H/N compressor position operating procedures (production plan)

Precautions for operation at the compression post: Pay close attention to the inlet mercury column of a section. If it suddenly drops, open the second and first valves in time. In an emergency, open the second and second valves of the machine to control the mercury within the indicator, and send out a contact signal in time to contact the dispatcher and relevant positions. You should also pay attention to the pressure conditions of the second outlet and the third inlet. If necessary, turn on the small machine seven times and three times to avoid the phenomenon of negative pumping at the three-stage inlet. It is necessary to constantly observe the pressure changes of the second outlet and the third inlet. If the second outlet is overpressured and the three inlet pressure is low, the second outlet valve must be opened to maintain the second outlet pressure within the specification. At the same time, the seven outlet valves must be opened to avoid the three inlet pumping and accidents. (This situation may be caused by improper opening and closing valves of the carbonized inverted tower, or incomplete blowing and blockage of the inverted tower, resulting in blocked gas pipes and valves). And get in touch with the dispatcher in time and listen to the operation. Similar to compressor tripping, it is necessary to promptly check the respective problems with electricians and maintenance workers, report to the workshop, and follow instructions to determine whether it can be turned on to avoid further damage to the equipment. If a large machine suddenly trips, a signal to change the machine must be sent in time. When relieving pressure, the circuit valve must not be opened too sharply. If necessary, open each section to vent (open the total vent, close the total return) to relieve pressure upward. Pay attention to the pressure of each section to ensure that the pressure of each section is normal. Regularly pay attention to the circulating oil pressure and the oil filling situation of each point of the oil injector. Do not operate while sick. Regularly check valve air return, piston ring air leakage, oil drain valve and circuit valve internal leakage to ensure normal operation of the equipment. Strengthen inspections, listen to the sound of the transmission and cylinder, the motor current and temperature rise when the compressor is running, shut down the machine immediately if any problems are found, and follow emergency shutdown procedures if necessary. Strengthen oil and water drainage operations in each section to avoid accidents such as liquid entrainment and damage to the packing.

Compression operating procedures 1. A low-limit alarm device for the inlet pressure of the system and a parking interlock device for the Roots machine and the compressor should be installed. 2. Check valves should be installed on the pipelines for the compressor conversion, desulfurization, copper washing, and synthesis processes. 3. The air return valve on the main oil collecting tank of the compressor should be kept open, and it is strictly forbidden to hold back the pressure. Oil and water should be discharged slowly to prevent high pressure from flowing into low pressure and prevent static ignition. 4. Ensure that various pressure, temperature, current, voltage, alarm and other control devices are sensitive, accurate and reliable. 5. Strictly implement the operating procedures for starting and stopping. The turning device must be opened. It is prohibited to use the driving wheel for turning. 6. It is forbidden to start with load. 7. The water pressure and oil pressure should be kept normal, and the relevant pipelines should be smooth. 8. When the water jacket of the cylinder is cut off, it is forbidden to add cooling water immediately. It should be stopped and allowed to cool down naturally before processing. 9. When discharging oil and water, it is strictly forbidden to discharge oil and water too hard or too fast to prevent a large amount of air leakage. It is forbidden to discharge several compressors at the same time to prevent accidents caused by pressure fluctuations in the inlet main pipe and pressure suppression in the main oil tank. 10. During the process of starting and stopping the compressor, the pressure increase or pressure relief must be slow, and the pressure in each section must be stable to prevent gas from flowing back and preventing accidents caused by high pressure channeling and low pressure. 11. The air pressure test time should not be too long, and the compression ratio and outlet temperature of each section should be closely monitored and controlled. 12. Strict shift handover system and the system of "starting work three days early, and not being allowed to leave work until eight days on duty and not leaving for five days" system.

The poster didn't say what kind of compressor the post was for! I have the centrifugal one, but the others are gone.
