DK40 fan

Resonance consequences DK40 fan. 1, the mechanical power source will pass through the fan and system 2, the pneumatic source to produce an impact load (load could cause the fan blade fatigue failure, especially in the high-pressure axial fans and centrifugal fans on) 3, DK40 fan surge caused by a wide range of 4 pressure changes, increased noise mine fan DK40-16 rotating floor fan Qian'an, fans are generally equipped with a dedicated fan starter, starter equipped way: star delta starter, auto step-down start, soft start and Frequency start. When equipped DK40 fan motor starters can protect, prevent motor overload, overheating, short circuit, phase, leakage and other protection needs, and to achieve the anti-wind turbine reverse, reverse air of not less than 60% full account of mine ventilation the requirements of a variety of factors, in line with the majority of mine ventilation needs. K / DK series fan of mine energy-saving features, the use of Chinese Academy of Sciences of the most advanced C-4 / II rows space twisted airfoil blades, according to "three-dimensional flow" theory of fan aerodynamic design, high aerodynamic efficiency and therefore, the host has a stable rings anti-surge device, at any mine resistance can be safe and stable operation, the motor and impeller Direct structure, easy maintenance, no danger of broken shaft, ground subsidence and minor slippage does not affect the normal operation of the fan. DK40 fan body using steel, steel welding structure, leaves a hollow steel material, the use of carbon steel petiole transfer of heat treatment, blade angle adjustable, high blade and the overall strength, resistance to shock wave of underground blasting ability, fans direct anti-wind anti-wind greater than 60%, without the construction of anti-duct can be installed on the surface, also suitable for installation in underground. Companies specializing in the production: FKZ fans, K, DK, JK main fan fan and fan FBD coal mine bureau fan pushed fan, FBDCZ (original BDK), FBCZ (former BK), FBDC coal mine main fan and other auxiliary Ventilator Bureau pumping gas blower fan, mine fan, mine fan, dust exhaust fan, high school low-pressure centrifugal fans, axial fans, centrifugal fans, induced draft fan, spray fan, gas pressure machine, corrosion fan, coal centrifugal fan, mining explosion-proof fans, roof fan, high temperature fan, exhaust fan fire, furnace blower, etc., and provide a wide range of standard and non-standard fan accessories, fan impeller blades, and provide on-site fan impeller balancing services. High quality and reasonable price, welcome new and old friends came to discuss the patrons.
