What Is a Diesel Compressor?
Screw compressors [1] are divided into single-screw compressors and twin-screw compressors, which were first proposed by the German H. Krigar in 1878. It was not until 1934 that the Royal Institute of Technology A. Lysholm laid the technology and began to be used in Application and achieved rapid development.
- Screw compressor [1]
- Oil-free screw compressor
- The first in the world in 1956
- The introduction of the twin-screw host, the working process: the inter-tooth elementary volume (that is, the working volume formed by each pair of teeth) gradually expands as the rotor rotates, and communicates with the air inlet orifice at the bottom left of the machine, and the gas enters through the orifice Primitive volume
- First, before the start of the operation
- 1. Check to make sure that the valves in each part are in the correct position.
- 2. Check that all protective devices and safety accessories are in good condition.
- 3 Check that the lubricating oil surface is up to standard.
- Operation steps
- 1. First press
- Screw compressors consist of a pair of parallel, intermeshing female and male screws.
- Screw rotor profile in screw compressors [2]
- Daily maintenance matters
- 1.Check for empty
- 1. Screw air compressor: mainly used for
- Screw compressors have the characteristics of small size, light weight, and easy maintenance. They are one of the fastest-growing models in refrigeration compressors. On the one hand, great progress has been made in the design of screw profiles and structures. On the other hand, the introduction of a screw rotor special milling machine, especially a grinding machine, has improved the processing accuracy and efficiency of the key parts, and has effectively improved the performance of the screw compressor. At present, screw compressors are mainly used in compressed air and medium-sized refrigeration heat pump air conditioning systems. Due to the continuous improvement of the reliability of screw compressors, it has gradually replaced reciprocating compressors in the medium cooling capacity range, and has occupied some markets of centrifugal compressors [3] .
