display cooler installation of refrigeration equipment
machine body leveling Put the spirit level on the processing datum surface of the freezer, and adjust it to level with the horn. The installation accuracy is that the horizontality of the vertical and horizontal directions of the fuselage should not be greater than 0.2/1000 mm. For chillers with a common base, an appropriate location should be selected as the reference plane according to the host structure.
motor installation The main job of installing the motor is to adjust the center line of the motor to be in line with the center line of the compressor. The connection between the motor and the compressor shaft has a pulley connection and a coupling connection, so the main work of the motor installation is the alignment of the pulley or the coupling. If the motor and the compressor do not have a common chassis, install the motor and the motor guide rails while installing the compressor, and use the cable method to make the motor and the compressor pulley on the same plane. If it is a direct drive, the two shafts of the motor and the display cooler compressor must be adjusted to be concentric, so that the radial deviation is not more than 0.3 mm, otherwise the elastic rubber is easy to break, and it will bow and cause vibration.
anchor bolt grouting After the compressor body and motor are installed, the anchor bolt grouting can be carried out. Before grouting, the levelness of each part must be fully retested, and the concealed engineering records of the horn must be made. The concrete grade for grouting should be higher than that of the foundation. Generally, fine gravel concrete is used. When grouting, there should be no pause in the middle, and the grouting should be finished at one time. The grouting should be layered and compacted. Do not bump the device during operation. After irrigation, water should be sprayed for maintenance to avoid cracks. The curing time depends on the temperature, but at least 8 days. After the anchor bolt concrete is solidified, the shim iron is leveled again: after the leveling is qualified, the anchor bolts are tightened (the nut is exposed by 2 to 3 buckles), and then the shim iron is welded firmly by electric welding: finally the second grouting is performed.
