The simplest point is to see whether it contains a frequency converter, and the second is to see whether the motor changes its speed according to the actual working conditions during operation.
There are nameplates on the air compressor. You can see the nameplates.
Look at the rated speed on the nameplate of the motor.
The three-phase AC permanent magnet variable frequency motor is a synchronous motor.
Ordinary is a three-phase AC asynchronous motor, there is a certain slip rate.
Cold dryer is a type of air dryer. The air dryer is a broad concept that covers all equipment used to remove moisture from the air. These devices achieve the purpose of air drying through different working principles and technical means to meet the needs of various industrial and
Usually screw compressors need to be maintained after more than 2000 hours of operation. Air compressor oil is an essential part of the maintenance process, while air compressor oil has poor quality, many impurities and high viscosity. Easy to cause, air compressor oil shortage. The bearing shell is displaced so that
The calculation of equipment gas consumption (converted into cubic meters) should be combined with equipment parameters, operation time and gas state (such as pressure and temperature). The following are detailed steps and examples: 1. the core formula Volume flow calculation If the equipment is known to be in the standard state (0°C,1 atm)
Q: Do oil-free air compressors really not need oil? Why. The "water lubricated air compressor" series of oil-free air compressors commonly used in China are used more frequently. When the air compressor head works, there is no lubricating oil, but water is used to moisten it.
The oil-free variable frequency screw air compressor has many advantages, including energy saving, environmental protection, stable operation, low noise, low maintenance cost, and long service life. The following is a specific introduction: energy saving: oil-free frequency conversion screw air compressor adopts advanced frequency conversion technology, which can be based on
Insufficient air supply of air compressor may be caused by a variety of reasons, the following are some possible reasons: maintenance is not timely: when the operating environment of the unit is not ideal, check whether the air filter and oil filter are blocked. If the exhaust volume decreases due to clogging of the air filter and oil filter, only
Compressed air standards for industrial use focus on its cleanliness, dryness, pressure stability and other core indicators, these standards are designed to ensure the safety, stability and product quality of compressed air in various industrial applications. The following from the quality indicators, the industry should be
When the content of water in the air is expressed in ppm (parts per million), it is not a fixed value, but is affected by many factors such as temperature, humidity, geographical location and climatic conditions. It is usually several hundred to several thousand at normal temperature and pressure. Between ppm. specify the influencing factors in the air
The replacement cycle of air compressor oil is not fixed. It is affected by many factors, including oil type, model, working environment and frequency of use. Here are some general guidelines: Mineral oil: It is generally recommended to replace after 3 to 4 months of use
Judging from the oil content, oil-free and oil-free in the air compressor generally refer to the oil content of the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil compressor is relatively large, and the oil content of the oil-free oil compressor is 0.01ppm. Therefore, this oil content is used to distinguish oil-free and oil-free in the air compressor.
