When the operating conditions of the screw chiller factory
restrict the compressor to be installed in a small enclosed space, its ventilation environment should be considered. It is necessary to add ventilation and exhaust equipment to facilitate circulation of air. The capacity of the ventilation and exhaust equipment must be greater than the exhaust volume of the compressor cooling fan, and the exhaust inlet position should be suitable for the hot exhaust outlet position of the compressor. Precautions for compressor installation of the screw chiller factory
1. The compressor shall adopt a unit with large bearing capacity, and its operating speed and acceleration shall be limited within the permitted range.
2. Try to install the compressor of the screw chiller factory
in a cool, clean and well-ventilated place to ensure that the air around the compressor is clean and the moisture content is minimized.
3. The air sucked by the compressor is not allowed to contain combustible gas and corrosive gas, so as not to cause internal explosion or internal embroidery.
4. Air-cooled machines should preferably have exhaust fans or air ducts to direct hot air out of the room to prevent hot air from circulating to the air inlet.
Commissioning of the new screw chiller factory
shall be carried out by commissioning technicians designated or approved by the manufacturer. The compressor cannot work under the exhaust pressure higher than that specified on the nameplate, otherwise the motor will be overloaded and burnt out.
When the screw chiller factory
is running, strictly check the running direction of the compressor. When reverse rotation is found, stop the machine immediately, cut off the power supply, switch any two of the three-phase lines, and restart the machine. Otherwise, the compressor of the screw chiller factory will be damaged (attention must be paid to each factory power supply overhaul!).
