While using continuous development of CARBON DIOXIDE refrigeration technology and heat pump technology, CO2 compressors have also been greatly developed, and related manufacturers in your own home and abroad have successively introduced CO2 compressors. It is not easy to choose a great CO2 compressor from countless manufacturers. When you purchase it, you should also focus on the maintenance of CARBON compressor.

Maintenance associated with mechanical condition of CARBON DIOXIDE IS HOT compressor unit
Vibration

If the turbine is started, it truly is found that the vibration benefit is high, that can be, the speed is stopped as well as the cause is checked. If the cause does not seem to be caused by an poor operation, such as a good improper temperature rise, stop and check each of the tests described in this table below. The vibration amount suddenly increases during natural operation, reducing the weight and/or downtime. In the situation of increasing amplitude, research the phenomenon and adjust the operating conditions to get analysis. If the unit vibration is too much, the cause should be found as well as the corresponding treatment should become performed.

Unusual sound

The inspection must be carried out carefully underneath low-speed operating conditions. After the speed increase, the sound is mixed with all the sound of the rotating sound as well as noise entering the water. Therefore, it is difficult to get the sound source. The abnormal sound is often of this particular vibration, so the sound really should be checked.,find the actual reason, and deal by using it accordingly.



Increased bearing temps

The increase in bearing temperature is due to bearing metal damage, reduced level of lubricating oil, low lubricating acrylic pressure, high lubricating essential oil supply temperature, high rotor vibration benefit, and abnormal thrust. If the bearing metal temperature out of the blue rises or exceeds 125°C, quit and check the keeping and perform the similar treatment.



Bearing temperature fluctuation

In the case of bearing temperature fluctuations, please check the things in the table. After checking the different items, the temperature fluctuations should certainly stopped and the corresponding treatment really should be carried out.



Maintenance regarding process system for CARBON DIOXIDE compressor unit
The inlet and electric outlet pressures and temperatures of each one section of the unit really should be closely monitored to prevent the machine from entering the spike condition. At the exact same time, the unit is usually prohibited from over-temperature along with over-pressure operation, resulting throughout equipment damage or safety valve take-off;

During your inspection, it should be noted which the output valve position belonging to the anti-surge controller should be consistent considering the on-site valve position;

Look into monitoring whether the temperature and pressure from the main steam of the turbine are while in the normal range;



Normal maintenance belonging to the unit shaft seal condensing system
Check that the U-shaped water seal guides the water to flow out;

Check if the vacuum of the actual condenser is normal;



Regular operation
Turn the start switch from the standby pump to the actual "STOP" position, and reserve the pump to confirm an obvious condition;

Confirm that the inlet and outlet valves in the backup pump are totally open, start the standby push, and confirm that your standby pump is running normally;

After the standby pump outlet pressure is steady, stop the main pump. If it is essential repair, the pump will probably be cut off after electricity off. If no maintenance is required, the pump switch can be automatically placed.

Opening the exhaust valve with the standby device;

Open the particular communication valve and vent the spare equipment;

Keep the exhaust state regarding 10min, warm up this spare equipment, avoid the oil temps change and cause shock to the unit

Close the exhaust valve and equalize the particular backup equipment;

Move the switching handle inside correct direction (for the actual alternate oil cooler, the cooling water ought to be used first), and utilize spare equipment;

Close the communication valve and open the exhaust valve in the cutting device to reduce pressure;



If you have purchased other machines for example oxygen compressors, hydrogen compressors, or anything else.,don't forget to perform the maintenance on weekdays, which will save you some huge cash.
