Bolaite BLT-100A S PM++ Oil-cooled Permanent Magnet Variable-frequency Air Compressor Helps Automotive Intelligent Parts Industry

In 2021, with the gradual control of the epidemic, China's automobile sales have returned to the positive growth track. With the development of intelligent connected technology and mobile Internet, the demand for customized intelligent experience in vehicles is gradually increasing, and intelligent auto parts are increasingly widely used.

A large automobile intelligent spare parts manufacturer in Jiangsu, a listed company limited by shares, is mainly engaged in the manufacturing of automobile intelligent accessories such as automobile intelligent seats and automobile shock absorbers. Due to the aging of the original air compressor and the increase of production capacity and gas demand, it decided to purchase one 75kW model.

There is one air compressor of other brands running in the factory of the enterprise, which was purchased earlier. The whole machine runs under full load for a long time, and an external frequency converter is adopted. The frequency conversion range is narrow, and the conditions of the air compressor room are poor. Initially, the customer preferred the product scheme of double-section compression air compressor (also known as double-stage compression air compressor in the market).

Bolaite recommended BLT-100A S PM++ oil-cooled permanent magnet variable-frequency air compressor, which is equipped with the new Atlas Copco high-efficiency main machine, and IP66 totally enclosed protection, IE4 high-efficiency oil-cooled permanent magnet motor and double frequency conversion system, and is superior to the national Level-1 energy efficiency. While ensuring high energy efficiency, it can easily cope with harsh working conditions. In addition, there are no common problems of double-section compression products for this model.

Although double-section compression can reduce internal leakage and intake air temperature to a certain extent, the internal structure of the compressor tends to be complex. The complex structure of main machine increases its size and weight, so the mechanical loss increases accordingly. In addition, with the increase of gas channels, the internal pressure loss will also increase. The above factors will offset the energy consumption dividend caused by the reduction of internal leakage. The complex main machine structure of double-section compression has more parts and components than the single-stage compression main machine, and there is more risk of failure.

See the figure above: The common double-section compression air compressor can only reduce the intake air temperature of the second stage by a few degrees through additional oil injection and cooling between stages, but this is only a variable compression process with slightly improved efficiency, with limited efficiency benefits, which can be offset by optimization of single-stage screw design and processing.

The customer was pleased to accept our scheme, and said that they did not care about single-stage compression or double-section compression in fact. The key is the improvement of energy efficiency and the stability of complete machine products.

Our professionalism to customers is the biggest help to our customers, so as to solve problems and make reasonable choices for customers.
