Natural gas chemical gas compressor is a kind of mechanical equipment widely used in chemical, petroleum and other industries, its role is to compress gas, increase gas pressure, so as to meet various process needs. However, due to long-term use and the influence of environmental factors, the compressor will inevitably have various failures, so mastering the correct maintenance method is very important to ensure the normal operation of the compressor and the stable operation of the production line.
Analysis of common faults and causes of compressors:
1.Compressor fails to start: It may be due to the power supply not being connected, the motor is faulty, the transmission system is faulty, etc.
2.Insufficient compressor pressure: It may be due to air valve leakage, stuffing box leakage, piston ring wear, etc.
3.Compressor power consumption: It can be due to inefficient transmission system, motor failure, lubrication system failure, etc.
4.High compressor vibration: It may be due to loose anchor bolts, unbalanced rotor, loose bearing housing, etc.
Compressor maintenance method:
1.For the fault that the compressor cannot be started, you should first check whether the power supply and motor are normal, and if there is a problem, it needs to be replaced or repaired in time;At the same time, check the transmission system for abnormal sound or stuttering, and adjust or replace parts if necessary.
2.For the fault of insufficient compressor pressure, corresponding measures should be taken according to the actual situation. For example, a valve leak can be solved by replacing the valve or adjusting the valve clearanceFor stuffing box leakage, you can replace the stuffing box or adjust the stuffing box gland to solve it;For serious piston ring wear problems, it can be solved by replacing the piston ring or reinstalling the piston ring.
3.For the fault of high power consumption of the compressor, the transmission system should be checked first, and if there is a problem, it needs to be adjusted or replacedAt the same time, check whether the motor is normal, if there is a problem, it needs to be repaired or replaced;In addition, the lubrication system should be checked for proper function, and if there is a problem, adjustments or replacement parts need to be made.
4.For the fault of large compressor vibration, you should first check whether the anchor bolts are loose, and if there is a problem, you need to tighten them;At the same time, check whether the rotor is balanced, and if there is a problem, a balance correction is required;In addition, the housing should be checked for looseness and, if there is a problem, adjustments or replacement of components are required.
Compressor precautions:
1.Perform regular maintenance on the compressor, including cleaning the cooling system, replacing the lubricating oil, checking the transmission system, etc.
2.Regularly inspect and maintain the motor, including cleaning the motor housing, replacing grease, checking the motor insulation, etc.
3.Regularly inspect and maintain the valve, including cleaning the valve, replacing the valve seals, checking the valve clearance, etc.
4.Regularly inspect and maintain stuffing boxes, including replacing stuffing box seals, adjusting stuffing box glands, etc.
5.Regularly inspect and maintain the piston rings, including replacing the piston rings, cleaning the piston ring grooves, etc.
6.Ensure that the compressor operating environment is dry and well ventilated, and avoid the influence of humidity and high temperature environment on the compressor.
7.Attention should be paid to safety specifications during operation to avoid illegal operation and misoperation.
Natural gas chemical gas compressor is one of the important equipment in chemical, petroleum and other industries, and its normal operation is very important for the stable operation of the production line and the safe production of the enterprise. Therefore, you should have an understanding and grasp of the common faults and maintenance methods of compressors. In actual operation, corresponding maintenance methods and preventive measures should be taken according to the actual situation to ensure the normal operation of the compressor and the stable operation of the production line. At the same time, the maintenance and maintenance of the compressor should also be carried out regularly to avoid equipment failure or damage.
