In the normal operation of the chiller unit, if unexpected equipment failures or sudden power outages, water cuts, or other special situations occur due to external reasons, which may cause harm to the unit, emergency measures should be taken to stop the unit in the shortest possible time, that is, emergency shutdown. The general procedure for emergency shutdown is:
① Stop the compressor;
② Close the supply valve and throttle valve at the outlet of the storage tank or condenser;
③ Stop the oil pump:
④ Stop the cooling water pump, cooling tower fan, and chilled water pump;
⑤ Cut off the power supply.
When restoring power or water supply, first keep the liquid supply valve closed and start according to the normal procedure. When the evaporation pressure drops to a certain value (slightly lower than the evaporation pressure under normal operating conditions), then open the liquid supply valve to put the chiller unit into normal operation.
What are the contents of daily inspections and records for maintenance of central air conditioning cooling towers
As an essential key equipment in industrial circulating water systems, the stable operation of central air conditioning cooling towers directly affects the efficiency and safety of the entire production process. Therefore, regular maintenance and upkeep of the cooling tower are particularly important. What are the contents of daily inspection and recording of cooling tower maintenance? Guangdong Tailing Air Conditioning solves your doubts.
1. Appearance inspection: Firstly, the cooling tower casing should be checked for damage, rust, or deformation to ensure structural integrity and no water leakage. At the same time, observe whether the air inlet and outlet are unobstructed to prevent debris from blocking the ventilation effect. 2. Water level and quality monitoring: Check whether the water level in the cooling water tank remains within the normal range and whether the water quality is clear and free of impurities. Regularly monitor water quality indicators, such as pH value, hardness, chlorine content, etc., to ensure that the water quality meets usage requirements and prevent scaling, corrosion, and other issues from occurring.
3. Running sound and vibration: Listen to whether there are any abnormal sounds during the operation of the cooling tower, such as bearing wear sounds, motor abnormal sounds, etc. At the same time, observe whether there are any abnormal vibrations in the tower body and ancillary equipment, and promptly detect and deal with potential faults.
4. Temperature and pressure monitoring: Record the inflow of cooling water
