China Pumping Solutions Leader
Diaphragm pump is a comprehensive performance of the new air pump, different pump materials in the performance of the difference, such as mechanical strength and high temperature resistance is very obvious, recently many users in the consultation of plastic pneumatic diaphragm pump resistance to high temperature, the advantages of general engineering plastics are reflected in the excellent corrosion resistance, high temperature tolerance can be below 70℃.
On plastic pneumatic diaphragm pump resistance to high temperature, generally recommended to deal with the temperature below 70℃ medium, if there is a higher demand for high temperature resistance, can consider stainless steel pneumatic diaphragm pump, heat resistance temperature can be up to 150℃. It is worth noting that, in addition to the heat resistance of the pump body material itself, it is also necessary to consider the heat resistance of the diaphragm in the pump, the diaphragm is made of rubber, different materials in the heat resistance performance is different, the details are as follows:
The upper heat resistance temperature of butadiene rubber and neoprene rubber film is 80℃;
The upper heat resistance temperature of PTFE and F46 diaphragm is 180℃.
The upper heat resistance temperature of fluorine rubber film is 200℃.
The above diaphragm is a common material, can help you intuitively understand how high temperature plastic pneumatic diaphragm pump resistance, the user needs to pay attention to is that, although the heat resistance of fluorine rubber diaphragm is very high, but compared with other diaphragm on the production cost is higher, so it is recommended that there is no special high temperature resistance need not be selected. In addition, all the heat resistance values are theoretical values, in the actual work taking into account different manufacturers of different materials and processes, at the same time the transport environment is complex, as well as the medium temperature itself may be variable, so in actual use is not able to reach the theoretical value, it is recommended and select the performance parameters to reserve about 10%-15% of the space.
After the above introduction, I believe you also have a certain understanding of plastic pneumatic diaphragm pump resistance to high temperature, plastic diaphragm pump is not superior in heat resistance, the selection of plastic pump is mainly to take a look at the corrosion resistance and pump cost is relatively low, it is recommended that the user first clear transport project required parameters and environmental temperature changes directly contact the manufacturer to choose the matching pump type
