Table 2: Air inlet temperature correction factor CFT

● The pressure loss of the pre-filter in the system must be considered when choosing the correction factor CFP of inlet pressure of dryer.

● Select the air inlet temperature correction factor CFT.

● Selection calculation formula: selection treatment capacity = actual treatment capacity÷(CFPXCFT)

Preventive measures for explosion accident of gas tank

The gas tank is one of the pressure vessels, and the pressure vessel is a special equipment. The State Bureau of Quality and Technical Supervision issued the Inspection Regulation on Safety Technology of Pressure Vessels, which has strict regulations on the design, manufacture, installation, quality inspection, operation, detection and maintenance management of pressure vessels, and must be strictly observed. Serious explosion accident may occur if any link is neglected

1. The pressure protection device in the air tank shall be set up to prevent the overpressure of the air tank. Once the overpressure occurs, the power can be cut off automatically. The pressure regulator and safety valve must be tested correctly to ensure the quality. The operators must be familiar with and abide by the safety operation rules of air compressor and pressure vessel.

2. For carbon deposition prevention measures, the brand of cylinder lubricating oil shall be reasonably selected, and the amount of lubricating oil shall be strictly controlled. The amount of oil shall not be too much or too little, and the technical documents of the equipment shall be followed.

Control the exhaust temperature ① Strengthen the spot inspection of the air compressor cooling system, such as reasonably selecting the cooling water quality, timely removing the scaling on the cooler pipe wall and cylinder water cooling wall, and controlling the temperature difference between the inlet and outlet of the cooling water; ② Reduce the gas temperature in the pipeline and gas storage tank, strengthen maintenance and improve the quality of accessories to ensure that the gas valve does not leak and prevent the gas from circulating and compressing; ③ Protective devices for exhaust temperature at all levels, gas temperature in the gas tank and cooling water temperature shall be set to automatically cut off the power supply in case of overheating. Strengthen suction filtration to prevent the gas dust and hard particles contained in the inhaled gas; Strengthen the cleaning of the air tank to prevent carbon deposition from being too thick; Improve the sealing effect of the stuffing box to prevent the oil in the crankcase from leaking into the cylinder and entering the air tank.

3. Prevention measures for pipeline vibration When designing compressed air pipelines, elbows, valves and reducers shall be minimized, or the curvature radius of pipe bending shall be larger to reduce the excitation force. The equipment shall be installed in strict accordance with the design requirements. For the pipeline in use that has generated vibration, a buffer can be added near the compressor. Although the air storage tank is also a buffer, if the area is not large enough, it should be increased appropriately to reduce the non-uniformity of pulsating pressure. If a section of pipeline is found to have strong vibration, the reason for the vibration shall be judged first. If it is not mechanical resonance, it can be solved by clamping and pressing the pipeline or adding a support to the pipeline, but it shall be carried out at an appropriate position of the pipeline. 4. The requirements for operators shall strictly implement various rules and regulations, operate carefully, and carefully fill in operation records or production process records to ensure safe production operation; In case of any abnormality in the air compressor system that endangers the safety, emergency shutdown measures shall be taken and reported to the superior in a timely manner. Any command against rules of harmful equipment shall be refused, and professional knowledge shall be studied hard to continuously improve skills.
