High B4-72.B4-73.B4-79 centrifugal fan can be used as proof of flammable gas glow with ventilation efficiency, low noise; Specifications:: Explosion proof centrifugal blower fan Hao Yang detailed description of a total of 17 kinds of 2.8-12 , sub-type A type .C .D type wind capacity: 158000m3 / h, up to full pressure: 5200Pa; Explosion fan suitable transport flammable and non-corrosive gases, the ambient temperature must not exceed 60 ℃, widely used in general factory , warehouses, offices, residential ventilation or strong heating radiators, may also have a longer interval series exhaust pipe installation, in order to increase pressure in the pipe, do remove free fan motor. Explosion Francis fan oblique flow fan oblique flow fan for transporting flammable and explosive gas. Impeller made of machined from aluminum to prevent sparks during operation, the motor using flameproof motors. Fans need to stand with feet and motor voltage. Please specify when ordering. Centrifugal fan price explosion, explosion-proof centrifugal fan manufacturers, Texas proof centrifugal blower manufacturers, wucheng cheapest proof centrifugal blower manufacturers. Fan coil units, air, glass blower, air flow control valve, liquid thermostat efficient background noise mixed flow fan, Air Conditioning Equipment Co., Texas Hao Yang Francis fan, ramps flow fan bearing temperature exceeded, is one of the main bearing damage. Fan wheel manufacturers produce oblique flow fan price oblique flow fan, Texas Hao Yang specializing in the production of Francis turbine wheels, axial fan wheels, ramps flow fan wheels and centrifugal fan wheels. The main cause of the high bearing temperatures are the following: poor (1) lubrication quality. Lubrication aim is not to make direct contact with the movement part of the friction, and the formation of friction between solids and liquids. If the number of inadequate or poor quality lubricants, static and dynamic part of the direct causes friction and heat, or heat can not be taken away by the lubricating oil, leaving the bearing temperature. (2) poor quality of the rolling bearing assembly. Such as the inner sleeve and the shaft clamping force is not enough, jackets and bearing clearance is too large or too small. (3) bearing the quality is bad. Bearing scraping poor quality, Ugyen bad contact or bodiless; Rolling rolling decent cracks, chipping, peeling, etc., will undermine the stability and uniformity of the film, the surface of the bearing heat. (4) felt tight seal and heat. (5) bearing vibration is too large to withstand shock loads, seriously affect the stability of the lubricant film. (6) bearing cooling water shortage or interruption of mixed flow fan, with the influence of the heat, leaving the bearing temperature.
