　　qyw30-70Pneumatic submersible pumpOverview:

　　Pneumatic sand removal and sewage submersible pumpThe new type of high lift drainage tool, the pneumatic turbine submersible pump, is mainly suitable for mining development, excavation of tunnels and vertical shaft construction drainage operations.

　　qyw30-70Pneumatic submersible pumpEnvironmental conditions for use:

　　1. The surrounding air contains gas and coal dust;

　　2. The air pressure is (0.4-0.7) MPa;

　　3. The pH value of water is within the range of 4-10;

　　four Pneumatic sand removal and sewage submersible pumpThe volume ratio of solid impurities in water exceeds 2%;

　　5. The density of water shall not exceed 1.1x103kg/m3;

　　6. Working environment temperature (5-40) ° C

　　qyw30-70Pneumatic submersible pumpStructural features:

　　1. Pneumatic motor part: composed of rotor, blades, cylinder, housing, upper and lower cylinder heads, top cover, etc. There are four 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 pressure of air and water is used to expand the sealing ring and enhance the sealing effect.

　　two Pneumatic sand removal and sewage submersible pumpPump body: composed of pump body, impeller, pump cover, pump seat, etc. The impeller is mounted on the rotor shaft, tighten the impeller nut, and install the pump body and pump seat.

　　3. Oil Mist Unit: It consists of an oil mist unit housing, oil mist unit core, oil regulating valve, etc. The oil mist unit is installed on the top cover, and the housing is filled with lubricating oil.

　　4. Muffler section: A new type is installed at the exhaust outlet.

　　qyw30-70Pneumatic submersible pumpPay attention to the following matters

　　1. Before using the pneumatic submersible pump, it is necessary to conduct a ground load test run. When the wind speed is 0.6mpa, the pump should work for about ten minutes to check if it is running normally.

　　2Pneumatic sand removal and sewage submersible pumpWhen using a rubber hose with an inner diameter of 50mm to connect with the drainage pipe and a rubber hose with an inner diameter of 25mm to connect with the pump inlet pipe, attention should be paid to the cleanliness of the pipe joints to avoid the entry of gangue powder into the pump.

　　3. When the operation is normal, but the flow rate decreases or there is no water supply, it is necessary to disassemble, repair or replace the parts. Do not use hammers, picks or other objects to strike the pump casing

　　4. When assembling the turbine cover after maintenance, attention should be paid to aligning the nozzle outlet with the reverse chamber arc of the pump body, otherwise the efficiency will be low.

　　5. The pump uses GB491-87II calcium based lubrication. After running for about 300 hours, it should be disassembled, cleaned, and oiled. When not in use, it should be protected and oiled.

　　6Pneumatic sand removal and sewage submersible pumpIt is strictly prohibited to operate without load. Due to the use of friction wheels to limit the speed of the pump, idling can cause an increase in frictional heating temperature and damage to parts, leading to accidents.

　　qyw30-70Pneumatic submersible pumpFeatures:

　　1. Stepless speed regulation. As long as the throttle valve opening program is controlled, that is, the gas flow rate is controlled, stepless speed regulation can be achieved.

　　2. Reliable to use, durable, not affected by temperature and vibration, easy to install and operate.

　　3. Equipped with a silencing device, it has low noise, easy maintenance, and small vulnerable parts.

　　4Pneumatic sand removal and sewage submersible pumpIt has a high starting torque and the ability to work at full speed almost instantaneously.

　　5. Strong adaptability. Suitable for discharging clean water and turbid water (mud, sand, coal slag water), lightweight.
