Air Cooled Screw Chiller How To Exclude It?
- Jun 02, 2017 -

Fans are generally installed on the top of the air-cooled screw chillers, and some users choose to install on the side as required. Air Cooled Screw Chiller And for the use of fan to heat the screw chillers, we call the air-cooled screw chillers, its installation environment must be kept open and air easy to circulate, so as not to affect the cooling effect of air-cooled screw chiller.


However, in general, Air Cooled Screw Chiller the mechanical and electrical equipment class, in the installation or use of the process will certainly have some failures. So, what are the common malfunctions of wind-cooled screw chillers? How should enterprises be excluded?

Air-cooled screw chillers have too much noise:

1, bearing parts wear/gap too large: if wear should be replaced in a timely manner, the gap too large can be directly adjusted to the appropriate position;

2, the speed is too high: can be improved by reducing the speed, if not yet resolved should be replaced by the fan;


Second, air-cooled screw type chiller fan motor temperature rise too high:

1, flow exceeding rating: At this time can turn off small valve;

2, motor or power supply problems: Find the motor and power sources;


Third, air-cooled screw type cold water fan bearing temperature rise too high:

1, lubricating oil (grease) is not enough or poor quality: if the lubricating oil is not enough, the enterprise should be filled to the required parts, if the quality is poor, Air Cooled Screw Chiller then the bearings should be cleaned after the replacement of qualified lubricating oil (grease);

2, fan shaft and motor shaft different heart: should adjust concentric;

3, bearing damage: At this time should replace the new bearings, or directly contact the manufacturer to replace the cold water machine;


Four, air cooling screw type Chiller fan of the small amount of air flow:

1, check the rotation direction of the impeller is reversed, this can be replaced by the motor any two wiring of the location to solve;

2, the opening of the valve is not enough, Air Cooled Screw Chiller as well as loose belt and speed is not enough: can have been adjusted through the valve open to the appropriate opening, the belt tensioning or replacement, and check the voltage measures to detect bearings;

3, into the wind or outlet, pipe blockage: Check into the wind/outlet, and clear the blockage;

4. The connection between the impeller and the shaft may be loose, which can be eliminated by means of direct fastening, if the impeller and inlet gap are too large, they should be adjusted to the appropriate clearance.


Air-Cooled screw chillers fan, equivalent to water-cooled chiller Cooling tower Cooling system, if the heat dissipation effect is not good, then air-cooled screw chiller cooling capacity is absolutely insufficient, directly affect the company's demand for chilled water. Therefore, Air Cooled Screw Chiller it is necessary to carry out regular inspection, maintenance and maintenance of air-cooled screw chiller, which can not only reduce the failure rate of air-cooled screw chiller, but also prolong the service life of air-cooled screw chiller.
