Here, the electric spark provides the detonation energy required for the explosion. There is no subsequent fuel in the compressor, and after the explosion occurs, it quickly weakens. Although the gas in the high-pressure chamber is difficult to release, some of the gas is discharged, and at the same time, the amount of air is increased, and the detonation of the explosion is faster, and the compressor casing is deformed. After the explosion, the process is adiabatic. After the volume increases, the pressure drops more, and the glass terminal fails to rush out. In summary, the main causes of such accidents are: on the one hand, the operating procedures in the hands of the operators do not discuss the handling methods and procedures of such abnormal accidents, and in addition, there is no careful analysis and inspection of hidden dangers, so the B factory is timely After the electricity, the inspection was directly used as the bad operation of the compressor air compression operation; on the other hand, the protection control of the air conditioning system during the assembly inspection of the manufacturing line did not receive sufficient attention. In the process of assembly line inspection of the outdoor unit, the operation check of the commercial inspection room is to use the general indoor unit of the manufacturer, and the protection function is less. It is mainly observed and judged by the operator. Therefore, the A factory fails in the case of the compressor stalled air conditioner and large current. Timely power outages and accidents.
Accident investigation and analysis, the author believes that the following lessons should be learned: (1) From the production line to the maintenance point, the possible adverse factors in the system should be fully estimated, and the corresponding abnormal inspection procedures should be determined to guide the operators to scientific operation. It is required that the welding assembly personnel, the operation inspection personnel, the on-site or the after-sales maintenance personnel should recognize the importance of reasonable operation; (2) require the operator (should be trained to obtain the employment certificate) with a high degree of responsibility and proficiency in operation. At the same time of the procedures, continuously improve the theoretical level and professional technical level, enhance the ability to analyze problems and solve emergencies; (3) increase the protection devices of the system during production, testing and maintenance, such as setting the low-voltage protection of general indoor units, High current protection of the air conditioner power supply, etc.
The baby grows up day by day, and likes swimming every day. In order to continue the project of baby swimming, the baby's head can also be raised at that time, and he no longer likes to be strangled by the neck. The baby also needs a wider field of vision. The depth of the baby swimming pool cannot reach the purpose of the baby's swimming (the baby's feet touch the bottom of the pool). If you want to swim in the original baby swimming pool, you must increase the baby's swimming height or increase the depth of the pool. The neck is moved to the base of the thigh, which increases the height of the baby's swimming. In order to solve these two problems, the Inflatable Baby Swim Seat was created.
The Inflatable Baby Swim Seat has multiple independent airbags, and there is an anti-leakage device in the air nozzle, which is safe and reliable. The swimming ring is carefully designed, made and comfortable to wear according to the characteristics of the baby's thigh. Proper use can prolong the use time.
