Open Type Ammonia Refrigerant Screw Compressor

Structural characteristics

• Rotor structure: It consists of a male rotor (usually with convex teeth) and a female rotor (usually with concave teeth), which mesh with each other and rotate inside the body to achieve gas compression.

• Drive mode: The compressor and motor are separated and connected through components such as couplings and pulleys. The motor can be configured separately according to requirements.

Sealing device: A sealing structure, such as mechanical seal or packing seal, is installed at the part where the shaft extends out of the body to prevent refrigerant or compressed gas leakage.

Working principle

Gas enters the compressor from the suction port, and as the rotor rotates, the volume between teeth gradually decreases, compressing the gas and increasing the pressure.

The compressed gas is discharged from the exhaust port and transported to the subsequent system through pipelines.

Applicable scenarios

Commonly used in large-scale refrigeration systems, industrial gas compression, and other fields, such as cold storage, central air conditioning, and gas compression in chemical production.

Due to its relatively open structure, it is easy to maintain and repair, making it suitable for situations with high maintenance requirements or frequent replacement of components.

advantages and disadvantages

• Advantages:

The structure is simple and easy to maintain, and the compressor or motor can be inspected and replaced separately.

The motor configuration is flexible, and suitable motor power and type can be selected according to different working conditions.

Suitable for various refrigerants and gases, with strong adaptability.

• Disadvantages:

There is a risk of leakage at the sealing area, and regular inspection and replacement of the sealing components are required.

The overall footprint is relatively large, and due to the presence of driving components, transmission efficiency may be affected to some extent.
