Screw pumps can also be used effectively in harsh environments

The role of screw pump in the industrial field is very important, it can be used in flammable and explosive and other harsh environments, complete a lot of human manual difficult to complete the work, to ensure the safety of staff, reduce economic losses.

Screw pump in flammable and explosive environment with pneumatic pump stability and low cost, the fluid will not overheat because the diaphragm pump to the fluid agitation is minimal. In the harsh place of the construction site, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and complex composition, the pipeline is easy to block, so that the electric pump will form an excessive load, and the motor is easy to lose heat. The screw pump can pass the particle and the flow rate is adjustable, and the pipeline is automatically stopped to smooth when blocked. Screw pumps can be used to transport fluids with relatively unstable chemical properties. In hazardous, corrosive material handling, screw pump can separate the material from the outside world.

The screw pump is small and easy to move, does not require foundation, occupies very little ground, and is simple and economical to install. Can be used as mobile material transfer pump. Screw pump does not need to fill water, suction up to 5 meters, head up to 70 meters, outlet pressure ≧7bar. The screw pump has no rotating parts, no shaft seal, diaphragm and other pumping media are separated from the moving parts of the pump and the workpiece media, and the conveyed media will not leak outwards. Therefore, when pumping toxic, volatile or corrosive media, it will not cause environmental pollution and harm personal safety.

Screw pump can be immersed in the medium to work. No need to use electricity, safe and stable in flammable and explosive places. Screw pump simple structure, less wearing parts, the pump structure is simple, easy to install, maintenance, pump transport medium will not contact the valve, rod and other moving parts, unlike other types of pump due to rotor, piston, gear, blade and other parts wear and performance gradually decline.

Screw film pump has a stable quality of long service life, noise bottom, small vibration, never crash, fine work and other six advantages, that is, can pump flowing liquid, but also can transport some difficult to flow medium, with self-priming pump, submersible pump, shield pump, mud pump and impurity pump and other conveying machinery many advantages. The flow is spacious and good through performance, allowing the passage of large particles up to 10 mm in diameter. Little wear to the pump when pumping mud and impurities. The head and flow can be adjusted stepless by the opening of the air valve (the air pressure is adjusted between 1-7bar).

Screw pump easy to use, stable work, open and stop simply open and close the gas valve, even if due to unexpected circumstances for a long time without medium operation or sudden stop pump will not be damaged, once overload, the pump will automatically stop, with self-protection performance, when the load returns to normal, and can automatically start operation; Pneumatic diaphragm pump does not need oil lubrication, even if idling, there is no effect on the pump, which is a major feature of the pump. It can transport viscous liquid (viscosity below 10,000 cm).

Screw pump for a variety of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, highly toxic liquids, can be pumped out. The use of screw pump to transport fuel, gunpowder, explosives is very stable because: screw pump ground can not produce sparks; Pneumatic diaphragm pump work without heat generation, the machine will not overheat; The fluid does not overheat because the pneumatic diaphragm pump has minimal agitation of the fluid.

Since the 1990s, the rapid development of China's chemical industry and the domestic market, enterprises and manufacturers are more demanding and stringent for corrosive media transportation. The leakage of toxic and corrosive media greatly affects the safety of operators and the pollution of the environment. Pneumatic diaphragm pump can effectively prevent and solve such problems. Pneumatic diaphragm pumps are ideal for high pollution, high risk, strong acid, low noise and clean room working environments. In particular, the printed circuit board (PCB), semiconductor industry, packaging industry, super corrosive transportation and optoelectronics industry and other high-tech industries are suitable.

In general, in the transmission of special or high purity media as much as possible to reduce the media leakage caused by unnecessary pollution and waste, if necessary, by using the electronic grade pneumatic diaphragm pump in the above two functions to ensure the safety of the operator, the environment and media pollution, so the pneumatic diaphragm pump can be widely used in the transmission of special chemical media, to provide enterprises with a more convenient, Safe, efficient solutions.

Xiao Bian believes that in the next few years, the application field of pneumatic diaphragm pump in China will continue to expand, and play its role and value in more places. However, it should also be noted that the pneumatic diaphragm pump should work under defined temperature conditions, and if the temperature exceeds the standard, it is likely to to media leakage, causing accidents. Under normal circumstances, the surface of the pneumatic diaphragm pump is equipped with a temperature sensing device, which will automatically stop operation or issue early warning instructions in the case of excessive temperature. The magnetic distance of the pneumatic diaphragm pump can not be designed too short, which is easy to cause demagnetization and demagnetization, and can not work normally.

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