The role of the screw pump in the industrial field is very important. It can be used in harsh environments such as flammable and explosive, and can complete many tasks that are difficult for humans to do manually, ensuring the safety of the staff and reducing economic losses.

　　Progressive cavity pumps are stable and low cost with pneumatic pumps in flammable and explosive environments, and the fluid will not overheat because the diaphragm pump has minimal agitation of the fluid. In places with bad construction sites, such as construction sites, industrial and mining wastewater discharge, due to the many impurities and complex components in the sewage, the pipelines are easy to block, so that the load on the electric pump is too high, and the motor is easily damaged due to heat. The screw pump can pass particles and the flow rate is adjustable. When the pipeline is blocked, it will automatically stop until it is unobstructed. Screw pumps can be used to transport fluids with relatively unstable chemical properties. In the handling of hazardous and corrosive materials, the screw pump can isolate the material from the outside world.

　　  The screw pump is small in size and easy to move, does not require foundation, occupies a very small area, and is easy and economical to install. Can be used as a mobile material transfer pump. The screw pump does not need irrigation and diversion, 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, no shaft seal, and the pumped medium such as the diaphragm is separated from the moving parts of the pump and the 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.

　　  The screw pump can work submerged in the medium. It is safe and stable to use in flammable and explosive places without using electricity. The screw pump has a simple structure and few wearing parts. The pump has a simple structure and is easy to install and maintain. The medium conveyed by the pump will not touch the moving parts such as the gas distribution valve and the connecting rod. Unlike other types of pumps, the rotor, piston, gear, etc. , blades and other components wear and tear and gradually decline in performance.

　　  The screw membrane pump has six advantages of stable quality, long service life, low noise, small vibration, never crashing, and fine workmanship. It can not only pump flowing liquid, but also transport some difficult-to-flow media. , Canned pumps, mud pumps and impurity pumps have many advantages in conveying machinery. The flow is spacious and the passing performance is good, allowing the passage of large particles with a diameter of up to 10 mm. When pumping mud and impurities, there is little wear on the pump. The head and flow can be adjusted steplessly through the opening of the air valve (air pressure adjustment between 1-7bar).

　　  The screw pump is easy to use, stable in work, and it only needs to simply open and close the gas valve to start and stop. Even if it runs without medium for a long time due to accidents or suddenly stops the pump, it will not be damaged. Once overloaded, the pump will stop automatically. , with self-protection performance, when the load returns to normal, it can automatically start to run; the pneumatic diaphragm pump does not need to be lubricated with oil, even if it is idling, it has no effect on the pump, which is a major feature of the pump. It can transport viscous liquid (viscosity below 10,000 centipoise).

　　  The screw pump can pump all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. The use of screw pumps to transport fuel, gunpowder, and explosives is very stable because: it is impossible to generate sparks after the screw pump is grounded; no heat is generated during the work of the pneumatic diaphragm pump, and the machine will not overheat; the fluid will not overheat because the pneumatic diaphragm pump stirs the fluid minimum.

　　  Since the 1990s, with the rapid development of my country's chemical industry and the domestic market, enterprises and manufacturers have become more demanding and strict on the delivery of corrosive media. The leakage of toxic and corrosive media greatly affects the safety of operators and the pollution of the environment. Pneumatic diaphragm pumps can effectively prevent and solve such problems. Pneumatic diaphragm pumps are very suitable for working environments with high pollution, high danger, strong acid liquid, low noise and clean room. Especially high-tech industries such as printed circuit board (PCB), semiconductor industry, packaging industry, super corrosive transportation and optoelectronic industry are most suitable.

　　  Generally speaking, when transporting special or high-purity media, the unnecessary pollution and waste caused by media leakage should be minimized. If necessary, the above two functions of the electronic-grade pneumatic diaphragm pump can be used to ensure the safety of operators, the environment and The pollution of the medium, so the pneumatic diaphragm pump can be widely used in the transportation of special chemical media, providing a more convenient, safe and efficient solution for enterprises.

　　  The editor believes that in the next few years, the application field of pneumatic diaphragm pumps in China will continue to expand, and its role and value will be played in more places. However, it should also be noted that the pneumatic diaphragm pump must work under defined temperature conditions. If the temperature exceeds the standard, it may cause leakage of the medium and cause an accident. Usually, the surface of the air-operated diaphragm pump is equipped with a temperature sensing device, which will automatically stop operation or issue an early warning indicator when the temperature exceeds the standard. The magnetic distance of the pneumatic diaphragm pump cannot be designed too short, which will easily cause demagnetization and degaussing, and cannot work normally.

　　  From the above content, it can be seen that the pneumatic diaphragm pump can be effectively used in many harsh environments, which is one of the reasons why more and more customers choose pneumatic diaphragm pumps.
