brief introduction

Explosion-proof vortex pumps use flameproof enclosures to isolate electrical components that may generate sparks, arcs and dangerous temperatures from the surrounding explosive gas mixture. However, the enclosure is not hermetically sealed, and explosive gas mixtures from the surroundings can enter the interior of the motor through the gaps between the joint surfaces of the various parts of the enclosure. Explosion may occur when it comes into contact with ignition sources such as sparks, arcs, and dangerous high temperatures in the enclosure. At this time, the flameproof enclosure of the fan will not be damaged or deformed, and the explosive flame or hot gas will not ignite the surrounding explosive gas mixture when it is transmitted through the gap between the joint surfaces.

detailed introduction

Explosion-proof vortex air pump features:

1. Explosion-proof fan adopts new achievements of explosion-proof motor. When the supporting fan starts, the current is too large, which causes the fan to overheat and cause flammable and explosive gases to explode due to leakage. Explosion-proof fan is designed by regeneration principle. The single-chip centrifugal fan blade diameter is small, so that the air volume is increased. It produces high wind pressure characteristics and is maintenance-free! No oil! Long life! Efficient! Energy saving! Environmental protection and other characteristics.

2. Explosion-proof fan is compatible with the wind pressure and air volume characteristics of transparent fan, and any working condition except mining environment (anti-corrosion acid and alkali resistance can be sprayed with anti-corrosion paint inside and outside).

3. Explosion-proof fan except for explosion-proof junction box size change factors, other parts of the structure are with the turbine fan *, so can be arbitrarily installed, small size.

4. Explosion-proof fans are generally in line with Exd requirements due to the supporting explosion-proof motor of the insulation type, and the explosion-proof level is BT4/CT4.

Explosion-proof vortex air pump performance: 

1. It has dual functions of blowing and sucking, one machine has dual functions, it can be used for sucking air, and it can also be used for blowing;  

2, less oil or no oil operation, the output air is clean;  

3, relative to other fans, its pressure is much higher, often more than ten times that of ordinary fans;  

4, we explosion-proof blower overall die-casting, and the use of a shock-proof mounting foot, then it is also very low on the installation of the requirements, even without fixed foot can be normal operation, very convenient, but also very save installation costs and installation cycle; 

5. Compared with similar fans, the noise of its operation is lower.& nbsp; 

6, maintenance-free use; its wear and tear is only 1 bearing, within the warranty period, basically no maintenance is required;  

7, explosion-proof blower mechanical wear is very small, because in addition to bearings, no other mechanical contact parts, so, of course, the service life is very long.

8, the shell has all aluminum casting, equipped with * explosion-proof motor, fan installation is simple, easy to use!

Explosion-proof high-pressure blower uses:

Chemical industry, dust, methane transportation, boiler inflammable and explosive places, various mechanical equipment supporting, chemical plants, coal mines, tunnels, boilers, cans, glass industry, ventilation and exhaust, automatic cleaning, packaging, aeration, garbage decomposition, gas transportation, gas transportation, textile fabric dust collection, paper cutting cushion, sewage treatment, heavy oil spraying, gas station oil recovery, paper pulp dehydration, shuttleless loom, glass industry and ice factory air pump, tunnel engineering pressure air, Printing machinery, combustion machine, plastic extruder, bag blower, film coating machine, fruit making machinery, dust collector, environmental machinery, hot air generator, powder and particle conveyor, kitchen machinery, woodworking machinery, dryer, incinerator, thermostat, mechanical cooling, general air supply, etc.

Use and maintenance:

1, should be placed in a relatively stable place, the surrounding environment should be clean, dry, ventilated.

2. The impeller rotation direction must be the same as the arrow direction marked on the fan casing *.

3, when working, the working pressure shall not be greater than 8kPa, so as not to cause excessive heat and motor overcurrent caused by air pump damage.

4. Except for the two bearings of the motor rotor, there is no direct contact friction in other parts. The air pump bearing installation method is mainly divided into two categories. * The bearings at the end of the air pump are installed in the pump body between the motor base and the impeller. This type of air pump usually does not need to be greased. The bearings at the end of the second type of air pump are installed in the middle of the pump cover. The bearings at the end of this type of air pump should be regularly greased (7018 high speed grease). Once a month, the number of refuelling times should be increased for three consecutive shifts of air pumps. Maintenance of bearings at fan end of motor of this type of air pump is as follows: * Type of air pump.

5, the filter screen and muffler at both ends of the inlet and outlet should be cleaned in time according to the situation, so as not to block the use.

6. The external connection of the inlet and outlet port must be hose connection (such as rubber tube, plastic spring tube).

7, bearing replacement: bearing replacement must be carried out by a person familiar with the repair work. Loosen the screws on the pump cover first, and then disassemble the parts one by one according to the sequence shown in the figure. The removed parts should be cleaned, and then assembled in reverse order. When disassembling, do not pry the impeller hard, use Ramallah, and do not miss the adjusting gasket, so as not to affect the good clearance of the regulator when it leaves the factory.

8, explosion-proof vortex air pump is strictly prohibited solid, liquid and corrosive gas into the pump body.
