During the use of the screw air compressor, sometimes there will be a failure of low pressure, so what is the reason for the low pressure of the screw air compressor? 1. The deflation valve is faulty (it cannot be closed when loading); 2. The pressure switch setting is too…

Introduction of air compressor accessories: Durable accessories include cylinder blocks, cylinder heads, seals, brakes, oil pumps, safety valves, etc., but screw air compressors are different from piston air compressors, and the working principle of screw air compressors is different from that of piston air compressors. , The design is different.…

 Under normal circumstances, the installation of frequency converters on ordinary screw air compressors will have the following disadvantages: 1. Ordinary screw air compressors use power frequency motors. After installing a frequency converter, the frequency adjustment range is only 25~50Hz, which basically cannot achieve energy saving effect, and can only…

1. The working environment of the air compressor should be kept clean and dry. The gas storage tank must be placed in a well-ventilated place, and sunlight exposure and high-temperature baking are strictly prohibited. 2. The installation of power wires for air compressors must comply with the requirements of safe…

The selection of the air compressor is mainly based on the working pressure and flow of the pneumatic system. The working pressure of the gas source should be about 20% higher than the maximum working pressure in the pneumatic system, because the along-course loss and local loss of the gas…

 Benefits for users: A． Equipment operation cost is low Since the oil-free machine only needs less spare parts consumption: no need to add and replace lubricating oil, no oil filter consumption, no oil removal filter to reduce oil content, no oil-air separator core (multi-stage) There is no need for…

Working principle of screw air compressor The compressed air system uses a twin-screw air compressor. The work of the machine is divided into three processes: intake, compression and exhaust: 1. Inhalation process: The motor drives the rotor. When the red groove space of the master and slave rotors turns to…

The use of air compressor 1. Compressed gas is used for refrigeration and gas separation: The gas is liquefied after being compressed, cooled, expanded, and used for artificial refrigeration (refrigeration and air conditioning, etc.) such as ammonia or Freon air compressors. The compression pressure is mostly 8-12 kg/cm2, and this…

 When choosing a good air compressor, pay attention to the following points: 1. The level of exhaust pressure and exhaust volume should be considered. According to the national standard, the exhaust pressure of the general-purpose air compressor for aerodynamics is 0.7MPa (7 atmospheres), and the old standard is 0.8MPa…

  Since the birth of the screw air compressor, the profile of the screw rotor has experienced many reforms. With the development of computer technology, people have been able to develop a variety of high-efficiency profiles that are currently recognized. Manufacturers of screw air compressors in the world can also…
