Considering the continuous development of CARBON DIOXIDE refrigeration technology and high temperature pump technology, CO2 compressors are also greatly developed, and related manufacturers at your home and abroad have successively introduced CO2 compressors. It seriously isn't easy to choose a great CO2 compressor from a great number of manufacturers. When you obtain it, you should also look closely at the maintenance of CARBON compressor.

main:

Maintenance associated with mechanical condition of CARBON compressor unit

Maintenance connected with process system for CARBON DIOXIDE IS HOT compressor unit

Normal maintenance of the unit shaft seal condensing procedure

Normal operation



Maintenance with mechanical condition of CARBON DIOXIDE compressor unit
Vibration

When the turbine is started, it is found that the vibration price is high, that is actually, the speed is stopped as well as cause is checked. If the cause does not seem to be caused by an inappropriate operation, such as a improper temperature rise, stop and check all the tests described in this table below. The vibration stage suddenly increases during normal operation, reducing the heap and/or downtime. In the case of increasing amplitude, research the phenomenon and transform the operating conditions with regard to analysis. If the unit vibration is too high, the cause should be found and the corresponding treatment should always be performed.

CO2 compressor

Unnatural sound

The inspection must be carried out carefully underneath low-speed operating conditions. Following speed increase, the sound is mixed with all the sound of the rotating sound plus the noise entering the water. Therefore, it is difficult to see the sound source. The abnormal sound is often associated with the vibration, so the sound ought to be checked.,find the true reason, and deal with it accordingly.



Increased bearing temp

The increase in bearing temperature is because of bearing metal damage, reduced amount of lubricating oil, low lubricating petrol pressure, high lubricating petrol supply temperature, high rotor vibration valuation, and abnormal thrust. If your bearing metal temperature all of a sudden rises or exceeds 125°C, halt and check the showing and perform the equivalent treatment.



Bearing temperature fluctuation

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



Maintenance involving process system for CARBON DIOXIDE IS RED-HOT compressor unit
The inlet and outlet pressures and temperatures of each one section of the unit really should be closely monitored to prevent it from entering the uprise condition. At the similar time, the unit is actually prohibited from over-temperature plus over-pressure operation, resulting with equipment damage or safety valve take-off;

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

Pay attention to monitoring whether the temperature and pressure in the main steam of the turbine are inside normal range;



Normal maintenance in the unit shaft seal condensing method
Check that the U-shaped water seal guides the lake to flow out;

Find out if the vacuum of your condenser is normal;



Normal operation
Turn the start switch in the standby pump to that "STOP" position, and reserve the pump to confirm the standard condition;

Confirm that the inlet and outlet valves with the backup pump are completely open, start the standby push, and confirm that the standby pump is working normally;

After the standby push outlet pressure is stable, stop the main pump. If it is essential to repair, the pump might be cut off after electric power off. If no maintenance is required, the pump switch is automatically placed.

Opening the exhaust valve in the standby device;

Open the actual communication valve and port the spare equipment;

Sustain the exhaust state for 10min, warm up the actual spare equipment, avoid the oil heat range change and cause shock on the unit

Close the wear out valve and equalize the actual backup equipment;

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

Close the communication control device and open the exhaust valve from the cutting device to ease pressure;



If you have purchased other machines including oxygen compressors, hydrogen compressors, and so on.,don't forget to carry out the maintenance on weekdays, which will save you some huge cash.
