Mining MA high-pressure explosion-proof blower

Mining MA high-pressure explosion-proof blower
Mining MA high-pressure explosion-proof blower--Shanghai Liangjin Electromechanical Equipment Co., Ltd,High voltage explosion-proof blower is an explosion-proof vortex air pump used in flammable and explosive places. It adopts an explosion-proof shell to separate the electrical parts that may generate sparks, arcs, and dangerous temperatures from the surrounding explosive gas mixture, effectively preventing the occurrence of dangerous situations. It is mainly used for pressurized transportation of gas and marsh gas, and for use in flammable and explosive places.

Mining high-pressure explosion-proof blower explosion-proof blower process requirements
Explosion proof high-pressure fans are used in places with high concentrations of flammable gases that require ventilation, such as underground coal mines and boiler rooms for the transmission of flammable and explosive gases. The process requirements for explosion-proof vortex fans are that during the start-up and operation of the fan, sparks generated by the motor wiring terminals, stator and rotor, or other components should not come into contact with flammable and explosive gases from the outside, which may cause safety accidents. Rotating components will not generate sparks when they rub against the shell under special circumstances, in order to avoid causing serious consequences due to the formation of flammable gases. Of course, explosion-proof fans require explosion-proof motors to drive. The explosion-proof high-pressure fan has high mechanical precision, and the rotating parts have undergone extremely precise balance design, testing, and calibration, so the vibration rate is very low. It adopts a multi wing aluminum alloy heat dissipation shell with good heat dissipation, which can quickly dissipate heat and enhance the motor operation efficiency. The body and motor casing are cast separately. The fan impeller and shaft are sealed and dust-proof, which can prevent dust from entering and prolong the service life.

Construction of mining high-pressure explosion-proof blower and explosion-proof blower
Shell: Adopting a multi wing aluminum alloy heat dissipation shell with good heat dissipation, it can quickly dissipate heat to enhance the efficiency of motor operation. The high-pressure fan body and motor shell are separately cast; Motor: TEFC IP54F insulated motor. (According to European CE specifications);
Bearing: The impeller and shaft of the fan are designed with a sealed dust-proof feature to prevent dust from entering and extend their service life;
Impeller: A specially designed impeller with reduced gap range between the impeller and the body, which can prevent dust blockage during operation. Unlike other similar products with large corners and gaps, which can easily cause blockage and lead to high-pressure fan failure.

1. Shell material: Made of * degree die cast aluminum, which is the same aluminum material as Mercedes Benz wheel rims. Compared to ordinary aluminum alloys, die cast aluminum is stronger and has a more lightweight effect compared to iron shell fans.
2. Motor performance: Adopting a motor, the motor is a wide frequency, wide voltage motor, listed as single-phase 110V, 230V; Industrial three-phase 220V, 380V, 415V, 660V, etc. The motor frequency can be adjusted from 45-75HZ, with IP55 protection level and F-class insulation level. Its advantages are beyond the reach of domestic motors and are highly favored by domestic and foreign customers.
3. Fan oil seal: Made of high-temperature resistant material and fluororubber, it can withstand temperatures ranging from -25 ℃ to 300 ℃. Compared to the general oil seal, its lip temperature is 20-50 ℃ higher than the working medium temperature during operation, making it more stable in performance, maintenance free, and has a longer lifespan.
4. Fan bearings: The core components are made of high-quality branded bearings, which can withstand a temperature of 350 degrees Celsius and a speed of 4000 revolutions per minute. For ordinary performance bearings, they have stable performance, low noise, maintenance free, longer lifespan, and can ensure longer fan operation.

Mining high-pressure explosion-proof blower explosion-proof blower is made of aluminum alloy die-casting, sealed with high-strength sealant to seal the interface gap, with a spiral fan housing. At the same time, the explosion-proof fan is equipped with long-lasting lubricated bearings and high-quality oil seals to achieve a sealing effect. Explosion proof fan has stable performance, high pressure, strong vacuum degree, good sealing, no air leakage, no oil and gas, and has an explosion-proof certificate; Electric motor, safe and reliable, aluminum alloy casting; The output air is clean and has high accuracy; Small in size, the transported gas is oil-free and pollution-free.

Installation precautions for mining high-pressure explosion-proof blower and explosion-proof blower
1. Flat washers and spring washers must be used to tighten screws;
2. Can use rubber buffer to withstand the weight of high-pressure fans, especially high-power high-pressure fans, *;
3. For certain occasions where noise is required, a muffler can be installed to reduce noise (usually around 5dB). The muffler is installed at the end of the inlet or outlet duct;
4. For certain situations where high noise requirements are needed, a layer of soundproofing foam can be added based on the machine's own conditions to meet the on-site noise requirements. For specific details, please consult the noise control company of the high-pressure fan manufacturer;
5. When using sound-absorbing foam, pay attention to the distance between the high-pressure fan and the box, the ventilation and heat dissipation of the high-pressure fan, and the use of rubber buffer to bear the weight of the high-pressure fan. Please consult the manufacturer of the high-pressure fan for specific information;
6. The inlet and outlet pipes of high-pressure fans should be connected using hoses to isolate vibrations.
