Wrong operation of water-cooled chiller

The chiller plant is a very common piece of equipment that plays an important role in industrial processes that require cooling, and the right things to do to get the business to produce better and faster, but often occur in the customer's facility Some wrong operation, these operations will cause some damage to the device.

In the actual operation of the chiller, there are often the following misconduct:

1, did not turn on before the unit does not need to open the condenser on the inlet valve caused by channeling water. A portion of the cooling water backflow never flows from the condenser of the power unit, reducing the flow of cooling water in the condenser of the power unit being operated, causing the condensation pressure to rise. Host operating current increases. Unit cooling capacity decreased, the serious will make the unit stop running. Not only waste electricity, but also reduce the cooling effect, but also easy to damage the equipment.

2, due to a misoperation, the host of condensation pressure and cooling water outlet temperature. To the operator caused by misjudgment. Mistakenly believe that the cooling water is not enough to open large condenser inlet valve and cooling water pump outlet valve, and some also increase the cooling tower fan, resulting in pumps, cooling towers fan power consumption increased.

3, what is more, blindly to open a cooling water pump. Although increasing the cooling water pump can indeed reduce the cooling water temperature and condensing pressure, but after all, a pump running power wasted. So it is wrong to add the wrong water cooling system The correct method of operation is: before starting the unit will not need to run the condenser inlet valve closed. Prevent channeling water. Open the condenser valve to be run on the unit out of the valve (usually the valve normally open, inlet valve on demand, off. Condenser, evaporator are the same) turn on the appropriate cooling water pump. Adjust the condenser into and out of the water pressure dropped to about 68.6kPa (0.7 kg / cm :) or so (pressure drop to overcome the resistance of the pipeline principle, lower some energy-saving effect is better). If the condenser inlet and outlet pressure gauge pointer swing too large, indicating the cooling water system has air. Need to exhaust air to be normal pressure gauge to continue to the next step. Operation, regardless of the number of units to open a few, are a cooling water pump to a host (to match the same).
