the vibration and airflow noise generated by the cooling fan are very loud. The sound intensity of this noise is sometimes as high as 90 decibels, which is unbearable for some working and living environments. In order to reduce the noise intensity when it works. The existing technical scheme is to add a cabinet outside the screw air compressor, and an air inlet is provided at the side wall of the cabinet facing the cooling air inlet of the driving motor of the screw air compressor, and an air inlet is provided on the top surface side of the cabinet. The wall is provided with a cooling air outlet, and the oil cooler of the screw air compressor is installed in the outlet of the cooling air in the cab...
