Second, the screw type industrial chiller icing alarm failure analysis and troubleshooting screw chiller with air-cooled screw chiller and water-cooled screw chiller points, if their operating set point is too low, or load changes Low, it is very likely that the chiller will report an ice failure. If there is such a failure, the user can solve it by resetting and adjusting the parameters.
Third, the screw-type industrial chiller system, there are complex noise analysis and troubleshooting methods Why chiller operator attention to listen to the sound of the unit running it? It is to find the fault as soon as possible and troubleshoot it. If the expansion valve of the screw-type chiller has a “click†sound, check whether the liquid line is blocked or whether the refrigerant is sufficient. If there is excessive vibration, support the pipe and check for loose connections.
Fourth, screw-type industrial chiller in the suction pipe frosting condensation failure analysis and troubleshooting screw chiller frost condensation, there may be improper expansion valve opening, you can adjust the opening of the expansion valve to solve . Another problem is that the amount of refrigerant is too small. It should be checked that the refrigerant is sufficient. If it is insufficient, the refrigerant should be replenished to the specified level.
Five, screw type industrial chiller liquid pipe frosting failure analysis and troubleshooting If the screw chiller liquid pipe frost, first look at the liquid valve is not open, it should be in the open position; then check the liquid filter Is the device blocked? If there is a blockage, replace the filter dry core in time.
Sharing and troubleshooting methods for screw-type industrial chillers
First, the Screw type industrial chiller exhaust pressure analysis and troubleshooting methods There are two main reasons for this problem, first, the lack of cooling water: we can check the condenser water flow and cooling water pump; water cooling screw type The chiller should also check that the cooling tower is operating properly. Second, condensation on the water side of the condenser: The condenser tube bundle should be cleaned to avoid the decrease in cooling capacity due to fouling.
