Mining large explosion-proof submersible electric pump

SHENGYA Pump’s Strength and Industry Expertise：

Y(B)Q series submersible electric pumps have compact structure, small volume and light weight (pump and motor can be split for transportation and installation, high head pumps can also be segmented, easy to transport and install), pump effective area is wide, high efficiency.Y(B)Q series submersible electric pumps have a single suction (a suction port) and double suction (two suction ports) two types of pumps. There are two kinds of organization forms: upper pump and lower machine and upper machine and lower pump. It has low requirements for installation environment conditions, vertical, horizontal and inclined operation are available, and it is easy to be installed in vertical wells, inclined wells and water silos, and it can be placed in places suitable for drainage according to local conditions, with a wide range of applications and saving investment in civil construction.

Core Application Scenarios：

1.1 Underground Main Drainage System

Usage：As the “heart” of the mine drainage system, it is responsible for centrally and continuously discharging the water in the water silos at each level (middle section) to the surface. This is its core and most important duty, ensuring that the entire mine is not flooded.

Characteristics: The pumps used in this scenario are usually the most powerful, with the highest flow rate and head, and need to be extremely reliable and long-lasting in order to guarantee continuous production in the mine.

1.2 Underground local drainage or temporary drainage

Usage: set up at the digging face, the bottom of the mining area or other gushing water points, as the front stage or auxiliary of the main drainage system, firstly discharging the gushing water to the main silo, and then discharging it to the ground by the main drainage pump.

Characteristics: It may need stronger passing capacity (capable of pumping sewage containing a small amount of coal dust and rock chips) and is relatively flexible in installation and movement.

1.3 Emergency rescue and water control

Usage: used for emergency rescue and drainage when water surge, water penetration and other disaster accidents occur in the mine, it is the key equipment in the emergency rescue equipment arsenal of the mine. It can be quickly deployed to remove the surge water with maximum capacity and buy time for rescue.

Characteristics: Requires rapid startup and stable operation, and usually needs to have the characteristics of large flow and high head to cope with extreme situations.

1.4 Drainage for resumption of production in mines

Usage: After a mine stops production for maintenance or a long time due to an accident, a large amount of water will accumulate underground. Before resuming production, it is necessary to use large explosion-proof submersible electric pumps to carry out centralized and large-scale drainage operations to empty the underground water.
