The following are the inspection methods and steps of the magnetic flap level gauge :
1. The tapping pressure method often encounters the phenomenon of good and bad operation of the instrument. Most of this phenomenon is caused by poor contact or virtual welding. For this case, tapping and hand pressing can be used.
The so-called "knocking" is to gently knock the board or part through a small rubber hammer or other tapping object to see if it will cause an error or a downtime. The so-called "hand pressure" is when the fault occurs, after the power is turned off, the inserted components and the plug and the seat are again pressed by hand, and then the power is turned on to try to eliminate the fault. If you find that the case is normal, and then knocking is not normal, it is best to first re-insert all the connectors and try again. If the brain is unsuccessful, you have to find another way.
2. The observation method utilizes vision, smell, and touch. In some cases, damaged components will change color, blister or burnt spots; burnt devices will produce some special odor; short-circuited chips will be hot; visible or desoldered parts can also be observed with the naked eye. .
3. Exclusion method The so-called elimination method is a method for judging the cause of a fault by plugging in some plug-in boards and devices inside the machine. When the instrument returns to normal after removing a board or device, the fault has occurred there.
4. The replacement method requires two instruments of the same model or sufficient spare parts. Replace a good spare with the same component on the faulty machine to see if the fault is eliminated.
5. The comparison method requires two instruments of the same type, and one of them is in normal operation. Use this method to have the necessary equipment, such as a multimeter, oscilloscope, etc. According to the nature of the comparison, voltage comparison, waveform comparison, static impedance comparison, output comparison, current comparison, etc.
The specific method is: let the faulty meter and the normal meter run under the same conditions, and then detect the signals of some points and then compare the two sets of signals measured. If there are differences, it can be concluded that the fault is here. This method requires the maintenance personnel to have considerable knowledge and skills.
6. The temperature rise and fall method sometimes, the instrument works for a long time, or when the working environment temperature is high in the summer, there will be a fault, the shutdown check is normal, and the power is turned on again after a period of time, and the fault occurs after a while. This phenomenon is caused by the poor performance of individual ICs or components, and the high-temperature characteristic parameters fail to meet the requirements of the index. In order to find out the cause of the malfunction, the temperature rise and fall method can be employed
The so-called cooling, that is, when the fault occurs, use cotton fiber to wipe the anhydrous alcohol in the part that may be faulty, to cool it, and observe whether the fault is eliminated. The so-called heating is artificially raising the ambient temperature, such as using a soldering iron to close the suspected part (be careful not to raise the temperature too high to damage the normal device) to see if the fault occurs.
7, riding the shoulder method riding shoulder method is also called parallel method. Place a good IC chip on the chip to be inspected, or connect good components (resistance capacitors, diodes, transistors, etc.) in parallel with the components to be inspected, and keep in good contact. If the fault is caused by an open circuit inside the device or If the contact is bad, etc., this method can be used to eliminate it.
8. Capacitor Bypass Method When a circuit produces a strange phenomenon, such as when the display is disordered, the capacitor bypass method can be used to determine the part of the circuit that is likely to be faulty. Connect the capacitor across the power supply and ground of the IC; connect the transistor circuit across the base input or collector output to observe the effect on the fault. If the capacitor bypass input is inactive and bypasses its output, the fault disappears. By following the above steps on the magnetic flap level gauge , it is safer and more accurate when used! !
Geosynthetic Clay Liner is also named sodium bentonite composite waterproof pad. This is to make high swelling sodium bentonite filling into the inside between special composite geotextile and non-woven fabric. The bentonite impermeable cushion that made of acupuncture method can form a lot of small fiber spaces. This is to make the bentonite particles cannot flow in one direction. When encountering water, it can form uniformly high density colloidal waterproof layer in the pad, and effectively prevent water leakage. Geosynthetic clay liner is suitable for artificial lake water, landfill, underground garage, roof garden, pool, oil depot and chemicals yard.
