高压报警故障现象：压缩机启动运行后，其高压压力一直上升达 到设定保护值

High pressure alarm <br>Symptom: after the compressor starts operation, high pressure which has been increased up <br>to the set protection value 2.0mpa tripped, the fault lights. <br>Processing method and inspection items: <br>1) Check the cooling water pump configuration and operation (a reasonable choice in line with the flow unit <br>pumps and the amount of lift). <br>2) Check the cooling water passing through the filter has not blocked (clean filter). <br>Temperature difference 3) Check the condenser out of the water, normally 3-5 ℃ (such as a temperature of greater than <br>5 ℃ need to increase the flow rate). <br>4) Check the fan is normal (should wind up). <br>5) Check the operation of the cooling tower, such as belts are tightened, the fan and the sprinkler <br>whether inversion (adjust the tightness of the belt, and the sprinklers varying the fan <br>running direction).

High-voltage alarm<br>Fault phenomenon: After the compressor starts operation, its high pressure has been rising up to<br> To set the protection value of 2.0mpa jump, the fault light is on.<br>How to handle and check items: <br>1) Check the configuration and operation of the cooling water pump (reasonable selection in line with the unit flow)<br> pump of magnitude and head).<br>2) Check that the cooling pipe way filter is blocked (cleaning filter).<br>3) Check the temperature difference between the condenser in and out of the water, normal 3-5 degrees C (if the temperature is greater than<br> 5 degrees C, increase the flow).<br>4) Check that the fan is OK (the wind should be up).<br>5) Check the operation of the cooling tower, such as whether the belt is loose, fan and sprinkler<br> whether the belt is reversed (adjusts the tightness of the belt, changes the fan and sprinkler<br> direction of operation).

High voltage alarm<br>Fault phenomenon: after the compressor is started and operated, its high-pressure pressure has been rising up to<br>Trip to the set protection value of 2.0MPa, and the fault light is on.<br>Handling methods and inspection items:<br>1) check the configuration and operation of the cooling water pump (reasonable selection conforms to the unit flow)<br>Water pump with capacity and head).<br>2) check whether the filter of cooling water pipeline is blocked (clean the filter).<br>3) check the temperature difference between the water in and out of the condenser, normally 3-5 ℃ (if the temperature is higher than<br>The flow rate needs to be increased at 5 ℃.<br>4) check whether the fan is normal (the wind direction should be upward).<br>5) check the operation of the cooling tower, such as whether the belt is loose, whether the fan and water spray<br>Whether the device reverses (adjust the belt tightness, change the fan and Sprinkler's<br>Operating direction).<br>
