How dangerous is seasonal flu?
Seasonal flu is an acute respiratory infection caused by influenza virus. The disease often appears in winter and spring, when the body cannot respond to changes in weather. If the patient is not treated early and properly, dangerous complications can occur.Changing weather and erratic sunshine and rain are the times when the incidence of influenza increases, causing many serious health consequences. A person infected with flu is sure to spread it to everyone in the family, to colleagues, neighbors, and relatives. The consequences of flu cause superinfection, respiratory infections (pharyngitis, sinusitis, bronchopneumonia,...) and even types of flu that cause complications like myocarditis and conjunctivitis. Prolonged flu causes many health problems (memory loss, seizure disorder,...)

This morning, August 6, 2024, EMIN Vietnam Joint Stock Company organized seasonal flu vaccination for employees in the Hanoi area. Below are some notable images:
"Silent capacitor burnout" refers to a phenomenon where a start capacitor gradually loses capacitance without exploding or emitting smoke, making it difficult for the user to detect the issue until the motor has sustained severe damage. The appliance continues to operate but runs sluggishly, overheats, and consumes twice the normal amount of electricity. Without periodic inspections, a component costing only a few tens of thousands of dong could force you to replace the entire motor, air conditioner compressor, or ceiling fan an expense running into the millions.
An analog multimeter can still be used to quickly check if a capacitor is shorted, open-circuited, or capable of charging and discharging. However, if precise capacitance measurement or an assessment of capacitor quality is required, a digital multimeter or LCR meter will yield more reliable results
By simply measuring the rotational speed (RPM) and comparing it against design specifications or historical maintenance data, engineers can detect signs of belt slippage, speed reduction, or power loss without needing to disassemble the motor
Measuring pump shaft speed helps determine the equipment's actual rotational speed (RPM), allowing for comparison against design specifications to detect issues such as belt slippage, incorrect gear ratios, abnormal motor operation, or failure to achieve the desired flow rate. Depending on operating conditions, engineers may choose a laser tachometer, a contact tachometer, or a stroboscope
RPM measurements can certainly be used to calculate conveyor belt speed (m/min) if the drum diameter is known. Learn about the calculation formula, practical examples, and how to take accurate measurements using a tachometer
