Submersible sewage pump BQW ore flameproof submersible the sewage pump BQW mine. Flameproof Product Introduction BQW (the original QBK) (series) Mine flameproof submersible sewage pump I plant engineering and technical personnel based on actual domestic coal mine drainage working condition, the technical characteristics of the the comprehensive QS-type water-filled submersible pumps and QBK-type desilting submersible pump, developed a new generation of high-reliability, high-life replacement products. Submersible sewage pump BQW mining flameproof the main purpose and the scope of the mine shaft and inclined construction drainage;, mine anhydrous positions in the bottom of the well drainage; submersible sewage pump BQW mining flameproof mining face drainage; 4 Shaft bottomhole bulk coal bunker drainage; 5, clean water positions sediment in drainage; 6, the old pond, no man's land Bay drainage; 7, petroleum, chemical explosive gas atmospheres drainage; 8, disaster relief. Working conditions, the maximum diving depth of no more than 5m, the minimum depth should make absorbent nets submerged; 2, the water temperature does not exceed 40 ° C water PH value within the range of 6.5-10; 4, the volume of water containing solid impurities than is generally not more than 2%; 5, water containing solid particles the size of no more than 10mm; altitude does not exceed 2000m; work environment 0-40 ° C; work for continuous duty. BQW series flameproof sewage desilting submersible pumps, power irrigation equipment is one of the pump and motor combination. The pump is located in the lower part of so called "downdraft", so to achieve the best effect of drainage. The pump my company to design new products, and a beautiful appearance, stable performance, and long-term continuous operation underwater. Submersible sewage pump BQW mining flameproof small size, light weight, simple structure, good sealing performance, easy to install, is a highly efficient, energy-saving new product. Submersible sewage pump BQW mining flameproof such pump using structure of mezzanine strong cold, long term dehydration running, so particularly suitable for coal mine methane (commonly known as gas) and coal dust explosion hazard BQW mining flameproof submersible sewage pumping mixed sewage containing silt, slime, coal gangue, coal cinder, and fiber material insoluble solid phase. Prepared at the request of the standard basis GB/T9969.1-1998 "industrial product use instructions General Provisions. Forthright with solid, Shandong Jining City Zhuoxin Mining Equipment Co., Ltd. adhering to visit our company, invited experts, leading, guiding, enlighten, and look forward to sincere cooperation with you, "the pursuit of excellence is always our theme, we will good governance and create efficient, and strive to the state-of-the-art technology, excellent product quality, provide multi-faceted services for coal mining enterprises. Product performance standards: the conditions of use of the MT / T 671-1997 Q / the the JAT 001-2006 BQW mine flameproof submersible sewage pumps Pump: 1, BQW mine flameproof submersible sewage pump power: frequency of 50Hz, three-phase AC power, rated voltage of 380V or 660V, to allow changes in the range of ± 5%. 2, the pump under the following conditions of use, can continuously operate normally. (1) The water temperature does not exceed +40 ℃. (2) The weight ratio of the water containing solid impurities does not exceed 2%. (3) water pH pH value of 5 to 9. (4) the basis of the center of the impeller, dive depth of not more than 5m. (5) The size should be consistent with the provisions of Q/JAT001-2006 water containing solid particles in a weight of water of not more than 11kN/m3. 3 BQW mining flameproof submersible sewage pump the surroundings: BQW mine flameproof submersible sewage pumps used in coal mine methane (commonly known as gas) and coal dust explosion hazard, conveying containing sediment, coal gangue, coal cinder, fiber matter insoluble solid phase mixed sewage contamination. Submersible sewage pump BQW mining flameproof Use and characteristics: BQW mine flameproof submersible sewage pump flameproof submersible motors and centrifugal pumps coaxial Direct composed externally mounted pump, BQW mining flameproof submersible sewage pump downdraft structure is an advanced and reliable tool drainage products by the State Coal Industry Inspection Station of Shanghai Electric Explosion rigorous testing provisions meet Q/HQQ001-2004 standard, proof certificate and mine with the product safety signs MA. Apply to underground mine workings and mining face or other surrounding medium in environments containing explosive gas mixtures of methane or coal dust explosion sites to use, with the following features: mine explosion-proof, compact structure, light weight, very suitable for mine handling and installation; dive work of the entire crew, construction of pumping stations do not have to reduce the cost of installation; startup without irrigation water can be instantaneous start; compared with non-submersible pump unit, not afraid of flooding the characteristics; running low noise, small vibration; Double end seals, durable, safe and reliable. B, BQW mine flameproof submersible sewage pumps conditions: electric pump outlet shall be not greater than the rated (specified head within); volume ratio of not greater than 2% of the mild sewage pump clean water or solid impurities; diving depth of no more than 5m;? water temperature no farther than +40 ° C; Technical data Type Rated flow (m3 / h) Rated head (m) Rated power kW rated speed r / min electric pump efficiency% Rated voltage V Rated current A BQW35-7 -2.2 35 7 2.2 2860 38.8 380/660 5.7/3.3 BQW25-10-2.2 25 10 2.2 30 380/660 5.7/3.3 BQW15-15-2.2 15 15 2.2 33.4 380/660 5.7/3.3 BQW12-26-2.2 12 26 2.2 35 380/660 5.7/3.3 BQW10-34-2.2 10 34 2.2 35.8 380/660 5.7/3.3 BQW9-22-2.2 9 22 2.2 30.4 380/660 5.7/3.3 BQW40-12-3 40 12 3 38.6 380/660 7.4/4.4 BQW25-17-3 25 17 3 38.6 380/660 7.4/4.4 BQW12-34-3 12 34 3 31 380/660 7.4/4.4 BQW15-30-3 15 30 3 32 380/660 7.4/4.4 BQW10- 44-3 10 44 3 34.3 380/660 7.4/4.4 BQW12-40-4 12 40 4 30 380/660 9.8/5.6 BQW15-45-4 15 45 4 39.2 380/660 9.8/5.6 BQW25-32-4 25 32 4 48.3 380/660 9.8/5.6 BQW40-16-4 40 16 4 39.8 380/660 9.8/5.6 BQW50-14-4 50 14 4 40.2 380/660 9.8/5.6 BQW12-50-5.5 12 50 5.5 28 380/660 13.1/7.6 BQW15-55-5.5 15 55 5.5 39 380/660 13.1/7.6 BQW20-35-5.5 20 35 5.5 34 380/660 13.1/7.6 BQW25-40-5.5 25 40 5.5 47.5 380/660 13.1/7.6 BQW12- 60-7.5 12 60 7.5 27 380/660 16/9.4 BQW20-40-7.5 20 40 7.5 32.8 380/660 16/9.4 BQW45-22-7.5 45 22 7.5 43.3 380/660 16/9.4 BQW70-16-7.5 70 16 7.5 46.2 380/660 16/9.4 BQW100-12-7.5 100 12 7.5 48.8 380/660 16/9.4
