　　Mining air pump, submersible sewage and sand removal air pump, pneumatic water pump, coal mine pneumatic submersible pump

　　nowadaysMining air pump, submersible sewage and sand removal air pumpThe competition between enterprises is not only the competition between products, but also the competition between business models and prices, such asPrice of Pneumatic Submersible Pump for Coal Mines with Pneumatic Water PumpThis is a topic that many customers are directly concerned about. There are many models of pneumatic submersible pumps used in mines based on different flow rates and head, and their prices are also determined by their models.

　　Mining air pump, submersible sewage and sand removal air pumpIt is also divided into blade type and turbine type.

　　Turbo typePneumatic submersible pump for coal minesIt is a new type of submersible pump that adopts pneumatic turbine transmission and compressed air power according to the actual needs of mining site construction in China. Widely used for the development of mine shafts, construction of vertical shafts, discharge of clean water, turbid water, sediment, mud water, and various slag water from underground chambers and mining faces. The pump is equipped with advanced noise reduction devices, which can reduce the noise level to below 40 decibels. In addition, the pump has a small volume, light weight, and high head; Compact structure, easy to move; Durable and easy to maintain.

　　Blade typePneumatic submersible pump for coal minesThe pneumatic motor part is composed of rotor, blades, cylinder, housing, upper and lower cylinder heads, top cover, etc. There are five evenly distributed radial grooves on the rotor, which are equipped with blades. There is a blowing eye on each of the upper and lower cylinder heads. When the air pump is started, high-pressure air blows open the blades in the grooves through the blowing eye, and a large amount of high-pressure air enters the cylinder from the main air duct, pushing the blades and driving the rotor to rotate and work. There is a sealed chamber below the shell, which is separated from air and water by a sealing ring. The sealing ring adopts spring sealing and utilizes the pressure of air and water to expand inside the sealing ring, enhancing the sealing effect

　　Mining air pump, submersible sewage and sand removal air pumpStructural characteristics and working principle

　　1) The working principle of the air pump is to convert the potential energy of compressed air into kinetic energy in the form of supersonic airflow through a pull nozzle, drive a single-stage re-entry impact turbine, and rotate the water pump impeller through the pump shaft to achieve the purpose of drainage.

　　2) The rotor of the air pump is supported by three closed bearings (two at the bottom), with a simple structure, smooth operation, and excellent performance, ensuring high-speed operation within the rated range.

　　3) The pump is equipped with a centrifugal speed limiter. If the accumulated water is drained or the inlet cover is blocked, the pump speed will increase sharply. At this time, the speed limiter will take effect to control the speed and avoid bearing damage.

　　4) The nozzle, turbine, and airflow re entering the power section have undergone scientific aerodynamic calculations and experiments, and have good aerodynamic characteristics.

　　5) InPneumatic submersible pump for coal minesWhen operating at rated conditions, the re-entry chamber structure of a single-stage re-entry impact turbine can redirect the airflow sprayed by the Lasseter nozzle, which has passed through the turbine blades for one work, back to the turbine for two work, increasing aerodynamic efficiency and compressed air utilization.

　　6) The shaft seal part of the shell is sealed by two skeleton oil seals, which use water and gas pressure to expand the sealing ring and increase the sealing effect.

　　7) The exhaust gas is discharged through a well-designed soundproof cover, significantly reducing the unique mid to high frequency noise of the turbine wind motor and improving the noise environment at the work site.

　　8) The turbine adopts a high-efficiency hydraulic model that is compatible with the turbine motor, resulting in a significant improvement in pump performance.

　　9) The power part and pump body adopt a separate structure, which facilitates the replacement of the pump body, water wheel, and sealing device.

　　nowadaysMining air pump, submersible sewage and sand removal air pumpThe crisis of chaos not only brings trouble, but also contains opportunities, and service is particularly important,Pneumatic submersible pump for coal minesThe price is no longer enough to explain any problem, choosing a practical solution that suits oneself is the most important.
