  Industrial Chillers   are widely used, providing cooling water systems for industrial production and helping companies improve product output and quality. Therefore, we need to understand how to use chillers simply and correctly to avoid problems during use and delay production. Let us briefly understand the use of chillers from the following aspects. One: the protection of the chiller: 1. Check whether the voltage is normal, lack of phase, 2. Check and record the running current. 3. Measure and record whether the high and low pressure and temperature control temperature are normal. 4. Under normal conditions, the high pressure is 1.5MPa / the low pressure is 0.45MPa4 Check whether the interlocking control circuit device is loose and aging. 5. Check whether the oil level and oil temperature are normal. 6. Check the compressor for abnormal sound and abnormal vibration. 7. Refrigerant system test. 8. Overall commissioning and testing. 9. Regularly check whether the quality of ...

  Water cooled screw chiller   is a water to water chiller which compressor use semi-hermetic screw type. It’s high efficient water chiller system. The cooling water system including a water cooled screw chiller, a cooling tower, a water tank, and 3 water pumps. Water cooled screw chiller is widely used in the industrial cooling system. High pressure failure of the water cooled screw chiller is the common failure when it working. While how to deal with the high pressure failure of the water cooled screw chillers. Blow let’s talk with the Possible causes and solutions of the high pressure. 1. The temperature of the chiller is too high and the condensing effect is not good. The rated working temperature of the cooling water required by the water-cooled screw chiller is 30℃-35℃. The high water temperature and poor heat dissipation will inevitably lead to excessive condenser pressure. Occurs in the high temperature season, the reason for the high water temperature may be: cooling ...
