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…

The purpose of any air compressor control system is to most efficiently match the demand and supply of compressed air. While old-fashioned electropneumatic controls are being replaced by microprocessor-based controls with optimized systems and software upgrades for control parameters, any type of control is either fixed-speed or variable-speed control.  …

  When disassembling bearings, sealing parts and lifting rotor, knocking and collision are strictly prohibited to prevent parts from being damaged.   Parts with the same shape should be numbered and grouped, and the matching parts should be marked and kept correspondingly to prevent wrong installation.   Complete sets of…

   Air compressors can be divided into low-pressure air compressors and high-pressure air compressors according to the level of pressure. Exhaust pressure refers to the highest pressure of the air compressor exhaust gas, generally expressed in bar or Mpa, 1bar=0.1 Mpa users often refer to the pressure unit as:…

Leakage: When the screw air compressor is running, there is a gap between the rotors and between the rotor and the casing, and no direct contact will cause gas leakage. When the gas pressure rises through the suction pipe gap and suction groove, it can reduce the air discharge. Therefore,…

The all-in-one cold dryer does not start ① Check whether the air dryer is correctly connected to the power supply. ②Check if the neutral line is missing. ③ Check whether the switch is malfunctioning. ④ Check whether the high and low voltage protectors have tripped for protection. ⑤ Check whether…

 The air compressor can only be started when the indoor temperature of the air compressor room is kept above 5°C.   Close the sliding door of the exhaust air outlet of the air compressor unit that is not open, and close the indoor hot air exhaust outlet to ensure…

Effects of air compressor vibration:   Cause failures such as cylinder pulling and tile burning.   Increase equipment power consumption and waste energy.   Make noise and affect the surrounding environment and workers.   Cause instrument failure and affect the stability of normal operation.   The wear of the frictional…
