the pressure following a control valve is 0

How to make the CO2 compressor work?This article is to inform you about how the relevant CARBON DIOXIDE IS HOT compressor works. I will introduce you the detailed operating procedures. The correct operation may also bring good maintenance to the CO2 compressor, so it can be still important.main：Problem confirmationstart upCARBON DIOXIDE IS HOT compressor process system preparingMain steam line heat pipePreheating of harrow steam linesEstablish a shaft sealstopProblem confirmation Confirm that the carbon dioxide supply is sufficient;Confirm that the steam required to begin the unit is experienced and sufficient;Confirm that this cooling water of each cooler may be used;Confirm that the particular meter devices, regulators, switches along with instrument devices used with the unit are calibrated as well as used;Confirm that all electrical devices will be in good condition;Confirm that this safety valve of the unit and its auxiliary equipment has become commissioned;The unit's speed control system and anti-surge manage system are qualified for static commissioning;The emergency shutdown test belonging to the unit is qualified;carbon compressorstart up Make sure the turbine rotor seemingly stopped.The slide plate to the cranking device is removed to interlock the travel switch to make sure that the steam turbine cannot be started.Remove the shaft cover and use a ratchet wrench by the end of the worm the whole length.Push the worm to make the worm contact that worm gear and move the ratchet wrench clockwise in order to fully mesh the worm while using worm gear.Remove the ratchet wrench as well as attach the shaft cover after confirming that remember that it is engaged.Release the travel switch for cutting journey motor power of the particular cranking motor, start that turning motor, and that rotor will continuously move.CO2 compressor process program preparation Establish circulating chilling water of E19007 and E19008;The front and rear valves belonging to the second-stage inlet filter ANY are opened, and B is actually reserved;Open a large valve of K19001 to charge the K19001 cylinder with carbon dioxide;The venting valve HV19602, the cylinder guide, the E19007/E19008 pilot, along with the second-stage inlet filter A belonging to the K19001 second-stage outlet will be continuously discharged.Sampling and analysis in the oxygen content in the cylinder is not as much as 0. 5%;Close your discharge ports after passing the replacement;LICA19601, LICA19602 established 20% automatic injection;Main steam line heating water pipe Confirm that the hot water tank guide, the main steam line guide, the urgent situation shut-off valve body guideline, and the warm tube vent valve are completely open;Micro-open the bypass valve on the main steam valve, the pressure following a control valve is 0. 2-0. 3MPa, preheating for 15 to Half-hour, until the temperature from the main steam line reaches 150 °C or on top of.Gradually open the bypass valve belonging to the main steam valve, improve the temperature and temperature on the heating pipe, control the particular heating rate to 5~10 °C / min, the pressure increase rate is 0. 1 ~ 0. 15MPa / minutes, with the decrease involving steam condensate volume as well as need for warm plumbing and boosting, gradually closing the tiny heating pipe guide valve as well as warm pipe venting control device;When the steam force rises to 2. 96 MPa along with the temperature rises above 330 °C, the leading steam valve is absolutely opened, the heating pipe bypass valve and also the warm pipe guide are deterred, and the warm pipe vent valve maintains some opening degree.Preheating associated with exhaust steam lines Confirm the exit shutoff control deviceOpen exhaust pipe depleation valveOpen exhaust test valve drain valveStart steam pressure gauge main valveEstablish a the whole length seal Confirm that that turbine cylinder is totally open;Use the cooling water belonging to the steam seal condenser,Concur that the condenser guide U-shaped water seal has become established;To use the actual shaft seal steam chillier aspirator, first open this steam valve, then open the air valve;stop Stop turning the motor in the car;Manually disengaging the actual worm gear;Cover the shaft insure and press the stroke switch that cuts journey power of the motor to ensure the motor can not be started.Do not apply your oxygen compressor, hydrogen compressor operating experience to operate the CO2 compressor, although there are several links between the compressors, although more different.https://www.oxygen-compressors.com/Co2-Compressor-pl3326255.html
