FBCZ 5.5-55KW 380-1140V Mine and tunnel flameproof type ground draw out type ventilator fan
Product Description
FBCZ series mine ground explosion-proof withdrawable axial flow fan is a new type of main fan with large air volume, low air pressure, high efficiency and energy saving. It is developed in combination with the ventilation network parameters of small and medium-sized coal mines. It can meet the ventilation requirements of small and medium-sized coal mines and large coal mines where multiple fans operate jointly. The machine has the characteristics of compact structure, high efficiency, remarkable energy-saving effect, low noise, good anti-wind performance, etc. It is an ideal ground main fan. The product is also suitable for metal mines, chemical mines, tunnels and other factories and mines where fans are used.

Technical parameters
Product features and Use environment
Structural features of fan:
(1) FBCZ series fan is composed of collector, host, diffuser and other components.
(2) FBCZ series fans adopt the direct connection mode of motor and impeller to reduce the loss of ventilation resistance such as "S" duct, improve efficiency, and reduce the potential safety hazards and maintenance caused by "S" duct
It is troublesome and improves the operation safety.
(3) The fan is equipped with a high-quality flameproof motor dedicated to the fan. The motor is placed in a flow separation chamber with a certain pressure resistance to isolate the motor from the mine and gas containing air flow. The flow separation chamber is equipped with an air duct for automatic ventilation with the atmosphere to facilitate heat dissipation and diversion. This not only increases the explosion-proof performance of the motor, but also facilitates the heat dissipation of the motor, thus increasing the safety of the fan operation.
(4) The rotating part of the fan impeller is equipped with a copper damage device to prevent friction sparks, so as to prevent the blade from colliding with the cylinder wall during high-speed rotation and causing accidents.
(5) The fan is equipped with non-stop oil filling device and oil drain device, which can fill lubricating oil during operation. When the fan is stopped, the oil drain cover can be opened to eliminate waste oil.
(6) A temperature measuring element is embedded between the bearing and stator winding of the motor, which can display the temperature of each part of the fan during operation.
(7) The wind blades are of twisted wing shape, with good aerodynamic performance, wide high efficiency area and remarkable energy-saving effect.
(8) The blade is an adjustable structure, and the blade angle can be adjusted according to different working conditions to keep the fan running in the high efficiency area.
Performance characteristics of fan:
(1) This series is an efficient, energy-saving, low-noise, large air volume ventilator.
(2) The hump area of this series of fans is narrow and the wind pressure is relatively stable, the air surge is weak, and the air flow is stable.
(3) This series of fans has a wide range of high efficiency areas, which can adapt to changes in mine production. When the ventilation parameters change, they still operate under a relatively stable condition.
(4) The fan adopts reverse reverse air, and the reverse air volume can reach 60% - 80% of the normal air volume.
Working conditions:
a) Ambient temperature: (-15~+40) ℃;
b) The altitude does not exceed 1000m;
c) The relative humidity does not exceed 90% (+25 ℃);
d) There is no strong vibration and corrosive gas, etc.;
e) Installed in fresh air flow underground in coal mines where there is a danger of methane and coal dust explosions. installed in the air intake duct
