2.2KW submersible pump sewage sediment lowest shelf free trial long warranty Company: Jining annual Run Pump Co. Products BQS (W) flameproof sewage sediment submersible pumps, pump and motor combination is one of the power irrigation equipment, appearance, simple structure, good sealing performance, stable performance, long life, easy to install, and can be long-term continuous operation under water, are widely used in coal mine shaft, inclined and bottom of the bulk slime automated drainage. Built-in electric pump, water flowing from the motor sandwich, effectively extending the life of the pump; externally mounted pumps, impeller flow greater than dual channel structure, stable operation, sewage capacity, anti-winding, no clogging, and small size, light weight, portable and convenient features. Structural features BQS (W) series of flameproof submersible pump sewage sediment strictly according to the coal industry standard MT / T671-2005 "coal mine explosion-proof submersible pump," the names of the Republic of China national performance standards GB3836-2000 " Electrical apparatus for explosive gas atmospheres "design, motor using Y-dry flameproof three-phase asynchronous motor with starting torque, good operating performance, low noise, small size, light weight, easy maintenance, etc., as well as excellent flameproof structural performance and a higher level of protection for containing methane or coal dust and other explosive atmosphere, there is a risk of explosion under mine roadway excavation face and other places and supporting the use of pumps. Pump uses rubber O rings as static sealing, good structural performance, the use of rubber vulcanization curve control technology guarantees the quality and performance of the O-ring seal resistant to moisture aging of. Dynamic seal with two mechanical seals and oil chamber isolation protection, effectively providing lubrication for rotational friction, forming a fluid film lubrication protection, while the release of heat accumulation during exercise, thus extending the service life of mechanical seals to ensure the sealing performance. Fluid pump components are made of wear-resistant alloy cast iron, pump part is fluid mechanical design and balancing technology, effectively extending the life of the pump. Uses containing methane or coal dust explosion hazard of coal mine drainage mining face in coal mine shaft, inclined shaft construction of drainage water storage and drainage Main Shaft Bottom bottom of the main bulk coal bunker automatic drain the old pond, no man's land gushing automatic drainage coal mine groundwater discharge water drainage relief and rescue barn drainage systems urban environment contains coal dust, sand and other solid particles smaller sewage treatment conditions transport medium temperature should not exceed medium containing solid particles of 40 ℃, the volume concentration is generally not more than 2 % transmission medium pH in the range of 4 to 10 Working temperature 0 ~ 40 ℃ water pump sneak depth does not exceed 5m solid medium grain diameter of not more than the maximum pump flow channel flow cross-section of 50% minimum size of the basic parameters Model flow m3 / Yang Cheng kW h m power voltage V current A Rated speed r / min pump efficiency% Through the particle diameter mm 15-15-2.2 15 15 2.2 380 or 660 or 1140 or 2.98 5.12 33.3 3000 25 10 10 25-10-2.2 34.5 For recent domestic coal industry consolidation is very powerful, especially in Shanxi, the most important is for mine safety monitoring than it used to be a lot stricter, thus contributing to the mine for coal mine safety equipment needs to be much greater than in the past, the state coal mining enterprises worker safety issues make a lot of measures, but also led to other industries, the company produces a variety of pumps is one of mine safety equipment indispensable, I produced the pump certificate, quality assurance, good service, customers buy our products, if there are any questions, I would be the first time to resolve. Run Pump Co., Ltd. Jining in your purchase of the pump manufacturers assured.
