Product Description
BQS series flameproof sewage desilting submersible pump is my company 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 products are to achieve a full head, without overload. Company perseverance product of technical innovation to solve the sewage sediment submersible pump in the product structure, parameter optimization, key technical problems manufacturing processes, operational efficiency, leak-proof seal, materials, applications, etc., over twenty patents the application of a number of the latest research results, the formation of a mature motor, pump manufacturing process, and compared to similar products are safe and reliable, lightweight and practical, good sewage sediment, long life, reasonable spectrum, selection and easy.
★ main purposes:
For coal mine methane (commonly known as gas) and coal dust explosion hazard areas and contains a mixture of sewage and sediment transport, coal, coal gangue, coal cinder, fibers and the like insoluble solid phase material. Also apply to construction of buildings, hospitals, residential areas, municipal engineering, traffic and construction, sewage plants, small sewage treatment and other occasions carriage containing solid particles, long fiber waste water, rainwater and sewage.
★ Conditions of Use:
1, power supply 380V or 660V or 1140V, three-phase, 50HZ.
2, medium temperature usually does not exceed 40 ℃, PH value 5-9, medium and severe ≤11kN / m³
3, medium diameter solids should be consistent with the provisions of MT / T 671-2005, reminding special requirements when ordering.
BQS2.2kW~315kW full-lift flame-proof sewage & desilting mixing pump for mine is a high efficiency energy saving product aiming at coal mines with a mass of coal slurry according to MT/T671-2005 criterion. It is jointly developed with Jiangsu University based on the former flame-proof sewage & desilting submersible electric pump for mine. Depending on innovative design, this product acts as electromechanical integration equipment with a stirrer at the bottom of pump body to effectively transport sewage containing coal slurry and sand from coal mines. Two patented techniques of Jiangsu University are adopted in this series of product, through which the hydraulic part, i.e. impeller and volute is designed into the type of double passage with outlet width of impeller blade more than 30mm to ensure the sewage discharge capacity and blade curve of impeller is modified to ensure the non-overload performance, thus it provides convenience for users that one motor serves several purposes and modified curve saves 10% energy for users. To be capable to operate in case of little water or even waterless, this product is designed into forced cooling sandwich structure. So this series of submersible electric pump can meet the demand of coal mines. Compared with domestic similar products, this pump has features as advanced technique, outstanding performance, energy-saving.
The technical parameters of the flame-proof sewage & desilting mixing pump for mine refer to the technical parameters of flame-proof sewage & desilting submersible electric pump for mine with corresponding power and model.
BQG pneumatic diaphragm pump for mining
★ Product description:
The BQG series pneumatic diaphragm pump for mining is a new pneumatic product out of our independent innovation and development and with proprietary intellectual property right. The technology adopted has played a leading role in China and come up to the world’s advanced level. The BQG series pneumatic diaphragm pump for mining is a high-quality self-priming pump with forward displacement. The product, powered by the compressed air commonly used by industrial and mining enterprises, utilizes the inhaled liquid pressure and the positive liquid pressure as generated alternately in the liquid chamber through the pressure difference in the air chamber so as to control the switch of ball non-return valve and to ensure the positive flow of liquid. The pneumatic pump body / fluid part of the pump adopts the anti-stalling and modularized design and is free of dead points, which effectively eliminate such technical problem as undesirable movement of the valve element of the original diaphragm pump. Pneumatic diaphragm pump is a new type of conveying machine. Its core component is made of aluminum alloy and its diaphragm, ball and ball seat are made of internationally advanced materials and are characterized by light weight, small size, low noise, easy operation, reliable operation, resistance to abrasion and corrosion, and prevention against fire and explosion. The product is especially fit for application in such fields as mine, underground tunnel, tunnel engineering, petroleum and chemical engineering. Besides, pneumatic diaphragm pump also has the function of immersible pump, self-priming pump, trash pump, shield pump, and slush pump. Coming into extensive use, the product meets the needs of different users and can convey different media. Up to now, it has become a main substitute for silent pneumatic submersible pump.
★Environmental conditions
a)Capable of conveying any flowable materials; the medium concentration (volume ratio) shall be no higher than 15%;
b)The maximum diameter of solid particles shall be no higher than 9mm;
c)Operating ambient temperature:5-50℃;
d)PH of transmission media: 6-8;
e)Temperature of transmission media: no higher than 50℃;
f)Range of applicable air pressure:0.4MPa~0.8MPa。
★ Advantages and characteristics of product:
1. Low energy consumption, energy saving and environmental protection;
2. Small size, low weight, easy operation and wide application;
3. Pure pneumatic product- safe and reliable;
4. Capable of idle and overlond running and without damage to equipment;
5. Reciprocating motion, high service efficiency and without stoppage.

FQW (original FWQB) pneumatic immersible pump for mining
★ Product description:
FQW (original BQF and FWQB) pneumatic immersible pump for mining is a new product out of our independent development. This device is a mechanical product through the coaxial linkage of rotor and pump body and applies the vertical mechanism and down pump. Standard Q/JNAT001-2010 has been implemented. The pneumatic immersible pump for mining exhibits compact structure and is easy to move, assemble, disassemble and repair. The vortex street of pump applies efficient, energy-saving hydraulic model and specially designed impeller. This water pump is characterized by great sewerage disposal ability, large flow, high head of delivery, etc. FQW pumps are applicable to the drainage in places with hidden danger of gas and coal-dust explosion and have come into wide use in any working planes under the coal mine shafts. The product, easy and reliable to operate, functions to convey the underground water containing coal dust and sand grain and can improve the on-site air quality in an effective way.
★Characteristics of FQW pump:
The FQW (original BQF) pneumatic immersible pump for mining, powered by compressed air and with the centrifugal pump structure, exhibits small size, light weight, simple structure and easy installation and repair. As a cutting-edge pneumatic pumping appliance, the device can be used safely and reliably in mines containing gas and coal dust.
