The screw pump plays a very important role in the industrial field. It can be used in harsh environments such as flammable and explosive, and can complete many tasks that are difficult for humans to complete manually, ensuring the safety of workers and reducing economic losses.
The screw pump causes minimal agitation of the fluid, the fluid will not overheat, and it operates stably and at low cost in flammable and explosive environments. It can be used to transport fluids with relatively unstable chemical properties. In the handling of hazardous and corrosive materials, screw pumps can isolate the materials from the outside world.
The screw pump is small and easy to move, does not require a foundation, occupies a very small area, and is easy and economical to install. It can be used as a mobile material transfer pump without water filling. The suction lift is up to 5 meters, the lift is up to 70 meters, and the outlet pressure is ≧7bar. The screw pump has no rotating parts, and no shaft seal, and the pumped medium such as the diaphragm is separated from the pump’s moving parts and workpiece medium, and the transported medium will not leak outward. Therefore, when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and endanger personal safety.
Screw pumps can work immersed in the medium. No need to use electricity, it is safe and stable to use in flammable and explosive places. The pump has a simple structure and is easy to install and maintain. The transported medium will not come into contact with moving parts such as valves and connecting rods. Unlike other types of pumps, the performance gradually declines due to wear and tear of rotors, pistons, gears, blades and other components.
It has six major advantages: stable quality and long service life, low noise, low vibration, never crashing, and fine workmanship. It can pump flowing liquids and transport some non-flowing media. It has self-priming pumps, submersible pumps, and canned pumps. , mud pumps impurity pumps and other conveying machinery have many advantages. The flow is spacious and the passing performance is good, allowing the passage of large particles up to 10 mm in diameter. When pumping mud and impurities, there is little wear on the pump. The lift and flow rate can be adjusted steplessly through the opening of the air valve (the air pressure can be adjusted between 1 and 7 bar).
The screw pump is easy to use and works stably. To start and stop, you only need to simply open and close the gas valve. Even if it runs without medium for a long time or stops suddenly due to unexpected circumstances, the pump will not be damaged. Once overloaded, the pump will automatically stop. , with self-protection performance, it can automatically start operation again when the load returns to normal. No need for oil lubrication, even if it is idling, it will not have any impact on the pump and can transport relatively viscous liquids.
