QYF14-20 mine pneumatic dredging sewage pumps, QYF14-20 pneumatic dredging sewage pump, QYF series of intelligent energy efficient mining pneumatic dredging sewage pumps, sewage pumps pneumatic dredging, mining dredging pump, QYF mine clearance slurry pumps, coal dredging pumps, pneumatic dredging pumps, dredging pumps Pneumatic Introduction QYF series of intelligent energy-efficient mine pneumatic pump dredging is our own innovation, independent research and development, intellectual property rights of the series dredging equipment technology products in the international advanced level. This series of pumps used in the mining industry as a driving force of compressed air, according to the principle of the Venturi effect, designing efficient vacuum generator components, to achieve secondary use of compressed air circulation, so that products in both excellent performance on the basis of reduced energy consumption. Boot to achieve full unattended or single easy operation, greatly liberated the labor force and reduce production costs. Products designed for pumping high solids content of the material, for bearing rock, slag, wood, metal and other solid particles of mud, coal slurry high concentration slurry have a good treatment effect, very suitable for coal slurries, oil-based mud concrete waste, municipal sewage, bauxite mud, river dredging and other fields. Dredging equipment to use more conventional electric or internal combustion engine driven, moving parts and are in direct contact with the waste clean-up media, badly worn, high failure rate, life expectancy is low, not only gives users a lot of equipment maintenance, updates and other materials, and the overall result inefficiency, but for security reasons, and it is also very limited range of applications. And I developed dredging sewage pumps, mining industry often uses compressed air as a driving force in the no-load and overload the unit is running on the device without any damage. At the same time there is no tradition of similar equipment impeller rotating parts when the device is working, moving parts and is completely separated from the transportation of materials, so that the device has the ability through solid, stable operation and high efficiency, greatly reducing the maintenance cost of the equipment; and that the device is moved flexible, extremely wide range of transmission media, you can achieve a multi-purpose machine functions, saving the user a lot of cost and manpower. The successful development of the dredging crew not only to fill the gaps in some areas of domestic equipment, but similar to existing equipment also has a strong alternative for the petroleum, chemical, coal, municipal, construction and other industries to provide a dredging equipment new choice to break the monopoly of foreign companies, the market prospect. Advantages and Features · Over sewage ability to pump liquidity has a high solids content materials · pure pneumatic products, without any electronic devices, safe and reliable. · Unit compact, cleverly designed, can be automatically run. · No moving parts in contact with the material, no wear, stable operation, long service life. · Load or overload the equipment without injury, and simple maintenance. Small size, light weight, mobile and flexible, easy to operate, wide range. · Energy consumption, energy saving products use conditions: a) by suction dredging pump intake pipe submerged. b) transport medium temperature does not exceed 40 ℃. c) Operating ambient temperature (5 ~ 40) ℃. d) PH transmission medium within the range of 4 to 10. e) the maximum diameter of solid particles containing no more than 20mm. e) applies pressure range 0.60MPa ~ 0.70Mpa.
