3. When installing Type C and Type B, ensure that the two pulley positions are on the same plane, and the flatness tolerance is 0.5mm. 4. When installing Type D, use a dial indicator and feeler gauge to measure the coaxiality of the fan spindle and motor spindle and the parallelism of both ends of the coupling. The coaxiality tolerance of two shafts is 0.2mm, the parallelism tolerance of both ends of the coupling is 0.2mm, and the spacing between two planes of the coupling is 5 to 8mm. 5. After the fan is installed, move the rotor with hand or lever to check whether it is too tight or collided. The test run can be carried out without overtightening or collision. 6. After the motor is installed, the belt pulley or coupling guard shall be installed. If the air inlet is not connected to the air inlet pipe, the guard net or other safety devices (provided by the user) shall also be provided. 7. Other parts shall be installed according to the corresponding positions in the drawing. 8. Add N46 (ISO VG46, 30) in summer and N32 (ISO VG32, 20) in winter.

Yongzhou Wet electrostatic precipitator company The development trend and direction of wind turbine in the future are analyzed as follows: wind turbine is mainly used for ventilation and air exchange in various fields of national economy and various places, such as metallurgy, petrochemical, electric power, urban rail transit, textile, shipbuilding, etc. In addition to the traditional application fields, there will still be great development prospects in more than 20 potential market fields, such as comprehensive utilization of coal gangue, new dry process clinker technology, energy saving in metallurgical industry and comprehensive utilization of resources. large Wet electrostatic precipitator With the increasing competition in the wind turbine manufacturing industry, mergers and acquisitions and capital operations among large wind turbine manufacturing enterprises are becoming increasingly frequent. Domestic outstanding wind turbine manufacturing enterprises are increasingly paying attention to the research of the industry market, especially the in-depth research of the industry development environment and product buyers. Because of this, a large number of domestic excellent fan brands have risen rapidly and become the leaders in the fan manufacturing industry!

The use of wet electrostatic precipitators is becoming more and more common. How much do you know about the equipment? Today, I'm going to popularize knowledge for you and talk about the advantages and disadvantages of wet electrostatic precipitator. Let's learn together. Advantages of electrostatic precipitator High purification efficiency, capable of spreading fine particles of more than 0.01 microns. In the design, different operating parameters can be used to meet the required purification efficiency. ⑵ The resistance loss is small, generally below 20 mm water column. Compared with cyclone dust collector, the total power consumption is small even considering the power consumption of power supply unit and rapping mechanism. ⑶ Yongzhou Wet electrostatic precipitator The allowable operating temperature is high. For example, the allowable operating temperature of SHWB type circuit dust collector is 250 ℃. Other types can reach 350~400 ℃ or higher. ⑷ Large gas processing range. ⑸ large Wet electrostatic precipitator Automatic operation control can be fully realized. Disadvantages of electrostatic precipitator The equipment is relatively complex, requiring a high level of equipment allocation, installation and maintenance management. ⑵ There are certain requirements for the specific resistance of dust, so there is a certain selectivity for dust, which can not make all dust obtain high purification efficiency. ⑶ It is greatly affected by the operating conditions such as air temperature and temperature. If the same kind of dust is operated at different temperatures and humidities, the results will be different. Some dust can work well at a certain temperature and humidities, but the ESP can hardly be used at another temperature and humidities due to the change of dust resistance. ⑷ Wet electrostatic precipitator company The primary investment is large, and the horizontal electrostatic precipitator covers a large area. ⑸ At present, the practical effect in some enterprises can not meet the design requirements.

Preparations for fan installation. large Wet electrostatic precipitator 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. Yongzhou Wet electrostatic precipitator company 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 Wet electrostatic precipitator company 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、 large Wet electrostatic precipitator 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.

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.
