Quotation for explosion-proof medium pressure fan in coal mine underground

FX-1/2-0.37kw explosion-proof medium pressure fan

The explosion-proof marks of the explosion-proof medium pressure fan are CT4, dI, dIIAT4, dIIBT4, which are respectively applicable to fixed equipment in coal mines or factories with IIA and IIB levels, and to places where combustible gases or vapors form explosive mixtures with air in temperature groups T1-T4; The protection level of the main body shell is IP44, which can also be made into IP% 4, and the protection level of the junction box is IP54; The rated frequency is 50Hz, and the rated voltage is 380/660, 660/140V;

Features of EX explosion-proof fan: stable flow, high efficiency, low energy consumption: Under previous design and strict quality control, the fan has the following characteristics. Low energy consumption: Therefore, any method such as blowing, spraying, and suction has its effectiveness, and it has a relatively conservative design in the high-pressure range. When the usage situation changes, the full fan can still operate safely. Easy to install: can be installed at any time in the place of use for compressed air or for vacuuming. And it can be installed in any horizontal or vertical direction. High reliability: Apart from the impeller, there are no other moving parts, and the impeller is directly connected to the motor without gears or transmission belts, so it has high reliability and is free of charge. Low vibration: The mechanical density is high, and the other components of the rotating part have undergone extremely dense balance design, testing, and calibration, so the vibration rate is very low. Space saving - sturdy design reduces space waste. With over 30 years of manufacturing experience and rigorous quality control, all parts meet the requirements. At the same time, to ensure that every wind turbine is tested for operation before leaving the factory.

Medium pressure explosion-proof blowers are widely used in transportation, oil and gas, underground coal mines, paper cutters, combustion oxygen reducers, cigarette filter forming machines, electroplating tank mixing, atomization drying machines, water treatment aeration, aquaculture, screen printing machines, photographic plate making machines, injection molding machines, automatic feeding drying machines, liquid filling machines, powder filling machines, welding equipment, film machinery, paper transportation, dry cleaning, cleaning purposes, air dust removal, dry bottles, gas transmission, feeding, collection, water treatment, central dust collection environmental protection, aquaculture, screen printing brushes, electroplating, dust removal, food, packaging, filling, glass products, airflow transportation and other industries.

Explosion proof blower is suitable for places where explosive gas mixtures exist:

The Ex -- DIICT4-- DIIBT4 series explosion-proof fan is suitable for non mining working face environments in coal mines where explosive mixtures of methane or coal dust are present.
Ex-DIICT4 is suitable for use in factory environments with Class II *, temperature groups T1, T2, T3, and T4, where explosive gas dust mixtures are present.
Ex-DIIBT4 is suitable for use in factory environments with Class II, Class B, temperature groups T1, T2, T3, and T4 explosive gas mixtures.
On the basis of the EX-2 basic series electric fan, it can also be made into EX-G outdoor type, EX-Z outdoor medium anti-corrosion type and other climate environments.
The series of variable frequency high-voltage explosion-proof fans has three control modes: local, remote, and upper level. Different control modes can be freely switched, and users can choose according to their on-site needs. Under normal ventilation conditions, the frequency converter can be set to remote control or upper control mode for monitoring in the central control room; When on-site operation of the frequency converter and system debugging are required, local operation of the frequency converter is generally required. In this case, the frequency converter can be selected as the local control mode, that is, the frequency converter can be directly operated on the human-machine interface of the frequency converter.
1. The frequency converter has a reverse function, and users can set relevant parameters according to on-site needs; When the frequency converter parameter allows for reverse operation, there is no need to perform hard wired phase modulation. Simply adjust the given frequency to a negative value and the motor will enter reverse mode. When a major accident such as a fire occurs underground, the mine fan can immediately enter reverse mode to prevent the disaster from spreading and protect personal safety.
2. The frequency converter has functions such as motor overcurrent, frequency converter current limiting, frequency converter overcurrent, input phase loss, output phase loss, overheating protection, overvoltage and undervoltage protection, leakage lockout protection, etc., which maximize the safety of the system itself and user equipment.High temperature and explosion-proof fan: The overall material is made of aluminum alloy, and the motor is an explosion-proof motor, which will never produce sparks due to friction, making it more reliable to use and better explosion-proof.
Safety precautions: Normal temperature fans are allowed to have an inlet temperature of 40 degrees Celsius or above, and all models can undergo insulation and anti-corrosion treatment. Due to the possibility of high pressure series fans generating temperatures up to 100 degrees during operation, it is recommended to avoid using them in locations where danger may occur due to temperature rise during selection and use.
The fan configuration is: all aluminum body fan blades equipped with professional explosion-proof motors;
The motor protection level is IP55, the insulation level is F, and the explosion-proof level is high DIIBT4
High voltage insulation fan is used in industry to ensure the normal operation of motors in high temperature environments. The fan adopts high-temperature resistant bearings and an H-pole motor to ensure motor operation. The motor shaft is lengthened and a cooling fan is added to the shaft to ensure temperature transmission to the motor. Therefore, the fan can withstand a temperature of 260 degrees Celsius and operate normally with guaranteed quality.
