The role of the industrial chiller is to reduce the temperature of the refrigerant water to become the chilled water of the required device. Any machine will receive friction resistance during operation. Friction will not only reduce the efficiency but also cause loss to the equipment itself. At this time, we will maintain and lubricate the equipment. Let's understand the maintenance and lubrication methods of industrial chiller.

I. Maintenance of industrial chiller

1. In order to maintain the chiller, always check the turbidity of the cold and dry water cooling water. Replace the chiller cooling water if necessary. And check the operation, operation, dripping, leakage of the chiller's water supply system.

 

2. Check whether the pump of the chiller is working normally, moldy, and the switch is effective. If there is an abnormal situation, deal with it in time.

 

3, the chiller refrigeration compressor repair and maintenance, under normal circumstances, the chiller should be replaced in 30 chilled oil and dry filters. Replacement after six months. It depends.

 

4. During the initial operation of the chiller, carefully observe the oil return of the compressor and keep it clean. If the oil of the chiller is not clean enough or oil drops, add oil or oil. This can avoid poor lubrication.

 

5. Always observe the operation of the compressor equipment, check the exhaust temperature, seasonal changes, and pay special attention to the operation of the chiller when the temperature difference changes. If it is abnormal, check it in time and adjust the condensation temperature and liquid supply of the system.

 

6, determine the sound for the chiller. Listen to the operating sound of water pumps, cooling towers, compressors, fans and other equipment. If it does not meet the routine, you should maintain the chiller in time. For the repair parts, refer to the vibration of the compressor, exhaust pipe and feet.

 

Second, the lubrication method of industrial chiller

1.Drip oil lubrication method

Use the oil cup and the oil pipeline to send the lubricating oil to the parts that should be refueled, or fill the lubricating oil with an oil pot on time.

 

2.Pressure lubrication method

Mechanically lubricate the lubricating oil pressure automatically. This method is used in large and medium-sized compressors with crossheads.

 

3.Injection lubrication method

The sprayed oil mist will follow the gas into the lubricating place such as the cylinder, such as super sliding vane compressor, high pressure compressor and screw compressor.

 

4. Oil ring lubrication method

The rotating shaft is used to drive the oil ring which is movably sleeved on the shaft. The oil ring brings the oil in the oil pool into the bearing and enters the circulation lubrication.

 

5, splash lubrication method

The oiling rod mounted on the connecting rod throws the oil up and splashes to lubricate the lubricating parts, so the cylinder and the moving mechanism can only use the same type of lubricant. This method is mostly used in small compressors without crossheads. It is difficult to filter and it is inconvenient to operate. The oil level of industrial chiller must be strictly controlled.

 

The above is the maintenance and lubrication method of industrial chiller. The above content hopes to help everyone.
