Xiamen, million liters Electrical Equipment Co., Ltd. was established in 2006 to stop procurement of marketing model to serve our customers. The company currently has four chain stores, Xiamen caster, shopping malls mainly wholesale - wire and cable, labor supplies, industrial casters, packaging materials, transportation equipment, abrasive abrasive, hardware tools, power tools, lifting spreader, fans Fans, handling equipment and other types of enterprise, has the advantage of cheap, uphold the real cost savings for the customer service and the concept of business development for the majority of manufacturers to provide strong support. Centrifugal fans is to rely on the input of mechanical energy, increase the gas pressure of the gas sent to the mechanical side, which is a slave fluid machine. Centrifugal fans are widely used in factories, ventilation mines, tunnels, cooling towers, vehicles, ships and buildings, dust emission and cooling; boiler and industrial furnace ventilation and the air; air-conditioning equipment and household appliances cooling and ventilation; grain drying and should select; wind tunnel inflatable air source and hovercraft and propulsion. Centrifugal fan [1] is based on the principle of potential energy is converted to kinetic energy, Xiamen caster Which is good, using high-speed rotation of the impeller the gas to accelerate, Xiamen caster factory, then slow down, change the flow of the kinetic energy into potential energy (pressure ). In the single-stage centrifugal fan, the gas enters the impeller in the axial direction, changing the gas flow through a radial impeller, and then into the diffuser. In the diffuser, the gas flow direction changes cause deceleration that the deceleration effect the kinetic energy is converted into pressure energy. Pressure increased mainly in impeller, diffuser happens next in the process. In the multi-stage centrifugal fan, the reflux stream allows the impeller to the next, resulting in a higher pressure. Xiamen, million liters Electrical Equipment Co., Ltd. was established in 2006 to stop procurement of marketing model to serve our customers. The company currently has four chain stores, shopping malls mainly wholesale - wire and cable, labor supplies, industrial casters, packaging materials, transportation equipment, abrasive abrasive, hardware tools, power tools, lifting spreader, Blowers, handling equipment and other all types of enterprise, has the advantage of cheap, uphold the real cost savings for the customer service and the concept of business development for the majority of manufacturers to provide strong support. Axial fan is driven by the motor running, in fact, are the same for any equipment, you want to run up and must have a similar "engine." In the choice of axial fan motors, hoping the motor drives the impeller can quickly reach the rated speed and is working. Motor starting include energizing the whole process of starting and acceleration. Its start-up mode into full voltage starting and decompression starter. A reasonable choice of motor starting methods, must be based on the capacity of the power supply network, the mechanical load on the starting torque requirements, the characteristics of the motor itself and other factors, specific analysis, in order to obtain a predetermined start-up time. For example, the capacity of the power grid of large motor starting current in the power line does not cause a significant voltage drop, in addition, the grid control lines and equipment allow short by a sufficiently large starting current, Xiamen caster company phone, you can with full pressure start; torque at the start if the fan is not required, and in terms of network capacity is not large relative to the motor, the main consideration is how to reduce the starting current and start using decompression. Xiamen caster factory, Shenzhen blower fan distribution, Xiamen, Xiamen caster million liters provided by the Electrical and Mechanical Equipment Co., Xiamen, million liters Electrical Equipment Co., Ltd. (www.xmlysjd.com) is a leader in Xiamen, electronics, electrical products manufacturing equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. One hundred million liters in the United Electromechanical leadership with the staff warmly welcome all inquiries negotiations to create one hundred million liters associated electromechanical better future.
