1 Explosion-proof air-conditioning installation unqualified maintenance is not timely Air-conditioning installation does not meet the regulations prone to accidents such as air-conditioners and other electrical equipment, metal housing is not grounded device, although there is a grounding device, but the power is too thick or the grounding wire and terminal does not have to be fastened Connection or welding as a whole arbitrarily change the power cord, wiring or insulated conductors Broken air conditioners live parts exposed Use unqualified electrical products, (such as online socket) to install The installer is not a professional electrician or lack of electrical safety knowledge Do not understand electrical Installation of technical requirements, etc. result in poor installation quality. Maintenance and repair are unfavorable, resulting in stability or risk of electric shock.
Electrical equipment, including line air conditioner switches, sockets, etc., will be used for a long time. Insulation aging failure or even component damage will result in accidents if they are not repaired or replaced in time.
2 During work, an electrician with poor safety consciousness is paralyzed at work. The electrician is paralysed and lacks strong sense of responsibility. He does not strictly observe safety procedures and causes electric shock. For example, when a device such as a line or an air conditioner works, it is repaired or repaired when the air conditioner is repaired. Seeing that the power supply lamp of the air conditioner is off, it is thought that there is a power failure and there will be electric shock accidents during the repair. According to the explosion-proof air conditioner, the explosion-proof air conditioner is slightly different from the ordinary air-conditioner, and the explosion-proof air conditioner is modified and explosion-proof on the original model. Explosion-proof air conditioners need to determine where the air-conditioner moves before the machine is disassembled, and whether the length of the pipe is sufficient. Whether the location of the air conditioner is suitable or not meets various requirements. The relocation of air conditioners also needs to meet the requirements for general installation of air conditioning locations. It is necessary to investigate whether the location of the environment is suitable for the transfer of air-conditioning and prepare the necessary materials and equipment.
Explosion-proof split air-conditioning shift machine dismantling, the standard operation is very important, if the dismantling operation is not standardized, it will lead to leakage of snow, copper joints damaged, broken copper, etc., after the transfer of the explosion-proof air conditioning performance is very Great influence.
Disassemble the general process steps <br> <br> first partial air conditioner outdoor liquid pipe (Flanagan thin brass) copper unscrew the cap off valves, with a hex wrench clockwise valve closed. Let explosion-proof air-conditioning cooling run for about 5 minutes (cooling temperature as low as possible to ensure that the compressor turns up, the purpose is to return the refrigerant in the indoor unit and the two copper tubes to the outdoor unit), hand touch the outdoor unit The temperature of the two copper pipes next to the valve, after the copper pipe has no feeling of coldness (indicating that the refrigerant has been recovered), closes the valve of the gas pipe (thick copper pipe) and closes (pulls out the power plug) in the same way. Then remove the outdoor unit electrical connection. Open the two brass joints and pull the straight copper pipe under the control. One person pulls the lower part of the indoor hook up against the wall and lifts it upwards. The other pulls the outdoor copper pipe through the hole in the wall (pay attention to safety. As long as the cabinet can be removed directly). After the indoor unit is removed, straighten the copper pipe and turn it to the big bend for handling (be careful of the copper pipe bending). Take down the indoor machine hanging plate, remove the outdoor machine foot screws (such as high altitude should pay attention to safety, the two valve ports should be bandaged, to prevent impurities and moisture into), and finally remove the outdoor machine mounting bracket.
Explosion-proof air-conditioning and ordinary household air-conditioning has a subtle difference, in some aspects can not be operated in accordance with the ordinary air-conditioning maintenance after-sales service, if the user does not understand the place does not understand, remember not to unauthorized disassembly and maintenance of explosion-proof air-conditioning, safety , make full preparations for safety.

This kind of glass beads are processed from special glass raw-materials. The refractive index is between 1.57 and 1.60. Its` reflective performance is superior to those glass beads adopted from architectural glass with same roundness and particle size. And the roundness and particle size can be customized according to requirements.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
