Does the car pass?
1. Is the vehicle detector wiring correct (1, 2 to 220V power supply; 7, 8 grounding inductance coil; 3, 4 connection gate main board signal interface);
2. When there is no car, the signal light of the vehicle detector will be on (it will indicate that the interference is felt when it is lit);
3. When the car is on the ground, the signal light of the vehicle detector will be on (not lit to indicate that no signal is detected, check whether the ground line is short-circuited);
4. After the car passes, the ground signal light is extinguished (not extinguished, indicating that the ground sense is disturbed);
5. Ungrounded, check whether the gate is up or down (determine whether the gate limit is normal);
6. When the rod is not in the horizontal position, short the connection line on the control panel of the gate, and see if the rod will rise and then fall.

Water treatment Filter Element is a filter element used for water treatment and liquid filtration. It is mainly used to remove suspended solids, sediment, rust and other impurities in water, and improve the cleanliness and transparency of water. The filter element is divided into the following types: PP filter element is also called PP melt-blown filter element, which is a filter element made of polypropylene material, which has good filtering effect and corrosion resistance, and can be used to purify tap water, groundwater, chemical liquids, etc.; The wound filter element is refined by finely winding textile fiber yarns with good filtration performance on a porous skeleton. The yarn materials include polypropylene fiber, acrylic fiber, absorbent cotton fiber, etc. By controlling the winding tightness and thinness of the yarn during winding, filter elements of different precision can be made, which can effectively remove suspended solids and particulate impurities in various liquids, and have a high purification effect on various liquids; folded filter elements , is a deep filter core folded structure, large membrane filtration area, large flux. Low differential pressure, strong dirt holding capacity and long service life. There are a variety of filter fineness to choose from, with a wide range of applications. Good chemical compatibility, suitable for filtering strong acids, strong alkalis and organic solvents. Processed and formed by hot-melt welding technology, does not contain any chemical adhesives, no leakage, no secondary pollution.
