Shenzhen Dongxingyue Cooling Equipment Manufacturing low-noise axial flow exhaust fan, restaurant kitchen exhaust system King Centrifugal Fan, fire safety low-noise exhaust fan, medium and high pressure centrifugal fan and other high-tech products, the market applies to many fields such as restaurant kitchen, electronic device, plastic, chemical plant, ecological environment protection, industrial equipment and so on. First-class product quality and high-quality Technical Service has been the five-star praise of customers. Our enterprise fully automatic development, design, production and manufacture of famous brand smoke king has the advantages of large air volume, high air pressure, low noise and easy setting The key concentration in the hotel restaurant restaurant kitchen exhaust smoke difficult, building too high, pipe too long, too much elbow, underground smoke immediately. Have: wash-free, non-stick oil smoke exhaust effect is about 3 times the bellows, with the advantages of green environmental protection, one-shot deal with the smoke exhaust problems, the sales market recognition and comments. At this point, the blower static pressure is zero. The application scope is decided by the electric fan manufacturer. The total flow and working pressure of the electric fan can be obtained with satisfactory practical results. Typical Fan Applications: FRONT-CURVED SUCTION FAN: 30%-80% wocms; back-curved suction fan: 40%-85% wocms; axial suction fan: 35%-80% wocms. Radiator Fan mechanical equipment necessary: inverter power the original radiator fan design life from 25,000 hours to 40,000 hours, that is, continuous operation for 3 to 5 years otherwise, because the volume reduction of the INVERTER Or the frequent maintenance of electric fan rolling bearings, heat pipe cooling capacity reduced, resulting in more frequency converter damage, some customers can not choose to buy the market's high-volume fans, therefore, the use of cheap domestic small current fan to carry out the replacement, exhaust air volume is small, immediately damaged, resulting in the frequency converter service life is reduced, replacement should pay attention to the fan's current voltage and ventilation. Compared with the gear box of the blower motor below 2MW, the repair rate of the gear box of the blower motor about 2MW is about 4 times lower. According to the different model specifications, the Centrifugal Fan due to the common failure of the gearbox each year to stop the operation of the number of days in general account for the total number of 17-48% . Whether the ventilation system software can actually make harmful substances and environmental pollution in a room a problem will be solved, despite the lack of robust statistics However, the advantage of the ventilation equipment system software has to be admitted. There are various specifications and models to choose from. All the staff of Shenzhen Dongxingyue Technology Co. , Ltd. are unswervingly forging ahead with the strategic principle of being practical and innovative, being strict and harmonious Take quality as life, go all out to show economic development high-efficiency quality products and sound after-sales maintenance services. The other components of the fan, blades, transmission box, electric generator, rolling bearing and other core components are based on domestic production. With the development and design of Chinese companies Centrifugal Fan volume is growing, centrifugal fan control technology must be developed rapidly in order to meet the requirements. For example, the blade drive and control technology, more space inverter power development and design is always necessary to deal with the new issues. With the increasing proportion of wind turbines in China's power grid at the present stage, the problem of poor grid compatibility of wind power generation methods has gradually emerged In addition, customers are increasingly demanding Internet access requirements for fans of different wind farms and sizes, which has led to new daily tasks for automatic fan control systems Not only carbon dioxide gas, electric fans also have residual corrosion gas, with a variety of organic waste gas in the fan, at any time anywhere is accidental corrosion. Since there is essentially no raw material resistant to carbon dioxide and dry out of the Etch, checking for water mixing in poor operation must be done in a way that is immediately addressed. The working pressure is the key parameter of the high-pressure blower, there is no doubt that the working pressure and the temperature are closely related, the high-pressure blower changes the kinetic energy mode according to the working process, and therefore the speed ratio of the blower motor is also related Here's a first look at their connection. Working pressure of Blower Motor: 1 STATIC PRESSURE PS: Static pressure refers to the force released on the surface of the device and vertical to the surface. In blower motor, KGF M2 or mmaq is usually expressed according to the acting force and the push of the fan Can Be immediately measured and obtained. In the fan pipe, the static pressure value in any direction is constant, there are positive and negative points, static pressure value is normal when the pipe expansion, static pressure negative when the pipe compression. 2 DYNAMIC PRESSURE PV: Dynamic pressure refers to the velocity of fluid flow in the pipeline, the use of KGF / M2 or mmaq. 3 TOTAL PRESSURE PT: The so-called total pressure is static pressure and dynamic pressure, in the use of KGF / M2 or mmaq to express. The total pressure of the fan is fixed and will not be changed by the compression pipe of the pipe. D. C. Fan speed ratio control temperature adjustment fan principle is based on the heat around the fan to increase the speed ratio of the fan itself, in addition to increase the flow of gas. The temperature control fan uses an electric heating controller to check the temperature. The controller installed on the fan rim can check the temperature according to the fan. In this configuration, the fan must be installed correctly, and once the fan is installed, the heater can be guided by a special connecting wire. The higher the machining accuracy of the fan, the better the aerodynamic performance, and the sound level is lower than A. Generally, for the front-vane Centrifugal Fan, the rear-vane Centrifugal Fan with a sound level below 2DBA is lower than 38bBA for the blade centrifugal fan with a sound level below 30dBA and for the axial-flow fan with a blade below 25dBA. In different cases, the level of fan noise is determined by the following formula: La Lsa + 10LgQPdBA type: the Air Inlet or exhaust port of the Lablower, DBA; Control lsa-blower inlet or exhaust than a level, DBA q-wind capacity, m 3 / Min total pressure, mm water column. The general method of blower noise is to install resistance muffler at the inlet and outlet of blower http://www.dxymotors.com
