Intergrated Led Emergency Modules The Intergrated Led Emergency Modules is match the compact LED fittings to improve the emergency function. Normally it is workable for small wattage from 3-60W LED panels, downlights, led tubes, tri-proof ceilings. Full power output or half power emergency output is optional. Customized emergency lighting time is available. Automatic lighting up when main power failures. Widely using for home, parking lot, office, building, warehouse, school, hospital, workshop etc. Emergency Light Module,Emergency Led Flasher Module,Led Emergency Modules,Intergrated Led,led light with emergency battery Foshan Nai An Lighting Electric Co.,ltd , https://www.fsnaipsled.com
[Asia Fluid Network News] screw pump is self-priming pump equipment is relatively strong, it has the characteristics of low noise, high efficiency, long life, safe and reliable work. But when working, it also has a naughty side. Users are using such products, easy to meet the screw pump pressure is not enough, and the delay in the work, if you encounter pressure screw pump is not enough, how do we do? Next, for the majority of users to do a specific analysis: screw pump 1, the screw engagement was severely contaminated oil stains; 2, the active screw top round and driven screw root circle, driven screw outer circle with the active screw root circle The meshing gap of the thread; 3, the meshing gap between the active screw lug and the driven screw groove for the conjugate tooth profile meshing line increases due to the machining or use of the wear gap; 4, the three screw holes of the pump body wear out, Cylindrical fit gap increases due to wear and tear. Brush plating pump hole can be used to ensure that the outer screw and the pump body with the gap between the hole in the 0.03-0.05mm less than 5; pump body three-hole center deviation, so that the three screws in the pump body three holes Meshing in the asymmetric state, that is, while engaging tight, while engaging the loose, tight side of the engagement surface type, while the loose side of the leak was significantly increased. The three-hole pump center asymmetry should be within 0.02mm, and the pump body made of the active screw deviation (H7), the active screw cylindrical (g6) made under the deviation; 6, the main and driven cylindrical screw wear, With the pump three screw hole with the gap due to wear and increase. Brush plating screw can be used to ensure that the outer cylindrical screw with the pump body and the hole with the gap in the 0.03-0.05mm less; each product more or less has its deficiencies, many of these shortcomings Are solved by the way, as long as users are more careful and care. For the screw pump, the pressure may not work enough, this may occur for more than one reason, but to trace the traces of previous people, we still can find a lot of corresponding solutions. The use of products is similar to how people get along with people and requires constant interaction, and better results can only be achieved by working together.
