WQ sewage pump product range, reliable quality and reasonable price

A, WQ sewage pump sewage and sludge suitable for a variety of harsh environment of pumping row silt. Downdraft pump is capable of pumping out face surface water; submersible motor is a three-phase asynchronous motors: small footprint, easy to install, reliable and durable, long life. Environment and conditions 1, power frequency 50Hz, rated voltage of 380V or 660V (tolerance is: 5%) of the three-phase AC power source. Volume solids conveying medium than 2% or less, the transmission medium density up to 1.2x 103kg / m3. 3, since the transmission medium PH value of 4 to 10. 4, the transmission medium temperature does not exceed 40 ℃; the structural characteristics of 1, the next WQ series submersible sewage pump-priming by the submersible sewage pump three-phase asynchronous motors and two major components. The lower part of the pump motor is directly connected to its middle with a reliable mechanical seal device can effectively prevent the exchange between the cooling fluid within the electric motor and the pumped media, to ensure long-term reliable operation of the pump. 2, motor winding polyethylene waterproof nylon jacket wire, the motor cavity and sealing the cavity perfusion on the 10th or the 25th machinery oil transformer oil (expressed in vertical pumps submerged bearing limit can not be filled); motor using radial ball bearings, easy disassembly, easy maintenance. 3, low flow pump is a centrifugal or cyclone-type structure for pumping ordinary sewage, drainage engineering high-lift transport; large flow pump is a double channel non-blocking or Francis structure for coal washing waste water recycling, coal and pumping agricultural irrigation water; 4, pump designed to take into account the non-blocking this critical issue, the particles of impurities by good performance. 5, the motor housing is set up cooling jacket, the motor can work out of the water within a certain time; when pump structure of built-in structure, was sent to the liquid discharge through the motor, the motor portion may work long hours out of the water. 6, in order to prevent the motor cavity pressure caused by excessive casing burst in from the cover portion is provided with a pressure relief valve.
