How to Select the Proper Cooling Method for Air Compressors According to Actual Working Conditions?
When purchasing an air compressor for a factory, choosing the right cooling method is critical to stable operation, energy consumption and maintenance cost. There are two mainstream types: air cooling and water cooling. You can make judgment from the following practical dimensions. First, check t...Read more -
How to Select the Right Air Compressor Host for Factory Procurement？
The air compressor host is the heart of the whole unit. Its quality directly determines energy consumption, noise level, service life and later‑stage maintenance cost. Many factories only focus on the motor or total price during procurement while ignoring host selection. This may later cause seve...Read more -
Scenarios Suitable and Unsuitable for Permanent‑Magnet Variable‑Frequency Air Compressors
Summary: The core advantages of permanent magnet VSD air compressors are on‑demand air supply, high efficiency under variable load, stable pressure output, and zero idle power loss. Energy saving of 20%–35% can only be achieved under matching working conditions. Improper application will result ...Read more -
Working Principle of Permanent‑Magnet Variable‑Frequency Air Compressor？
A permanent‑magnet variable‑frequency air compressor mainly consists of three key parts: permanent‑magnet synchronous motor, variable‑frequency drive (VFD), and screw air‑end. Permanent‑magnet synchronous motor: Permanent‑magnet steel is embedded in the rotor. It does not need excitation current....Read more -
How to Judge Whether an Air Compressor Is in Long‑Term “Over‑Sized Operation”
“Over‑sized operation” means the rated air displacement of compressor is much higher than actual site air consumption. The unit runs under long‑term low load, resulting in energy waste, frequent load‑unload cycles and shortened service life. Even VSD compressors will lose most energy‑saving advan...Read more -
Will Piston Air Compressors Be Phased Out by Screw Compressors?
Overall, piston air compressors will not disappear completely. However, screw compressors are replacing them in most mainstream continuous‑operation industrial applications. The two types coexist with differentiated positioning rather than one totally eliminating the other. Benefiting from stable...Read more -
How to Clean Air Compressor Oil Cooler
1. Safety Preparation Before Cleaning Shut down the unit and cut off power with warning tag. Cool oil temperature below 60℃ to avoid scalding by hot oil. Release internal system pressure fully until pressure gauge reads zero. Remove outer protective covers to fully expose radiator fins. Clear...Read more -
How to Prevent Air Compressor Oil Emulsification
The root cause of oil emulsification is condensed water trapped inside the system that fails to evaporate or drain out completely and mixes continuously with lubricant. Water mainly comes from condensed intake moisture, dew formed after shutdown, and unevaporated liquid water under low temperatu...Read more -
Hazards Caused by Emulsified Air Compressor Oil
Oil emulsification means excessive water mixes into lubricant and destroys the original additive formula, completely disabling the oil’s functions of lubrication, heat dissipation, rust prevention and gas-oil separation. Minor cases lead to fast scrapping of consumables, while severe cases cause...Read more
