Analysis of the influence of 1 air bending machine fault on light economy attack
1.1 operation sequence of air activated machine
The two air bending machines are connected in parallel through pipelines and then connected with the dry depth system.
The yield air discharged from the air compressor is dewatered remotely by the drying system, and then traced into the air tank. The maximum working pressure is 0.75mpa.
In the normal start-up state, only one of the two air compressors needs to be started to meet the production needs, while the other one is mainly to ensure the normal operation of production, and it is temporarily opened in an emergency state to meet the operation requirements.
When the air compressor cutting pressure is higher than the pressure of air relay storage, the air compressor starts to add my compressed air, on the contrary, the air compressor starts unloading to stop the compressed air.
The compressed air that can be pulled by the air is directly used for the pneumatic regulating network of the production device. Through the connection and adjustment between the above devices, the air compressor can maintain the pressure in the air base tank and provide a moderate holding state.
1.2 description of the influence of air compressor fault on light economy and natural equipment () the light hydrocarbon installation is expected to be in operation. Since the standby air compressor and the working machine are not interlocked, when the working machine has special phenomena such as fault, accident, etc., the standby machine does not realize self starting, and the derivative empty machine is transferred into the control room of light heat device without any operation signal The above continuity characteristics often take a long time to solve, which directly affects the quality of light hydrocarbon surface treatment itself, resulting in direct economic loss.) Once the air pressure is shut down quickly due to its own fault, the light return system will have some mechanical phenomena due to accidents. However, there is no indication of air pressure and fault shutdown in the control room of the light economic device, so the operator can not timely and effectively eliminate and deal with this fault due to the pressure regulation relationship between the air compressor and the air storage butterfly The influence is that there is no only surface air in the production unit or the surface air only in the production unit is lower than the minimum working pressure required by the pneumatic compressor. For the impact, the change of this pressure will lead to the loss of classification of the pneumatic lubrication itself.
The role of pneumatics is very important to the light economy unit. The loss of both pneumatic and pneumatic components will lead to the normal operation of the whole light hydrocarbon unit, such as temperature, pressure and liquid level, which is difficult to realize the normal operation and management of the whole light hydrocarbon unit. It is very easy to cause the whole light economic unit to operate under the conditions of over temperature and overpressure, which will bring potential safety hazards to the normal production of the whole unit and directly affect the smooth operation of the hydrocarbon unit,
