At present, many equipments are inseparable from the boot room, which provides us with convenience. At the same time, in the technical treatment of the decoration and renovation of the computer room, it is necessary to achieve dust prevention, energy saving, fire prevention, anti-static, waterproof, and rodent control. especially important. If the dust in the equipment room is not in place, even the best server and network equipment will fail. The customer service staff of the computer room air conditioning company will come to briefly introduce it to everyone.
Because servers and network equipment generate a lot of heat during operation, in order to dissipate the heat, the heat is usually dissipated by active heat dissipation, and due to the small space in the equipment room, these devices usually use the wind-ling method to dissipate heat. The holes cooperate with the convection air to bring dust into the equipment room. In addition, some equipment generates high voltage and static electricity during operation, which will attract dust in the air. Dust will carry moisture and corrosive substances into the device together, covering the electronic components, resulting in a decline in the heat dissipation capacity of the electronic components. Long-term accumulation of large amounts of heat will cause unstable operation of the device. In addition, because the dust contains moisture and corrosive substances, the insulation resistance between adjacent printed wires is reduced, or even a short circuit, which affects the normal operation of the circuit. Seriously, it will even burn out the power supply, motherboard and other equipment parts. When too much dry dust enters the equipment room, it will play an insulating role, which directly leads to poor contact between the connector contacts. At the same time, it will increase the frictional resistance of the action of the device, and the lighter will accelerate the wear of the device, and the heavy will directly cause the device to be stuck and damaged. It can be seen that dust is very harmful to the server. Therefore, dustproofing of the equipment room is particularly important and must be paid attention to.
1.In the maintenance process of the equipment room, the personnel entering and leaving will bring a part of the dust into the equipment room;
2. Dust generated by the equipment room itself or the aging of the equipment room may generate dust;
The importance of dust prevention in the equipment room and construction dust prevention measures
3. The air conditioning system used to maintain the temperature and humidity of the entire computer room environment will also bring a small amount of dust into the computer room;
4. There is negative pressure in the machine room, that is, the outside air pressure is greater than the machine room air pressure, so that the dust is squeezed into the machine room from the gap.
5. The decoration decoration of the enclosure structure of the equipment room, the choice of coating materials are improper, the weathering resistance is poor, and the wall, ceiling, ground and other parts are air-sinking and the coating falls off to generate dust.
1. Use dust-free decoration materials.
2. The air circulation area inside the ceiling and under the floor needs to be dust-proofed.
3. The air-conditioning and fresh air system should be filtered through two stages of primary effect and intermediate effect.
4. Maintain a certain positive pressure, so that the outdoor dust is not easy to enter the room.
5. Sealing measures should be taken for the joints and all holes of the machine room doors, windows, all pipelines passing through walls, etc.
6. Cover the equipment cabinet with cloth during the renovation and construction.
1. Regularly check the tightness of the equipment room.
Regularly check the doors and windows of the equipment room, clean the air conditioning filter system, close the gaps in contact with the outside world, eliminate the source of dust, and maintain the air in the equipment room clean.
2. Strictly control personnel access.
Set up an access control system to not allow people who are not allowed to enter the computer room to enter the computer room. The activities area of the personnel entering the computer room should also be strictly controlled to avoid entering the host area as much as possible.
3. Maintain the environmental humidity of the equipment room.
Strictly control the air humidity of the computer room, that is to ensure that the dust is reduced, and at the same time, avoid the corrosion and short circuit of the equipment when the air humidity is too high.
4. Partition control of computer room.
The importance of dust prevention in the equipment room and construction dust prevention measures
For large machine rooms, regional management should be carried out when conditions permit, and equipment that is susceptible to dust should be separated from personnel entering the machine room as much as possible to reduce their chances of contact with dust. For example, the computer room is divided into three areas, server host area, control area, and data processing terminal area. And set up a special visit channel, the channel and the host area are separated by a glass curtain wall.
5. Take precautionary measures against dust.
The machine room should be equipped with special work clothes and slippers, and be cleaned frequently. Personnel entering the equipment room, whether they are personnel of the equipment room or other persons allowed to enter the equipment room, must replace special slippers or use shoe covers. As few people as possible enter the equipment room wearing fiber or other clothing that is prone to static electricity and dust.
6. Increase the pressure in the equipment room.
It is recommended to use positive pressure dustproof in the equipment room with conditions, that is, to continuously input newly filtered air into the equipment room through the fresh air equipment in the equipment room to increase the air pressure inside the equipment room. Due to the pressure difference between the inside and outside of the machine room, the air in the machine room is vented out through the gaps of tightly closed windows and doors, so as to achieve the effect of dust prevention.
It is not enough to prevent dust in the equipment room. You must remove the dust regularly to ensure a dust-free environment.
1. Set a reasonable dust removal cycle
Set a reasonable dust removal cycle according to the specific conditions of the equipment room, and clean them separately according to the three parts of the interior of the equipment room, the exterior of the equipment room, and the interior of the equipment room
2. Beware of electrostatic hazards
When disassembling the machine to clean the equipment, we must first avoid the damage to the equipment caused by the live electricity. Before cleaning, wear anti-static clothes and anti-static ring equipment. To avoid disassembling the machine while it is powered on, it must be completely powered off and the server is well grounded, even for devices that support hot swapping to prevent damage to the device from static electricity. For display and other equipment, discharge treatment should be done first.
Daily dust and dust removal can ensure the dust-free environment of the computer room.In order to make the equipment room operate more efficiently, daily dustproofing of the computer room is essential.
Six, dustproof safety measures for equipment room equipment
A large number of servers, storage equipment, network equipment and other sophisticated high-end equipment are running in the communication equipment room. These equipment have high requirements for the cleanliness of the equipment room environment. Dust is a major hazard to the operation safety of network equipment. Network equipment, services, storage equipment and other electromechanical equipment will generate certain static and magnetic fields when working, plus the suction generated by the operation of the power supply and the fan will cause the dust particles suspended in the air to be sucked into the machine. The formation of electrostatic adsorption causes poor contact of metal connectors or metal contacts, reduced insulation performance, mildew, and poor heat dissipation, resulting in excessive temperature rise, which will not only affect the life of the equipment, but also cause failures. In order to ensure the normal operation of communication equipment, our construction personnel strictly implement the following points on dust prevention during construction:
1. The construction personnel wear clean and tidy work clothes to enter the machine room
2. Construction personnel enter the machine room with shoe covers to prevent dust from being brought into the machine room.
3. The equipment cabinet and ground must be covered with dustproof felt cloth to prevent dust from entering the equipment.
4. The construction personnel should take it lightly when dismantling the construction to prevent the generation of dust, and pay attention not to touch the original cable.
5. When using an electric drill or other tools for drilling in the machine room, you must use a vacuum cleaner to prevent dust from being generated.
6. After the construction is completed, use a damp cloth to gently wipe off the dust generated during the construction process. It is strictly prohibited to clean it with a broom to avoid dust.
7. When unpacking construction materials, it must be carried out outside the machine room, and it is strictly prohibited to stack them in the machine room.
8. Every time the personnel leave the site, the clearance is completed, on the corridor and in the compound. At the end of the day, the site must be cleaned until it meets the hygienic requirements of the computer room.
