Before installation, first prepare the materials and tools for installation, and check the parts of the fan, especially the impeller, main shaft, bearing and other parts. If any damage is found, repair it, and then clean the inside of the bearing box with kerosene. In the process of installation, the following points must be paid attention to: 1. In order to prevent rust and reduce the difficulty of disassembly, some grease or machine oil should be coated on some joint surfaces. 2. When installing the bolts on the joint surface, if there are positioning pins, install the pins and tighten them before tightening the bolts. 3. Check that there should be no tools and sundries falling or left in the casing and other casings. Installed and used by CHANG factory bridge QIAO ISO9001 quality management system certification enterprise of Beijing No. 2 Blower Works 1. When installing the fan, the inlet and outlet must be provided with soft connection, and the weight of the gas transmission pipeline should not be added to the casing. Correct the gap size between the air inlet and the impeller according to the drawing, and keep the shaft in a horizontal position. 2. When installing the soft connection of the air inlet, the bolts of the air inlet itself can be directly used for connection. At this time, the air inlet is fixed by three countersunk screws.

major Axial flow centrifugal fan The wet electrostatic precipitator mainly has two structural forms. One is to use corrosion-resistant conductive materials (which can be non-metallic materials with excellent conductivity or metal materials with corrosion-resistant characteristics) as the dust collector, and the other is to use non-conductive non-metallic materials as the dust collector by forming a conductive water film through water spray or overflow. Wet electrostatic precipitators can also be divided into cross flow type (horizontal) and vertical flow type (vertical) according to the flow direction of waste gas. The cross flow type is mostly plate structure, city in Hunan Axial flow centrifugal fan The gas flows in and out in the horizontal direction, and the structure is similar to the dry electrostatic precipitator; The vertical flow type is mostly tubular structure, and the gas flow direction is vertical. Generally speaking, the efficiency of vertical flow wet electrostatic precipitator is twice as high as that of cross flow wet electrostatic precipitator under the condition of the same ventilation cross-sectional area. The dust deposited on the electrode plate can be washed down by water. Wet dust removal can avoid the re flying of captured dust and achieve high dust removal efficiency. Since there is no rapping device, the operation is also more reliable. The device that forms conductive film on the surface of the dust collector by means of water spray or overflow water has problems of corrosion, sludge and sewage treatment. It is only used when the dust concentration of the gas is low and the dust removal efficiency is required to be high; The wet electrostatic precipitator using corrosion-resistant conductive materials as dust collector does not need long-term water spraying or overflow water, Axial flow centrifugal fan Price Regular flushing is only carried out according to the operating conditions of the system, and only a small amount of water is consumed. This part of water can be recycled, and the dust collection system is basically free of secondary pollution.

Gas compression and gas transmission machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy and transports gas. The main structural components of the fan are impeller, casing, air inlet, support, motor, pulley, coupling, silencer, transmission parts (bearings), etc. major Axial flow centrifugal fan The unpowered fan uses the air thermal convection caused by the natural wind force and the indoor and outdoor temperature difference to drive the turbine to rotate, thus using the centrifugal force and negative pressure effect to exhaust the indoor stale hot air. city in Hunan Axial flow centrifugal fan Price The fan is related to the transmission and distribution energy consumption of the system, and is a very critical part of building energy conservation. According to the fan inspection conducted by the National Air Conditioning Equipment Quality Supervision and Inspection Center for many years, many fans have problems under rated conditions, so it is necessary to produce and manufacture fans in strict accordance with product standards. major Axial flow centrifugal fan At the beginning of the fan operation, the vibration of the bearing is very small, but with the extension of the operating time, the dust in the fan will be unevenly attached to the impeller, gradually destroying the dynamic balance of the fan, making the bearing vibration gradually increase. Once the vibration reaches the maximum allowable value of 11mm/s of the fan (the maximum allowable value expressed by the amplitude value is as follows), The fan must be shut down for repair (dust accumulation shall be removed and dynamic balance shall be redone). Because it is very dangerous at this time, users must not use it forcibly. When the fan vibration is close to the dangerous value, the vibration measuring instrument will give an alarm.

Preparations for fan installation. major Axial flow centrifugal fan Before unpacking the fan, check whether the package is intact, whether the nameplate parameters of the fan meet the requirements, and whether all accompanying accessories are complete. Carefully check whether the fan is deformed or damaged during transportation, whether the fasteners are loose or fall off, and whether the impeller is scratched, and check all parts of the fan. city in Hunan Axial flow centrifugal fan Price If any abnormality is found, it shall be repaired before use. Use a 500V megger to measure the insulation resistance between the fan housing and the motor winding. The value should be greater than 0.5 megohm. Otherwise, the motor winding should be dried. The temperature during drying should not exceed 120 ℃. Prepare various materials, tools and sites required for fan installation.

The wet electrostatic precipitator has been recognized by users due to many advantages in the process of application. It can remove dust and purify waste gas. It is an environmental protection equipment that can be used in a wide range of situations. What steps can we take when using this environmental protection equipment? today Axial flow centrifugal fan Price Let's take a detailed look. 1. First, close the power switch of the wet electrostatic precipitator. When the power indicator is on, the local remote switch will be switched to the local position; 2. Press the fan start button, and then observe whether the fan of the wet electrostatic precipitator rotates correctly. After the fan rotates normally, normal dedusting operation can be started; 3、 major Axial flow centrifugal fan After a period of time, if you need to clear and discharge the ash, you can press the ash cleaning button on the wet electrostatic precipitator; 4. Turn over the pulse valve to clear the ash, and the screw machine and ash discharge valve will also work together. The above is the whole content of the application process of the wet electrostatic precipitator. What we need to remind us here is that the equipment can be started only after the position is adjusted before it is used. During the dust removal process of the equipment, the humidification function can be started to keep the ground wet, so that the wet electrostatic precipitator can have a better application effect.

When the bearing temperature of the fan is normal, it is ≤ 70 ℃. If it rises to 70 ℃, an alarm should (will) be given if there is an electric control. At this time, the reason should be found out. First, check whether the cooling water is normal? Is the bearing oil level normal? If the cause cannot be found for a while, the bearing temperature rises rapidly to 90 ℃, and if there is an electric control, the alarm and shutdown signal shall be sent again. city in Hunan Axial flow centrifugal fan In the process of fan startup, shutdown or operation, if any abnormal phenomenon is found, it shall be checked immediately. If any small fault is found during the check, it shall be timely found out the cause and eliminated. In case of major fault (such as severe vibration, impact of fan, sharp rise of bearing temperature, etc.), stop the machine immediately for inspection. major Axial flow centrifugal fan The lubricating oil (or grease) shall be renewed and replaced one month after the first operation of the fan. In addition to replacement after each overhaul, the lubricating oil (or grease) can be replaced once every 1~2 months under normal conditions, or according to the actual situation. Fans include fans, turbine blowers, roots blowers and turbine compressors, which are divided into seven categories in detail, including centrifugal compressors, axial compressors, centrifugal blowers, roots blowers, centrifugal fans, axial fans and Ye's blowers
