BQW mining sewage pump sewage pump price

BQW mine sewage pump sewage pump price BQW Mine sewage pump from the motor, pump parts and sealed oil chamber composed of three parts. Motor flameproof structure, B-class insulation, winding the maximum allowable temperature of 130 ℃. Sealed oil chamber is located under the motor, the rotor shaft with a double-ended mechanical seal, the oil cavity note No. 10 oil, oil seal the side wall of the oil plug. Pump part of the impeller, pump body and water base, pump and motor coaxial, for the next pump structure. Electric pump motor part of the thermal protection device, exposed to the water, the temperature exceeds 75 ℃ automatically cut off the power to stop working, the pump automatically cooled to receive electricity work, effectively ensuring the life of submersible sewage pump. Pumps and has a small, compact, safe and reliable, movement, assembly and disassembly, easy maintenance, high efficiency, good performance, and low power consumption than comparable pumps. BQW (former BQK) coal mine explosion-proof submersible sewage pump for methane containing coal dust explosion dangerous places sewage water used, can be widely used in coal mine any operating surface, transport containing dirt, pulverized coal , Silt and other solid particles of groundwater. ■ Structural Features 1.BQW series suction built-in mine flameproof submersible pump, submersible explosion-proof three-phase asynchronous motor and sewage pump composed of two parts. The motor is directly connected with the pump body in the lower part of the motor. The middle part is provided with a reliable mechanical seal, which can effectively prevent the exchange between the coolant in the motor and the pumped medium. The cooling performance is good and the electric pump is ensured to operate reliably for a long time. 2 motor winding nylon waterproof polyethylene wire. Motor cavity and the seal perfusion mechanical oil No. 10 or 25 transformer oil (to vertical pump, submerged bearings on the limit, shall not fill); motor using radial ball axis, disassembly easy, easy maintenance; Small flow pump impeller is closed centrifugal structure for pumping mining excavation surface sewage, the central water storage high lift drainage: large flow pump impeller for the double flow passage without clogging or mixed flow structure for the mine with high impurity pumping . 4. Pump design fully considered the key issue without clogging, particle impurities through the good performance. 5. Electric pump structure is built-in, was pumping liquid discharged by the motor, the motor part of the surface can be exposed for a long time work. ■ Product Model Description: BQW □ □ □ │ │ │ │ │ └ ─ ─ ─ ─ ─ ─ Power kW │ │ │ │ └ ─ ─ ─ ─ ─ ─ ─ ─ Head m │ │ │ └ ─ ─ ─ ─ ─ ─ ─ ─ ─ ── flow m3 / h │ │ └──────────── sewage │ └────────────── diving └────────── ────── flameproof pump Jining City, mining machinery industry mainly produces mine with submersible pumps, pneumatic submersible pumps, spray pumps, BRW40,80,125 emulsion pump, mine resistance of the pump, note Pumps, sewage pumps, water centrifugal pumps.
