What are the types of polyurethane foam filter?

Polyurethane foam machine is suitable for automobile interior decoration, heat preservation pipe manufacturing, heat preservation wall spraying, bicycle and motorcycle seat sponge processing. So what are the types of polyurethane foam filter?


1. Circulation filter

The system is located on the return path of the tank circulation and has a large capacity, so it is usually selected when severe cleanliness is required even if the system is not working to collect pollutants in the tank.

2. Oil absorption filter

The filter is located in the pump suction pipe road residual pollutants within the filter tank through air hole into the pollutants have a role to protect the pump, but in order to avoid the pump cavity surface, it is necessary to full of pressure losing general intention by using 100-200 thick metal mesh or notch of wire material, so it is not a filter to determine the concentration of pollution control system.


3. Return flow filter

The effect of the return pipe on the road is located in the system is in attack or invade the system pollutants captured in front of the tank back so it is the pollution concentration control system of the most useful one of the most important filters. Although it was the working condition of low pressure pipeline but according to the transmission equipment also can appear pulsating or pressure shock strength of component material, so want to consider to import pump energy.

4. High-pressure pipeline filter

1. The outlet pipe of the pump has the function of protecting pollutants from entering the system, so the pollutant concentration of the system can be controlled. However, the material strength of the filter elements should be carefully considered because the high-pressure main road should be subject to the pulse and pressure impact of the pump.

2 in the system in order to protect the pollution of particularly sensitive hydraulic components equipment this filter is also known as the terminal filter, so it is generally smaller than other filters filter particle size so the use of large capacity to choose.
