First of all, on the whole, we should know that the piston air compressor is very noisy and inconvenient to maintain. Most piston compressors often have problems during use, which will bring users a lot of inconvenience. Screw air compressor can reduce the production cost of the factory, increase economic benefits, facilitate equipment management, improve the operating efficiency of the company, eliminate the existing piston air compressor with high efficiency and reliability screw air compressor, and rebuild an progressiveness and economical air energy station, which is an inevitable trend for the growing development of the existing factory enterprises.

contrast:

The old piston air compressor has poor economy and reliability. The piston air compressor is a model that many old users are very familiar with. In the early development period, it was a product that everyone agreed with. However, with the continuous innovation of technology and the emergence of new air compressors, the shortcomings of the piston air compressor are becoming more and more prominent, and the shortcomings are also growing compared with screw air compressors:

1. The piston air compressor has many vulnerable parts such as air valve, piston, piston ring, connecting rod bush, etc. The reliability of continuous operation is very poor. On the one hand, frequent maintenance will affect production, on the other hand, it will increase the cost of maintenance management.

2. Compared with screw air compressor, piston air compressor has low efficiency, especially for long-term continuous operation, its economy is worse. Because there are many wearing parts in the compression chamber of the piston air compressor, the wear and damage of these wearing parts will cause greater leakage during gas compression, which will eventually lead to the reduction of the exhaust efficiency of the air compressor. As there are no wearing parts that affect the machine efficiency in the screw air compressor, a pair of rotors for compression will not be easily worn due to their structural characteristics, so the economy of long-term continuous operation is far better than that of piston air compressor.

3. The piston air compressor is a reciprocating motion mechanism, which has an irreducible inertial force. Therefore, it has large vibration and high noise during operation. When installing a large piston air compressor, a special bottom fixed foundation should be built to avoid damage to the equipment caused by excessive shaking during operation. The screw air compressor is a rotary motion mechanism with good balance, low vibration, low noise, no need to install the foundation, and it can be installed and used at any time, avoiding excessive requirements for the working environment during installation, and effectively reducing the maintenance cost in the later period.

4. The piston air compressor supplies air intermittently to and fro. The intermittent pulsation of air flow is large during operation. The screw air compressor has high speed and stable gas transmission, which can ensure stable air flow pulsation and meet the needs of users with high and stable gas volume.

5. The piston air compressor basically has no automatic control system and can only be used whenever it is started. The screw air compressor has a perfect program automatic control and protection system, which is an electromechanical product, facilitating the maintenance and management of the equipment and minimizing the energy consumption.

6. Screw air compressor is a highly centralized product with an overall structure. It occupies a small area. Without the complicated pipeline system of piston air compressor, it can optimize the installation and maintenance of the air energy system of the enterprise’s overall production system.

Now in the air compressor industry, piston air compressors are gradually being phased out. High maintenance difficulty, high maintenance costs, few accessories, unstable continuous operation performance, high power consumption and loud noise are undeniable shortcomings of piston air compressors; The screw air compressor has entered the stable development period of the industry, and now it is rapidly developing towards higher and better performance and power conversion.
