Use according to actual needs <br> <br> job site, determine where and how the lamp and the lamp from the power source to the contacts prepared Φ8 ~ Φ14mm three-core cable of appropriate length, through and into the three-core cable In a good steel pipe.
Loosen the compression nut of the lamp cable entry port (when it is shipped from the factory, it will not be used after the steel pipe is used). Introduce the power cable into the internal connection, fix the connection, and then tighten the cable cable and tighten the lamp cover. , Tighten the set screws.
When replacing the lamp, unscrew the Phillips pan head screw that holds the lamp ring and turn the lamp ring counterclockwise to separate the lamp ring and the transparent part from the housing. Take off the lamp and replace it with a new lamp. Install the lights.
caveat:
1. When installing and maintaining the lamp, the power must be cut off. 2, non-professionals are not free to install or disassemble lamps.
Precautions 1. When installing and maintaining the lamp, the power must be turned off.
2. When used, there is a certain temperature rise on the surface of the lamp, which is a normal phenomenon; the temperature of the center of the transparent part is high, and do not touch it.
3. When replacing the lamp, use the same type of lamp; if you change the lamp type or power, you should replace the ballast, capacitor and trigger accordingly.
BPC8720 explosion-proof platform lamp features:
â— Excellent explosion-proof performance, safe and reliable work in flammable and explosive dangerous places.
â—Using high-intensity discharge lamps as light source, high luminous efficiency, uniform illumination, and an average service life of more than 10,000 hours.
â— The shell is made of light alloy material and subjected to high-tech spraying treatment. It is wear-resistant, corrosion-resistant, waterproof and dustproof. Its delicate structure design expands the space for heat dissipation, reduces the temperature rise and improves the service life of the light source.
â— Small size, light weight, can use ceiling type, boom type, light pole type and other installation methods, the operation is simple and convenient.
â— Has good electromagnetic compatibility, will not cause interference to the surrounding environment.

This is about Centrifugal Fan
Centrifugal fan is to rely on the input of mechanical energy, increase gas pressure and send gas machine, it is a kind of driven fluid machinery. Centrifugal fans are widely used in ventilation, exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and draft in boilers and industrial furnaces; cooling in air conditioning and domestic appliances and Ventilation; grain drying and selection; wind tunnel source and hovercraft inflatable and propulsion.
Centrifugal fan works with turbine compressor basically the same, are due to the gas flow rate is low, little pressure change, generally do not need to consider the gas volume change, that is, the gas as incompressible fluid treatment.
Centrifugal fan can be made of right-handed and left-handed two types. Faced from the motor side: impeller clockwise rotation, known as the right rotary fan; impeller counterclockwise rotation, known as the left rotary fan.
Centrifugal fan from the chassis, spindle, impeller, bearing and motor drive and other components.
Chassis: made of steel sturdy and reliable, can be sub-integral and semi-open, semi-open for easy maintenance.
Impeller: the blade, curved front plate and plate rear plate composition.
Rotor: Static and dynamic balance should be done to ensure smooth rotation, good performance.
Transmission parts: a spindle, bearing boxes, rolling bearings and pulleys (or coupling) composition
Features
1. Compact structure: beautiful appearance, good stability, easy installation and maintenance.
2. Smooth operation: Optimized design of the impeller to reduce the axial force to a minimum, and efficient impeller, and static and dynamic balance correction, the machine running smoothly, without any damping device in the case of bearings Amplitude ≤0.04mm.
3. Low noise: blower operation, without any mechanical friction, the use of a reasonable blade-shaped line to the sound to a minimum. Centrifugal blower noise is high-frequency noise, as long as there are obstacles, can be noise, so the fan room almost no noise.
4. Oil-free machinery: Blower bearings with grease lubrication, bearing life of more than three years. Fan does not generate oil and gas during operation. Special requirements fans, with molybdenum disulfide lithium grease lubrication bearings.
5. Impeller: Impeller with a special compound linear, reducing internal leakage and improve the volumetric efficiency.
6 easy to adjust: the inlet valve to regulate flow, the outlet valve to regulate the pressure.
7. Drive: usually using a two-pole asynchronous motor, you can also use four-pole motor drive. Depending on the user grid, different voltage motors can be used.
8. Sealing: In addition to each level of import impeller impeller, the interstage and the housing at both ends with a labyrinth seal to prevent gas leaks.
9. Cooling: exhaust bearing housing has two structures, air-cooled and water-cooled, as the impeller on the level of gas compression, resulting in the exhaust casing temperature is much higher than the intake casing. In the exhaust bearing air-cooled or water-cooled device to extend the bearing life.
10. Bearing temperature control alarm: fan accessories with temperature control box, connected to the bearing through the PT100 resistance, when the bearing temperature exceeds the set temperature, the temperature control box will automatically alarm.
11. Transmission: a coupling drive, belt drive, gearbox drive three. According to different equipment and technology, choose a different transmission
