The reason and solution for the problem of screw type cold water system

Screw water chillers for its operation with high efficiency, good cooling effect, wearing parts less, the failure rate is low, so in the market have tended to rise year by year trend. But a lot of people have been screw type water chiller cooling capacity problems plagued. Today, we will discuss the reasons and solutions to the problem of the shortage of the screw type chiller. Screw water chillers for its operation with high efficiency, good cooling effect, wearing parts less, the failure rate is low, so in the market have tended to rise year by year trend. But a lot of people have been screw type water chiller cooling capacity problems plagued. Today, we will discuss the reasons and solutions to the problem of the shortage of the screw type chiller.
1, filter blocking
When insufficient refrigeration screw chillers, can first check whether the filter is blocked. Among the filter, the filter is blocked and dry filter is blocked. This problem can only be cleaned when the problem can be normal operation.
2, automatic control valve
Can be observed before the expansion valve is too small or too large a reason, just can be adjusted to solve. Expansion valve filling agent leakage can choose to repair or replacement. Throttle valve dirty or ice block to clean. Solenoid valve damage on the repair or replacement to solve.
3, compressor bearing wear
Compressor bearing long-term wear, it will produce a gap larger, produced by refrigerating capacity will be insufficient. At this time through maintenance and replacement can be solved.
4, evaporator, condenser
With the evaporator is too small, can reduce the heat load of evaporator or replacement. Evaporator frosting is too thick, should be regularly dissolved cream. The outlet valve of the condenser or the liquid storage device is opened, and the liquid valve is opened properly. Lack of water or water temperature is too high, the water can be resolved by adjusting the water.
5, refrigerant
Refrigerant filling quantity is insufficient, too much refrigerant leakage can be solved by adding refrigerant. In addition, the refrigeration system of screw chillers in excess air, can be solved by the emission of air. Energy regulation indication is not correct there may be the indicator lamp is broken, can be resolved through the maintenance and replacement.
