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 Zunhua power tools, the mall major wholesale - wire and cable, labor supplies, industrial casters, packaging materials, transportation equipment, abrasive abrasive, hardware tools, power tools, lifting spreader, Fans & Blowers , 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. Fire-resistant cable refers to the combustion flame can maintain a certain time the safe operation of the cable. China's national standard GB12666.6 (et IEC331) the fire resistance test points A, B two classes, A grade flame temperature of 950 ~ 1000 ℃, continued for the fire time 90min, B grade flame temperature of 750 ~ 800 ℃, continued for the fire time 90 min Zunhua wholesale power tools, throughout the trial period, the specimen shall be subjected to the rated voltage specified product. Fire-resistant cables are widely used in places with fire safety and fire rescue-related high-rise buildings, underground railways, underground street, large power plants and major industrial and mining enterprises, such as fire-fighting equipment and emergency guide lights and other emergency facilities, power lines and control lines. 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. The main difference is that centrifugal fans and axial fans: Consolidated Atlas (2) 1, centrifugal fans changed the flow of the medium within the duct Zunhua power tools Which is good, but does not change the flow of axial fan duct inside the medium; 2, The former is more complex to install 3, the former motor and fan is usually driven by a belt connected to a rotating wheel, which is generally in the fan motor; 4, the former often install air conditioning units in the inlet and outlet of the boiler drum, induced draft fan, and so on. The latter were often installed in the duct or duct outlet front end. There are also mixed flow (Francis) fan, high pressure coefficient than the axial fan, flow coefficient than the centrifugal fan. To fill the gaps between the axial fans and centrifugal fans of. Along with easy installation features. Francis (or axial flow impulse) fan combines axial and centrifugal fans feature, although it looks more like a traditional axial fan. The curved plate-shaped blades welded to the conical steel hub. By changing the angle of the blades of the impeller housing upstream of the inlet to change the flow. The housing may have an open inlet, but more often the case, it has a curved rectangular shape, so that the motor can be placed outside the pipe. Excretion shell slow expansion to slow down the air or gas flow and convert kinetic energy into useful static pressure.
