Qiannan customized Boiler fan Installation requirements a. The foundation of the fan shall be level and solid, and the foundation height shall be ≥ 200mm. b. The fan and air duct shall be connected by flexible hose (flexible material and non combustible), the length shall not be less than 200mm, and the pipe diameter shall be the same as the inlet and outlet size of the fan. In order to ensure that the hose will not be twisted or deformed during the system operation, it should be installed with appropriate tightness. The canvas hose installed at the suction end of the fan can be slightly tightened to prevent the fan from being sucked in during operation and reduce the sectional size of the canvas hose. c、 Boiler fan Price The steel support of the fan must be fixed on the concrete foundation, and a rubber damping pad must be added between the steel support of the fan and the foundation. All fan and motor components are installed on the whole steel support, and the steel ground frame is installed on the damping pad at the top of the foundation. The damping pad is preferably made of perforated rubber plates. d. The pipe diameter at the outlet of the fan can only be increased, but not decreased. At the end of the outlet, an insect screen should be installed. When the fan is inclined to the upper outlet, a rain cap should be added

The wet electrostatic precipitator is mainly used to purify water vapor, odor, acid mist and other harmful substances in the exhaust gas discharged by the factory. As an air pollution control equipment, it has also been widely used. let's Boiler fan Price Understand its system composition together. 1. Composition of wet electrostatic precipitator system. According to its working principle, the control system of wet electrostatic precipitator generally includes high pressure system, water treatment system, low pressure heating and hot air purging system, upper computer system, etc. 2. Design of wet electrostatic precipitator system. (1) customized Boiler fan High voltage system and wet electrostatic precipitator charge the dust through corona discharge of high voltage system. The charged dust reaches the dust collecting plate under the effect of electric field force, and then the dust is removed by regular scouring. (2) Qiannan customized Boiler fan Water treatment system. This system deals with the problem of secondary water pollution. It is mainly the water discharged after equipment spraying and flushing, which contains a lot of acid substances and fine particles. Direct discharge will cause secondary pollution. The recycling of water in the equipment consists of two steps: neutralization and acid removal, and separation of suspended solids, so that the sewage can be turned into industrial water suitable for spraying. (3) Heating system. The heating system includes insulator incubator heating, hot air purging heating, and the hot air purging system is composed of fan, butterfly valve and heater. When it starts actively, it starts in the order of fan, butterfly valve and heater. When actively closing, it shall be closed in reverse order. (4) Upper computer system. The selected upper computer system is an industrial control computer, and the network front-end computer is used to enable the system to have extraordinary data acquisition and processing capabilities, so as to meet the requirements of wet electrostatic precipitator for centralized management, decentralized control, energy conservation and emission reduction.

How are dust collectors classified, customized Boiler fan Do you know how to distinguish it and how to define its economic type? Let's talk about it from these aspects. 1. Dust removal efficiency. Qiannan Boiler fan Dust removal efficiency refers to the ratio of the amount of dust collected by the dust collector to the amount of dust entering the dust collector. According to the total dedusting efficiency, the dedusters can be divided into: low efficiency dedusters (50~80%), medium efficiency dedusters (80~95%) and high efficiency dedusters (more than 95%). 2. Dust removal resistance. The resistance indicates the pressure loss when the airflow passes through the dust remover. According to the resistance, dust collectors can be divided into low resistance dust collectors (Δ P<500Pa), medium resistance dust collectors (Δ P=500 ～ 2000Pa) and high resistance dust collectors (Δ P=2000 ～ 20000Pa). 3. Economy. Economy is one of the important indexes for evaluating the dust collector, which includes the equipment cost and operation and maintenance cost of the dust collector. Among all kinds of dust collectors, the equipment cost of electrostatic precipitator is the highest, followed by bag type dust collector, Venturi tube dust collector, cyclone dust collector is the lowest electrostatic precipitator: the dust removal efficiency is high, generally above 99%, and the design efficiency is up to 99.99%. The wet dust collector is commonly known as "water dust collector" : The filtration efficiency can reach more than 85%, and the integrated desulfurization and dust remover of stone water film+swirl plate>>about 80% of desulfurization and dust removal can reach as high as about 95%.

Correct maintenance is an important guarantee for the safe and reliable operation of the fan and the improvement of its service life. Therefore, Boiler fan Price When using fans, full attention must be paid. Impeller maintenance: at the initial stage of impeller operation and during all regular inspections, whenever there is an opportunity, the impeller must be checked for cracks, wear, dust and other defects. The impeller must be kept clean whenever possible, customized Boiler fan The steel wire brush shall be used regularly to remove the dust and rust on the impeller. As the travel time increases, the dust can not be evenly attached to the impeller, which will cause damage to the balance of the impeller and even cause rotor vibration. As long as the impeller is repaired, it needs to be dynamically balanced again. If possible, the portable trial dynamic balancing instrument can be used for on-site balancing. Before dynamic balancing, check whether all fastening bolts are tightened. Since the impeller has been operating in an unbalanced state for a period of time, these bolts may have become loose. Bearing maintenance: frequently check the oil supply of bearing lubricating oil. If the box leaks oil, tighten the bolts of the end cover a little. If this is not enough, you may have to use new sealing packing. When the bearing lubricating oil is in normal use, it should be replaced at least once every six months. When it is used for the first time, it should be done after 200 hours of operation. The second oil change should be done in 1 to 2 months. After that, the lubricating oil should be checked once a week. If the lubricating oil does not deteriorate, the oil change can be extended to 2 to 4 months. The specified brand of lubricating oil (specified on the general drawing) must be used when replacing, The old oil in the oil tank shall be completely drained and cleaned before new oil can be filled. If the fan bearing needs to be replaced, pay attention to the following matters: before installing the new bearing, the bearing and bearing box must be very clean. Place the bearing in the oil with a temperature of about 70~80 ℃ and heat it before installing it on the shaft. Do not force assembly to avoid damaging the shaft. Maintenance of other supporting equipment: see the respective user manual for the maintenance of various supporting equipment, including motors, electric actuators, instruments, meters, etc. These operating instructions are provided by each supporting manufacturer. The manufacturer will pack these instructions together and provide them to the user

（2） Precautions for normal operation of fan 1. If the flow is found to be too large, which does not meet the operating requirements, or less flow is required in a short time, the throttling device can be used to adjust to meet the operating requirements. 2. The sensitivity of thermometer and oil pointer shall be checked regularly. 3. In case of any abnormal phenomenon during the start-up, shutdown or operation of the fan, it shall be checked in time. 4. For minor faults found in the inspection, find out the causes in time and try to eliminate or deal with them. If minor faults cannot be eliminated or major faults are found, repair them immediately. 5. In addition to replacing the lubricating oil during each maintenance, the lubricating oil shall also be replaced regularly. Observe the oil level at ordinary times and replenish lubricating oil in time.
