Screw air compressor installation precautions

Posted on

The air compressor is installed on a firm ground and the equipment foundation is cast in C20 concrete. Two axial fans are installed at the 016m elevation of each air compressor inlet grille of the air compressor plant. The air flow rate of the air intake grille does not exceed 015m/s, and the design of the intake axial fan is designed. The ventilation is consistent with the air volume of the compressor fan, ensuring the smoothness of the ventilation system.
Screw air compressor installation precautions
In order to ensure that the pressure drop of the air in the cooling air duct does not exceed 30Pa, it is necessary to ensure that the cross-sectional area of ​​the exhaust duct from the outlet of the air compressor is 2 to 3 times the cross-sectional area of ​​the top of the air compressor. And this ventilation duct is not necked. For other models of screw air compressors, such as the pressure drop of the air in the cooling air duct exceeds 30Pa, a ventilation fan should be installed at the outlet of the cooling air duct to ensure that the compressor outlet temperature is controlled within the normal range.
According to the air supply requirements of the device, the design loading pressure is 612 Bar and the load shedding pressure is 8 Bar. From the time of commissioning to the current operating conditions, this setting can ensure the normal operation of the device, especially to meet the instrument wind requirements of the cryogenic device.
The temperature of the compressed air before passing through the aftercooler should be between 75 and 95"C. When the temperature of the compressor is too low, the oil and gas can cause condensation of oil and gas due to low temperature. The water content affects the lubrication effect. Seriously, the inner wall of the cylinder will be rotted; improper cooling and insufficient cooling will cause the El temperature to exceed 95 °C, which will accelerate the oxidation of the air compressor oil and even cause accidents. The soundproof cover is operated in the air compressor. Not only does it have the effect of eliminating noise, but also because of its special structural form, it is more conducive to ventilation and heat dissipation. When the air compressor is running, the soundproof cover is closed, and the air inlet of the cooling fan can be reserved from the lower part of the soundproof cover. Into, these vents face the air compressor main engine, motor, air compressor oil gas drum and other parts, can effectively reduce the temperature of the corresponding position, improve the running stability of the motor. Therefore, the soundproof cover should not be opened during operation.
