Analysis and improvement measures of Chen Jiangbo Han Zhenjiang oil company Sinopec pipeline storage and transportation company of Shengli Chen Jiangbo Han Zhenjiang air compressor exhaust pipe storage pressure problem analysis and improvement measures of oil and gas storage and transportation in the air compressor.                   Exhaust pipe storage pressure, oil and gas storage and transportation, the air compressor two cylinder and exhaust pipe of pressure caused by the badly damaged parts, affect the safe operation heat medium furnace.
         Through the analysis of the cause of the fault, the improvement measures are put forward, that is the installation of a gas pressure relief system in air compressor, which can effectively solve the problem of two cylinder and exhaust pipe storage pressure, the actual operation shows the installation of air compressor fault pressure relief system after downtime is reduced greatly, prolongs the service life of the equipment. To ensure the safe operation of heat medium heater.
         Key words: air compressor storage and pressure analysis and improvement measures. First, we said that the heating medium indirect heating furnace used by the first station of Shengli oil company from Dongying was imported from the United States, and the atomization mode of fuel oil was air atomization.
Compressed air is supplied by air compressor.
        The air after two stages compressed by the air compressor comes into the gas tank from the exhaust pipe and supplies the heat medium furnace in the form of atomizing wind and instrument wind.
        Two domestic type 1 oil free air compressors at the first station in Dongying (hereinafter referred to as the air compressor in parallel mode, one machine operation, one machine standby.
       The two problem is due to the fact that the amount of gas consumed during the operation of the heat medium heater can not be absolutely equal to that of the air compressor, so the exhaust volume must be adjusted within a certain range.
      The two domestic air compressors at the first station in Dongying were cut off the intake and stopped the way of suction, and the pressure regulator and the load reducing valve installed at the inlet of the air compressor were completed. The control gas source of the pressure regulator was drawn from the gas storage tank.
      When the pressure of the storage tank reaches the upper limit of the pressure regulator, the high-pressure gas enters the load reducing valve through the pressure regulator, and moves upward to close the intake passage. The air compressor stops breathing and exhausting, and it is in a state of idling. When the pressure of the storage tank drops to the lower limit of the pressure regulator .
      The pressure regulator to cut off the gas tank gas unloading valve, unloading valve under the action of the spring, down to open the air inlet channel, air compressor to load operation.
      The pressure trend of the one or two - stage cylinder in the normal operation of the air compressor is shown as shown in the diagram.
       It can be seen from the picture, when the air compressor with a load operation, a cylinder pressure from rising to about two from the cylinder pressure began to rise slowly when the air compressor idling, a cylinder pressure drop to flow into the pipeline should be quickly and smoothly.
      The two section control valve is mainly used on the automatic valve such as the electric valve pneumatic valve of the electromagnetic valve.
      Due to the rapid response of the automatic valve to the electric, the opening and closing time is short and the water hammer is easy to cause.
      Using two or more segments to control the shut-off valve, the liquid from flow to stop has a gradual process, which greatly reduces the occurrence of water hammer.
       In fact, the functions of the automatic valve and the slow open and closed manual valve are the same, which can extend the opening and closing time and reduce the water hammer of the pipe.
      Dual power pressure relief valve double power pressure relief valve is composed of the main regulating valve control valve accumulator and monitor.
      The valve can effectively control the rate of water shock and pressurization, and has the function of limiting the supercharging limit value of the monitoring point.
       The control principle is basically the same as that of the direct buffer tank. Only the regulating valve can better control the liquid pressure into the buffer tank and the hydraulic pressure from the buffer tank to the pipeline when the water hammer strikes, and the volume of the buffer tank can also be greatly reduced.
       The dual power relief valve can regulate the opening pressure of the valve and effectively prevent the harm of water hammer. It has been successfully applied to long distance pipelines and process pipelines, ensuring the safety of production operations.
        The date of a Zhang Yan teaches editing, analysis and improvement measures of Chen Jiangbo Han Zhenjiang oil company Sinopec pipeline storage and transportation company of Shengli Chen Jiangbo Han Zhenjiang air compressor exhaust pipe deposit analysis and improvement measures of pressure in Shandong province Jining road Dongying city telephone oil and gas storage and transportation in the air compressor exhaust pipe storage pressure, oil and gas storage and transportation, the air compressor cylinder two and the pressure caused by the exhaust pipe to save parts of serious damage, affect the safe operation of heat medium heater.
        Through the analysis of the cause of the fault, the improvement measures are put forward, that is the installation of a gas pressure relief system in air compressor, which can effectively solve the problem of two cylinder and exhaust pipe storage pressure, the actual operation shows the installation of air compressor fault pressure relief system after downtime is reduced greatly, prolongs the service life of the equipment.
