The function of lubricating oil one
1. Dynamic sealing is formed between the screw and the compression chamber, as well as between the male and female screws, reducing the need for sealing
Leakage of refrigerant from the high-pressure side to the low-pressure side during compression;
2. Cooling the compressed refrigerant, oil is sprayed into the compressor to absorb the refrigerant
The heat generated by gas during compression reduces the exhaust temperature;
3. Forming an oil film between the bearings and screws to support the rotor and provide lubrication;
4. Transmission of pressure differential force, driving capacity adjustment system, through the loading and unloading of the compressor
The action of the load electromagnetic valve adjusts the position of the capacity adjustment slider to achieve compressor capacity adjustment control;
5. Reduce operating noise.

5. Reduce operating noise.
The key to maintaining the normal operation of the compressor is the lubrication oil system inside the compressor
There are three issues with general lubricating oil
1. Foreign objects mixed in, causing lubricating oil contamination and clogging of the oil filter;
2. High temperature effect causes deterioration of lubricating oil and loss of lubrication function;
3. System water pollution, acidification, and erosion of motors.

Compressor refrigeration oil inspection and replacement
For system manufacturers, the detection and replacement cycle of compressor refrigeration oil is related to the process control of their production process. If the cleanliness control of the evaporator, condenser, and system pipelines is good, then relatively speaking, there will be less pollutants entering the compressor, and the inspection and maintenance cycle can be relatively extended.

Main monitoring indicator one
1. PH index: Acidification of lubricating oil can directly affect the service life of compressor motors, so it is necessary to regularly check whether the acidity of lubricating oil is qualified. Generally, lubricating oil with an acidity below PH6 must be replaced. If the acidity cannot be checked, the drying filter of the system should be replaced regularly to maintain the dryness of the system in a normal state;
2. Pollution index: If the pollutant in 100ml of refrigeration oil exceeds 5mg, it is recommended to replace the refrigeration oil;
3. Water content: If it exceeds 100ppm, the refrigeration oil needs to be replaced.

Replacement cycle one
Generally, lubricating oil should be checked or replaced every 10000 hours of operation, and after the first operation, it is recommended to replace the lubricating oil and clean the oil filter every 2500 hours. The residue from system assembly will accumulate in the compressor after formal operation. So the lubricating oil should be replaced every 2500 hours (or 3 months), and then replaced regularly according to the cleanliness status of the system. If the system cleanliness is good, it can be replaced every 10000 hours (or every year). If the exhaust temperature of the compressor is maintained at a high temperature for a long time, the deterioration of the lubricating oil will progress quickly. It is necessary to regularly (every 2 months) check the chemical properties of the lubricating oil, and replace it if it is not qualified. If regular inspections are not possible, the following suggestion table can be followed for implementation. Replace. Explanation: The operation period is calculated based on a daily operation of 16 hours

Operation method for replacing refrigeration oil
1. Replacing refrigerant oil without internal cleaning:
The compressor performs a pump collection action to recover the system refrigerant to the condenser side (note that the minimum suction pressure during the pump collection action is not less than 0.5Kg/cm2G). The refrigerant inside the compressor is discharged, leaving some internal pressure as the power source, and the refrigerant is discharged from the oil discharge angle valve of the compressor.

1. Replace the refrigeration oil and perform internal cleaning:
The oil discharge action is as described earlier. After the refrigeration oil is completely drained and the pressure inside and outside the compressor is balanced, use an Allen wrench to loosen the flange bolts, remove the oil filter joint and the cleaning hole flange (or oil level switch flange), remove the pollutants in the compressor oil tank, and check if the oil filter mesh is damaged. Blow out the oil sludge, pollutants, etc. on it, or replace it with a new oil filter. Note that when replacing, the filter interface nut should be tightened and sealed to prevent internal leakage; The gasket inside the oil filter joint must be replaced to prevent internal leakage; It is also recommended to update other flange gaskets.

Notice 1
1. Different grades of refrigeration oil should not be mixed, especially mineral oil and synthetic esters
Oil cutting should not be mixed;
2. If replacing with different grades of refrigeration oil, be sure to remove any remaining refrigerant in the system
Remove the frozen oil;
3. Some oil products should not be exposed to refrigeration oil for a long time due to their hygroscopic properties
In the air. Install E parts to minimize exposure time and perform vacuum pumping operations as much as possible;
4. If there has been a compressor motor burnout fault in the system, special attention should be paid when replacing the new machine
Pay attention to removing residual acidic substances from the system, and check the acidity of the refrigeration oil after 72 hours of debugging and operation. It is recommended to replace the refrigeration oil and dry the filter to reduce the possibility of acid corrosion. After about a month of operation, check or replace the refrigeration oil again;
5. If there has been an accident of water ingress in the system, special attention should be paid to removing the moisture dry
Clean, in addition to replacing the refrigeration oil, special attention should be paid to testing the acidity of the oil, and timely replacement with new oil and drying filters.
