BQS series explosion-proof submersible sand discharge electric pump for coal mine is a drainage equipment that combines the pump and the motor, and the pump is located at the lower part of the motor. It has the characteristics of small size, light weight and good drainage effect. It is widely used in the automatic drainage of vertical shafts, inclined shafts and loose slime at the bottom of coal mines.

The flow rate is 10---500m h, and the head is 7---300m.

B is explosion-proof, Q is a submersible pump, and S is a safe use in the coal mine.

The main purpose of mine flameproof submersible pump.

a.Construction drainage of vertical shafts and inclined shafts in coal mines.

b.Drainage from the bottom of the mine without water silos.

c.Drainage of the excavation face.

d.Drainage of loose coal bunkers at the bottom of vertical shafts.

e.Clean up the silt and sediment drainage in the water tank.

f.Old ponds, no man's land gushing water drainage.

g.Other ** gas environment drainage.

h.Emergency rescue and disaster relief.

First, the use and characteristics:

BQS mine flameproof submersible sewage pump is an explosion-proof submersible motor and centrifugal pump coaxial direct connection of the external electric pump, the use of down-suction structure is an advanced and reliable drainage tool, the product through the national coal industry Shanghai Electric explosion-proof inspection station strict inspection, in line with the Q H001-2004 standard provisions, access to the explosion-proof certificate and mining product safety mark MA. It is suitable for use in the environment containing methane or coal dust ** gas mixture in the underground roadway and mining face or other surrounding media and other explosion-proof places.

BQS Mine Explosion-proof Submersible Pump Features:

1.Mine flameproof, compact structure, light weight, very suitable for mine handling and installation;

2.The whole unit is submerged in the water to work, and there is no need to build a pump room, which reduces the installation cost;

3.There is no need to pour water when starting, and it can be started instantaneously;

4.Compared with the non-submersible pump unit, it has the characteristics of not being afraid of flooding;

5.Low operating noise and low vibration;

6.Double-ended sealed, durable, safe and reliable.

2. Conditions for the use of BQS mine flameproof submersible pumps:

The flow rate of the outlet of the electric pump shall not be greater than the rated value (used within the specified head);

Pumping light sewage with a volume ratio of no more than 2% of clean water or solid impurities;

The diving depth does not exceed 5m;

The water temperature does not exceed +40 ;

The pH of the pumped liquid is between 5-9.

BQS explosion-proof submersible pump is suitable for places where there is a danger of environmental protection alkane and coal dust in coal mines, and conveys mixed sewage containing insoluble solids such as sediment, coal slime, coal gangue, cinder, and fiber. It can also be used for the discharge of waste water containing solid particles and long fibers, rainwater, and mine explosion-proof sewage discharge and sand discharge submersible electric pump sewage in buildings, hospitals, residential quarters, municipal engineering, road traffic and construction, factory sewage, small sewage treatment, etc. Built-in electric pump, water flows through the motor interlayer, which effectively prolongs the service life of the electric pump; The externally mounted electric pump, the impeller adopts a double-channel large overflow structure, which has the characteristics of stable operation, strong sewage discharge capacity, anti-winding, no clogging, and small size, light weight and easy to carry.

Working conditions of BQS mine flameproof submersible pumps.

1. The maximum diving depth should not exceed 5m, and the minimum depth should be so that the water inlet section (below the flange of the outer cover) should be submerged in the water.

2. The pH value in the water is 4 10.

3. The water temperature is not higher than kate00540.

4. The working mode is continuous work system.

BQS mine flameproof submersible pump product use.

1. Construction drainage of coal vertical shafts and inclined shafts.

2. Drainage at the bottom of the mine without water silos.

3. Drainage of the mining face.

4. Drainage of loose coal bunker at the bottom of the vertical shaft.

5. Clean up the silt and sediment drainage in the water tank.

6. Water gushing and drainage in old ponds and uninhabited areas.

7. Drainage of petroleum, chemical and other high-quality gas environments.

8. Rescue and disaster relief drainage.
