Introduction

An overview,
Developed by our company BQS series sand mining flame-proof row of submersible pumps, is suitable for the air containing gas and other explosive gases used in dangerous places, including coal mining face roadway, bottom hole water nest, the water, warehouse, etc., can be to contain coal, sediment, stone powder, such as sewage containing solid particles, can also be used for engineering disaster, mine bottom permeable zone and rivers and the sea area of water, flow from after 15 m/h to 1000 m after/h, lift from 24 m to 1000 m, flame-proof motor power from 20 kw to 1150 kw, is easy to install and use, flame-proof characteristics such as reliable and durable.
Second, explosion-proof grades and standards
1. The BQS series of mining flame-proof diving desilting electric pump for explosion-proof type flameproof, the explosion-proof marks for "ExdI".
2. Electric pump standards for Q, 140727 SXTB005-2006 "trapping by the mining flameproof submersible pumps, and MT/T671-2005 with the coal mine flameproof submersible pumps,
Three, use of the environment and working conditions
1, power frequency 50 hz, rated voltage 380 v / 660 v, 660 v / 1140 v, 3000 v, 6000 v (tolerance of + / - 5%) of the three ac power.
2, the content of solid particles in water by less than 2% (volume ratio), particle size of no more than 3 mm.
3, pumping medium density is less than 1.2 x after 10 kg/m after.
4, pumping medium temperature does not exceed 40 ℃ (medium temperature more than 40 ℃ to special order).
5, medium pH value in the range of 6 ~ 9.
6 0 ~ 40 ℃, working environment temperature.
7, inlet submerged (submerge depth is not more than 70 m), but not buy and sediment in the motor.
Four, structure features
1, BQS series of mining flame-proof diving and sand pumps by the pump body and YBQS water filling type mine flameproof submersible motor, electric pump connection using the pump.
2, the BQS series of mining flame-proof diving and sand pumps (hereinafter referred to as the electric pump) installations can be vertical, horizontal, oblique type.
3, type motor for YBQS mining flameproof submersible pump motor, as the filling water wet, winding line adopts water resistant nylon sheathed electromagnetic wire, the motor chamber filled with pure water, cooling motor, guarantee the electric pump long-term reliable operation.
4, the motor shaft seal body adopts mechanical seal and framework oil seal, can effectively prevent the motor cooling fluid exchange with the outside media.
5, reclining installation, when using pumps straight league one after using the same base positioning installation, guarantee the alignment of electric pump, improve the reliability of the operation.
6, according to the needs of application, the electric pump shell, set up necessary cooling jackets, can make the motor fully cooling heating parts, prolong the service life of the motor.
7, the pump body part material selects the wear resistance of high strength material, can be used according to different occasions to adjust the needed materials, including corrosion of stainless steel pumps.
8, the protection type electric pump for GB/T4942.1-2000 rules "IPX8"
9, pumps do not need to add any mineral oil in use process, the unit itself can effectively protect the water quality.
