This article aims to let you know the relevantCO2 compressorworks. I will introduce you to the detailed steps. Correct operation can also bring good maintenance to the CO2 compressor, so it is still very important.
Condition confirmation
start up
Carbon dioxide compressor process system preparation
Main steam pipe heating pipe
Exhaust pipe preheating
Create shaft seal
停
Make sure you have enough carbon dioxide.
Make sure that enough steam is required to start the equipment.
Make sure to use the cooling water for each cooler.
Ensure that the instruments, controllers, switches and other instruments used by the equipment have been calibrated and used.
Ensure that all electrical appliances are in good condition.
Make sure to use the safety valve on the device and its accessories.
The equipment speed control system and overvoltage protection system are suitable for static debugging.
The emergency stop test of the equipment passed.
Confirm that the turbine rotor has completely stopped.
Pull out the sliding plate on the starting device to lock the limit switch to ensure that the steam turbine cannot be started.
Remove the shaft cover and install a ratchet wrench on the end of the worm.
Push the worm to make the worm contact the worm wheel, and then turn the ratchet wrench clockwise to fully mesh the worm and worm wheel.
After confirming that it is engaged, remove the ratchet wrench and install the shaft cover.
Loosen the travel switch, cut off the power of the crank motor, start the rotary motor, and the rotor will continue to rotate.
Establish circulating cooling water for E19007 and E19008;
Open the front and rear valves of the second-stage inlet filter A, and keep B;
Open the big valve of K19001 and fill the K19001 cylinder with carbon dioxide;
The exhaust valve HV19602, the cylinder guide device, the E19007/E19008 pilot valve and the secondary inlet filter A of the K19001 secondary outlet continuously discharge.
Sampling analysis of oxygen content in the cylinder is less than 0.5%;
After passing the replacement, close the outlet;
LICA19601, LICA19602 set 20% automatic injection;
Confirm that the gas cylinder duct, main steam pipe duct, emergency shut-off valve body duct and warm pipe exhaust valve are fully opened;
Slightly open the bypass valve of the main steam valve, the pressure after the control valve is 0.2-0.3MPa, and preheat for 15 to 30 minutes until the temperature of the main steam line reaches 150°C or higher.
Gradually open the bypass valve of the main steam valve, increase the temperature and temperature of the heating pipe, control the heating rate at 5~10°C/min, and the pressure increase rate at 0.1~0.15MPa/min, with the amount of steam condensed And when the heating pipe is needed and pressurized, gradually close the small heating pipe guide valve and the heating pipe exhaust valve;
When the steam pressure rises to 2.96 MPa and the temperature rises above 330°C, the main steam valve is fully opened, the heating pipe bypass valve and heat pipe duct are closed, and the heat pipe ventilation valve maintains a certain degree of opening.
Confirm the outlet shut-off valve
Open the exhaust pipe drain valve
Open the exhaust check valve and drain valve
Open the steam pressure gauge root valve
Confirm that the turbine cylinder is fully opened;
Use steam to seal the cooling water of the condenser,
Confirm that the U-shaped water seal of the condenser duct has been established;
To use the shaft seal steam cooler air extractor, please open the steam valve first, and then open the air valve;
Stop turning the motor of the car;
Disengage the worm gear manually;
Put on the shaft cover and press the travel switch that cuts off the power of the motor so that the motor cannot start.
Do not useOxygen compressor,Hydrogen compressor The operating experience of operating CO2 compressors, although there are some connections between the compressors, but more different.
