Abstract

The invention discloses a marine diesel-driven screw air compressor. The marine diesel-driven screw air compressor comprises a shell, an air inlet is formed in the side wall of the shell, a first air inlet pipe is arranged on the air inlet, a three-way air valve is arranged at the end of the first air inlet pipe, a second air inlet pipe and a third air inlet pipe are arranged at the other end of the three-way air valve, a cooling chamber is arranged at the other end of the second air inlet pipe, a condensation pipe is arranged in the cooling chamber and comprises an inner pipe and an outer pipe, cooling liquid flows in the inner pipe, the outer pipe is connected with the second air inlet pipe, a first cold air guide pipe is arranged on the cooling chamber, the first cold air guide pipe communicates with the other end of the outer pipe, a first drying chamber is arranged at the other end of the first cold air guide pipe, a second cold air guide pipe is arranged on the first drying chamber, a second drying chamber is arranged at the other end of the third air inlet pipe, an air guide pipe is arranged on the second drying chamber, a compression shell is arranged at the other end of the air guide pipe and the other end of the second cold air guide pipe, and a female rotor and a male rotor are arranged in the compression shell.

Description

technical field [0001] The invention belongs to the technical field of air compressors, in particular to a marine diesel-driven screw air compressor and a processing method thereof. Background technique [0002] According to the different internal structures of air compressors, air compressors currently on the market are mainly divided into screw air compressors, piston air compressors, centrifugal air compressors, etc. Centrifugal air compressors are mainly used in occasions with very large air consumption, and are rarely used in general enterprises. Piston air compressor equipment has low investment, and many enterprises have used it in the past, but the gas production efficiency is poor, and it is gradually being replaced by screw air compressors. [0003] For marine diesel-driven screw air compressors, when the air compressor starts, the pneumatic control system keeps the intake valve open, which means that the load on the compressor is relatively large when the compres...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned diesel screw air compressor is cooled by cooling water, but the temperature of the cooling water is too high or too low is not conducive to the operation of the diesel screw air compressor, and the temperature of the cooling water is not easy to control, once the temperature is high At 95°C, it is easy to accelerate the wear of the parts of the air compressor, and it will also affect the cooperation between the parts. Therefore, other heat dissipation is needed to match the heat dissipation of the cooling water, especially for the heat dissipation of the shell of the diesel-driven screw air compressor.
