The common causes of gasification pressure regulating skid failure are mainly the following:
Mechanical component problems
Valve failure: After long-term use of the regulating valve, the valve core and valve seat may be worn and corroded, resulting in poor valve closure or reduced regulation accuracy. Aging of seals can also cause valve leakage, affecting pressure regulation.
Loose connectors: The connecting bolts and nuts between the pipeline and the equipment may loosen due to vibration or loose installation, causing gas leakage, and also affecting the stability of the system.
Control and monitoring system failure
Sensor failure: If the pressure sensor, flow sensor, etc. fail, the measurement data will be inaccurate, and the control system will not be able to make precise adjustments according to the actual situation, making the output pressure unstable.
Control system failure: Control devices such as programmable logic controllers (PLCs) may not be able to issue control instructions normally due to program errors, hardware damage, etc., affecting the normal operation of the pressure regulating skid.
Gas impurities and blockages
Impurity accumulation: Impurities and particles contained in the gas may accumulate in the pressure regulating skid, blocking the pipeline, valve or filter, affecting the normal flow of the gas, causing pressure fluctuations or failure to reach the set value.
Icing and blocking: In low temperature environment, the moisture in the gas may freeze, blocking the pipes and valves, affecting the normal operation of the equipment.
External environmental influence
Temperature change: The drastic change of ambient temperature may cause the equipment material to expand and contract, affecting the sealing and adjustment performance of the valve, and also have a certain impact on the accuracy of the sensor.
Vibration and shock: The vibration of nearby equipment or the impact of the outside world may loosen and shift the parts of the pressure regulating skid, affecting its normal operation.
