1. In the engineering design, in order to facilitate the usual maintenance and management, the fire emergency lighting is preferably powered by a dedicated feeding automatic emergency lighting electric circuit.
2. In order to ensure the reliability of the fire emergency power supply, the condition should be powered by the low voltage emergency bus section of the substation. That is, when the diesel generator set is used as the emergency power supply, as long as the generator is put into use, it will continue to guarantee the electricity. powered by.
3. In the fire state, there is less smoke and more oxygen near the ground, and the instinct response of human evacuation is bending or squatting forward, so local high illumination illumination is more effective than uniform illumination brought by high position installation. Therefore, low-level installations should be promoted, that is, evacuation emergency lighting should be provided close to the ground or at ground level.
4. The emergency lights are delivered in the discharged state, and must be charged for 20 hours before use.
5, the emergency luminaires in use should be regularly checked for performance, every half month or month through continuous switch test to check the circuit conversion and battery emergency function, and discharge to extend battery life.
6. Do the fire protection of the distribution line. When it is darkly laid, it should be laid in the non-combustion structure. The thickness of the protective layer is not less than 30mm. When wearing the metal tube, wear the fireproof coating on the outside of the steel pipe or adopt other fire prevention measures. Use fireproof cables or fire resistant cables and wires.
Drilling Pressure Gauge
The drilling pressure gauge can accurately reflect the additional pressure from the driller weight and the bottom pressure at the time of pressure relief drilling during the drilling operation. It provides reliable base for acquiring reasonable drilling speed. It is suitable for use by drilling machines in the geological, metallurgy, oil, chemical and coal industry.
