BQS (W) series flameproof submersible sewage pump sediment ★ Product Description: BQS series flameproof submersible pump sewage sediment is my company and Jiangsu University jointly developed, complete product specifications, power range from 2.2kW ~ 315kW, flow range from 10m3 / h to 2500m3 / h, head range from 7m to 700m, all the products are to achieve a full head, no overload. Company perseverance of product innovation to solve the submersible pump sewage sediment in the product structure, parameter optimization, key technical issues manufacturing processes, operational efficiency, leak-proof seal, materials and other aspects of the application, has more than 20 patents , the application of a number of the latest research results, the formation of a mature motor, pump manufacturing process, and similar domestic product, compared with a safe, reliable, lightweight and practical, good sewage sediment performance, long life, type spectrum reasonable selection and easy. ★ main purposes: for coal mine methane (commonly known as gas) and coal dust explosion hazard sites, containing sediment transport, coal, coal gangue, coal cinder, etc. Insoluble fiber solid phase mixing of sewage. Also apply to the construction of buildings, hospitals, residential areas, municipal engineering, road traffic and construction, sewage plants, sewage treatment and other occasions small carriage containing solid particles, long fiber wastewater, rainwater and sewage. ★ Use Conditions: 1, Power 380V or 660V or 1140V, three-phase, 50HZ. 2, medium temperature generally does not exceed 40 ℃, PH value 5-9, medium and severe ≤ 11kN/m3 3, diameter size medium solids shall comply MT / T 671-2005, reminding special requirements when ordering. ★ model composition and what they mean: BQS ① - ② / ③ - ④ ⑤ BQS: flameproof submersible pump sewage sediment ①: Rated flow, in cubic meters per hour (m3 / h) ②: Rated Yang Cheng, in units of (m) ③: series ④; motor rated power in kilowatts (KW) ⑤: N is built-in; B is a semi-built-in; exterior does not note ★ salient features: 1, Model Screening: Performance optimized to run smoothly without clogging sewage sediment strong ability to pump has no overload (full head) characteristics, namely the use of input power at any operating point no more than matching motor power. For a coal mine on various occasions, to a machine. 2, mechanical seal improvements: using an independent tandem mechanical seals and double mechanical seal. 3, structural optimization: design win in the mechanical seal tightness, smooth operation, high reliability; optimized design, the use of more portable, low energy consumption. In the case of water, long dry run. 4, IPx8 motor protection chip level, submersible motor cooling effect, low temperature than ordinary motor. Further improve durability, F class insulation procure motor last longer. ★ Structure Description: The overall structure for the vertical pump, the whole dive, mechanical and electrical integration, downdraft absorbent, able to face drained drained shallow layer of surface water. Most products are mainly made up of two flow components and motor components. Pump discharge flow structure by the way can be divided into exterior style, interior, semi built-in.
