Low Noise Air Compressors: Ensuring A Quiet Environment in The Chemical Fiber Industry

Two-stage permanent magnet frequency conversion air compressor is a kind of high-efficiency and energy-saving air compression equipment.
Working Principle
It adopts two-stage compression technology to gradually increase the gas pressure through two compression stages. In the first stage of compression, the air is initially compressed to a certain pressure, and then it enters the intermediate cooler for cooling to reduce the temperature before entering the second stage of compression to finally achieve the required high pressure output.
Permanent magnet frequency conversion technology, on the other hand, makes use of permanent magnet synchronous motors to automatically adjust the motor speed according to the actual air demand, thus achieving precise air volume control. Compared with the traditional fixed-frequency air compressor, it can effectively avoid frequent starting and stopping and no-load operation, which greatly reduces energy consumption.
Product features
High efficiency and energy saving: The combination of two-stage compression and permanent magnet frequency conversion technology makes the compressor able to save energy to the maximum extent during operation. Compared with single-stage compressor, two-stage compression can reduce energy consumption by about 15% to 30%. Meanwhile, the high efficiency of the permanent magnet synchronous motor further improves the overall energy efficiency.

The permanent magnet motor does not require excitation current, which reduces the loss and heat generation of the motor and prolongs the service life of the motor. Moreover, the intermediate cooling in the two-stage compression process can effectively reduce the temperature of compressed air and reduce the damage to the equipment.
Intelligent control: Equipped with intelligent control system, it can monitor the running status of the equipment in real time and adjust the parameters automatically to achieve unattended operation. Users can conveniently operate and manage the equipment through touch screen or remote control.
Low noise: optimised structural design and sound insulation measures make the air compressor run with low noise, providing users with a quiet working environment.

A heat exchanger is a highly efficient device for transferring heat between different media.
Principle of operation
The heat exchanger uses two or more fluids of different temperatures to transfer heat through a solid wall. The high-temperature fluid transfers heat to the wall, and the wall transfers heat to the low-temperature fluid, so that the low-temperature fluid is heated and the high-temperature fluid is cooled. According to the different ways of heat transfer, heat exchangers can be divided into three types: inter-wall, hybrid and thermal storage. Of these, the inter-wall heat exchanger is the most common type, which separates the two fluids by a solid wall, avoiding direct contact between the fluids.
